Answer:
n=5
Step-by-step explanation:
EASY
8 / 2 = 45 / x....8 servings to 2 cups = 45 servings to x cups
cross multiply
(8)(x) = (2)(45)
8x = 90
x = 90/8
x = 11 1/4 (or 11.25) cups of flour are needed <==
If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
Answer:
1) 1.5 ft²
2) 2400 ft²
3) Both 96 ft²
Step-by-step explanation:
1) 6 in = 0.5 ft so we have 3 ft * 0.5 ft = 1.5 ft²
2) 80 yd = 240 ft so we have 10 ft * 240 ft = 2400 ft²
3) there is 6 squares of 4 ft * 4 ft, so that's 6 * 4 ft * 4 ft = 96 ft². Area of net and surface area describe same thing.
