She used 3.36 pints of white paint. if you were to convert the fraction to 60% then you would just have to find 40% of 8.4 and thats 3.36.
Answer: 212.5%
Step-by-step explanation: To convert
to a percent, we will first need to change
to an improper fraction. To write a mixed number as an improper fraction, first multiply the denominator by the whole number and then add the numerator.
8 x 2 = 16
16 + 1 = 17
original denominator = 8.
Improper fraction → ![\frac{17}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B8%7D)
Now, to convert a fraction to a percent, first remember that a percent is a ratio of a number to 100. If we want to convert 17/8 to a percent, we need to find a fraction equivalent to 17/8 that has a 100 in the denominator. We can do this by setting up a proportion.
![\frac{17}{8} = \frac{n}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B8%7D%20%3D%20%5Cfrac%7Bn%7D%7B100%7D)
Now, we can use cross products to find the missing value.
8n = 1700
÷8 ÷8 ← divide both sides by 8
n = 212.5
Therefore, 2 and 1/8 is equivalent to 212.5%.
X=number of bags of peanuts.
y=number of cups of lemonade.
We suggest this system of equations.
0.35x+0.75y=7.05
y=x+5
solve by substitution method.
0.35x+0.75(x+5)=7.05
0.35x+0.75x+3.75=7.05
1.1x=7.05-3.75
1.1x=3.3
x=3.3/1.1=3
y=x+5
y=3+5=8
Answer:
8 cups of lemonade
Answer:
first, u need to know the formula for compound interest, which is:
![A = P(1 + \frac{r}{100})^{n}](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7B100%7D%29%5E%7Bn%7D)
where A is the final amount
P- initial amount
r- percent compounded(interest)
and
n- number of years
so
we have
![A = 475(1 + \frac{3.8}{100})^{4}](https://tex.z-dn.net/?f=A%20%3D%20475%281%20%2B%20%5Cfrac%7B3.8%7D%7B100%7D%29%5E%7B4%7D)
3.8/100 = 0.038
1+0.038 =1.038
1.038^4 = 1.160885573136
475 * 1.160885573136 = 551.4206472396
approximately $551.42
