One pound of grout is enough to grout a tiled area that is 110 sq. ft. Alyssa’s kitchen counter is made up of two rectangular segments. One is 10.3 ft by 2.5 ft, and the other is 3.1 ft by 2 ft. Which expression represents the number of pounds of grout Alyssa will need?

By taking the **quotient** between the** area **that one pound covers and the **area **of the kitchen, we conclude that Alyssa will need 0.29 pounds of grout.

We know that one pound of grout covers a total of **110 square feet.**

Alyssa's kitchen is made of two **rectangular segments**, one that measures 10.3ft by 2.5 ft, then the **area **of this **rectangle **is:

10.3ft*2.5ft = 25.75 ft²

The other **rectangle **has dimensions of 3.1ft by 2ft, so the **area **is:

3.1ft*2ft = 6.2ft²

The total **area **is:

25.75 ft² + 6.2ft² = 31.95 ft²

Now, with one pond of grout, they can cover 110 ft², then the number of pounds that Alyssa needs is:

N = 31.95 ft²/110 ft² = 0.29

Alyssa will need **0.29 pounds of grout.**

Caroline walks 9 1/2 inches per second. Give each rate in miles per hour. Round to the nearest tenth.

I got 32,400ft/hour. I divided that by 5,280ft because that’s 1 mile and I got 6.47. Rounded and got 6.5. The answer is .5 but I don’t understand how they got it.

9.5 or **9 1/2 inches per second** in **miles per hour** is 0.5 .**What is conversion of units?**

The process of translating measurements of a given quantity between different **units**, frequently using multiplicative** conversion factors **that change the value of the measured quantity without changing its effects, is known as **unit conversion**. The **specific circumstances** and the desired result dictate the **conversion process**. This may be** governed **by a regulation, contract, set of **technical requirements**, or other publicly available standards.**What is the conversion factor for inch to mile?**

A value in inch when **divided** by 63360 gives a value in mile.**What is the conversion factor for second to hour?**

A value in second when **divided** by 3600 gives a value in hour.

Given, the speed of Caroline in inches per second = 9 1/2 = 9.5/1 - (i)

Therefore following above literature and **dividing numerator by 63360 **and **denominator by 3600**, we get the speed in **miles per second**.

Thus, required speed = [9.5/63360]/[1/3600) = 0.539 = 0.5

She starts with $100 and plans to add $50 each week. write an equation she can use to calculate the amount of money she will have after any number of weeks. how much money will she have after 1 year?

**Main Answer:**

2700 dollars

**Explanation:**

Let x be the number of weeks and y be the total amount of money, then the equation can be written as,

[tex]y=50x+100[/tex] -------(1)

In a year there are 52 weeks.

Money she will have after 1 year is found out by putting x = 52 in the equation (1), we get

[tex]y=50(52)+100[/tex]

[tex]y=2600+100[/tex]

∴[tex]y=2700[/tex]

Therefore, the money she have after 1 year is 2700 dollars.

Mai biked 6\frac{3}{4} miles today, and Noah biked 4\frac{1}{2} miles.

How many times the length of Noah’s bike ride was Mai’s bike ride?

The **length** of Noah’s bike **ride** was 1 1/2 of Mai’s bike ride

From the question, the given parameters are

Distance covered by Mai = 6 3/4 milesDistance covered by Noah = 4 1/2 milesThe **number** of **times** the length of Noah’s bike ride was Mai’s bike ride is calculated as

Number of times = Distance covered by Mai/Distance covered by Noah

Substitute the known values in the above equation

So, we have the following equation

Number of times = (6 3/4)/(4 1/2)

Evaluate the **quotient** in the above equation

Number of times = 1 1/2

Hence. the **number** of **times** is 1 1/2 times

The perimeter of a pool is 116 feet. If the length of the pool is 3 times its width,

what is the width of the pool?

(Show work)

**Answer:**

**Answer:**

Perimeter = 2(l+b)

Perimeter = 116

width = x

length = 3x

116 = 2(3x+ x)

116 = 6x+2x

116 = 8x

x = 116/8

x = 14.5

You can verify answer by inputing value of x to see if perimeter is = 116 :

perimeter = 2(l+b)

116 = 2(3(14.5) + 14.5)

116 = 2(43.5 + 14.5)

116 = 87 + 29

in a 7 game series played with two teams, the first team to win a total of 4 games is the winner. suppose that each game played is independently won by team a with probability p

Each game played is **independently** won by team A with **probability **p, then team A will surely win the first game.

Given that one team leads 3 to 0, this would mean that in 3 trials, team A won all three games.

The **probability **of winning 3 out of 3 for team A is

P(A) = P3

The probability of winning 3 out of 3 for team B is

P(B) = (1-P)3

It is given that one of these two** scenarios** is the case, then the probability it is team A is:

P3/ (P3 + (1-P)3)

The probability that team A would win 0 of the next 4 games is

(1-P)4,

The total **number** of **employees** in the **company** in the year 2015 is 275 employees

**Number** of employees in the company **before** increase = 200 employees

**Percentage** increase in employees between 2005 and 2010 = 25%

**Percentage**: A percentage is a **ratio** or **fraction** where the full **value** is always 100. Sam, for instance, would have **received** 30 out of a **possible** 100 points if he had **received** 30% on his **arithmetic** test.

So, the **number** of employees **after** the **increase** = 200+25%of 200

Percentage **increase** in employees **between** 2010 and 2015 = 10%
