400,000,000 = 4 x 10^8
Answer: reminder u are loved. <3
Step-by-step explanation:
Answer:
Part A: 9.75x > 195
Part B: x > 20
Step-by-step explanation:
Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.
We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195
divide both sides by 9.75 to solve for x
x > 20
surface area of cylinder = 2*pi*r*h + 2*pi*r^2
= 2*8*14*pi = 224pi
+ 2*8^2*pi = 128 pi
224+128 = 352
so answer is 352 pi
