Answer:

Answer:

85t

If a logo of 6 ft and he needs a quart of paint for every 22 square ft how many quarte will he need for the whole logo
bulgar [2K]

Complete Question

If a logo has dimensions of 6 ft and 11ft, he needs a quart of paint for every 22 square ft. How many quarts will he need for the whole logo?

Answer:

3 quarts of paint

Step-by-step explanation:

The Logo is rectangular in shape, hence:

The area of a rectangle = Length × Width

The logo has dimensions of 6 ft and 11ft.

Area of the Logo = 6ft × 11ft = 66ft²

He needs a quart of paint for every 22 square ft

Hence:

22 ft² = 1 quart of paint

66ft² = x

Cross Multiply

22 ft² × x = 66 ft² × 1 quart

x = 66 ft² × 1 quart/22 ft²

x = 3 quarts of paint

Therefore, he will need 3 quarts of paint for the whole logo.

Write the equation for the quadratic function in the graph
Hoochie [10]

Answer:

{x}^{2}  - 16 = 0 \: is \: the \: equation

Step-by-step explanation:

x =  - 4 \\ or \: x = 4

(x + 4) = 0 \: or \: (x - 4) = 0 \\ (x + 4)(x - 4) = 0 \\ open \: the \: bracket

x(x - 4) + 4(x - 4) = 0

{x}^{2}  - 4x + 4x - 16 = 0 \\  {x}^{2}  - 16 = 0
