b. 4 1/2 feet
c. 12 3/4 feet
d. 13 1/4 feet

Answers

4.5 into a fraction is 4 1/2. 4 1/2 + 8 3/4 is 13 1/4 feet.

Answer:

The answer is d. 13 1/4 feet PLEASE MARK BRAINLIEST

Step-by-step explanation:

the 8 feet plus the 4 feet from the 4.5 feet makes 12 feet plus the fractions so 8 inches is 1/4 feet and 8 inches plus 5 inches on the 4.5 feet makes 13 inches which is 13 1/4 feet so 8 3/4 feet + 4.5 feet = 13 1/4 feet

$Rewrite the equation below so that it does not have fractions.$

Answers

Answer:

x= - 50/9

Step-by-step explanation:

multipy both equations by 12

9x+60=10

then move the constant to the right hand side and change it's sign

9x= 10 - 60

calculate difference

9x = -50

divide both sides by 9

x= - 50/9

We can simply multiply each number by 12 to get rid of fractions and our new equation is:
9x + 60 = 10

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?

Answers

She will need to cover a total of 268 square inches of wrapping paper.

She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:

2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276

So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.

To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.

- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.

So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.

Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.

Answer:280 in

Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

PLS HELP ! Solve the addition equation by finding a common multiple. one half + two thirds + four sixths equals ___

Answers

Answer: 1/2 + 2/3 + 4 /6 = 11/6

Step-by-step explanation:

1/2 + 2/3 + 4 /6

We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.

Note that we do not change 4/6, since it already has a denominator of 6.

==> 3/6 + 4/6 + 4/6

Add;

==> 11/6

3/6 + 4/6 + 4/6 equal to 11/6

Hope this helped!

Answer:

77.5

Step-by-step explanation:

Given:

Scores: 65, 70, 75, 80, 85, 90, 95

Number of Students: 8, 5, 3, 6, 6, 4, 2

Step 1: Calculate the sum

Sum = (65 * 8) + (70 * 5) + (75 * 3) + (80 * 6) + (85 * 6) + (90 * 4) + (95 * 2)

= 520 + 350 + 225 + 480 + 510 + 360 + 190

= 2635

Step 2: Calculate the mean

Mean = Sum / Total Number of Students

= 2635 / (8 + 5 + 3 + 6 + 6 + 4 + 2)

= 2635 / 34

≈ 77.5

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.
