Answer:
30 small pretzels were sold that night.
Step-by-step explanation:
x = small pretzels
y = large pretzels
x + y = 50
2x + 4.5y = 150
x + y - y = 50 - y
x = 50 - y
2(50 - y) + 4.5y = 150
100 - 2y + 4.5y = 150
2.5y = 50
------- -----
2.5 2.5
y = 20
x + 20 = 50
x + 20 - 20 = 50 - 20
x = 30
Answer: 1/20 (fraction) or 0.05 (decimal)
Step-by-step explanation:
first i like to make them a decimal so its easier.
1/4 = 0.25
1/5 = 0.2
multiply 0.25 and 0.2 = 0.05
make 0.05 a fraction
1/20
simplify. (it's already in its simplest form)
the answer is 1/20 as a fraction or 0.05 as a decimal.
(i dont know which one ur teacher wants u to do fraction or decimal?)
Answer:
87.96 ft
Step-by-step explanation:
In order to find the circumference given the radius we use 2 pi r so it would be 2xpix14 which comes out to be 87.96
Answer:
4 ft
Step-by-step explanation:
The volume of a cube of side length s is V = s^3. Solving for s^3, we get:
s^3 = V, and so s = ∛V
In this case, with V = 64 ft³, the desired side length is
s = ∛(64 ft³) = 4 ft
