Write The Equation Of A Line That Is Parallel To The Line Whose Equation Is Y = 1/3x +6 And Passes Through (2024)

P = 2L + 2w

Length=

L = 2w + 6

New equation =

P = 2(2w + 6) + 2w

P = 4w + 12 + 2w

P = 12 + 6w

As stated in the question, the perimeter is 132 feet:

So,

132 = 12 + 6w

120 = 6w

W = 20

Now let’s find length using width:

L = 2w + 6

L = 2(20)+ 6

L = 40 + 6

Now we know that

W = 20
L = 46

The number of tiles required to cover the floor is 2880 tiles.

What is the number of Tiles Needed?

To solve this problem, we can find the number of tiles by calculating the area of a rectangle:

We have to convert the dimensions from feet to inches will be

1 feet = 12 inches

12 feet = 12 * 12 = 144in

15 feet = 12 * 15 = 180in

The area of the rectangle can be calculated as:

A = l * w

A = 180 * 144

A = 25920in²

The tiles are 9 squared inches, we can divide the area by 9 to find the number of tiles needed:

25920/9= 2880

Hence, The number of tiles needed will be 2880 tiles

The coefficient of the GCF of a set of algebraic terms, wil be the GCF of the coefficients of the terms.

Notice that the coefficients in this case, are 30 and 60.

The greatest comon factor of this set, is 30, since:

[tex]\begin{gathered} 30=30\cdot1 \\ 60=30\cdot2 \end{gathered}[/tex]

On the other hand, the variable x appears with an exponent of 5 in one case and an exponent of 3 in the other case. The greatest common factor for the variable x will be the lowest power, in this case, 3. Notice that:

[tex]\begin{gathered} x^3=x^3\cdot1 \\ x^5=x^3\cdot x^2 \end{gathered}[/tex]

Then, we can factor out the following:

Given:

The length of each ribbon is 25 cm.

The number of ribbon need by mother is 6.

Explanation:

Determine the length of ribbon for daughter's hair.

[tex]\begin{gathered} 25\cdot6=150\text{ cm} \\ =1.5\text{ m} \end{gathered}[/tex]

Since length is in decimal so we need to find multiple of 25 such that it is more than 150 and multiple of 100.

The multiples of 25 are 25,50, 75, 100, 125, 150, 175, 200, ...

Since 200 is more than 150 and multiple of 100 also.

Determine the length of 200 cm in terms of meters.

[tex]200\text{ cm}\cdot\frac{1\text{ m}}{100\text{ cm}}=2\text{ m}[/tex]

Answer:

4.6

Explanation:

The diagram shown is a right triangle having the following sides;

Opposite = 17

Adjacent = x

Angle of elevation = 75 degrees

Using SOH CAH TOA identity

Tan theta = opposite/adjacent

Tan 75 = 17/x

x = 17/tan 75

x = 17/3.73205

x = 4.6

Hence the value of x to the nearest tenth is 4.6

Solution

For this case we have the following random variable:

X= amount spend on average for groceries by one person

And we have the following properties:

mean= 52

sd= 14

The distribution of the variable is normal

We can find the middle 50% using a graph like this one:

We can find two quantiles from the normal distribution that accumulates 25% of the area on each tail of the distribution and we have:

Z= -0.674 and 0.674

Now we can use the z score formula given by:

[tex]z=\frac{x-\mu}{\sigma},x=\mu\pm z\cdot\sigma[/tex]

So then we have:

Minimum= 52 - 0.674*14 = 42.56

Minimum= 52 + 0.674*14 = 61.44

We are given the following function

[tex]f(t)=\frac{2t}{3}[/tex]

We are asked to find out the value of t which results in f(t) = 64

Let us substitute f(t) = 64 into the above function and solve for t

[tex]\begin{gathered} f(t)=\frac{2t}{3} \\ 64=\frac{2t}{3} \\ 3\cdot64=2t \\ 192=2t \\ \frac{192}{2}=t \\ 96=t \\ t=96 \end{gathered}[/tex]

Therefore, the value of t is 96

So, we are writing a function. c(x) is the manufacturing costs, and x is the amount of bikes manufactured. The y-intercept is 1908 because when no bikes are manufactured it still costs 1908 to run the factory. The slope is 75 because it costs $75 to create a bike. So, y = mx + b, where m is the slope and b is the y-intercept is:

c(x) = 75x + 1908

Answer:

Since one line is vertical, and one line is horizontal, the lines are perpendicular.

Step-by-step explanation:

The product of the slopes of perpendicular lines is -1.

We find the slopes of the 2 lines and multiply them together.

If the product equals -1, then the lines are perpendicular.

To find the slopes of the lines, we write each equation in the y = mx + b form, where m is the slope. In other words, we solve each equation for y.

3x + y = 7 + y

Subtract y from both sides.

3x = 7

x = 7/3

This is not the y = mx + b form since there is no y in the equation. A line with equation x = k, where k is a number, is a vertical line that passes through the point (k, 0), and the x-coordinate of all points on the line is k.

3(x + y) = 2 + 3x

3x + 3y = 2 + 3x

Subtract 3x from both sides.

3y = 2

y = 2/3

y = 0x + 2/3

Slope = m = 0

A line with 0 slope is a horizontal line.

Since one line is vertical, and one line is horizontal, the lines are perpendicular.

She made an initial deposit that we will call "D", as it is one of the unknowns.

We know that she made a weekly deposit (lets call this amount "w").

After 4 weeks she had $450 in the account balance and this is the sum of the initial deposit and 4 weekly deposits, so we can write:

[tex]D+4w=450[/tex]

At the ninth week she had $825, that correspond to the initial deposit and 9 weekly deposits. This can be written as:

[tex]D+9w=825[/tex]

We have a system of linear equations that we will solve by elimination: we will substract the first equation from the second and then find w.

[tex]\begin{gathered} (D+9w)-(D+4w)=825-450 \\ 5w=375 \\ w=\frac{375}{5} \\ w=75 \end{gathered}[/tex]

Now that we know "w", we can calculate D with any of the two equations:

[tex]\begin{gathered} D+4w=450 \\ D+4\cdot75=450 \\ D+300=450 \\ D=450-300 \\ D=150 \end{gathered}[/tex]

ANSWER

EXPLANATION

Let the length of the rectangle be L.

Let the width of the rectangle be w.

The length of the rectangle is 3 more than twice the width.

This means that:

L = 3 + (2 * w)

L = 2w + 3

The perimeter of a rectangle is given as:

P = 2w + 2L

The perimeter of the rectangle is 96 inches. This means that:

96 = 2L + 2w

Recall that: L = 2w + 3

=> 96 = 2(w) + 2(2w + 3)

=> 2(w) + 2(2w + 3) = 96

2m(-4.2m)

-4.2[tex]m^{2}[/tex] + - (4.2[tex]m^{2}[/tex])

-8.4[tex]m^{2}[/tex]

Step-by-step explanation:

2m(-4.2m) = -8.4 [tex]m^{2}[/tex]

-4.2 [tex]m^{2}[/tex] + (-4.2 [tex]m^{2}[/tex]) = 8.4[tex]m^{2}[/tex]

When having an ordered pair, we say they are in direct variation if the quotient:

[tex]\frac{y}{x}[/tex]

is constant. For case 1 we have:

[tex]\frac{80}{32}=\frac{100}{x}[/tex]

we can solve for "x" by multiplying by "x" on both sides:

[tex]\frac{x80}{32}=100[/tex]

Now we multiply by 32/80 on both sides:

[tex]x=\frac{100\times32}{80}[/tex]

Solving the operations we get:

[tex]x=40[/tex]

For case 2 we have:

[tex]-\frac{7}{-28}=\frac{y}{20}[/tex]

Now we solve for "y" by multiplying by 20 on both sides:

[tex]\frac{-7\times20}{-28}=y[/tex]

Solving the operations:

[tex]y=5[/tex]

ANSWER

T = 4x + 25;

T = $37

EXPLANATION

Let the number of special exhibits to be visited be x.

The cost of the musuem entrance ticket is $25 and each special exhibit costs an additional $4.

This means that the cost of cisiting x additional exhibits is:

4 * x = $4x

Therefore, the total cost to enter the musuem and visit any number of special exhibits is:

T = 4x + 25

That is the expression that represents the total cost.

If a person wants to visit three exhibits, it means that:

x = 3

Therefore, the total cost, T, is:

T = 4(3) + 25

T = 12 + 25

T = $37

That is the total cost to enter and visit three exhibits.

To find the standard deviation of this set of numbers, we will use the formula

[tex]s=\sqrt{\frac{\sum_^(x-\text{ }x_{mean})^2\text{ }}{n-1}}[/tex]

let us explain the parts of this formula, as follows:

[tex]x_{mean}\text{ is the mean of the data \lparen we have to calculate\rparen}[/tex][tex]n\text{ is the total quantity of numbers \lparen in this example 7\rparen}[/tex]

We will proceed by parts, the first thing to do is find the mean of the data

Calculating the mean

To find the mean, we will sum all the numbers and divide by the total quantity of numbers, as follows:

[tex]x_{mean}=\frac{\Sigma x}{n}=\frac{38+47+43+44+44+41+44}{7}=\frac{301}{7}=43[/tex]

That is, the mean of the set is 43. Now we proceed to find the difference between the data and the mean, and the add them to the power of two, in symbols we have:

[tex]\begin{gathered} \Sigma(x-x_{mean})^2=(38-43)^2+(47-43)^2+(43-43)^2+3\times\text{ }(44-43)^2+(41-43)^2 \\ \text{ =\lparen-5\rparen}^2+4^2+0^2+3\times\text{ }1^2+(-2)^2 \\ =25+16+3+4 \\ =48 \end{gathered}[/tex]

Now we introduce this result into the formula for the standard deviation, we find:

[tex]s=\sqrt{\frac{\Sigma(x-x_{mean})^2}{n-1}}=\sqrt{\frac{48}{7-1}}=\sqrt{\frac{48}{6}}=\sqrt{8}\approx\text{ 2.8}[/tex]

That is, after approximate to the nearest tenth, we found that the standard deviation of the set of numbers is 2.8
