Answer:
Its c
Step-by-step explanation:
1. Convert the percents to decimals (you can do this by dividing each # by 100);
8/100= .08
15/100= .15
2. First take off the 8%;
$55.35 * .08 = $4.43
3. Take off the 15% (still use the original bill amount);
$55.35 * .15 = $8.30
4. Add the $ together after find the rate for each percent.;
$4.43 + 8.30 = $12.73
5. Subtract the add rates from the bill;
$55.35 - $ 12.73 = $42.62(answer)
Answer:
h+r=34
r=34-h.....1
total surface area=2πr(r+h)
2992=2πr×34
2992/34=2πr
88/2=22/7×r
44×7/22=r
r=2×7=14cm
Long way is to plug in 0 for the x, which ends up being y=b
most people take a shortcut and call b the y-intercept when it's y=mx+b form
