Elizabeth works part-time to help pay for college. She has worked for the last 14 days without a day off for a total of 48 hours
Zinaida [17]
The answer if I am correct should be C. 6, since if you divide forty-eight by two you get twenty-four. Twenty-four divided by four equals six, and twenty-four divided by three equals eight, eight is the number that would be the remaining amount of days. Hope this helps you and have an amazing day!

A rectangular room is 4 times as long as it is wide, and it’s perimeter is 60 meters. Find the dimension of the room
brilliants [131]

Answer: the length is 24m

The width is 6 m

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the given rectangle is 60 meters. This means that

2(L + W) = 60

Dividing through by 2, it becomes

L + W = 60 /2

L + W = 30 - - - - - - - - - - - - - -1

The rectangular room is 4 times as long as it is wide. This means that

L = 4W

Substituting L = 4W into equation 1, it becomes

4W + W = 30

5W = 30

W = 30/5

W = 6

L = 4 × 6

L = 24

What is the perimeter of triangle ABC round each step by the nearest 10th see image. Thanks so much
Greeley [361]

Perimeter of the triangle ABC is 18.7 units.

Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).

Length of the side AB = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

AB = \sqrt{(-1-4)^{2}+(4+1)^{2}} =\sqrt{50}

AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)

Length of the side BC = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

BC = \sqrt{(0+1)^{2}+(-3-4)^{2}}

BC = \sqrt{50}

BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)

Length of the side CA =\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

CA = \sqrt{(4-0)^{2}+(-1+3)^{2}}

CA = \sqrt{20}

CA = 4.47 units = 4.5 ( rounded to the nearest 10th)

Perimeter of the triangle ABC = sum of all three sides = (7.1 + 7.1 + 4.5) units = 18.7 units
