A salesperson's weekly paycheck is 40% more than a second salesperson's paycheck. the two paychecks total $1025. find the amount
BARSIC [14]
Let
 x = salesperson's weekly paycheck
 y = second salesperson's paycheck
 We have the following system of equations:
 x + y = 1025
 x = 1.40y
 Solving the system:
 x + y = 1025
 1.40y + y = 1025
 2.40y = 1025
 y = 1025 / 2.40 = 427.0833333 $
 x = 1.40y
 x = 1.40 * (427.0833333) = 597.9166666 $
 answer:
 the amount of each paycheck is:
 first persons paycheck = 597.92 $
 second persons paycheck = 427.08 $

Which expression represents the area of the base of the cone? A cone with diameter 12 inches, height 8 inches, and slant height
Wewaii [24]

Answer: (pi) (6 squared)

Step-by-step explanation:

Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:

Area of a circle: (pi) radius^2

The diameter (d) of a circle is equal to: 2 radius

So:

D = 2r

Replacing with the value given:

12 =2r

12/2=r

radius= 6 inches

Back with the Area formula:

A = (pi) 6^2

You spend 15 minutes reading email. You then spend 3 hours watching television. Write the ratio of the amount of time spent read
timurjin [86]

The amount of time spent reading email to the amount of time spent watching television is 1/12

Step-by-step explanation:

Given

Time to read email = 15 minutes

Time on television =  3 hours = 3*60 minutes = 180 minutes

Ration is the fraction between two things. In this case, the ration is from the amount of time spent reading email to the amount of time spent watching television

So,

Required ratio will be: 15/180

Simplifying => 1/12

So,

The amount of time spent reading email to the amount of time spent watching television is 1/12
