The circle shown has center o and radius 4. what is the area of the shaded region?

The ratio of his savings: expenses = 7: 5

So, total of the ratio is = 7 +5 =12

His savings will be 7/12* allowance

His expenses will be 5/12 * allowance

We know that the allowance that he gets is $3

His savings = 7/12 * allowances  

His savings = 7/12 * 3

His savings = $7/4 or 1 ¾  

Now, we convert the 7/4 (or 1 ¾) into a decimal.  

1 ¾ when converted is decimal is 1.75

His Savings = $1.75

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
