To solve this problem we can use the rule of 3 and solve for x. Let's equate it as the following:

28.52/x=36.8/100

Why did I represent it like that?
In the first numerator we have the known quantity (28.52). In the second numerator we'll need the percentage that 28.52 represents (because the second fraction will represent percents). This will be 36.8%
The first denominator is x (the number we want to figure out). That number represents 100%. Hence the 100 as the second denominator.

To solve for x we need to do the following:
x=(28.52*100)/ 36.8
x=2852/36.8
x=77.5

Answer: 28.52 is 36.8% of 77.5

The correct answer is: 36.8% of 77.5 is 28.52

Explanation:

Simply translate "36.8% of what number is 28.52" mathematically as follows:

36.8% * x = 28.52 --- (1)

x represents "what number" in the sentence

= represents "is."

Now, we can write 36.8% as \frac{36.8}{100} when we remove the % symbol. Rewrite equation (1) as follows:

\frac{36.8}{100} * x = 28.52

Now evaluate for x:

\frac{36.8}{100} * x = 28.52 \\ x = \frac{100}{36.8}*28.52 =  77.5 \\

Hence the correct answer is 36.8% of 77.5 is 28.52.

Which expression can be used to find the surface area of the following square pyramid
mariarad [96]

Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?
ale4655 [162]

Answer:

(x + 4)^2 + (y – 9)^2 = 25

Step-by-step explanation:

The standard form for a circle is

(x - h)^{2} + (y - k)^{2}  = r^{2}     where (h, k) is the center and r is the radius

In your case, h = -4 and k = 9 and r = 5

So, (x + 4)^2 + (y – 9)^2 = 25
