Melillo Middle School prepared 30 cups of trail mix for a carnival. The ratio of nuts to dried fruit in the trail mix was 3 to 2. If the teachers ate 6 cups of nuts out of the mix, how many cups of dried fruit would need to be taken out in order to keep the original ratio?

Answers

4 cups of dried fruit would need to be taken out to keep the original ratio.

Given:
30 cups of trail mix.
ratio of nuts to dried fruit is 3 to 2.

3:2 = 6:x
3x  = 2*6
3x = 12
3x/3 = 12/3
x = 4  cups of dried fruits
ratio is 3:2
30 total
3+2=5
30=5 units
divide by 5
6=1 unit

at first there is
3(6):2(6)=18:12
18 nuts and 12 dried fruit
if teachers ate 6 nunts then hoa much fruit must be taken out to keep it same

18-6=12
12:x=3:2
treat as fraction
12/x=3/2
multiply both sides by x to clear x
12=3x/2
multiply both sides by 2 to cleaer fraction
24=3x
divide by 3
8=x

it needs to be 8
12-x=8
subtract 12 from both sides
-x=-4
multiply -1
x=4



4 cups must be taken out

Answer:

(1)/(8a^9b^12)

Step-by-step explanation:

((a^(-3))/(2b^4))^3 =

= ((1)/(2a^3b^4))^3

= (1)/(8a^9b^(12))

Answer:To simplify the expression "a raised to the negative third power over quantity 2 times b raised to the fourth power end quantity all cubed", we can follow these steps:

Step 1: Simplify the numerator.

a raised to the negative third power is equivalent to 1 over a cubed.

Step 2: Simplify the denominator.

2 times b raised to the fourth power is equivalent to 2b to the fourth power.

Step 3: Combine the simplified numerator and denominator.

So, the expression becomes 1 over a cubed divided by 2b to the fourth power, all cubed.

Step 4: Simplify the division.

When we divide by a fraction, we can multiply by its reciprocal.

The reciprocal of 2b to the fourth power is 1 over 2b to the fourth power.

Therefore, the expression simplifies to 1 over a cubed times 1 over the reciprocal of 2b to the fourth power, which is 1 over 2b to the fourth power.

In summary, the simplified expression is 1 over 2b to the fourth power times a cubed.

A store marks up an item from $50 to $100. a. What is the percentage increase?

b. $100 is what percentage of $50?

Answers

A) it is a 100% increase 

B) 200% of $50
a.) Half of 100 is 50. So that means that the percentage increase is 50%.
b.) Same as a, 
100%/x% = 100/50
(100/x)*x = (100/50)*x Multiply both sides by x
100 = 2*x
100/2 = x
50 = x
x= 50
