Step-by-step explanation:
-2.25 x 3 = 6.75
the temperature decreased by 6.75 after 3 hours
SA formula: Ph + 2B
B is the trapezoid side.
using the formula:
(3+4+5+6)*5 + 2(16) = 126 cm^2
Answer:
Step-by-step explanation:
We were given that; the formula for the surface area, A, of a prism is given by
where is the length of the prism, w is the width, and h is the height.
We want to solve this formula for l,
Group the l terms;
Factor l on the right;
Divide both sides by 2w +2h
Therefore:
The answer is D
This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.
The proportion is as follows:
50/5 == 500/x
x is equivalent to the amount of money he has saved
You can cross multiply to get the following equation:
50x == 2500
To isolate x, you must divide both sides by 50, giving you an answer of:
x = 50
This is the same as option D
