Lydia wrote3/40 pages of her science report in one minute and her writing rate in pages per minute would be 0.075 in decimal form.
A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
We have been given that Lydia spent an hour writing her 4-and-a-half-page science report.
We initially convert an hour into minutes in order to answer this question.
∵ one hour = sixty minutes
Here fraction 4 1/2 which is equal to fraction 9/2 i.e. 4.5 in decimal form
After that, we divided 4 1/2 by 60. The solution is 0.075 in decimal form. That equals 3/40 when expressed as a lowest terms fraction.
Therefore, she wrote 3/40 pages of her science report in one minute.

B. Regular pentagon
C. Regular octagon
D. Square
Answer:
D. Square
Step-by-step explanation:
A square is a regular tessellation because a regular tessellation is a pattern made up of only one single shape placed in some kind of pattern.
One landscaper charges $20 for 5 hours of work.
One landscaper’s hourly rate is $15 lower than the other landscaper’s.
Both landscapers charge the same hourly rate and the same fee per job.
Both landscapers charge the same hourly rate, but not the same fee per job.
What Casey can conclude is D. Both landscapers charge the same hourly rate, but not the same fee per job.
Both landscapers will charge the same hourly rate because we were told they each charges an hourly rate including a fee for each job.
Their fees per job cannot be the same because Casey substituted an expression for one variable while he solved for the other.
Therefore the correct option is D.

Answer:
x =22.5
Step-by-step explanation:
x+3x = 90
x and 3x are complementary so they add to 90 degrees
Combine like terms
4x =90
Divide each side by 4
4x/4 = 90/4
x =22.5
answer: x = 22.5
explanation:
as the 3x and x are on a straight line with the angle of 90° we know that
3x +x = 90
4x = 90
x = 22.5
24x + 4y = 384, where x = number of minutes spent
producing fruit cans, and y = number of minutes
producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, how
many minutes would the fruit assembly line need to run to
complete the order of 384 cans? Explain
Answer:
8 minutes.
Step-by-step explanation:
24x + 64y = 384, that represents the canned goods order .
where x = number of minutes spent producing fruit cans,
and y = number of minutes producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, then put y=3 in equation we get
Therefore, the fruit assembly line need to run to complete the order of 384 cans in 18 minutes.
Answer:
Substitute 3 into the equation for y. Solve for x and find that x = 8. So if cans of vegetables are processed for 3 minutes, fruit needs to be processed for 8 minutes to complete the 384-can order.
