A rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.

To determine how many square tiles can fit in a rectangular floor, we need to calculate the total number of tiles that can fit both horizontally and vertically.

Given:

Length of the rectangular floor = 14 ft

Width of the rectangular floor = 6 ft

Edge length of square tile = 3/4 ft

First, let's calculate the number of tiles that can fit horizontally:

Length of the rectangular floor / Edge length of square tile = 14 ft / (3/4 ft) = 14 ft × (4/3 ft) = 56/3 ft

Since we want a whole number of tiles, we need to round down or take the floor value:

Number of tiles horizontally = floor(56/3) = 18 tiles

Next, let's calculate the number of tiles that can fit vertically:

Width of the rectangular floor / Edge length of square tile = 6 ft / (3/4 ft) = 6 ft × (4/3 ft) = 24/3 ft

Again, we round down or take the floor value:

Number of tiles vertically = floor(24/3) = 8 tiles

To find the total number of tiles, we multiply the number of tiles horizontally by the number of tiles vertically:

Total number of tiles = Number of tiles horizontally × Number of tiles vertically = 18 tiles × 8 tiles = 144 tiles

Therefore, in a rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.

Mrs. Brown can assign 165 different homework sets to her Algebra 1 class.

We have,

The number of different homework sets Mrs. Brown could assign can be calculated using the combination formula.

In this case, she wants to choose 8 problems out of 11 available problems. The formula for combinations is given by:

C(n, r) = n! / (r! * (n - r)!)

Where n is the total number of items to choose from and r is the number of items to be chosen.

Using this formula:

C(11, 8) = 11! / (8! x (11 - 8)!)

C(11, 8) = 11! / (8! x 3!)

Simplifying the factorial expressions:

C(11, 8) = (11 x 10 x 9 x 8!) / (8! x 3 x 2 x 1)

The factorial terms cancel out:

C(11, 8) = (11 x 10 x 9) / (3 x 2 x 1)

C(11, 8) = 165

A) Two equations are,

S = 18 + 4t

L = 30 + 3t

Where, "t" represents the number of weeks that have passed.

B)  It will take 12 weeks for Samuel and Lewis to have the same number of rocks in their collections.

C) when the amount of rocks in their collection is equal, Samuel and Lewis will have 66 rocks each.

Part A:

For a system of equations to represent the number of rocks in each person's collection.

Let "S" be the number of rocks in Samuel's collection and "L" be the number of rocks in Lewis's collection.

Hence, We can represent the situation as follows:

Equation 1:

S = 18 + 4t

Equation 2:

L = 30 + 3t

Where, "t" represents the number of weeks that have passed.

Part B:

To find out how many weeks it will take for Samuel and Lewis to have the same number of rocks in their collections, we need to set Equation 1 equal to Equation 2 and solve for "t".

This gives us the following:

S = L

18 + 4t = 30 + 3t

1t = 12

t = 12 weeks

Hence, It will take 12 weeks for Samuel and Lewis to have the same number of rocks in their collections.

Part C:

For number of rocks Samuel and Lewis will have when the amount of rocks in their collection is equal, we can substitute the value of "t" that we found in Part B into either Equation 1 or Equation 2.

Hence, substituting "t = 12" into Equation 1 gives,

S = 18 + 4(12)

S = 18 + 48

S = 66 rocks

Therefore, when the amount of rocks in their collection is equal, Samuel and Lewis will have 66 rocks each.

It will take John approximately 2.69 hours to paint the room alone.

Let's denote the individual rates of John, Rick, and Molli as J, R, and M, respectively. We are given the following information:

John, Rick, and Molli can paint the room together in 5 hours.

Molli alone can paint the room in 14 hours.

Rick alone can paint the room in 10 hours.

To find the equation comparing the group rate to the sum of the individual rates, we can use the concept of work done. The amount of work required to paint the room is the same, regardless of who is doing the work.

The equation can be expressed as:

1/5 = 1/J + 1/R + 1/M

Now, let's substitute the given information into the equation. We know that:

M = 14 (since Molli can paint the room alone in 14 hours)

R = 10 (since Rick can paint the room alone in 10 hours)

Substituting these values, the equation becomes:

1/5 = 1/J + 1/10 + 1/14

To solve for J, we can find the least common denominator (LCD) of 10 and 14, which is 70:

14J + 7J + 5J = 70

26J = 70

J = 70/26

J ≈ 2.69

Answer:

50% ate uncle joe and 50% ate robert so, uncle joe make 14 cookies

Answer:

1. Michael ate 50% of the cookies, so the remaining cookies are 50% of the total. Let's denote the total number of cookies as T. So, after Michael ate his share, 0.5 x T cookies remained.

2. Robert then ate 50% of what was left, leaving only 50% of the cookies that were left after Michael ate. So, after Robert ate his share, 0.5 x 0.5 x T = 0.25 x T cookies remained.

3. We know that 14 cookies remained after Robert ate his share.

So, we can set up the equation 0.25 x T = 14 and solve for T:

T = 14/0.25 = 56

Susan uses 500 milliliters of solution b to obtain a resulting mixture with 102 milliliters of pure alcohol.

Let's set up the equation based on the given information.

Let x represent the amount of solution b in milliliters.

Since Susan uses 100 milliliters less of solution a than solution b, the amount of solution a is (x - 100) milliliters.

We know that solution a has a concentration of 13% alcohol, which means that for every 100 milliliters, it contains 13 milliliters of alcohol.

Similarly, solution b has a concentration of 10% alcohol, which means that for every 100 milliliters, it contains 10 milliliters of alcohol.

Given that the resulting mixture has 102 milliliters of pure alcohol, we can set up the equation:

0.13(x - 100) + 0.1x = 102

Simplifying the equation, we have:

0.13x - 13 + 0.1x = 102

0.23x - 13 = 102

0.23x = 115

x = 115 / 0.23

x = 500

Therefore, Susan uses 500 milliliters of solution b to obtain a resulting mixture with 102 milliliters of pure alcohol.

Based on the given data, the relationship appears to be exponential.

To determine if the relationship between the given values is linear, exponential, or neither, we can examine the pattern in the data.

If the relationship is linear, we would expect the values of y to increase or decrease at a constant rate as the values of x increase. In other words, there would be a constant slope between the points.

If the relationship is exponential, we would expect the values of y to change by a constant factor as the values of x increase. In this case, the relationship would exhibit exponential growth or decay.

Looking at the given values of x and y, we can observe the following differences between consecutive x-values: 7, 9, 9, 9. These differences are not constant, indicating that the relationship is not linear.

To determine if the relationship is exponential, we can examine the ratios between consecutive y-values: 5/10 = 0.5, 10/20 = 0.5, 20/40 = 0.5. These ratios are constant, suggesting that the relationship may be exponential with a common ratio of 0.5.

Answer:

approximately 4.2667%

Step-by-step explanation:

To calculate the percentage above the website's estimate that Jerrold set his asking price, we can use the following formula:

Percentage above = ((Asking price - Website estimate) / Website estimate) * 100

Percentage above = (($750,000 - $715,000) / $715,000) * 100

Percentage above ≈ 4.895

Therefore, Jerrold set his asking price approximately 4.895% above the website's estimate.

To calculate the percentage below his asking price that Jerrold sold for, we can use the following formula:

Percentage below = ((Selling price - Asking price) / Asking price) * 100

Percentage below = (($718,000 - $750,000) / $750,000) * 100

Percentage below ≈ -4.2667

Therefore, Jerrold sold his house approximately 4.2667% below his asking price.

A function f is said to be one-to-one, or injective, if it has the property that for any two different inputs, it produces two different outputs.

More formally, a function f: X -> Y is one-to-one (or injective) if for every x1, x2 in X, if x1 ≠ x2 then f(x1) ≠ f(x2).

This means that no two different elements of the domain X map to the same element of the codomain Y. If you were to draw a horizontal line through any point on the graph of a one-to-one function in the Cartesian plane, that line would intersect the graph at most one time.
