Q18)
7/0.75 = 28/3
28/3(45) = 420 -> 420/60 = 7
Therefore the answer is B. 7 minutes.
Q20)
60.90/5 = 12.18
12.18(7) = 85.26
85.26+14.99 = 100.25
Therefore the answer is D. $100.25.

What is 10 of 25%......................................

tia_tia [17]

the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!

Which expression is equal to 4 (2+3) ? 1. 2+12 2. 4+5 3. 8+3 4. 8+12

allsm [11]

4. 8+12=20

4 (2+3)
First you add 2+3 and get 5
Next, since the 5 is now in the parentheses, it indicates that you have to multiply
Finally, 5 times 4=20

Trigonometry

[Right Triangles Only] Pythagorean Theorem:
$\displaystyle a^2 + b^2 = c^2$

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify given variables.

a = 30

b = 3

c = x

Step 2: Find x

Let's solve for the general equation that allows us to find the hypotenuse:

[Pythagorean Theorem] Square root both sides [Equality Property]:
$\displaystyle \begin{aligned}a^2 + b^2 = c^2 \rightarrow c = \sqrt{a^2 + b^2}\end{aligned}$

Now that we have the formula to solve for the hypotenuse, let's figure out what x is equal to:

[Equation] Substitute in variables:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2}\end{aligned}$
Evaluate:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2} \\& = \boxed{ \sqrt{909} } \\\end{aligned}$

∴ the hypotenuse length x is equal to √909 and the number under the square root, our answer, is equal to 909.
