Answer:
175
Step-by-step explanation:
It is much easier if you use the unit rate, so we'll convert the first senta\ence into a ratio. 2 cubic feet:90lb. you need to get 1 cubic foot, so divide both sides my 2, 1 cubic foot:35 pounds. now, to get five cubic pounds(See where this is going?) you multiply both sides by 5. 5 cubic feet:175lb
(these idoits make you go back and forth in solving problems)
Answer:
700.39cm
Step-by-step explanation:
For a horizontal distance of 30cm, the drop is 1cm, now we need to get the drop for horizontal distance of 700 cm to maintain the same slope
Using the concept of cross multiplication
30cm=1 cm drop
700 cm=x
30x=700
X=700/30=70/3=23 ⅓
Utilizing pythagoras theorem, the length of pipe will be
L=√(23⅓)²+700²
L=700.38878092417 cm
Rounded off, the length is approximately 700.39 cm
Hopefully this helps, and sorry I didn't do 8 I'm limited on time

Answer:
x 2 + 5 x + 6
Step-by-step explanation:
y = m x + c
y- intercept
x = 0
y = (-2) (0) + 3
=3
(x =0, y = 3)
<h3>slope -2 </h3><h3>y = -1 x + 3</h3>
