answer: -1
Step-by-step explanation:
The dimension of the rectangle should be 3x14 cm and 14 cm. Thus, its area is 3x14 cm x 14 cm which is equal to 588 cm². The area of the 3 circles is,
3A = 3πr² = 3π(14 cm/2)² = 147π cm² = 461.81 cm²
The area of the shaded region is the difference between the areas which is equal to 126.19 cm².
First you need to set up a formula. Underline all of your givens:
<u>Spent 1/2 on clothes
$6 more for washing windows
Ended with $10.
</u>
now you need to set up an equation.
<u>
</u>You know she ended up with $10. So that will be what it equals. Then you know that she earned $6 in addition to her allowance. So this would be (x= allowance) (x+6)/2 = 10.
<u>
</u>Now you need to solve for x.
Multiply both sides by 2.
<u>
</u>x+6=20<u>
</u>Now subtract both sides by 6 to get x alone:
<u>
</u>x=$14<u>
