Answer:

30 students

100 ÷ 20 = 50

60 ÷ 2 = 30 students

30 of the 50 students are 12 years old.

Step-by-step explanation:

60% of 50

60 : 100

X : 50

60/100 × 50

Answer:

60 ÷ 2 = the number of students who are 12 years old.

60 ÷ 2 = 30 students

30 of the 50 students are 12 years old.

Step-by-step explanation:

Change the percent to a decimal

.60 *50 =30

We can rewrite the decimal as a fraction

60/100 *50

We can change the order

60 * 50/100

60 *1/2

Multiplying by 1/2 is the same as dividing by 2

60 ÷ 2 = the number of students who are 12 years old.

60 ÷ 2 = 30 students

30 of the 50 students are 12 years old.

If a person lnvests $120 at 8% annual interest, find the approximate value of the investment at the end of 5 years
Pie

Answer:

$176.3193692 or $176.32 (rounded to two decimal places)

Step-by-step explanation:

It is a compound interest, which means the interest accumulates on an initial amount each period.

The formula is A=P(1+R)^n

A= the total amount P=initial amount      R=rate   n=time (years)

P=$120   Rate= 8% or 0.08 (decimal)  n=5 (years)

A=120 (1+0.08)^2

A=120 (1.469328077)

A= 176.3193692

A washer and a dryer cost $995 combined. The washer cost $45 more than the dryer. What is the cost of the dryer?​
Talja [164]

When a washer and a dryer cost $995 combined. If  the washer cost $45 more than the dryer, then the cost of the dryer is $475

The combined cost of a washer and a dryer = $995

Consider the cost of a dryer as x

The washer cost $45 more than the dryer.

The cost of the washer = x+45

Then the equation will be

x+x+45 = 995

2x+45 = 995

2x = 950

x = 950/2

x = 475

The cost of the dryer is $475

Hence, when a washer and a dryer cost $995 combined. If  the washer cost $45 more than the dryer, then the cost of the dryer is $475
