yanalaym [24]

Answer: $1846

Step-by-step explanation:

First and foremost, we should note that there are 52 weeks in a year. Therefore the biweekly payment of John will be gotten by dividing his gross income by 26 weeks i.e (52weeks/2) since it's biweekly.

Therefore, the gross income on each paycheck will be:

= $48,000.00 / 26

= $1846.15

= $1846 approximately

The gross income on each paycheck is $1846.

Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?
Scrat [10]

Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

\text{Circumference of a circle}=2\pi r

Upon substituting the measure of circumference in above formula we will get,

28.3=2\pi r  

r=\frac{28.3}{2\pi}

r=4.504084889500638\approx 4.5

Therefore, the radius of circle O is 4.5 cm.

The ratio of the number of adults to the number of children at the resturant is 3:7. Identify the choices below that represent a
klasskru [66]

Answer: A: 6:14

C: 15:35

E: 30:70

Step-by-step explanation:

From the question, we are given that the ratio of the number of adults to the number of children at the resturant is 3:7.

The choices below that represent an equivalent ratio goes thus:

A: 6:14

This can be represented as: 6/14. The common factor is 2 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

B: 8:12

This can be represented as: 8/12. The common factor is 4 and we reduce to lowest term which would be: = 2/3 = 2:3

This is not an equivalent ratio.

C: 15:35

This can be represented as: 15/35. The common factor is 5 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

D: 21:9

This can be represented as: 21/9. The common factor is 3 and we reduce to lowest term which would be: = 7/3 = 7:3

This is not an equivalent ratio.

E: 30:70

This can be represented as: 30/70. The common factor is 10 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

The correct options are A, C,and E.
