Answer:
h = 13 units²
Step-by-step explanation:
The way to find the area of a parallelogram is to multiply the length of one side (21) and multiply it by the height:
A = l*h
We know the area and the length:
273 = 21*h
Now we solve for height.
273/21 = (21*h)/21
273/21 = h
273/21 = 13
h = 13 units²
Answer:
y = -3, -4
Step-by-step explanation:
Formula is (b/2)^2
So...
(y+7/2)^2 - 1/4 = 0
Add 1/4 to each side
(y+7/2)^2 = 1/4
Square root...
y+7/2 = +-1/2
Add
y = -3, -4
Answer:
x = 29°
Step-by-step explanation:
Answer:
8 cm
Step-by-step explanation:
volume of a cylinder is v=pi x r^2 x h
substitute in what we know
3785= pi x r^2 x 19
3785=59.69 x r^2
subtract 59.69 from both sides
3725.31=r^2
square root of 3725.31
61
square root of 61
= about 8
Divide each one out to see which is cheaper. 4.39/12 = .37 cents per pint while 2.89/8 = .36 cents per pint. These are cost per unit problems.The second choice is the cheaper of 2 by a cent.
