Estimate 6254 to 6000. 2 times 6000 equals to 12000
MrRa [10]3 years ago
4 0
First round 6254 to 6000 then multiply it by 2.
6,254=6,000x2=12,000
If you need help on the multiplying bit here is how you do it: 
First take the whole numbers so 6 and 2. Next multiply them. 6x2=12. Then all you do is add the zeros. So in this case there are three zeros so 12,000 is your estimated answer.

Proving circles are similar: Choose any of the transformations that would be a step in proving that Circle A is similar to Circl
Ulleksa [173]

The transformations that would prove that circles A and C are similar are:

  • A. Reflect A over the line y=x
  • C. Dilate A by 3/2

<h3>How to prove that circle A and circle C are similar?</h3>

The circles are given as:

Circle A and B

Assume the following parameters:

  • The center of circle A is (2,3) with a radius of 2
  • The center of circle B is (3,2) with a radius of 3

To start with;

The circle A must be reflected across the line y = x with the following transformation rule:

(x,y) -> (y,x)

So, we have:

(2,3) -> (3,2)

Next, the radius of A must be dilated by 3/2 as follows:

New Radius = 3/2 * 2 = 3

After the transformations, we have the following parameters:

  • The center of circle A is (3,2) with a radius of 3
  • The center of circle B is (3,2) with a radius of 3

Notice that both circles now have the same center and radius.

Hence, both circles are similar

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower
Korolek [52]

The question is incomplete. The complete question is :

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?

Cost of lawn mower = $ 200

Cost of gasoline = $ 2 per lawn

Solution :

Given :

Cost of the lawn mower = $ 200

The cost of gasoline expense for one lawn = $ 2

The revenue generated for one lawn = $ 25

So let the number of lawn to be mowed = x

Therefore the total expenses = $200+2x$

So, the total revenue = $25x$

The point for which the revenue will exceed the total expenditure will be :

$25x \geq 200+2x$

So at x=9,  \ 225 > 218

Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.

USPshnik [31]

Answer:

y ≈ 16.33  

Step-by-step explanation:

∆SPQ is a 30-60-90 right triangle  

PS:QS:PQ = 1:2:√3

    QS/PQ = 2/√3

    QS/PQ = QS/10

     QS/10 = 2/√3     Multiply each side by 10

         QS = 20/√3

∆RSQ is a 45-45-90 right triangle.

∴ RS = QS  = 20/√3

   RS²     +    QS²      = QR²

(20/√3)² + (20/√3)² =   y²

  400/3   +  400/3   =    y²

                   800/3   =    y²     Take the square root of each side

                             y = √(800/3)

                                = 20√(2/3)

                                = (20√6)/3

                                ≈ 16.33
