Answer:

192 square feet is the total area of both rooms.

Step-by-step explanation:

<u>Key skills needed here: Rectangle Area, Operations</u>

1) She has 2 identical rooms and each one measures 8 ft. x 12 ft.

2) Most rooms are rectangles, so this one is one too.

3) The area of a rectangle is L x W, with L being the length and W being the width (check my image to learn more)

4) Now you can use the formula to find the area of one room and the multiply it by 2 since there are 2 rooms.

---->> A = L X W = 8 x 12 = 96

Each room is 96 square feet.

96 X 2  = 192

This means the total area is 192 square feet.

If 57 is added to a number, it will be 4 times as large as it was originally. Find the number.
Sonja [21]

Answer:

19

Step-by-step explanation:

X will refer to the number.

X+57( the number added to the original.)=4x. (x time 4)

X+57=4x.

Subtract x from both sides to get the variable on one side.

(X+57)-x =(4x)-x

57=3x. You would then divide by 3 on both sides to again get integer isolated.

57/3=3/3x.

57/3=19. 3/3=1.

19=x.

wolverine [178]

According to the given percentages, it is found that there is a 67% probability that a randomly selected man between the age of 25 and 34 does not search for green technology.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

We have that 33% of men search for green technology, hence, there is a 100 - 33 = 67% probability that a randomly selected man between the age of 25 and 34 does not search for green technology.

A young sumo wrestler goes on a special diet to gain weight.
Ilia_Sergeevich [38]

Answer:

10.8 kg

Step-by-step explanation:

w = 80 + 5.4t

At time 0, when he starts the diet, his initial weight is

w = 80 + 5.4(0)

w = 80

80 kg.

After 2 months, t = 2. His weight is

w = 80 + 5.4t

w = 80 + 5.4(2)

w = 80 + 10.8

w = 90.8

90.8 kg.

His gain in 2 months was 90.8 kg - 80 kg = 10.8 kg

Answer: 10.8 kg
