I gave you the answer to number 11 on your other post, and for 12, this is how you do it...
10 ft 6 in is 10.5 ft first off.
Set up for cross multiplication... use 7^2 and 10.5^2 because it's area.
3/7^2 x y/10.5^2... 49y=330.75... y=6.75
So, 6.75 pints of stain are required to paint a deck 10 ft 6 in x 10 ft 6 in, if 3 pints is required for 7 ft x 7ft, and the amount of stain proportional to the area of the deck

Step-by-step explanation:

4^5 (-2)^9/4^8 (-2)^3

= 4^(5 - 8) (-2^(9 - 3))

= 4^-3 (-2^6)

= (-2)^6/4^3

1). (-2)^a/4^b

a = 6, b = 3

2). c/d

c = -2, d = 4

The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20

Pepsi [2]

Answer: They can order from 0 to 449 bars, but no more.

Step-by-step explanation:

Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.

The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.

$0.40x+20$
