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:

<em>Cost of game = $120</em>

<em>Current savings = $30</em>

<em>Rate for babysitting (per hour) = $5/hour</em>

<em></em>

<em>So, required equation is :-</em>

<em>120 = 5h + 30</em>

<em>5h = 90</em>

<em>h = 18</em>

<em></em>

<em>She must make $90 by babysitting for 18 more hours.</em>

Easy question for all the points?
kaheart [24]

Answer:

D

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

9

Width is 9 feet shorter than the length
