Answer:
13 sq cm.
Step-by-step explanation:
To find the area of this irregular figure, we will need to find the areas of a rectangle and triangle within this figure.
To find the area of the rectangle, we can simply do:
1 × 4= 4 sq cm.
Now, this is where it gets a little trickier. To find the area of the triangle, we will first need to determine the base and height.
We can see from the diagram that to find the base, we need to subtract:
7-4= 3 cm. This is the base of ONLY the triangle.
To find the height, we will need to do:
5+1= 6 cm. This is the total height of the entirety of the triangle.
We can now use the Triangle Area formula: [tex]\frac{1}{2}[/tex](bh), to calculate the area of the triangle.
[tex]\frac{1}{2}[/tex] (6*3)= 9 sq cm.
Finally, add the areas of the rectangle and triangle together, giving you:
9+4= 13 sq cm.
LaTasha was presented with the following data set and argued that there was no correlation between x and y. Is LaTasha correct? Use the regression equation to explain your reasoning.
Answer:
LaTasha is correct. There is no correlation between x and y. The slope of the line of best fit is zero, which shows that there is no negative or positive correlation.
No, LaTasha is not correct. To determine whether there is a correlation between x and y, we need to use the regression equation and calculate the correlation coefficient.
Explanation:No, LaTasha is not correct. To determine whether there is a correlation between x and y, we need to use the regression equation. If the regression equation is significant and the correlation coefficient is significantly different from zero, then there is a linear relationship between x and y. If the correlation coefficient is not significantly different from zero, then there is no significant linear relationship. In this case, we need to calculate the correlation coefficient and see if it is significant.
To calculate the correlation coefficient, we use the formula r = √(SSR / SST), where SSR is the sum of squared residuals and SST is the total sum of squares. If the correlation coefficient is significantly different from zero, then there is a linear relationship between x and y.
In conclusion, we cannot determine if there is a linear correlation between x and y without calculating the correlation coefficient.

What is 5 to the 3rd power in standard form
Answer:
125
Step-by-step explanation:
5x5=25 25x5=125
5 to the 3rd power (5^3) in standard form is 1.25 * 10^2.
To express 5 to the 3rd power (5^3) in standard form, we'll calculate the result first and then represent it in standard form.
5^3 means multiplying 5 by itself three times:
5^3 = 5 * 5 * 5 = 125.
Now, to express 125 in standard form, we'll use the convention where a number is written as a product of a number between 1 and 10 and a power of 10. This form is used to make large or small numbers more manageable
To do this, we'll write 125 as 1.25 multiplied by a power of 10. Since 125 is equal to 1.25 multiplied by 100 (10^2), we can express it in standard form as:
125 = 1.25 * 10^2.
5 to the 3rd power (5^3) in standard form is 1.25 * 10^2.
In standard form, numbers are expressed as A × 10^n, where A is a number between 1 and 10, and n is an integer representing the power of 10 by which A is multiplied to form the number. In this case, A is 1.25, and n is 2, making it 1.25 × 10^2.
This form simplifies large numbers and is commonly used in mathematics and science for ease of representation.

Answer:
the answer to your question will be n = 7
Step-by-step explanation:
as much as I would like to, I'm really not that great at explaining things
The value of x from the given equation is 7.
The given equation is 6(n-3)-2n=10.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 6(n-3)-2n=10

Angle DXC and ________ are complementary angle?
Angle DXC and BXC are complementary angle.
Step-by-step explanation:
∠DXC complements with ∠BXC
Complementary angle means the sum of 2 angles that have a vein or form a right angle, which is 90°.
If we add ∠DXC with ∠BXC, it will form a right angle, 90°.
Hope it helpful and useful :)
We want to find the complementary angle to DXC.
We will see that the complementary angle is CXB
Let's start by defining what complementary angles are.
Two angles a and b are complementary if:
a + b = 90°.
This means that we must find another angle such that when we add it to DXC we get a right angle.
Let's look at the diagram.
We can see that we have the line AD, and there is a segment XB, such that the angle AXB is a right angle.
Then the angle DXB is also a right angle.
Now, you can see that the angle DXB is equivalent to DXC + CXB
Then we can see that the complementary angle to DXC is CXB.

High Flying Airlines charges $20 to check a piece of luggage up to 40 pounds. Each additional pound over 40
pounds costs $0.25. The maximum weight for a piece of checked luggage is 80 pounds. Write a function to
represent the situation.
To represent the situation, we can define a function called calculateLuggageCost that takes the weight of the luggage as an input and calculates the cost based on the given pricing structure. The function checks if the weight is less than or equal to 40 pounds and returns $20 in that case. If the weight is between 40 and 80 pounds, it calculates the additional cost by multiplying the excess weight (weight - 40) by $0.25 and adds it to the base cost of $20. If the weight exceeds 80 pounds, it returns a message indicating that the maximum weight limit has been exceeded.
Explanation:To represent the situation, we can define a function that takes the weight of the luggage as an input and calculates the cost based on the given pricing structure. Let's call this function calculate Luggage Cost. Here's how we can define it:

Volume =
The volume of the cylinder is approximately 21727.938in^3.
The volume (V) of a cylinder is calculated using the formula:
V=πr^2 h
where:
π (pi) is a mathematical constant approximately equal to 3.14159,
r is the radius of the cylinder,
h is the height of the cylinder.
Given that the radius (r) is 16 inches and the height (h) is 27 inches, you can substitute these values into the formula:
V=π×(16in)^2 ×27in
Now, let's calculate the volume. Remember to use the value π as approximately 3.14159:
V≈3.14159×256×27
V≈3.14159×6912
V≈21727.938in^3
So, the volume of the cylinder is approximately 21727.938in^3.

Determine the angles A and B given the following information:
a=15
b=22
Answer:
B ≈ 55. 71°
A = 34.29°
Step-by-step explanation:
The picture demonstrate on how you could solve the angles of A and B in a triangle with a given sides a and b. Angle C is a 90° .That makes the triangle a right angle triangle.
Let us find angle B
using SOHCAHTOA principle
tan B = opposite.adjacent
tan B = b/a
tan B = 22/15
tan B = 1.46666666667
B = tan⁻¹ 1.46666666667
B = 55.7131230228 °
B ≈ 55. 71°
Let us find angle A
The sum of angle in a triangle = 180° Therefore, the angle A can be solved when you subtract angle C and B from 180°.
angle A = 180° - 90° - 55.71°
angle A = 34.29°
At the gym, Ava swims every 10 days, runs every 4 days and cycles every 5 days. If she did all three activities today, in how many days will she do all three activities again on the same day?
Answer: After 20 days
Step-by-step explanation: you have to find the greatest common multiple so that the number is a multiple for each of them
since 10 is multiple of 5 you have to find the lcm of 10 and 4 or 5 and 4 which is still 20
so just multiply them and if she swims and does cycles every 10 days then you know that if she is swimming she is cycling, but if she is cycling she might not be swimming. So if running is 4 days then just multiply 4*5 = 20

Anthony rode this bike from point A to point B using Cherry Street. How much FURTHER would his trip have been if he took Orange Drive and Peach Avenue instead?
a.36 yards
b.113 yards
c.28 yards
d.198 yards
Answer: c.28 yards
Step-by-step explanation:
Hi, Since the triangle is a right triangle we have to apply the Pythagorean theorem to find the lenght of Orange Dr street.
c2 = a2+b2
Where c is the hypotenuse (the longest side) and a and b are the other sides of the triangle.
Replacing with the values given
85^2 = 77^2 + b^2
7225 = 5929 +b^2
7225-5929 = b^2
1296 = b^2
√1296 = b
36 = b ( orange Dr length)
Adding the lengths of orange and Peach ave .
36+77 = 113 yards
Subtracting the length of cherry st.(85)
113 -85 = 28 yards
His trip would have been 28 yards further
What is the domain of y = log Subscript 4 Baseline (x + 3)?
all real numbers less than –3
all real numbers greater than –3
all real numbers less than 3
all real numbers greater than 3
Answer:
All real numbers greater than -3
Step-by-step explanation:
The domain of a log is the baseline is greater than 0.
Set x + 3 greater than zero and solve
x + 3 > 0
x > -3
The domain of the function y = log4(x + 3) is all real numbers greater than -3, as the argument of the logarithm must be positive.
The domain of the function y = log4(x + 3) is determined by the values of x for which the logarithmic expression is defined. Since the logarithm of a number is only defined for positive arguments, we need x + 3 to be greater than zero. Therefore, the domain is all real numbers greater than -3.
What this means is x must be any number such that when you add 3 to it, the result is a positive number. A simple inequality expresses this: x + 3 > 0, which simplifies to x > -3. Hence, the correct domain is all real numbers greater than -3.

The area of a bedroom floor is the width multiplied by the length. We know that the length's is [tex]10\frac{2}{3}[/tex] feet and the width is [tex]8\frac{3}{4}[/tex] feet. We just multiply the 2 fractions to find the area of her bedroom floor in feet squared
[tex]10\frac{2}{3} * 8\frac{3}{4}[/tex]
→ There area various methods but I am going to use the improper fraction method. First convert the fractions into improper fractions
[tex]\frac{32}{3} *\frac{35}{4}[/tex]
→ We can cancel out 4 and 32 with 1 and 8
[tex]\frac{8}{3} *\frac{35}{1}[/tex]
→ Multiply like normal fractions
[tex]\frac{280}{3}[/tex]
→ Convert into mixed fraction
[tex]93\frac{1}{3}[/tex]
Final answer:
The area of Kara's bedroom floor is 93 1/3 square feet, which is calculated by converting the given dimensions into improper fractions, multiplying them, and then simplifying.
Explanation:
The area of Kara's bedroom floor is calculated by multiplying the room's length by its width. The dimensions of the room are given as 8 3/4 feet by 10 2/3 feet. We first convert these mixed numbers into improper fractions: 8 3/4 becomes 35/4 and 10 2/3 becomes 32/3. To find the area, we multiply these two fractions together:
Area = (35/4) × (32/3) feet2
Now, we find the product of the two fractions:
Area = (35 × 32) / (4 × 3) square feet
Area = 1120 / 12 square feet
Area = 93 1/3 square feet
Therefore, the area of the bedroom floor is 93 1/3 square feet. When purchasing carpet, Kara would need to round up to ensure she has enough carpet to cover the entire floor, which is typically sold by the whole square foot.
