<h3>
Answer: 9 months</h3>
================================================
Work Shown:
100 + 22x = 298
22x = 298-100 ........ subtracting 100 from both sides
22x = 198
x = 198/22 .............. dividing both sides by 22
x = 9
It will take 9 months for her to pay off the sofa.
She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.
Answer:
524cm^2
Step-by-step explanation:
Formula for Volume of sphere= 4/3 πr^2
We have,
r=5cm
Now,
Volume(v)=4/3 πr^2 = 4/3π 5^3= 4/3π 125 = 166.666666667π = 523.598775599
Rounding to the nearest tenth,
Volume=524cm^2
