Rename 7/20 as a percent

igomit [66]

Step-by-Step Explanation:

a) Rename $\frac{7}{20}$ as a percent

$\frac{7}{20}\times 100\\\\=7\times 5\\\\=35\%$

b) Rename .245 as a percent

$.245\times 100\\\\=\frac{245}{1000}\times 100\\\\=24.5\%$

c) Rename 28% as a fraction and a decimal in simplest form

$28\%=\frac{28}{100}=\frac{7}{4}\text{ as a fraction}\\\\\frac{7}{4}=1.75\text{ as a decimal}$

d) Put .367,36.5%, $\frac{9}{25}$ in order least to greatest.

$\text{ First we put change all into percent form}\\\\.367\times 100=\frac{367}{1000}\times 100=36.7\%\\\\\frac{9}{25}\times 100=9\times 4=36\%$

Now, we have 36.7%, 36.5%, 36%

We have write it in ascending order i.e. least to greatest ,

Here it is,

36%, 36.5%, 36.7%

$\frac{9}{25},36.5\%\ and\ .367$

Hi there!

quarter:18

1.Find common denominator in 4 and 1/2:

$4=\frac{1}{4}$

$\frac{1}{2}=\frac{2}{4}$

2.Convert 4 2/4 into mixed number:

$4\frac{2}{4}=\frac{18}{4}$

3.Divide 18/4 by 1/4:

$\frac{18}{4}*\frac{1}{4}=18$

What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?

tangare [24]

Answer:

{6,7,8,9,10}

Step-by-step explanation:

Solve the inequality using inverse operations.

$3r\leq 4r-6\\3r-4r\leq -6\\-r\leq -6\\r\geq 6$

This solution means values equal to or larger than 6 from the set are solutions. This means 6, 7, 8, 9, and 10 are the solution set.
