To find the slope of line v, divide the change in y-values by the change in x-values:
17 - 10 / 1 - 9
7 / - 8
Slope of line v = -7/8
Now, slopes of perpendicular lines are negative reciprocals of each other, therefore:
The slope of line w = 8/7
Hope this helps.
Answer:
=240,000ml
Step-by-step explanation:
v = l*w*h
v = 100*40*60
v = 240,000 cm³
if 1cm³ = 1 ml
240000cm³ = x
=240,000ml

Answer:
Step-by-step explanation:
The surface area of a cylinder is 2pi *rh + 2pir^2, where r and h are radius and height, respectively. (If you want me to explain this, comment down below). Anyways, we can simply plug in 11 and 8 in the formula, so 2* 8*11*pi + 2* pi * 8^2=304pi. Thus, we do 304 * 3.14=954.56.
