An employee receives a pay increase from $35,000 per year to $37,500 per year. Calculate the percent increase. Round to the near
arsen [322]

Answer:

The percentage increase in salary of employee is 7.14 %  

Step-by-step explanation:

Given as :

The initial pay of employee = $35,000 per year

The increase pay of employee = $37,500 per year

Let The percentage increase in salary =  X %

So, X  = \frac{increase salary - initial salary}{initial salary}  × 100

Or, X  = \frac{$37,500 - $35,000}{$35,000}  × 100

Or,  X  = \frac{$2,500}{$35,000}  × 100

∴     X = 0.0714  × 100  = 7.14 %

Hence The percentage increase in salary of employee is 7.14 %   Answer

Find 5 Rational Numbers Between 1 and 2 using (a+b/2) where a=1 and b=2.
mojhsa [17]

Answer:

There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.

As we have to find 5 rational numbers between 1 & 2

Take 5 and add 1 to it i.e. 5+1= 6

Now take the first number and multiply and divide it by 6 i.e.

1x6/6 = 6/6

Also take the second number and multiply and divide it by 6 i.e.

2x6/6= 12/6

This is done to convert 1 & 2 into rational number i.e. in form of p/q

Now we have two numbers 6/6 and 12/6 so five rational numbers between them are

7/6, 8/6, 9/6, 10/6, 11/6

The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.

Anna drives 15,500 miles a year for work. On average, how many miles does she drive a week?
I am Lyosha [343]

Answer:

206 miles

Step-by-step explanation:

People generally work 5x a week so.. (15000 / 52)

52 indicates the amount of weeks in a year.

In total, that is 288.4 miles a week. Now, we're assuming she doesn't work on the weekend so we divide 288.4 by 7. That is 41.2 miles a day. Now, you times 41.2 by 5 and your answer should be 206 miles a week.

21 and 61 which is composite and which is prime
tia_tia [17]
21 is a composite, because 21 x 1 = 21, and 7 x 3 = 21

61 is a prime, because it can only be multiplied by 1 to get 61

hope this helps
