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%

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

Write an exponential function in the form y=ab^xy=ab

Tcecarenko [31]

Answer:

y = 8 · 10ˣ

Step-by-step explanation:

y = abˣ

When x = 0, y = 8.

8 = ab⁰

8 = a

When x = 3, y = 8000.

8000 = 8b³

1000 = b³

10 = b

The function is:

y = 8 · 10ˣ
