1 answer:

7 0

When finding the -3√3 curved line, we look at the tangent of the angle. Since it has a negative beginning, we subtract the angle of the tangent, 30 degrees, from 180 degrees. Thus the angle

It has 90+60=150 degrees

C=πd.
C is the Circumference.
d is diameter.
π is the ratio for Pi,

In this case we will use:
3.14 instead of π
d = 26.5 mm

Plug in the known values. 
C=(3.14)(26.5) = 83.21 mm

Ty is at Home Depot and must decide whether to buy paint in 10 individual quart cans or to buy it in both gallon and quart cans.

Ulleksa [173]

Find the cost of 4 quarts:

$ 6.99 [Cost of 1 quart] x 4 [Number of quarts] = $27.96 [Cost of 4 quarts]

Find the difference in price between 1 gallon and 4 quarts.

$ 27.96 [Cost of 4 quarts] - 20.99 [Cost of 1 gallon] = $ 6.97 [Difference]

One gallon of paint is less expensive than 4 quarts. The amount you save, $6.97, is just about the price of 1 quart of paint. When you buy the gallon, you get nearly 1 quart free.

Find out how many gallons to buy. Divide the total number of quarts needed by 4. This answer will tell Michael the number of gallons and quarts he needs.

10 ÷4 = 2 Gallons, 2 quarts

Two gallons and 2 quarts are equal to 10 quarts.

Find the cost.

$ 20.99 [Cost per gallon] x 2 = $41.98 [Cost of 2 gallons]

$ 6.99 [Cost per quart] x 2 = $13.98 [Cost of 2 quarts]

$ 41.98 [Cost of 2 gallons] + 1 3.98 [Cost of 2 quarts] = $ 55.96 [Total cost]

10 individual quarts cost $69.90 vs $55.96

So answer is C/2 gallons 2 quarts
