Mathematics
1 answer:
igomit [66]3 years ago
7 0

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

Help!!!<br> Slove for x.<br> A.11<br> B.9<br> C.13<br> D.14
olga nikolaevna [1]

Answer:

Step-by-step explanation:

The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.

7/(x + 7) = 6/(15 + 6)         Cross Multiply after combining

7 / (x + 7) = 6/(21)                

6 * (x + 7) = 7 * 21             Remove the brackets

6x + 42 = 147                   Subtract 42

6x = 147 - 42

6x = 105                           Divide by 6

x = 17.5

I think I've done this correctly. If you find an error, please let me know and I'll open it for editing.
