Answer:
25%
Step-by-step explanation:
Given the following question:
What percent is 10 out of 40?
We use the formula to calculate percentages to find the answer.
[tex]\frac{p \times n}{100}[/tex]
[tex]\frac{25\times40}{100} =25\times40=1000\div100=10[/tex]
[tex]=10[/tex]
"25%" of 40 is equal to 10.
Hope this helps.

PLEASE HELP WILL GIVE BRAINLIEST AND 5.0 STAR RATING
Answer:
A. 3.14(6·4 +6²)
B. 188.4 square units
Step-by-step explanation:
Use the given expression to calculate surface area by substituting the numbers for the corresponding variables.
A.3.14(rs +r²) . . . . for r = 6 and s = 4
= 3.14(6·4 +6²)
__
B.Evaluating the above expression gives the surface area:
= 3.14(24 +36) = 3.14(60) = 188.4 . . . square units
Carlos mide 54 pulgadas de estatura ¿cual es la estatura de Carlos en pies?
Hola!
carlos mide 4.5 pies
Explicación:

A point at (-4,10) in the standard (x,y) coordinate
plane is translated right 10 coordinate units and down
4 coordinate units. What are the coordinates of the
point after the translation?
Translation involves changing the position of a point along the standard coordinate plane
The coordinate of the point after translation is (6,6)
How to translate the pointThe point is given as:
(-4,10)
When the point is translated 10 units right, the new coordinate becomes
(-4 + 10,10)
(6,10)
When the point is translated 4 units down, we have:
(6,10 - 4)
(6,6)
Hence, the coordinate of the point after translation is (6,6)

Answer:
3.25
Step-by-step explanation:
The mean is the average of the data. I remember this by thinking, 'the average person is mean.'To find the average, or mean, you would add all of the variables together and divide it by the number of variables. The number of variables here would be 10, because there are 10 litters.We would add the amount of kittens together and divide it by 10. This will get us 57 ÷ 10 = 5.7.To find the MAD, take the mean (5.7) and subtract each number from 5.7, then square it. For example... [tex][5.7 - 4]^{2}[/tex] would be solved by first subtracting what is in the parenthesis (PEMDAS) which gets us 1.7, then multiplying it by itself (1.7 • 1.7) which equals 2.89.Repeat this process for all data points.What I got for all of the data points [listed below]Once you get all of the data points, you add them all together. This gets you 32.5.Now you divide 32.5 by 10, (to find the average of it) which gets you 3.25.2.89.49.49.09.091.695.295.295.2910.89If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
What is the value of s?
Answer:
63
Step-by-step explanation:
(s-13) +s = s + 50
2s - 13 = s + 50
add 13 both sides, subtract the s from both sides
s = 63
Answer:
s = 63°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
s + 50 is an exterior angle of the triangle , then
s + 50 = s - 13 + s
s + 50 = 2s - 13 ( subtract s from both sides )
50 = s - 13 ( add 13 to both sides )
63 = s

In this module we reviewed finding the GCF of numbers and then finding the GCF of monomials. Below is an example of this work. Which statement best explains the similarities between the two methods?
Group of answer choices
When looking for common factors, we circle terms not in common between factors
When looking for common factors we are looking for the prime factors that are in common and then multiplying the prime factors together to get the GCF.
There are no similarities between finding the GCF of monomials and the GCF of numbers.
When looking for common factors, we use factor trees to determine the common factor and then dividing prime factors to get the GCF.
Answer:
2nd choice
When looking for common factors we are looking for the prime factors that are in common and then multiplying the prime factors together to get the GCF.

Two similar rectangles have a scale factor of 2. What is the ratio of their areas?
Answer:
Step-by-step explanation:
If the polygons are similar, this means that the ratio of their corresponding sides are equal. This ratio is what we commonly refer to as the scale factor. The ratio of the area of similar polygons is equal to the SQUARE of SCALE FACTOR. For this item since the scale factor is 2, the ratio of the areas is equal to 4.

Answer:
[tex]\huge\boxed{\bf\:(x + 2y)^{2} - 3}[/tex]
Step-by-step explanation:
[tex]x ^ { 2 } +4xy-3+4y ^ { 2 }[/tex]
Rearrange the terms.
[tex]x ^ { 2 } +4xy+4y ^ { 2 } - 3[/tex]
Here, x² + 4xy + 4y is in the form of the algebraic identity ⟶ x² + 2xy + y² = (x + y)². Then, here, x = 1 & y = 2y.
[tex](x + 2y)^{2} - 3[/tex]
Leave 3 as it is as 3 can't be further simplified. So, the final answer is:
[tex]\boxed{\bf\:(x + 2y)^{2} - 3}[/tex]
