Answer:

Write 400% as the ratio 400/100. To find an equivalent ratio, you know that 400 divided by 20 is 20, so 100 divided by 20 will give you the answer. 100 ÷ 20 = 5. Reza ate 5 grapes yesterday.

Answer:

What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.

To do it, let:

x: number of grapes that Reza ate yesterday

(x / 20) = (100/400).

Clearing x we have:

x = (100/400) * (20) = 5

answer

the number of grapes Reza ate yesterday was 5

(x^2y^3) = (xy^a)^b
Rainbow [258]

Answer:

C. \frac{3}{2}

Step-by-step explanation:

To find the value f b, we need to compare the exponents.

The given exponential equation is:

( {x}^{2}  {y}^{3} )^{3}  = ( {x}  {y}^{a} )^{b}

Recall and apply the following rule of exponents.

( {x}^{m}  )^{n}  = {x}^{mn}

We apply this rule on both sides to get:

{x}^{2 \times 3}  {y}^{3 \times 3} =   {x}^{b}  {y}^{ab}

Simplify the exponents on the left.

{x}^{6}  {y}^{9} =   {x}^{b}  {y}^{ab}

Comparing exponents of the same variables on both sides,

b = 6 \: and \:\: ab = 9

\implies \: 6b = 9

Divide both sides by 6.

b =  \frac{9}{6}

b =  \frac{3}{2}

Answer:

  $6307.95

Step-by-step explanation:

The compound interest formula can help with that.

  A = P(1 +r/n)^(nt) . . . . value of principal P at rate r for t years, compounded n times per year.

  P = A(1 +r/n)^(-nt) = $8000(1 +0.04/2)^(-2·6) = $8000(1.02^-12) = $6307.95

Momba needs to deposit $6307.95 today to have $8000 in 6 years.

sergeinik [125]

Answer

Find out the what is the clearance price of a manatee.

To prove

As given

The gift shop at manatee mall was having a clearance sale.

Everything was marked down 30%.

The original price of a manatee hat was $12.

30 % is written in the decimal form.

= \frac{30}{100}

= 0.30

30% of the original price of a manatee = 0.30 × 12

                                                                 = $ 3.6

Clearance price = original price - 30% of the original price

                          = 12 - 3.6

                        = $ 8.4

Therefore the clearance price be $8.4 .
