First answer 14^5. Second answer 42^5
First, divide the shape into two shapes: the trapezoid on the very top and the large rectangle that makes up most of the bottom. Then, find the area of each, and add them together for the total area.
<u>Trapezoid:</u>
A=0.5(b1+b2)h
A=0.5(7+14)5
A=0.5(21)5
A=52.5
<u>Rectangle:</u>
A=lw
A=12(14)
A=168
52.5+168=220.5
The area is 220.5 square feet.
Hope this helps!!
The first answer would be A because the volume is l*w*h so you would multiply 24 by 10 by 12 which gives you 2880 ft^3
I don't know how to do the second question. I am sorry!
Answer:
A= (2,4)
B= Infinitly Many Solutions
Step-by-step explanation:
Answer:
i) = 23 °C
ii) = 4.4° C
Step-by-step explanation:
i) The temperature on the surface of the planet.
At the surface of the planet the height is Zero
Therefore, X = 0
Thus; using the equation, the temperature, y will be;
y = 23 - 5x
y = 23 - 5(0)
<u> = 23 °C</u>
ii) the temperature change for every kilometer from the surface,
From the equation;
y = 23 - 5x
we take, y to be 1
Therefore;
1 = 23 -5x , subtracting 23 on both sides we get
-22 = -5x
x = -22/-5
<u> = 4.4° C</u>
