Answer:
286.94 cm
Step-by-step explanation:
Data:
Area = 8,607
b1 = 105
b2 = 123
Area = 1/2 * (b1 + b2) * h
h = 2 * Area/b1 + b2
h = 2 * 8,607/105 + 123
h = 286.94 cm
I'm not sure if it's right but that's what my calculator gave me.
I know you already got this answered, but I need points. Can I get brainliest?
Answer:
E,A,C,B,D
Step-by-step explanation:
make the denominator 12 and multiply e.g.3
<u>Answer</u>
320 cm³
<u>Explanation</u>
Firstly, find the constant of proportionality.
V ∝ 1/p
V = k/p Where V= volume, k = constant and p = pressure of the gas.
1600 = k/4
k = 1600 × 4
= 6,400
The equation will be,
V = 6,400/p
For p =20 Kg/cm²,
V = 6,400/20
= 320 cm³
I think that it's B, y = -x - 7 because first you'd subtract y to get it on the other side then add x and then you'd need to make the y positive so you would divide x + 7 by -1 and that would make it y = -x - 7.
