The total number of pages = 288
Already read 90
Remaining 288-90 = 198 pages
At the rate of 20 pages a day, she needs 198/20 days =9.9 days.≈ 10days
Answer:
The one that makes more sense for our conclusion is that the rocket crashes approximately 6.299601 seconds after it has been launched given the path of the rocket is .
Step-by-step explanation:
The rocket has crashed on the ground when the height between the ground and the rocket is 0.
We want to find the time, , such that the height, , is 0.
We are going to solve the following equation:
with
Upon comparing this equation to , I see that I have the following values for and :
The quadratic formula is:
.
Let's plug in the values we got above now.
This gives us either:
Let's punch both of these into the calculator:
The one that makes more sense for our conclusion is that the rocket crashes approximately 6.299601 seconds after it has been launched.
Marilyn's net pay will increase by $18.15 as her Federal Withholding Allowance increases from 3 to 4.
<h3>What is Federal Withholding Allowance?</h3>
A Federal Withholding Allowance is an exemption that lowers the amount of income tax you must deduct from an employee's paycheck.
Given: The following are the deductible computation:
- For federal withholding allowance = 3:
- Social Security Tax: 6.2% of $810 = = $50.22
- Medicare tax : 1.45% of $810 = = $11.745
- State tax: (21% of 3)% of $810= = 0.63% of $810 = = $5.103
Total = $67.068; deducted amount of his gross pay = $810 - $67.068 $742.932 (3 federal withholding).
- For Federal Withholding Allowance = 4:
- State tax: (21% of 4)% of $810 = = 0.84% of $810 = = $6.8704
Thus, as we can see from the calculations, the State taxes increased from $5.103 to $6.8704. Hence, the net pay increases by $18.15 as the federal allowance increases from 3 to 4.

The distance covered by bicycle is 1.885 km.
What is distnace?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.
Given: A bicycle wheel with radius 30cm made 1000 revolutions.
We have to find the total distance covered by bicycle.
First to find the circumference of the bicycle wheel.
Circumference = 2πr
where, r is the radius.
Here r = 30.
So,
Circumference = 2 x π x 30 = 60π
Now to find the total distance,
D = circumference x number of revolutions.
D = 60π x 1000
D = 188,495.5592 cm
D = 188,495.5592 /1000 km
D = 1.88 km
Therefore, the distance covered by bicycle is, 1.885 km.

For this you should set up a proportion.
2/3. 1/3
------ = --------
x. 3/3
Then cross multiply 3/3 x 2/3 and divide by 1/3
2/3 x 3/3 = 6/9
6/9 \ 1/3 = 6/9 x 3/1 = 18/1
