You have two circular flower beds, as shown. The sum of the areas of two flower beds is 136 pi square feet. Find the radius of e
finlep [7]

Answer:

Radius of larger flower bed = 10 feet

Radius of smaller flower bed = 6 feet

Step-by-step explanation:

<u>Complete question:</u>

"You have two circular flower beds, as shown. The sum of the areas of two flower beds is 136 pi square feet. Find the radius of each bed.<em>"</em>

<em>Radius of larger flower bed = r</em>

<em>Radius of smaller flower bed = r - 4</em>

<em />

Now,

Area of circle is  \pi r^2

Since, total area is 136\pi, we can write:

\pi r^2 + \pi (r-4)^2=136\pi

Expanding and solving for r:

\pi r^2 + \pi (r-4)^2=136\pi\\r^2+(r-4)^2=136\\r^2 + r^2 - 8r + 16 = 136\\2r^2-8r-120=0\\2(r+6)(r-10)=0\\r=-6,10

Radius cannot be negative, so r = 10  &  r-4 = 10 -4 = 6

Radius of larger flower bed = 10 feet

Radius of smaller flower bed = 6 feet

Chien always works 20 hours/week at $15/hour and gets paid every 2 weeks.
Leto [7]

Answer:

  • $600
  • net pay
  • taxes, insurance, retirement plan contributions
  • net pay

Step-by-step explanation:

The gross pay that shows up on your paycheck is the sum of wages, commissions, and any other earnings your employer may share with you (tips, insurance offsets, bonuses). From this gross pay, government regulations may require the deduction of taxes of various kinds. Your employer may deduct the cost of insurance, and you may voluntarily have amounts deducted for additional taxes, insurance, union dues, or retirement plan contributions. The pay that you take home is the net pay after these deductions.

__

Chien gets paid at the rate of $15 per hour for 20 hours per week and 2 weeks per pay-period. We are not told of any other earnings or contributions to his gross pay. So, it will be ...

  ($15/h)(20 h/wk)(2 wk/period) = $600/period

Chien's gross pay will be $600 each pay period.

__

As discussed above, "net pay" and "take-home pay" are synonymous.

__

As discussed above, there may be a variety of deductions from his gross pay that will reduce his net pay. Often the largest of these is income tax together with Social Security tax. There may be additional deductions for insurance, union dues, health plan contributions, and retirement plan contributions.

__

Chien's budget should be based on money he <em>actually has available to spend</em>. That would generally be his net pay.

If Chien is considering changing jobs or his family situation, changes to payroll deductions may figure into his budget. Ordinarily, those costs would be considered "fixed" and not subject to a budgeting process.

the length of a rectangle is 6 inches more than twice it's width.If the perimeter of a rectangle is 60,find it's dimensions.​
levacccp [35]

Answer:

<h2>length = 22 inches</h2><h2>width = 8 inches</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 60 in

The statement

the length of a rectangle is 6 inches more than twice it's width is written as

l = 6 + 2w

Substitute the statement into the above formula

That's

60 = 2( 6 + 2w) + 2w

60 = 12 + 4w + 2w

6w = 60 - 12

6w = 48

Divide both sides by 6

w = 8

Substitute w = 6 into l = 6 + 2w

That's

l = 6 + 2(8)

l = 6 + 16

l = 22

The dimensions are

length = 22 inches

width = 8 inches

Hope this helps you

Find the value of y.
Alexandra [31]

Answer. First option: -1

Solution:

We have a triangle, and we know two angles of 60° each one. We can find the third angle A, using:

A+B+C=180°, with B=60° and C=60°:

A+60°+60°=180°

Solving for A: Adding similar terms:

A+120°=180°

Subtracting 120° both sides of the equation:

A+120°-120°=180°-120°

A=60°

The third angle A is 60° too, then the triangle has three equal angles of 60° each one, and it is an equillateral triangle, thus its three sides must be congruents:

2y+6=4=2x-3

We need to find the value of y, then using the first equality:

2y+6=4

Solving for y: Subtracting 6 both sides of the equation:

2y+6-6=4-6

2y=-2

Diniding both sides of the equation by 2:

2y/2=-2/2

y=-1
