Answer:

The answer is provided as a whole explanation

Step-by-step explanation:

Regrouping is the presentation of a number or decimal with its number groups. For example, we can represent 0.25 in this way:

0.25 = 0.2 + 0.05

0.25 = 2 tenth + 5 hundredth

We can also write 0.25 as:

0.25 = 0.1 + 0.15

0.25 = 1 tenth + 15 hundredth

Regrouping is handy to simplify a mathematical calculation since we know how many tenth or hundredth we have got in this case.

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%

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

3x + 3<br> X + 8<br> What is the perimeter of each polygon?

Ganezh [65]

Answer:

D. 60

Step-by-step explanation:

4(3x + 3) = 5(x + 8) 12(4) + 12 5(4) + 40

12x + 12 = 5x + 40 48 + 12 20 + 40

-5x -5x 60 60

7x + 12 = 40

-12 -12

7x = 28

x = 4

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Today's cafeteria s

kobusy [5.1K]

Answer:

Equation 1: 14t + 61s = 150

Equation 2: 14t + 25s = 78

Use Elimination (x)

(-1) (14t + 25s) = (78) (-1)

-14t - 25s = -78

14t + 61s = 150

+ -14t - 25s = -78

--------------------------

36s = 72

s = 2

Salad costs $2

Then find t

14t + 61(2) = 150

14t + 122 = 150

14t = 28

t = 2

Sandwich costs $2
