.15 × 80 = 12
16 ounces in one pound
16 × 5 = 80
.15 × 80 = 12 ounces of food a day.
Rewrite as:
4y=x^2-12x+68
divide by four:
y= x^2/4-3x+17
your answer would be
(6,8)
You would need 88 boxes. dividing 962 by 11 would lead to 87.45, but the remains cannot just be left out therefore you’d need 88 boxes
Answer:
The astronaut must be at 1600 km from the earth to weight 64lb
Step-by-step explanation:
As the weight of an object varies inversely as the square of the distance from the center of the earth, that means that:
weight = k / distance² <em>(1)</em>
Where k is proportionality constant
Replacing:
100 lb = k/(6400km)²
100lb × 6400km² = k = 4,096x10⁹ lbkm²
Now, using (1):
64 lb = 4,096x10⁹ lbkm² / x²
x² = 4,096x10⁹ lbkm² / 64lb
x² = 6,4x10⁷ km²
x = √6,4x10⁷ km²
x = 8000 km
Distance from the center of the earth is 8000 km. Distance from the earth (At sea level):
8000km - 6400km =<em> 1600km</em>
I hope it helps!
