Answer:

110/289 feet

Step-by-step explanation:

Step one:

given data

Area of the floor= 55/14 square feet.

The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet

Step two:

The expression for the area of the room is

Area= L*W

55/14= 17/2*W

55/14=17W/2

cross multiply

17W*14=55*2

289W=110

divide both sides by 289

W= 110/289 feet

If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours.
Svetllana [295]

Answer: 5\frac{1}{4} hrs

<u>Explanation:</u>

Jasper: \frac{1}{7} per hr

Yolanda: \frac{1}{x} per hr

Together: \frac{1}{3} per hr

Jasper + Yolanda = Together

\frac{1}{7} + \frac{1}{x} = \frac{1}{3}

(21x)\frac{1}{7} + (21x)\frac{1}{x} = (21x)\frac{1}{3}

3x + 21 = 7x

        21 = 4x

        \frac{21}{4} = x

         5\frac{1}{4}

What is 9.36•10~4 in standard form
marta [7]
With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.

So, if you just multiply these you get 9.36*10000, which is 93600.

Sophia started a lawn mowing business and charges a flat fee of $5.00 plus $3.50 per hour.
umka2103 [35]

Answer:

5 + 3.5h = 29.50

Step-by-step explanation:

The flat fee means that you will be paid the money with no change to it.

So you will not multiply it.

3.5h means that you are adding 3.50 every hour according to the question

So summary:

5+3.5h = 29.50

Evaluation:

5+3.5h = 29.50

24.50 = 3.5h

h = 7

Sofia worked 7 hours

If my answer is incorrect, pls correct me!
