QveST [7]

Answer:

$\text{The length of new room}=16.64\text{ feet}$

$\text{Area of the new room}=266.24\text{ feet}^2$

Step-by-step explanation:

We have been given that the Rumpart family is building a new room onto their house. The width of the new room will be 16 feet.

The length of the room will be 4% greater than the width. This means that length of new room will be 16 feet plus 4% of 16.

$\text{The length of new room}=16+(\frac{4}{100}*16)$

$\text{The length of new room}=16+(0.04*16)$

$\text{The length of new room}=16+0.64$

$\text{The length of new room}=16.64$

Therefore, the expression $16+(0.04*16)$ represents the length of new room and the length of new room is 16.64 feet.

Since we know that area of a rectangular shape is width times length.

$\text{Area of rectangle}=\text{Length*Width}$

$\text{Area of the new room}=16\text{ feet}\times 16.64\text{ feet}$

$\text{Area of the new room}=266.24\text{ feet}^2$

Therefore, the area of the new room will be 266.24 square feet.

Allison wants to buy a game that costs $120. She has saved $30 for the game. She earns $5 per hour babysitting.

sergey [27]

Answer:

Step-by-step explanation:

Cost of game = $120

Current savings = $30

Rate for babysitting (per hour) = $5/hour

So, required equation is :-

120 = 5h + 30

5h = 90

h = 18

She must make $90 by babysitting for 18 more hours.

Easy question for all the points?

kaheart [24]

Answer:

Step-by-step explanation:

Height: h

Length: 2h + 15

Area = length × width

4h² + 42h + 90

2(2h² + 21h + 45)

2[2h² + 15h + 6h + 45]

2[h(2h + 15) + 3(2h + 15)]

2(h + 3)(2h + 15)

Width = 2(h+3) = 2h + 6

Length: 2h + 15

Difference:

(2h + 15) - (2h + 6)

2h + 15 - 2h - 6

Width is 9 feet shorter than the length
