Answer:
C. xy²
Step-by-step explanation:
You have to add the exponents:
(xy) exponent is 1
(x) exponent is 1
Combine the (x):
xy²
they offer a lot of discounts prety much
First we need to calculate the volume which is Base*depth or length*width*depth
first we have to change all the units so they are the same, 3 inches in this case will equal 1/4feet
multiply all the numbers together
35ft*12ft*1/4foot= 105 cubic feet
however the problem says the cost per cubic *yards*
so take the 105 cubic feet and divide by 3 (3 feet to a yard)
105/3 = 35 cubic yards
the cost of 35 cubic yards of concrete =
35*125= $4375
Answer:
x = 175 km
Step-by-step explanation:
We can use ratios to solve this problem. Put the map distance over the real life distance.
1 cm 7 cm
-------- = ---------
25 km x km
Using cross products.
1 * x = 7 * 25
x = 175 km
3x + 8 = -22
-8 -8
3x = -30
x = -30/3 = -10
Correct choice is 1).
