Answer:

Scale factor of the dilation is 3            

Step-by-step explanation:

Given a quadrilateral with vertices at A(4, -4), B(4, -16), C(12, -16), and D(12, -4) has been dilated with a center at the origin. The image of D i.e coordinates of D after dilation are (36,-12).

we have to find the scale factor of the dilation.

As we know if the scale factor for dilation is k the new coordinates after dilation can be calculated as

(x,y) → (kx,ky)

As image of D given i.e

D(12,-4) → D'(36,-12)

⇒ 12 → 12k i.e 12k=36 ⇒ k=3

and -4 → -4k i.e -4k=-12 ⇒ k=3

hence, scale factor of the dilation is 3

I think the answer is 3, because D(12;-4) and D' is (36;-12). Then 36/12=3, -12/-4=3
(I hope it's true)!!! :)

A club collected $3,472 to buy computers. If each computer cost $680, estimate the number of computers that the club can buy.exp
almond37 [142]

The club can buy 5 computers with $3472

Step-by-step explanation:

The number of computers which can be bought from the given amount will be calculated by dividing the amount by price of one computer.

Given

Total amount = $3472

Price of one computer =$680

The number of computers will be:

=\frac{Total\ amount}{Price\ per\ computer}\\=\frac{3472}{680}\\=5.1\\

As the number of an item cannot be in decimal it will be rounded off to 5.

The club can buy 5 computers with $3472

Using the approximation 3.14 for \pi what is the radius of a circle with circumference 44m
Feliz [49]

Answer:

7 m

Step-by-step explanation:

Circumference of a circle uses the formula;

Circumference = 2 × pi × radius(r)

If the circumference = 44

then we use the formula above to calculate the value of the radius,

44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))

Radius = 44 ÷ ( 3.14 × 2)

;Radius = 7.01

;Radius = 7m
