Answer:
9 3/8 ounces of dog food
Step-by-step explanation:
1 cup = 1 7/8 ounces
1 7/8 + 1 7/8 = 2 14/8 = 3 6/8
3 6/8 + 1 7/8 = 4 13/8 = 5 5/8
5 5/8 + 1 7/8 = 6 12/8 = 7 4/8
7 4/8 + 1 7/8 = 8 11/8 = 9 3/8
28/2 or 28 x (1/2)
You can either divide $28 by 2 or multiply it by (1/2)
P = 2L + 2w
Subtract 2L
from each side: P - 2L = 2w
Divide each side
by 2 : (P - 2L) / 2 = w
You could also write it as (P/2 - L) = w
Both answers are the same.
Answer:
Step-by-step explanation:
If you subtract the extra 12 quarters from the total, you have $4.55 that can be made up of groups of 1 quarter and 1 dime. Since those groups are worth $0.35, there are $4.55/$0.35 = 13 of them.
There are 13 dimes and 13+12 = 25 quarters in the purse.
so hmmm which is it, the +/-? well, we know that <span>tan(θ) < 0, that means the tangent of the angle is negative, well, the tangent is opposite/adjacent, the only way that fraction can be negative, is that if either, no both, just either opposite or adjacent is negative.
well, we know the opposite is +1, so, the adjacent then has to be negative, so is -2√(2) then
