The area of a triangular flag is 330 square centimeters. If the base of the triangle is 30 centimeters long, what is the height of the triangle?
Answers
The height of the triangle is 22 centimeters. When The area of a triangular flag is 330 square centimeters
To find the height of the triangle, we can use the formula for the area of a triangle, which is given by:
Area = (1/2) * base * height
where "base" is the length of the base of the triangle, and "height" is the height of the triangle.
Given that the area of the triangular flag is 330 square centimeters and the base is 30 centimeters, we can plug these values into the formula and solve for the height:
330 = (1/2) * 30 * height
To find the height, first, multiply 30 by (1/2):
330 = 15 * height
Now, divide both sides of the equation by 15 to solve for the height:
height = 330 / 15
height = 22
So, the height of the triangle is 22 centimeters.

a. Both expressions are equivalent to 78 when t=6.
b. Both expressions are equivalent to 81 when t=6.
c. Both expressions are equivalent to 48 when t=4.
d. The expressions are equivalent.
Answers
Answer:
Both expressions are equivalent to 78 when t = 6 ⇒ answer A
Step-by-step explanation:
* To solve this problem substitute the value of t and then check
the answer
∵ The first expression is 2(7t - 3) ⇒ simplify it
# 2(7t) = 14t
# 2(3) = 6
∴ 2(7t - 3) = 14t - 6
- Substitute t by 4
∴ 14t - 6 = 14(4) - 6 = 56 - 6 = 50
- Substitute t by 6
∴ 14t - 6 = 14(6) - 6 = 84 - 6 = 78
∵ The second expression is 15t - 12
- Substitute t by 4
∴ 15t - 12 = 15(4) - 12 = 60 - 12 = 48
- Substitute t by 6
∴ 15t - 12 = 15(6) - 12 = 90 - 12 = 78
- The first expression has two values
# 50 when t = 4
# 78 when t = 6
- The second expression has two values
# 48 when t = 4
# 78 when t = 6
- From these information
# The two expressions have the same value 78 when t = 6
∴ Both expressions are equivalent to 78 when t = 6

Answer:
No, the ladder will not be save at the height 16.5 feet from the ground
She must to buy 9 rolls to have enough crepe papers to decorate her ceiling
Step-by-step explanation:
* Lets change the story problem to mathematics information
- The ladder , the wall and the ground formed together a right
angle triangle
- The wall and the ground are perpendicular to each other
- The length of the ladder is the hypotenuse of the triangle
- The vertical height of the ladder is the vertical leg of the triangle
- The horizontal distance between the ladder and the vertical wall
on the ground is the horizontal leg of the triangle
* Lets revise the trigonometry functions
- In any right angle triangle:
# The side opposite to the right angle is called the hypotenuse
# The other two sides are called the legs of the right angle
* If the name of the triangle is ABC, where B is the right angle
∴ The hypotenuse is AC
∴ AB and BC are the legs of the right angle
- ∠A and ∠C are two acute angles
- For angle A
# sin(A) = opposite/hypotenuse
∵ The opposite to ∠A is BC
∵ The hypotenuse is AC
∴ sin(A) = BC/AC
# cos(A) = adjacent/hypotenuse
∵ The adjacent to ∠A is AB
∵ The hypotenuse is AC
∴ cos(A) = AB/AC
# tan(A) = opposite/adjacent
∵ The opposite to ∠A is BC
∵ The adjacent to ∠A is AB
∴ tan(A) = BC/AB
* Lets solve the problem
- We need to calculate the measure of the angle between the
ladder and the ground, let it called Ф
- The vertical height is the opposite to this angle Ф
- The hypotenuse is the length of the ladder
∵ We have the opposite and the hypotenuse, we can use
the sin function
∵ sin(Ф) = opposite/hypotenuse
∵ The opposite is the vertical height = 16.5 feet
∵ The hypotenuse is the length of the ladder = 17 feet
∴ sin(Ф) = 16.5/17
∴ Ф = [tex]sin^{-1}\frac{16.5}{17}=76.1[/tex] dgree
- The ladder will be save if the angle between the ladder and
the ground is no more than 70°
∵ The angle between the ladder and the ground is 76.1°
∴ Its measure is greater than 70°
* The ladder will not be save at the height 16.5 feet from the ground
* Lets study the information in the problem
- Katie wants to put the crepe paper around the perimeter of the
ceiling which shaped a square of side length 12 feet
- And also from each corner to the opposite corner
- She needs the length of the 4 sides of the square and the length
of its 2 diagonals
* Lets find the length of the diagonal of the square
∵ The two adjacent sides of the square formed two legs of a right
angle triangle and the diagonal joining the endpoints of the legs
is the hypotenuse of the triangle
- Use Pythagoras theorem to find the length of the diagonal
∴ The length of the diagonal = √(s² + s²) √(2s²) = s√2
∵ The length of the side of the square = 12 feet
∴ The length of the diagonal = 12√2
* Now lets find the length of the crepe papers she needs
∵ She needs the length of the 4 sides of the square and the length
of its 2 diagonals
∴ The length of crepe papers = 12 + 12 + 12 + 12 + 12√2 + 12√2 = 81.94 feet
∵ Each roll of the crepe papers contain 10 feet
- To find the number of rolls divide the length of the crepe papers by 10
∴ The number of rolls = 81.94 ÷ 10 = 8.194
* She must to buy 9 rolls to have enough crepe papers to decorate
her ceiling
* V.I.N:
- If she decide to buy 8 rolls, some part of ceiling will not decorate
because the 8 rolls have 80 feet only and she needs 81.94 feet

A clothing store sells T-shirts, t, for $8 a shirt; shorts, s, for $12; and hats, h, for $10 each. The store earned $406 in revenue last month. The store sold three times as many T-shirts than hats, and twice as many shorts as hats. Using the substitution method, how many T-shirts, shorts, and hats did the store sell?
Answers
Step-by-step explanation:
From the total revenue, we know that:
8t + 12s + 10h = 406
We're also told:
t = 3h
s = 2h
If we substitute these for t and s:
8 (3h) + 12 (2h) + 10h = 406
24h + 24h + 10h = 406
58h = 406
h = 7
Now we can find t and s:
t = 3h = 21
s = 2h = 14
The store sold 21 T-shirts, 14 shorts, and 7 hats.
The clothing store has sold a total of 21 t-shirts, 7 hats, and 14 shorts.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given,
T-shirts, t, for $8 a shirt; shorts, s, for $12; and hats, h, for $10 each and stored earn $406
So,
8t + 12s + 10h = 406
And
the store sold three times as many T-shirts than hats
So,
t = 3h
And
twice as many shorts as hats.
s = 2h
By substituting t and s into the equation first
8(3h) + 12(2h) + 10h = 406
h = 7
Now
t = 21 and s = 14.
Hence, The clothing store has sold a total of 21 t-shirts, 7 hats, and 14 shorts.

The two prisms below are similar. What is the value of x?
A. 30
B. 1
C. 9
D. 3
Answers
Answer:
D. 3
Step-by-step explanation:
If the prisms are said to the similar, that means that the ratio/relation between their corresponding sides have to equal, so
[tex]\frac{x}{1} = \frac{9}{3} = \frac{30}{10}[/tex]
We can easily use the part x/1 = 9/3 to make a cross-multiplication that would give us:
x = (1 * 9) / 3 = 9/3 = 3
So, the green prism is a dilated version of the blue one by a dilation/scale factor of 3.
As a math teacher, I would guide you through solving the problem of finding the value of \( x \) for two similar prisms. However, without specific information about the measurements of the prisms, we can't calculate this value. Similarity in prisms implies that corresponding lengths are proportional, but without knowing these lengths or their ratios, we can't determine \( x \).
However, let's assume you have provided the dimensions for both prisms. For similar prisms, the ratio of any two corresponding linear measurements (such as the height, width, or depth) is the same. If we were given that the ratio of a pair of corresponding dimensions is 1:3, for example, then all other pairs of corresponding dimensions would also have a 1:3 ratio.
Here's a typical process to follow if you had the dimenions:
1. Determine the ratio of corresponding lengths:
Suppose for the smaller prism, a certain length is given as 'a', and for the corresponding length on the larger prism, the length is given as '3a' (implying a 1:3 ratio for the sides).
2. Apply the ratio to unknown lengths:
If 'x' is an unknown length on the larger prism and its corresponding length on the smaller prism is given as some value 'b', then we set up the proportion \( \frac{b}{x} = \frac{1}{3} \).
3. Solve for 'x':
To find 'x', you would solve the proportion by cross-multiplying and dividing as necessary, \( x = 3b \).
However, since we don't have actual numbers here, we can't follow these steps. To answer this question, I would need specific lengths for the corresponding sides of the prisms. Once provided, I can demonstrate the mathematical process to find \( x \). For now, there is not enough information to solve for \( x \), and none of the options A, B, C, or D can be verified as correct.

What is the standard deviation for the data set?
359, 320, 365, 310, 349, 351, 310, 314, 364
Express your answer as a decimal to the nearest tenth
Answers
Answer:
The standard deviation is 22.6 to the nearest tenth
Step-by-step explanation:
* Lets study how to find the standard deviation (σ) for data set
- First step find the mean of the data
∵ The mean = the sum of the data ÷ the number of the data
# The sum of the data is
359 + 320 + 365 + 310 + 349 + 351 + 310 + 314 + 364 = 3042
# The number of the data is 9
∴ The mean = 3042 ÷ 9 = 338
- Second step find the difference between each data and the mean
and square the difference
# 359 - 338 = 21 ⇒ (21)² = 441
# 320 - 338 = -18 ⇒ (-18)² = 324
# 365 - 338 = 27 ⇒ (27)² = 729
# 310 - 338 = -28 ⇒ (-28)² = 784
# 349 - 338 = 11 ⇒ (11)² = 121
# 351 - 338 = 13 ⇒ (13)² = 169
# 310 - 338 = -28 ⇒ (-28)² = 784
# 314 - 338 = -24 ⇒ (-24)² = 576
# 364 - 338 = 26 ⇒ (26)² = 676
- Third step find the variance (σ²)
# Add all the square difference and divide the sum by the
number of data
∴ σ² = (441 + 324 + 729 + 784 + 121 + 169 + 784 + 576 + 676) ÷ 9
∴ σ² = 4604 ÷ 9 = 511.5555556
- Fourth step find the standard deviation σ it is the square root of
the variance
∴ σ = 22.6 to the nearest tenth
* The standard deviation is 22.6 to the nearest tenth

Find the angles of a rhombus if the ratio of the angles that the diagonals form with a side is 6:9.
Answers
Answer:
The measures of the angles of the rhombus are 72° , 108° , 72° , 108°
Step-by-step explanation:
* Lets revise the properties of the rhombus
- It has 4 equal sides
- Each two opposite angles are equal
- Each two adjacent angles are supplementary (their sum = 180°)
- The diagonals are perpendicular to each other
- The diagonals bisect the vertices angles (divide each vertex into two
equal parts)
* Now lets solve the problem
- Let the name of the rhombus is ABCD
- The two diagonals are AC and BD
- Let the diagonals AC and BD make the angles BAC and ABD with
side AB
∵ The diagonals of the rhombus bisect the vertex angles
∴ m∠BAC is half m∠A
∴ m∠ABD is half m∠B
- There is a ratio between the measures of the angles BAC and ABD
∵ m∠BAC : m∠ABD = 6 : 9
∵ m∠A + m∠B = 180° ⇒ consecutive angles
∴ m∠BAC + m∠ABD = 1/2 × 180° = 90°
∵ m∠BAC : m∠ABD : their sum
6 : 9 : 15⇒(6 + 9)
? : ? : 90° ⇒(the sum of the angles)
∴ m∠BAC = 6/15 × 90° = 36°
∴ m∠ABD = 9/15 × 90° = 54°
∵ m∠BAC is half m∠A
∴ m∠A = 36° × 2 = 72°
∵ m∠ABD is half m∠B
∴ m∠B = 54° × 2 = 108°
* The measures of the angles of the rhombus are 72° , 108° , 72° , 108°

Which box plot represents a set of data that has the least mean absolute deviation?
Answers
Answer:
try the second one because it is the smallest and close togehet so maybe that means that the mean is closer to the number and it nots some outlier.
Step-by-step explanation:
If the box plot or the distribution is spread out then the mean absolute deviations i.e. MAD is high.
and if the box plot is clustered that is the distribution is less spread out that is all the data values are close to the center value then the mean absolute deviation i.e. MAD is small.
From the given four box plot we see that the second box plot is less spread and the data values are close to the mean of the data.
Hence, it will lead to the least Mean absolute deviation.

What is the total area of the prism?
Answers
Answer:
The total area of the prism is [tex]SA=(\frac{9\sqrt{3}}{2}+54)\ in^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of the triangular prism of the figure is equal to
[tex]SA=2B+PL[/tex]
where
B is the area of the triangular face
P is the perimeter of the triangular face
L is the length of the prism
Find the area of the base B
The base is an equilateral triangle
so
Applying the law of sines the area is equal to
[tex]B=\frac{1}{2}(3)^{2}sin(60\°)[/tex]
[tex]B=\frac{9\sqrt{3}}{4}\ in^{2}[/tex]
Find the perimeter P of the triangular face
[tex]P=(3+3+3)=9\ in[/tex]
we have
[tex]L=6\ in[/tex]
substitute
[tex]SA=2(\frac{9\sqrt{3}}{4})+(9)(6)[/tex]
[tex]SA=(\frac{9\sqrt{3}}{2}+54)\ in^{2}[/tex]

Answers
Answer:
89.0°
Step-by-step explanation:
The segment from the centre of the circle to the chord is a perpendicular bisector, hence
third side of right triangle = 12.7 ÷ 2 = 6.35
The angle subtended at the centre by arc CD is twice the angle subtended by the right triangle at the centre
The triangle from the centre to C is congruent to the triangle from the centre to D
Calculate the angle (Θ ) in the right triangle using the sine ratio
sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{6.35}{9.06}[/tex]
Θ = [tex]sin^{-1}[/tex] ( [tex]\frac{6.35}{9.06}[/tex] ) ≈ 44.5°
Hence
measure of CD = 2 × Θ = 2 × 44.5 = 89.0°
the volume of rectangular prism that measures 7 meters long, 9 meters wide, and 6 meters high is 378m^3
True or False
Answers
Answer:
Step-by-step explanation:
True
7 X 9 X 6 = 378
Answer:
First option: True.
Step-by-step explanation:
To know if the volume of this rectangular prism is 378 m³, you need to use the formula for calculate the volume of a rectangular prism:
[tex]V=lwh[/tex]
Where "l" is the lenght, "w" is the width and "h" is the height.
You know that that this rectangular prism measures 7 meters long, 9 meters wide, and 6 meters high, then you can substitute these values into the formula.
Therefore, the volume of the rectangular prism is:
[tex]V=(7m)(9m)(6m)\\V=378m^3[/tex]
Then the answer is: True.

Which sequence is generated by the function f(n 1) = f(n) – 2 for f(1) = 10? (a) –10, –12, –14, –16, –18, ... (b) –2, 8, 18, 28, 38, ... (c) 8, 18, 28, 38, 48, ... (d) 10, 8, 6, 4, 2, ...
Answers
Answer:
d
Step-by-step explanation:
Given
f(n + 1) = f(n) - 2 with f(1) = 10
To generate the sequence substitute values for n into the recursive formula.
f(1) = 10
f(2) = f(1) - 2 = 10 - 2 = 8
f(3) = f(2) - 2 = 8 - 2 = 6
f(4) = f(3) - 2 = 6 - 2 = 4
f(5) = f(4) - 2 = 4 - 2 = 2
The first 5 terms are 10, 8, 6, 4, 2

If a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line in slope intercept form
Answers
Answer:
y=-2x+3
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope, b is the y-intercept, and y and x are their respective coordinates.
The questions gives us a coordinate pair and a slope so all we need to find is the y-intercept to find the equation.
Begin by plugging in what we know.
(3) = (-2)(0) + b
3 = 0 + b
3 = b
Plug in the y-intercept (b) and slope (m)
y=-2x+3
