Answer:
64 cups of lemon juice
Explanation:
First, you can determine with the information provided the amount of cups of lemon needed to prepare sixteen cups of lemonade:
5 cups of lemonade→2 cups of lemon juice
16 cups of lemonade→x
x=(16*2)/5=6.4 cups of lemon juice
Now, you now that for sixteen cups that is the amount in a gallon you need 6.4 cups of lemon juice and you can use a rule of three to determine the amount needed for ten gallons of lemonade:
1 gallon of lemonade→6.4 cups of lemon juice
10 galons of lemonade→x
x=(10*6.4)/1=64 cups of lemon juice
According to this, the answer is that 64 cups of lemon juice are needed to make ten gallons of lemonade.
It is irrational.
A = π r^2 = π[3/4 cm]^2 = 9π/16 cm^2
An irrational number (Pi in this case) multiplied by a rational number (9/4) gives an irrational number.
Answer:
x = -2
Step-by-step explanation:
2x = -8+4
2x = -4
x = -2
CHECK
-4 - 4 = -8
<em>Answer:</em>
–6.8
<em>Method:</em>
Counting backwards from –7 to –6.5
Answer:
The answer is B.
Step-by-step explanation:
To obtain the inverse of a relation you simply interchange the x and y coordinates of each pair.
Here:
(3,1) becomes (1,3)
(3,1) becomes ((1,3)
(7, -7) becomes (-7,7) and
(12, -15) becomes (-15, 12)
