Morgan has an 8 1/2 foot board that must be cut into boards that are feet long. How many of the smaller boards can he get from the 8 1/2 foot board?

Which of the following equations could you use to solve the problem?
x * 8 1/2 = 5/6
8 1/2 * x = 5/6
5/6 * 8 1/2 = x
8 1/2 / 5/6 = x

Answers

Answer:

8 1/2 / 5/6 = x

Step-by-step explanation:

8 1/2 foot board to be cut into 5/6 feet boards.

Number of smaller boards is:

8 1/2 ÷ 5/6 = 17/2 ÷ 5/6 = 17/2 × 6/5 = 51 / 5 = 10 (the whole part)

Zoe planted a 4-foot oak tree in her backyard. The oak tree is expected to grow by 22 inches each year. If the oak tree grows at its expected rate, which of the following functions represents the height, H(x), in inches, of the oak tree after x years?

A.
H(x) = 22x + 48

B.
H(x) = 22x + 4

C.
H(x) = 48x + 22

D.
H(x) = 4x + 22

Answers

H(x)=22x+4 would be the answer because your starting number is 4 and it increase by 22 each year x
The answer is A because it will grow 22inches (H) each year (x) and it has already started with 48 inches

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 10 child bikes and 12 adult bikes in a week (1 point) No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.

what is the fraction for the right handed people

Answers

Answer:

Step-by-step explanation:

12% is equivalent to 12/100.  This reduces to 3/25.  Thus, 3/25ths of the students are left-handed.  The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths.  There are more right-handed people (22/25ths) versus left-handed people.

Yes the answer above is right. 12% of the class is left but in fraction form it is 12/100 because a whole percent is 100% so 12 out of 100 is 12% :) hope it helped

2. y=90x+50
3. y= -50x+90

B. y=90x+50

Step-by-step explanation:

How do you solve 42 = 7/6x
Please help me and explain so I can do this on my own.

Answers

It really isn’t that hard

Answer:

I'm just trying to help so I don't know if it's correct

42 = 7/6x

you are going to multiply by 6x on both sides then you'll get and cancel the 6x on the right side of the problem

6x × 42 = 7

then you are going to divide by 42 on both sides and cancel the 42 on the left side of the equation, so you'll get 6x = 7/42

next simplify the equation

6x = 1/6

then you will try to get X by itself by dividing by 6 on both sides of the equation

so you'll get X = 1/6 ÷ 6

then you'll flip the second number and you'll get 1/6 then multiply so X will be equal to 1/36

hope you understand

Some of the genetic variationresults in different phenotypes. The phenotypes that enhance survival arecalled adaptations.

The increase inadaptations causes an increase in genetic variation. The adaptations thatenhance survival lead to larger populations, which further increasesgenetic variation. Individuals with well-adapted phenotypes are moreLikely to survive and reproduce, leading to population evolution overgenerations.Genetic variation is high in a population, but random events cause it todecrease. Populations with fewer individuals and lower genetic diversityare able to undergo natural selection when selective pressures are high.The increase in selective pressure causes an increase in adaptations thatare better suited for survival This results in an evolutionary change of apopulationSelective pressures exist in nature and cause changes in a population.Populations with high selective pressures have higher rates of geneticchange, leading to an increase in genetic variation, Increased geneticvariation leads to some individuals having well-suited adaptations.
