Answer:

See explanation

Step-by-step explanation:

You forgot to give the coordinates of C.

Note that, the mapping for 90° clockwise rotation around the origin is given by:

$(x,y)\to (-y,x)$

Assuming the coordinates of C were (-6,6), then the coordinates of C after a 90° clockwise rotation

around the origin is (-6,-6)

Identical sweaters are on sale in two different stores. The sale price in store A is 30% off the regular price of $25. The sale

bekas [8.4K]

30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> number of tennis balls

y ----> number of tennis rackets

we know that

To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets

In this problem we have

$\frac{x}{y}=\frac{5}{3}$

$x=\frac{5}{3}y$

That means

The number of tennis balls is three-fifths times the number of tennis rackets

see the attached figure to better understand the problem
