Darnell buys homes and flips them by completing renovations to turn a profit on his investment. He is currently working on a house with three bedrooms that need new hardwood floors. He is estimating the total cost to purchase hardwood flooring for the bedrooms with the following dimensions.

Bedroom 1: 22 feet by 15 feet
Bedroom 2: 15 feet by 12 feet
Bedroom 3: 13 feet by 12 feet
A big home improvement store advertises the price of two types of flooring, shown below.

$7.25 per square foot
$6.75 per square foot plus a $100 fixed installation fee
Which of these two prices would be best for Darnell to estimate the total cost of new hardwood flooring in the three bedrooms?

You can use the circumference of the circle that the blade makes to calculate the linear velocity at the end of the blade.

The linear velocity at the end of the blade is 13571.7 inches per minute

You can think of it as if some circle is being drawn by the end of the blade and then that circle is like wheel of a bicycle and its travelling on road. Each rotation will make it cover distance equal to its circumference. Since there are 60 revolutions of the blade in each minute, thus, 60 rounds of that wheel.

The total distance in 1 minute = 60 times circumference of the circle made by the end of the blade of the lawnmower.

Since the blade is 36 inches long, it can be taken as radius of that circle.

The circumference is thus calculated as [tex]2 \times \pi \times 36 = 226.19 \: \rm inches[/tex]

Thus, linear velocity = 226.19 times 60 inches per minute = 13571.7 inches per minute

Thus,

The linear velocity at the end of the blade is 13571.7 inches per minute

com loses 1/4 of its value after every year it is purchased

v = original price times 1/4 x times(x represents)

v = 800*(3/4)^x

so, if x is five, then t is

800*(3/4)^5= 189 27/32

Answer:

[tex]v=800(0.75)^t[/tex]

$189.84 (nearest cent)

Step-by-step explanation:

If a computer loses 1/4 of its value each year, then each year it will be 75% of the value of the previous year, since 100% - 25% = 75%.  

Therefore, we need to model this as an exponential function.

General form of an exponential function: [tex]y=ab^x[/tex]

where:

From the given information:

Substituting the values into the formula:

[tex]\implies v=800(0.75)^t[/tex]

When x = 5, t = 5

[tex]\implies v=800(0.75)^5=189.84375[/tex]

⇒ v = $189.84 (nearest cent)

Answer:

500 lbs of mixed nuts

Step-by-step explanation:

15.4% of mixed nuts = 77 lbs of pecans

Divide the weight of pecans by the percent of mixed nuts to find how many pounds of pecans equal 1% of the mixed nuts:

77 / 15.4 = 5,  so 5 lbs equals 1% of mixed nuts

Now multiply that number by 100 to get 100% of mixed nuts:

5 x 100 = 500

Therefore, there are 500 lbs of mixed nuts in a batch altogether.

To check, 15.4% = 15.4/100 = 0.514

Therefore, 15.4% of 500 = 0.514 x 500 = 77

Thereby proving that 15.4% of 500 is 77.

Answer:

360

Step-by-step explanation:

270 = 75% of x

270 = 0.75 × x

0.75x = 270

x = 270/0.75

x = 360

Answer: 360

Answer:

360

Step-by-step explanation:

We have, 75% × x = 270

or, 75/100 × x = 270

Multiplying both sides by 100 and dividing both sides by 75,

we have x = 270 × 100/75x = 360

If you are using a calculator, simply enter 270×100÷75, which will give you the answer.

Answer:

50 players

Step-by-step explanation:

Let x be the amount of players last year and y be the amount of players this year then...

y=3x+2

y=152

We can solve this using substitution. Substitute 152 for y:

y=3x+2

152=3x+2

Subtract 2 from both sides (subtraction property of equality)

152-2=3x+2-2

150=3x

Divide both sides by 3 (division property of equality)

x=50

There were 50 players last year.

I might not be able to solve it correctly but this might help a lot. Formula: V = πr 2 h

Step-by-step explanation:

Answer:

C. 8 is the correct answer.

Step-by-step explanation:

Let <DAB be x°

Now,

taking x as reference angle in triangle ADB,

cosx = b/h

or, cosx = 4/AB

Now,

again taking x as reference angle in triangle ACB,

cosx = b/h

or, cosx = AB/20

Now,

cosx = AB/20 = 4/AB

or, AB/20 = 4/AB

or, AB² = 80

Now,

Using pythagoras theorem in triangle ABD,

h² = p² + b²

or, AB² = BD² + AD²

or, 80 = BD² + 4²

or, 80 - 16 = BD²

so, BD² = 64

so, BD = 8

Step-by-step explanation:

3 is not a factor of 16.

Is that a valid answer? lol

Hi there!

First of all, let's determine the factors of 16.

Remember, a factor is a number that a number can be evenly divided by.

Example: 5 is a factor of 10, because 10 can be evenly divided by 5.

So, the factors of 16 are:

1, 2, 4, 8, and 16.

Now, there's an infinite amount of numbers that are not factors of 16. Here are some of them:

3, 5,7,9, 10,11, 12, 13, 14, 15...

Lets say its a cube with a length of 6, a width of 6, and a height of 6. I would find the base first by multiplying the width times length, which you probably know how to do.  The base would be 36, then I would multiply it by the height which is six which would be 216.

The A option is correct.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The interest rate applied to the present value has on the monthly payment P in the formula

[tex]\rm P = PV(\dfrac{i}{1-i})^{-n}[/tex]

The effect an increase in i.

[tex]\rm P = PV(\dfrac{i}{1-i})^{-n}\\[/tex]

on simplifying the equation, we get

[tex]\rm P = PV(\dfrac{i}{1-i})^{-n}\\\\P = PV\dfrac{1}{(\frac{i}{1-i})^n}\\\\\\P = PV(\dfrac{1-i}{i})^{n}\\\\P = PV(\dfrac{1}{i} - 1)^{n}[/tex]

Let n be the constant, then the equation will be

[tex]\rm P = PV(\dfrac{1}{i} - 1)^{n}\\\\\dfrac{1}{V} \propto \dfrac{1}{i}\\\\V \propto i[/tex]

It is clear that V is proportional to i.

An increase in i, the interest rate, will not change P, the monthly payment.

Thus, the A option is correct.
