A cone-shaped hat is shown:
A cone is shown with slant height 18 cm and radius 5.7 cm. The unknown height is labeled with a question mark, and the line joining the tip of the cone to the base is perpendicular to the base.
What is the approximate height of the hat?
3.51 centimeters, because height = Square root of the difference of 18 and 5.7
17.07 centimeters, because height = Square root of the difference of the squares of 18 and 5.7
18.88 centimeters, because height = Square root of the sum of the squares of 18 and 5.7
4.87 centimeters, because height = Square root of the sum of 18 and 5.7
Answers
h^2=x^2+y^2
18^2=5.7^2+y^2
y^2=18^2-5.7^2
y^2=291.51
y=√291.51
y≈17.07
It's the second explanation down...
Answer:
B. 17.07 centimeters, because height = Square root of the difference of the squares of 18 and 5.7.
Step-by-step explanation:
The formula of height (h) of a cone is: [tex]h=\sqrt{l^2-r^2}[/tex], where,
[tex]l[/tex] = Slant height of cone,
[tex]r[/tex] = Radius of cone.
Upon substituting slant height = 18 cm and radius = 5.7 cm, we will get,
[tex]h=\sqrt{(18)^2-(5.7)^2}[/tex]
[tex]h=\sqrt{324-32.49}[/tex]
[tex]h=\sqrt{291.51}[/tex]
[tex]h=17.0736639301586348\approx 17.07[/tex]
Therefore, the height of cone is 17.07 cm and option B is the correct choice.

True or false X=4 for both 1. 3x+10-(5+3)=14 2. 3x+10(3x-2)=60
Answers
For the first equation,
3x+10-(5+3)=14
Every time we see an X, we need to place a 4 in its place.
3(4)+10-(5+3)=14
Using the order of operations, PEMDAS, we start to solve the equation.
3(4)+10-(5+3)=14
12 + 10 - (5+3) = 14
12 + 10 - (8) = 14
12 + 10 - 8 = 14
22 - 8 = 14
14 = 14
TRUE.
For the first equation, x does indeed equal 4.
However, we still need to see if x equals 4 for BOTH of the equations.
3x+10(3x-2)=60
3(4) + 10(3(4)-2) = 60
12 + 100 = 60
112 = 60
This isn't true.
To conclude, the answer is false. X doesn't equal 4 for both of the equations provided.

a rectangular school gym has a length of x+24 and a width of x-10. Which measure does (x+24)(x-10) represent?
Answers
l x w = area
(x+24)(x-10) means (x+24) *(x-10) which is to calculate the area
Answer: The measure (x+24)(x-10) represents the AREA of the rectangular school gym.
Step-by-step explanation: Given that a rectangular school gym has a length of (x+24) and a width of (x-10).
We are to find the measure that (x+24)(x-10) represent.
The expression (x+24)(x-10) is the product of the length and breadth of the given rectangular school gym.
Also, we know that
the product of the length and breadth of any rectangle is equal to the area of that rectangle.
Therefore, the measure (x+24)(x-10) represents the AREA of the rectangular school gym.
Tuna provides 30 calories per ounce . On a graph representing the relationship between the number of ounces of tuna a person consumes and the number of calories the tuna provides which quantity should be graphed on the x-axis
Answers
Answer:
Ounces of tuna will go on the x axis and calories on the y axis. This is because the relationship between the number of ounces a person eats and the calories he consumes then is a positive correlation (a line with a positive slope which goes from lower left to upper right) with x being the independent variable. As x increases, y increases. In other words you can ONLY change the amount of calories you consume WHEN you change the amount of ounces you eat. You can't change the number of calories independent of the number of ounces. The independent variable goes along the x axis, cuz the x variable always represents the independent variable.

The odds that you will pick a heart from a standard deck of 52 cards is 13:39. TRUE or FALSE
Answers
the odds of picking a heart is 13:39.
the statement is TRUE.
To determine whether the statement is true or false, we need to calculate the odds of picking a heart from a standard deck of 52 cards and compare it to the given odds of 13:39.
Step 1: Calculate the number of hearts in a standard deck.
A standard deck of 52 cards contains 13 hearts.
Step 2: Calculate the total number of cards in the deck.
A standard deck of 52 cards contains 52 cards.
Step 3: Calculate the odds of picking a heart.
The odds of picking a heart can be expressed as the ratio of the number of favorable outcomes (hearts) to the number of unfavorable outcomes (non-hearts).
Number of hearts: 13
Number of non-hearts: 52 - 13 = 39
So, the odds of picking a heart is 13:39.
Now, let's compare the calculated odds (13:39) with the given odds (13:39).
Since the calculated odds match the given odds, the statement is TRUE.
A rocket is launched into the air. The projectile motion of the rocket can be modeled using h(t) = 112t –16t2, where t is the time since launch in seconds and h(t) is the height of the rocket at time t. When will the rocket be 196 feet in the air?
A.) after 2.0 seconds
B.) after 3.5 seconds
C.) after 4.5 seconds
D.) after 7.0 seconds
*The answer is B, after 3.5 seconds. If anyone wants to properly explain how this is the correct answer, I will give you brainliest.*
Answers
.
h ( t ) = 112 t - 16 t²
When the rocket is 196 feet in the air:
196 = 112 t - 16 t²
16 t² - 112 t + 196 = 0
divide everything by 4 ( just makes numbers smaller and easier to work with)
4 t² - 28 t + 49 = 0
Now factor the equation:
( 2 t - 7 )² = 0
2 t - 7 = 0
2 t = 7
t = 7 : 2
t =
3.5 s
The rocket will be 196 feet in the air after 3.5 seconds.
Why is sin(20) = sin(160) = -sin(200) = -sin(340)?
Answers
Answer:
see.
Step-by-step explanation:
The value of sin is the same at the same distance from the cuadrant limit of the point. For the case of 20°, we have that the sin is the same in the following case:
As 20 is positive we use the limit cuadrant at 90°. The distance of 20 to 90 is 70. So, sin(20)=sin(90+70)=sin(160).
Also we have that sin(x) is a odd function, so sin(-x)=-sin(x), so
sin(-20°)= -sin(20°)
-sin(-20°)=sin(20°)
-sin(340°)=sin(20°).
and,
sin(-160°)=-sin(160°)
-sin(-160°)=sin(160°)
-sin(200°)=sin(160°)=sin(20°).

We can show that triangle abc is congruent to triangle a prime b prime c prime by translation of
Answers
Final answer:
To show congruence by translation, we need to show that corresponding sides and angles of the triangles are equal.
Explanation:
To show that triangle ABC is congruent to triangle A' B' C' by translation, we need to show that they have the same shape and size.
Translation is a transformation that moves every point of a figure the same distance in the same direction. Therefore, to show congruence by translation, we need to show that the corresponding sides and angles of the two triangles are equal.
For example, if we have AB || A'B' and AB = A'B', BC || B'C' and BC = B'C', and AC || A'C' and AC = A'C', then we can conclude that triangle ABC is congruent to triangle A' B' C' by translation.

(a) Is -e+f positive or negative. Explain how you know.
(b) Is e-f positive or negative? Explain how you know.
(c) Is f-e positive or negative. Explain how you know.
Answers
Given that e and f are real numbers where e > 0 and f < 0.
Since e > 0, this means that e is positive and -e is negative.
Also, since f < 0, this means that f is negative.
The sum of two negative numbers gives a negative number.
Therefore, -e + f is negative.
Part B:
Given that e and f are real numbers where e > 0 and f < 0.
Since e > 0, this means that e is positive.
Also, since f < 0, this means that f is negative and -f is positive.
Recall that e - f = e + (-f)
The sum of two positive numbers gives a positive number.
Therefore, e - f is positive.
Part C:
Given that e and f are real numbers where e > 0 and f < 0.
Since e > 0, this means that e is positive and -e is negative.
Also, since f < 0, this means that f is negative.
Recall that f - e = f + (-e)
The sum of two negative numbers gives a negative number.
Therefore, f - e is negative.

P(w/r) is the probability of picking a white rose at first picking and a red rose at second picking.
P(r/w) = [tex] \frac{11}{19} [/tex]×[tex] \frac{8}{18} [/tex] = [tex] \frac{88}{342} [/tex]
P(w/r) = [tex] \frac{8}{19} [/tex]×[tex] \frac{11}{18} [/tex]=[tex] \frac{88}{342} [/tex]
Notice that the second fraction is out of 18 because the second picking of rose will be out of 18 since the first rose is not replaced.
