Answer:
Ounces of strawberry juice: 20 ounces
Ounces of water: 80 ounces
Step-by-step explanation:
For this problem, we can use the equation:
x + y = 100 ounces
Where x = The number of ounces of strawberry juice
and y = The number of ounces of water
Since we know that Molly uses four times as many ounces of water for each ounce of strawberry juice, we can conclude that:
y = 4x
With this information, we can use substitution to solve for x.
x + y = 100 ounces
x + (4x) = 100
Combine like-terms.
5x = 100
x = 20
Now that we know the value of x, we can figure out how many ounces of strawberry juice and how many ounces of water Molly needs.
Since x = The number of ounces of strawberry juice, Molly needs to use 20 ounces of strawberry juice.
Since y = The number of ounces of water, Molly needs to use 80 ounces of strawberry juice. (y = 4x | x = 20 | y = 4(20) | y = 80)
~Hope this helps!~
15/4
how many times does 4 go into 15 without going over.....that would be 3 times....so 3 is ur whole number. 3 * 4 = 12......15 - 12 = 3...and 3 is ur numerator....the denominator stays the same
so ur answer is : 3 3/4
Answer:
5 5/16
Step-by-step explanation:
you just divide 42 1/2 by 8
The formula that is useful for solving both of these problems is ...
9. Given v₁=15, a=9.8, d=10, find v₂.
... (v₂)² = 15² + 2·9.8·10
... v₂ = √421 ≈ 20.5 . . . . m/s
10. Given d=12 m when a=-9.8 m/s² and v₂=0, find d when a=0.17·(-9.8 m/s²).
The formula tells us that d=(v₁)²/(2a), which is to say that the distance is inversely proportional to the acceleration. If acceleration is 0.17 times that on earth, distance will be 1/0.17 ≈ 5.88 times that on earth.
(12 m)/0.17 ≈ 70.6 m
