A square floor has a side length of 7x^5y^6 units Square tile has a side length of x^2y units. how many tiles will it take to cover the floor

Answers

Answer 1

49x⁶y¹⁰ tiles are required to cover the floor;

Side length of the square floor = 7x⁵y⁶;

Side length of the square tile = x²y;

Area of the given floor is = (7x⁵y⁶)²  sq units

                                          = 7²x¹⁰y¹² sq units

                                          = 49x¹⁰y¹² sq units.

Area of a tile is = (x²y)² sq units

                         = x⁴y² sq units.

Let no. of tiles required be 'n';

Area of square floor = (No. of square tiles) × (Area of 1 square tile);

49x¹⁰y¹² = n × x⁴y²;

 n = 49x⁶y¹⁰;

Find the total amount given the original price and tax rate. round to the nearest hundredth if necessary. original price: $123.28 tax rate: 7.5% enter the correct answer in the box.

Answers

The Total amount to pay including the tax will be $132.52

In the given question, For the Total amount, we know that we have to add the Tax rate to the Principal amount. It is mentioned that the Principal amount P = $123.28 and the Tax rate is 7.5%. Firstly we have to calculate what amount of interest is to be charged upon the Principal amount. To calculate Interest we have the formula :

=>  I = (P * R)/100 , where I = Interest, P = Principal Amt, R = Interest Rate

=>  I = (123.28 * 7.5)/100   => I = 9.24

We get Interest amount = $9.24

To calculate the Total amount, We have the formula: T = P + I

where, T = Total Amount, P = Principal Amount, and I = Interest Amount

=>  T = 123.28 + 9.24  => T = 132.52

Hence, the Total Amount is $132.52

question 4 suppose the fraction of high school students who can drive is 15% and the fraction of college students who can drive is 23%. if one-fifth of the students are college students and the rest are high school students, what is the probability that a student who can drive is a college student? select the correct probability.

Answers

The probability that a student who can drive is a college student is 0.2771 or 27.7%

It will be sooved using Baye's theorem -

P(college) = P(C) / 1/5 = 0.2

P(high school students) = P(H) = 4/5 = 0.8

P(college drives) = 0.23

P(high school drives) = 0.15

We have to find, probability that a student who drives is a college student.

That is, we have to find P(C/D).

P(C/D) = P(C ∩ S)/P(S)

Since P(C ∩ S) is an independent event.

P(C ∩ S) = P(C) × P(S)

P(C ∩ S) = 0.2 × 0.23

= 0.046

Using bayes's theorem, we will get

P(C/D) = 0.2771 or 27.7%

The solution to the system of equations is (-7, 5)

What are linear equations?

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the solution to the system?

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

2x + y = -9

3x + 5y = 4

Make y the subject in 2x + y = -9

So, we have

y = -2x - 9

Substitute y = -2x - 9 in 3x + 5y = 4

So, we have

3x + 5(-2x - 9) = 4

Open the bracket

So, we have

3x - 10x - 45 = 4

Evaluate the like terms

-7x = 49

Divide both sides by -7

x  = -7

Substitute x  = -7 in y = -2x - 9

y = -2(-7) - 9

Evaluate

y = 5

Hence, the solution to the system of equations is (-7, 5)

If m< EBC = 3y+10 and m< ABE = 2y-20, find m< EBF.

Answers

By using the fact that EBC and ABE are supplementary angles, we will see that the measure of angle EBF is 106 degrees.

How to find the measure of the angle EBF?

First, we can notice that angles EBC and ABE are supplementary angles, which means that their measures add up to 180°.

Then we can write:

m∠EBC + m∠ABE = 180°

Replacing what we know we get:

3y + 10 + 2y - 20 = 180°

Now we can solve this linear equation for y, we will get:

5y - 10 = 180

5y = 180 + 10

y = 190/5 = 38

Then we have that:

EBC = 3*38 + 10 = 124°

ABE = 2*38 - 20 = 56°

Now, in the image it says that:

ABE = 2b = 56°

then b = 56°/2 = 28°

And ABF = 7b - 24 = 162°

Then:

EBF = ABF - ABE = 162° - 56° = 106°

We conclude that the measure of angle EBF is 106 degrees.

The simplification of the expression ∛(1/16) × (-54/1) is -27√4/32.

What is defined as the Rationalization?

Rationalization is the process of removing a radical as well as imaginary number from of the denominator of an arithmetic fraction. That is, in a fraction, remove the radicals so that the denominator just includes a rational number.

Step 1: Multiply the numerator and denominator by the a radical that removes the radical from the denominator.Step 2: Ensure that all radicals have been simplified.Step 3: If necessary, simplify the fraction.

Now the expression is given as;

= ∛(1/16) × (-54/1)

= -54/ ∛16

Taking cube root of 16.

= -54/(4√4)

= -27/2(√4)

By the process of rationalization, multiply the numerator and denominator by the a radical that removes the radical from the denominator which is √4.

= -27×√4/2(√4×√4)

Answers

The water in the rectangular pool which has a depth of 3/4 of the pool's depth has a volume of 2250 cubic feet.

If the depth of the water is 3/4 of the depth of the pool and the depth of the pool is 60 inches, then

depth of the water = 3/4 of the depth of the pool

depth of the water = 3/4(60 inches)

depth of the water = 45 inches = 3.75 feet

Volume is defined as the amount of space any object occupies. The volume for a rectangular prism is given by the formula:

V = lwh

l is the length

w is the width

Since the water occupies the inside of the rectangular pool, to solve the volume of the water, use the formula for the volume of a rectangular prism.

Statement a : "The standard deviation measures the variation of the data. If the standard deviation is 0, then there is some variation, so all the data are different" is false.

Statement b : "All the data must be equal to the mean because the sum of the squares of the differences of the data from the mean is 0. So, all the data take the same value" is true

What is standard deviation?

This is a term in statistics that represent the amount of variation in a data set or simply put the spread of the data set. Standard deviation is solved from the mean of the data, that is we get mean first before solving for standard deviation.

From the definition, if all the data is the same then the data should be equal to the mean. If the data is equal to the mean there will be no spread or variation leading to a zero standard deviation.
