Micheal and Tracy are carpeting their family room that is 14 1/2 feet long and 12 1/4 feet wide. To find the amount of carpet needed micheal says to multiply 15 1/2 and 12 1/4 and Tracy says to multiply 12 1/4 and 15 1/2 . Who is right how much carpet is needed

Answers

Answer:

Area of carpet = 177.625 ft²

Step-by-step explanation:

Given:

Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft

Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft

Find:

Area of carpet

Computation:

Area of carpet = lb

Area of carpet = (14.5)(12.25)

Area of carpet = 177.625 ft²

Micheal estimation = 15.5 x 12.25 = 189.875

Tracy estimation = 12.25 x 15.5 = 189.875

Both wrong.

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
A. 36 inches
B. 21 inches
C. 15 inches
D. 30 inches

Answers

Answer:

The length is 15 inches.

Step-by-step explanation:

Perimeter of rectangle = 2L + 2W

If W = 6, then 2W = 2*6, which is 12.

Now, 2L + 12 = 42.

Solve for L.

2L + 12 = 42

2L = 30

L = 15

Step-by-step explanation:

A farmer has 96 apples to sell at the farmers market. She wants to bag the apples before going. How many ways can the farmer bag the apples so that: each bag has at least 4 apples each bag has no more than 10 apples all bags have the same number of apples

Answers

Answer and explanation:

Farmer's number of apples = 96 apples

Given that Farmer needs to bag the apples so that there are at least 4 apples in each bag(not less than 4 apples in each bag) and not more than 10 apples in each bag

And also all apples in each bag are equal

We need to find the numbers between 4 and 10(including 4 and 10) that can divide 96 without a remainder

4 can divide 96= 24

5 cannot divide 96 without remainder

6 can divide 96 =16

7 cannot divide 96 without remainder

8 can divide 96=12

9 cannot divide 96 without remainder

10 cannot divide 96 without remainder

From the above we see that the factors of 96 = 4, 6, 8 between 4 and 10

4 apples = 24 bags

6 apples = 16 bags

8 apples = 12 bags

Therefore, there can be 3 possible ways of having equal number of apples in each bag between 4 and 10 apples

Step-by-step explanation:

and that

[tex]\angle 1 +\angle 2 = 180[/tex]

so we substitute angle 2 by angle 1

[tex]\angle 1 +\angle 1 = 180\\\\2\angle 1=180\\\\\angle 1 = 90[/tex]

Complete the equation of the line whose y intercept is (0, 6) and the slope is 3

Answers

Answer:

y=3x+6

Step-by-step explanation:

The slope form can be written as y=mx+b

m is the slope, which is 3 in this case.

b is the y-intercept (6).  

Add those values into the slope form equation.  Just leave y as is.

It’s y=3x+6 because if you solve for the y-intercept by doing 6=3(0)+b you’ll get b=6. Then you just plug in the m values and the b and you’ll get y=3x+6
