Answer:
a=1.5b
Step-by-step explanation:
Add 2b on both sides to get 7a=5a+3b
Subtract 5a
2a=3b
divide by 2
a=1.5b
Answer:
Step-by-step explanation:
<u>Volume of the pyramid:</u>
<u>Find base area:</u>
- B = 1/2(20 + 30)*20 = 500 cm²
<u>Substitute value of the volume and find the height of the pyramid:</u>
- 4500 = 1/3*500*h
- h = 4500*3/500
- h = 27 cm
<u>The boxes with h > 27 can fit the pyramid: </u>
Yes, I'm getting C also!
Since it's asking for the left-endpoint Riemann Sum, you will only be using the top left point as the height for each of your four boxes, making -1, -2.5, -1.5, and -0.5 your heights. The bases are all the same length of 2. You don't include f(8) because you're not using right-endpoints, and that would also add another 5th box that isn't included in the 0 to 8 range.
Answer:
x = 2/3
Step-by-step explanation:
-3x + 4 = 2
-3x = -2
x = 2/3
y = 2
(plug it into original equation)
(2/3. 2)
Answer:
non-included
Step-by-step explanation:
A non included side of a polygon shares a side with only one angle of a pair of angles.
