Answer:

(x)^2+ (y+2)^2 = 49

Step-by-step explanation:

The standard form of a circle is

(x-h)^2+ (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-0)^2+ (y--2)^2 = 7^2

(x)^2+ (y+2)^2 = 49

One week a business sold 40 shirts. White ones cost $4.95, and the printed ones cost 7.95. In al $282 worth of shirts were sold.

Tanya [424]

Answer:

12 white 28 printed

Step-by-step explanation:

x = white y = printed

x + y = 40————(1)

4.95x + 7.95y = 282————(2)

Solve for x using 1st equation

x = 40 - y Plug in for x using 2nd equation

4.95(40 - y) + 7.95y = 282 Solve for y

198 - 4.95y + 7.95y = 282

3y = 84

y = 28 Plug in for y using 1st equation

x + (28) = 40 Solve for x

x = 12

A hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. They sell 11 boxes that have 6 paintbrushes

grin007 [14]

Answer:

Step-by-step explanation:

The hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. This means that the total number of paintbrushes that was ordered is

12 × 9 = 108

Therefore, the total number of paintbrushes that the store has would be

200 + 108 = 308

They sell 11 boxes that have 6 paintbrushes each. This means that the total number of paintbrushes that they sold is

11 × 6 = 66

Therefore, the number of paintbrushes left would be

308 - 66 = 242

The manager's estimate is reasonable. They ordered about 120 paintbrushes and sold about 60 of them so they should have about 60 more paintbrushes than they started with.
