Answer:

She is wrong and the correct answer is [tex]\frac{5}{21}[/tex].

Step-by-step explanation:

The given expression is

[tex]\frac{4}{7}-\frac{1}{3}[/tex]

Sandra says that [tex]\frac{4}{7}-\frac{1}{3}=\frac{3}{4}[/tex] because all you have to do is subtract the numerators and subtract the denominators.

She is wrong. The correct method is shown below.

Make the denominator common.

[tex]\frac{4\times 3}{7\times 3}-\frac{1\times 7}{3\times 7}[/tex]

[tex]\frac{12}{21}-\frac{7}{21}[/tex]

On further simplification we get

[tex]\frac{12-7}{21}[/tex]

[tex]\frac{5}{21}[/tex]

Therefore, the correct answer is [tex]\frac{5}{21}[/tex].

Step-by-step explanation:

To solve this system of equations, you can use either substitution or elimination. Let's use the elimination method.

First, multiply the second equation by 4 to make the coefficients of \( x \) in both equations opposites:

\( (2x + 5y) \times 4 = -28 \times 4 \)

This gives us:

\( 8x + 20y = -112 \)

Now, we'll subtract the first equation from this modified second equation:

\( (8x + 20y) - (-8x + 15y) = -112 - (-28) \)

Simplify:

\( 8x + 20y + 8x - 15y = -112 + 28 \)

\( 16x + 5y = -84 \)

Now we have a new equation:

\( 16x + 5y = -84 \)

And the first equation remains the same:

\( -8x + 15y = -28 \)

Now, we can solve this system of equations by elimination or substitution. Let's continue with elimination. Multiply the first equation by 2:

\( -16x + 30y = -56 \)

Now, add this equation to the second modified equation:

\( (-16x + 30y) + (16x + 5y) = -56 - 84 \)

\( 30y + 5y = -140 \)

\( 35y = -140 \)

Divide both sides by 35:

\( y = -4 \)

Now, substitute \( y = -4 \) into one of the original equations to solve for \( x \). Let's use the first equation:

\( -8x + 15(-4) = -28 \)

\( -8x - 60 = -28 \)

Add 60 to both sides:

\( -8x = -28 + 60 \)

\( -8x = 32 \)

Divide both sides by -8:

\( x = -4 \)

So, the solution to the system of equations is \( x = -4 \) and \( y = -4 \).

Step-by-step explanation:

The number 86.7 is a rational number. It is possible to obtain the number 86.7 by dividing the integer 867 by the integer 10, as in 867/10. Because 86.7 is a quotient that results when two integers are divided, we say that 86.7 is a rational number.

Answer:

The possible values of the number of hours clearing tables are 2 , 3 , 4 , 5 hours

Step-by-step explanation:

* Lets explain how to solve the problem

- Madelyn is making $20 per hour life guarding

- She is making $12 per hour clearing tables

- She can work no more than 13 total hours

∴ The greatest time she can work is 13 hours (≤)

- She must earn no less than $180

∴ The least money she wants to earn is $180 (≥)

- If Madelyn worked 8 hours life guarding and assume that she

 worked x hours clearing tables

∵ She can work no more than 13 hours

∴ 8 + x ≤ 13

- Subtract 8 from both sides

∴ x ≤ 5 ⇒ (1)

∵ She must earn no less than $180

∴ 8 × 20 + x × 12 ≥ 180

∴ 160 + 12x ≥ 180

- Subtract 60 from both sides

∴ 12x ≥ 20 ⇒ (2)

- From equation (1) ⇒ x = 1 , 2 , 3 , 4 , 5

- Substitute x in equation (2) by these values to find the right values

 of x

# If x = 1

∴ 12(1) ≥ 20

- But 12 is less than 20

∴ x can not be 1

# x = 2

∴ 12(2) ≥ 20

∴ 24 ≥ 20

- 24 is greater than 20 then x can be 2

∵ 3 , 4 , 5 greater than 2

∴ All of them give answers greater than 20

∴ x can be 3 , 4, 5

∵ x represents the number of hours for clearing tables

∴ The possible values of the number of hours clearing tables are

   2 , 3 , 4 , 5 hours

Madelyn can work 2, 3, 4, or 5 hours clearing tables to meet her requirements. This ensures she earns at least $180 while working no more than 13 total hours. The calculations consider her earnings from both jobs and time constraints.

Let's determine the possible values for the number of hours Madelyn must work clearing tables to meet her requirements. We know the following:

First, calculate the earnings from lifeguarding:

Now, let x be the number of hours she works clearing tables. To meet the requirement of earning no less than $180, we set up the following inequality:

Subtract 160 from both sides:

Divide both sides by 12:

Which simplifies to:

Since x must be a whole number, the minimum value for x is 2. Now, considering the total hours she can work (no more than 13), calculate the maximum value for x:

This gives us:

Subtract 8 from both sides:

So, the possible values for the number of hours she could work clearing tables are:

Answer:

r = q -6

Step-by-step explanation:

q= [tex]\frac{q}{r} -6[/tex]

[tex]\frac{\frac{q}{r} -6}{r}[/tex]

You do kcf (keep it, change it, flip it)

[tex]\frac{q}{r} -6 times \frac{r}{1}[/tex]

To solve the equation q/r - 6 = q for r, you need to isolate the variable r on one side of the equation.

To solve the equation q/r - 6 = q for r, we need to isolate the variable r on one side of the equation. First, we'll get rid of the fraction by multiplying both sides of the equation by r. This gives us r(q/r) - 6r = qr. Simplifying further, we have q - 6r = qr. Next, we'll move all the terms involving r to one side by subtracting qr from both sides of the equation. This gives us q - qr - 6r = 0. Factoring out the common factor of r from the last two terms, we have q - r(q + 6) = 0. Finally, we solve for r by dividing both sides of the equation by q + 6. So, the solution to the equation is r = q/(q + 6).

Answer:

14 units greater.

Step-by-step explanation:

Subtracting:

n + 3 - (n - 11)

= n - n + 3 + 11

= 14.

If we subtract n-11 from n+3 then we found n+3 is greater from n-11  by 14.

In mathematics difference means the difference in values means which value is how much greater than or less than from other.

We have to find how much is n+3 greater than n-11.

We have just subtract n-11 from n+3

=n+3-(n-11)

=n+3-n+11

=14

Hence n+3 is 14 number greater than n-11.

Answer:

Pythagorean theorem:

14.03 ft

Step-by-step explanation:

The height of the building is 315 feet because the ratio of the building's height to the post's height is equal to the ratio of the building's shadow length to the post's shadow length.

This problem can be solved using the concept of proportionality.

The height of the building is proportional to the length of its shadow, and the height of the post is proportional to the length of its shadow.

Express this mathematically as follows:

Building height / Post height = Shadow length / Post shadow length

Substituting the known values:

Building height / 3 feet = 105 feet / 4 inches

Convert 105 feet to inches first. 105 feet is equal to 105 × 12 = 1260 inches.

Rewrite the equation as follows:

Building height / 3 feet = 1260 inches / 4 inches

The units cancel out, and are left with:

Building height = 1260 / 4 = 315 feet

Therefore, the height of the building is 315 feet.

Final answer:

To calculate the building's height, we set up a proportion using similar triangles. With the shadow of the building being 105 feet and the shadow of a 3-foot post being 4 inches (1/3 feet), we solve the proportion to find that the building is 315 feet tall.

Explanation:

To determine the height of the building, we can use similar triangles. The method involves setting up a proportion based on the principle that similar triangles have corresponding sides that are in the same ratio. Given the length of the building's shadow and the length of the shadow cast by a known post, we can find the building's height.

Let's define the following variables: B for the height of the building, Sb for the length of the building's shadow, P for the height of the post, and Sp for the length of the post's shadow. From the problem, Sb = 105 feet, P = 3 feet, and Sp = 4 inches, which is 1/3 feet since there are 12 inches in a foot.

Using these variables, the proportion can be set up as follows:

Plugging in the known values, we get:

By solving this proportion for B, we find that:

Therefore, the height of the building is 315 feet.

Rate as Brainliest plz

Answer:

A. x<7

Step-by-step explanation:

We know three things:

Now we want to know how many more days the facility can continue to take in cats if none of their cats get adopted.

First, we want to know how many cats until the facility exceeds the occupancy and to do it we have to subtract the occupancy minus the cats they already have:

200 - 172 = 28

With this answer, we know that if they get 28 more cats they will have 200 cats and the occupancy has to be below 200.

Now we want to know how many days will it take them to get 28 more cats:

We know that every day they get 4 cats, so we are going to divide the number of cats to get 200 by the number of cats they get every day:

28(cats) / 4(cats per day) = 7 days

So in 7 days, they will pass their occupancy, which means that they can only take cats less than 7 days.

The expression will be:

x < 7

Where:

x is how many more days they can take in cats

That is a quadratic equation.

It can be solved by using the quadratic formula:

b = -4 and c = -8

x = (--4 +- sqr root (-4^2 - 4 * -3 * -8)) / (2 * -3)

x = (4 +- sqr root (16 -96)) / -6

x = 4 +- sqr root (-80) / -6

x1 = (4 +8.94427191 * i)  / -6
