Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
Answer:
a rational number
Step-by-step explanation:
3.4 is a terminating decimal. That means that after the 4 in 3.4 there are no other numbers (the number "ends" after the 4) Also, 3.4 can be written as a RATIO of two numbers (looks like a fraction)
3.4 = 3 4/10 = 3 2/5
= 15/5 + 2/5
= 17/5
If you put 17÷5 in a calculator it would say 3.4
3.4 = 17/5
3.4 is a rational number.
Answer:
<h2><u>48√2</u> is the right answer.</h2>
It takes 9 seconds to hit the ground.
Setting the equation equal to 0, we have:
0 = 144 + 128t - 16t²
Factoring out the GCF, we have
0 = 16(9 + 8t - t²)
Factoring out -1, we have:
0 = -16(-9 - 8t + t²)
In standard form, this is
-16(t² - 8t - 9) = 0
This is easily factorable; -9(1) = -9 and -9+1 = -8:
-16(t-9)(t+1) = 0
Using the zero product property, we know either t-9=0 or t+1=0; therefore t=9 or t=-1. Since negative time makes no sense, t=9.
X = 5 ... y = 12
x = ? ... y = 30
If you would like to know the value of x when y = 30, you can calculate this using the following steps:
5 * 30 = x * 12
x * 12 =150 /12
x = 150 / 12
x = 12.5
The result is 12.5.
