Answer:
D. 21.
Step-by-step explanation:
The general form of the equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2 where r is the radius.
Comparing:
(x + 5)^2 + (y + 7)^2 = 21^2
So r^2 = 21^2
making r = √21^2
= 21.
Answer:

Step-by-step explanation:
<em>Given :</em>
<em>Maria got a prepaid debit card with $20 on it. </em>
<em>For her first purchase with the card,</em>
<em> she bought some bulk ribbon at a craft store.</em>
<em> The price of the ribbon was 8 cents per yard.</em>
<em>To Find:</em>
<em> If after that purchase there was $19.12 left on the card, how many yards of ribbon did Maria buy?</em>
<em>Solution:</em>
<em>$20- 19.12= 0.88</em>
<em>She spent 0.88 on the ribbon</em>
<em>One yard of ribbon is $0.08</em>
<em>0.88/0.08 = 11</em>
<em>Therefore she bought 11 yards of ribbon</em>
