A*2 + b* = c*2
(9)*2 + (8)*2
81+64= 145
145=c*2
12.04=c
Answer:
7 quarters are spent for throwing 350 food pebbles in pond.
Step-by-step explanation:
Given:
Reggie receives 50 food pebbles for every quarter he spends.
Number of food pebbles he has = 350
Let the number of quarters spent for 350 pebbles be 'x'.
Now, using proportion and cross multiplication method, we can find 'x'.
<u><em>1 quarter is equivalent to 50 pebbles thrown in pond.</em></u>
<u><em>So, 'x' quarters is equivalent to 350 pebbles thrown in pond.</em></u>

So, 7 quarters are spent for throwing 350 food pebbles in pond.
We know that there are 7 days in a week, so just divide 68 ÷ 7 and you should get 9.71 which is approximately 10 weeks
It’s also 64 because the angles are congruent
