The best representation of the number of tiles that will be needed to cover the Floor is 80 tiles.

The number of tiles needed to cover the floor, we can calculate the total area of the floor and divide it by the area of each tile.

The area of the floor is given by the product of its length and width: 15 feet * 12 feet = 180 square feet.

The area of each tile is given by the product of its length and width: 1.5 feet * 1.5 feet = 2.25 square feet.

To find the number of tiles needed, we divide the total area of the floor by the area of each tile:

Number of tiles = (Total area of the floor) / (Area of each tile) = 180 square feet / 2.25 square feet = 80 tiles.

therefore, the best representation of the number of tiles that will be needed to cover the floor is 80 tiles.

Answer:

[tex]\huge\boxed{\sf r = 5}[/tex]

Step-by-step explanation:

Given that,

7q + 35 = 7q + 7r

7q - 7q + 35 = 7q - 7q + 7r

35 = 7r

35/7 = r

5 = r

OR

[tex]\rule[225]{225}{2}[/tex]

Answer:

r = 5

Step-by-step explanation:

Given statement,

→ 7(q + 5) is equivalent to (q + r)7.

Forming the equation,

→ 7(q + 5) = 7(q + r)

Now we have to,

→ Find the required value of r.

Then the value of r will be,

→ 7(q + 5) = 7(q + r)

Applying Distributive property:

→ 7(q) + 7(5) = 7(q) + 7(r)

→ 7q + 35 = 7q + 7r

Cancelling 7q from both sides:

→ 35 = 7r

→ 7r = 35

Dividing the RHS with number 7:

→ r = 35/7

→ [ r = 5 ]

Therefore, the value of r is 5.

Answer:

Length of third side = 30 inches

Step-by-step explanation:

We will need a system of equations to find the length of the third side.

First equation:

We know the perimeter of a triangle is simply the sum of its sides.

Thus, since the perimeter is 45, our first equation is x + x + y = 45, which simplifies to 2x + y = 45.

Second equation:

Since we're told that the length of the third side is twice as long as the sum of the congruent sides, our second equation is y = 2(x + x), which simplifies to y = 2(2x) and then finally y = 4x

Method:  Substitution.

We can first solve for x (length of one of the congruent sides) by substituting y = 4x for y in 2x + y = 45:

2x + 4x = 45

6x = 45

x = 7.5

Find y:

Now we can find y (length of the third side) by plugging in 7.5 for x in y = 4x:

y = 4(7.5)

y = 30

Thus, the length of the third side is 30 inches.

Optional Step to check validity of answers.

First equation:  Check that the sum of 7.5, 7.5, and 30 = 45

7.5 + 7.5 + 30 = 45

15 + 30 = 45

45 = 45

Second equation:  Check that 30 is twice the sum of 7.5 + 7.5

30 = 2(7.5 + 7.5)

30 = 2(15)

30 = 30

Thus, our answers are correct and we've correctly determined the length of the third side of the triangle in inches.

Using the proportion principle , Orange Juice has a greater percentage of water than Apple juice

To determine which juice has a greater percent of water, we need to calculate the percentage of water in each juice.

Percentage of water = (Water content / Total content) * 100

Water content = 32 ounces

Total content = 80 ounces

Percentage of water in apple juice = (32 / 80) * 100 = 40%

Water content = 48 ounces

Total content = 64 ounces

Percentage of water in orange juice = (48 / 64) * 100 = 75%

Comparing the percentages, we can conclude that orange juice has a greater percentage of water (75%) than the apple juice (40%).

The two expressions that are less than 7/8 are 7/8 x 9/19 and 7/8 x 3/4.

To determine which expressions are less than 7/8, we can compare them individually to 7/8 and evaluate their values.

Let's consider each expression one by one:

7/8 x 9/19:

To compare this expression to 7/8, we multiply the fractions:

(7/8) x (9/19) = 63/152.

Since 63/152 is less than 7/8, this expression is less than 7/8.

7/8 x 3/4:

Multiplying the fractions:

(7/8) x (3/4) = 21/32.

Since 21/32 is less than 7/8, this expression is less than 7/8.

7/8 x 9/9:

The fraction 9/9 simplifies to 1, so the expression becomes:

(7/8) x 1 = 7/8.

Since 7/8 is equal to 7/8 (not less than), this expression is not less than 7/8.

7/8 x 4/3:

Multiplying the fractions:

(7/8) x (4/3) = 28/24.

We can simplify 28/24 to 7/6.

Since 7/6 is greater than 7/8, this expression is not less than 7/8.

Therefore, the two expressions that are less than 7/8 are 7/8 x 9/19 and 7/8 x 3/4.

Answer: 0.07

Step-by-step explanation:

To find the relative frequency of people in the sample whose place of residence is suburban and whose highest degree is a two-year degree, we need to calculate the ratio of the number of people with those characteristics to the total sample size.

Looking at the contingency table, we can see that the number of people in the suburban category with a two-year degree is 21.

The total sample size is given as 311.

Therefore, the relative frequency can be calculated as:

Relative frequency = (Number of people in suburban category with two-year degree) / (Total sample size)

= 21 / 311

≈ 0.0676

Rounded to two decimal places, the relative frequency is approximately 0.07.

The values of the variables are y = 102° and z = 23°.

Given that are two parallel lines j and m we need to find the measures of the variables y and z,

So,

Since, j║m, therefore, y and 78° are supplementary because they are exterior consecutive angles between two parallel lines,

So,

y + 78° = 180°

y = 180° - 78°

y = 102°

Now,

y and (4z-14) are linear pair angles, which means they are also supplementary.

Therefore,

y + (4z-14) = 180°

102° + 4z - 14 = 180°

4z + 88 = 180°

4z = 92°

z = 23°

Hence the values of the variables are y = 102° and z = 23°.

To compute the regression equation based on the given data, we can use the formulas for slope (b1) and y-intercept (bo):

b1 = (NΣXY - ΣXΣY) / [tex](N\sum X^2 - (\sum X)^2)[/tex]

bo = (ΣY - b1ΣX) / N

Where:

N = Number of data points (in this case, 11)

ΣX = Sum of all X values (prices)

ΣY = Sum of all Y values (average number of pounds sold per day)

ΣXY = Sum of the product of X and Y values

[tex]\sum X^2[/tex] = Sum of the squares of X values

Using the provided data:

Ex = 210

Xy = 450

Zcy = 10387

Zz = 7275

Xy = 42471

Let's calculate the required values:

N = 11

ΣX = Ex + Zcy + Zz = 210 + 10387 + 7275 = 17872

ΣY = Xy = 450

ΣXY = Xy = 450

[tex]\sum X^2 = (Ex)^2 + (Zcy)^2 + (Zz)^2 = (210)^2 + (10387)^2 + (7275)^2 = 239208144[/tex]

Answer:

The change in volume is -5.5 mL (a decrease in volume of 5.5 mL) when 60.0 mL of gas is cooled from 33.0°C to 5.00°C.

Step-by-step explanation:

To calculate the change in volume, we need to use the ideal gas law equation:

V1/T1 = V2/T2

where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.

Given:

V1 = 60.0 mL

T1 = 33.0°C = 33.0 + 273.15 = 306.15 K

T2 = 5.00°C = 5.00 + 273.15 = 278.15 K

Now we can calculate V2, the final volume:

V1/T1 = V2/T2

(60.0 mL) / (306.15 K) = V2 / (278.15 K)

Cross-multiplying and solving for V2:

V2 = (60.0 mL) * (278.15 K) / (306.15 K)

V2 = 54.5 mL

The final volume, V2, is 54.5 mL.

To find the change in volume, we subtract the initial volume from the final volume:

Change in volume = V2 - V1

Change in volume = 54.5 mL - 60.0 mL

Change in volume = -5.5 mL

Therefore, the change in volume is -5.5 mL (a decrease in volume of 5.5 mL) when 60.0 mL of gas is cooled from 33.0°C to 5.00°C.
