Answer:
a ) 400 percent
b ) n = 25
c) n= 36
Step-by-step explanation:
Is means equals, of means multiply and percents need to be changed to decimals.
a) 120 is what percentage of 30
120 = P * 30
Divide each side by 30
120/30 =P* 30/30
4 = P
Multiply by 100 to give the percentage
4 * 100
400 percent
b) 30 is 120% of what number
30 = 1.2 * n
Divide each side by 1.2
30/1.2 = 1.2n/1.2
25 = n
c) what number is 30%of 120
n = .3 * 120
n =36
Answer:
D. 6 feet
Step-by-step explanation:
The volume of a rectangular prism can be found by using <em>L </em>* <em>W </em>* <em>H</em>, or <em>B </em>* <em>H</em>
-> The length (<em>L</em>) times the width (<em>W</em>) is equal to the base (<em>B</em>)
<em>V </em>= <em>B </em>* <em>H</em>
528 = 88<em>H</em>
6 = <em>H</em>
Answer:
4
Step-by-step explanation:
I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.
