The wildflowers began blooming by my house at the beginning of March. The first week there were 88 blooms. After week two, there were 176 flowers in bloom. If the flowers continue to bloom at the same rate each week, how many flowers will there be after 6 weeks?
A. 264
B. 462
C. 528
D. 536

Answers

Answer: C. 528

Explication: 88x2 weeks= 176 so 88x6weeks=528

First, there were 88 blooms in one week, now they are asking how many flowers will there be after 6 weeks, so you take 88 multiply by 6 (88x6) which gives you 528...so technically you will get C.528

ANSWER: C.528

Penny reads 12 pages in 1/4 of an hour. What is the unit rate of pages per hour, and what is the unit rate of hours per page? I know the unit rate of pages per hour is 48, but I am stuck on the unit rate of hours per page. I'm coming up with .020833. Please help. Thanks.

Answers

Your correct because 1/4 isn’t necessarily an hour it’s 15 minutes. So if yu divide that you would get .020833 yu would just have to round.

Penny can read 1 page in 1 minute and 14 seconds.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Penny reads 12 pages in 1/4 of an hour.

Now In (1/4)×4 hours, Penny can read (12×4) pages which is in 1 hour she can read 48 pages.

Now to obtain the unit rate of hours per page is we have to divide 1 hour by 48 pages which is (1/48) = 0.020833 hours or (0.020833×60) minutes = 1.24 minutes or 1 minute 14 seconds.
