Answer:

x = 2

Step-by-step explanation:

To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.

The formula for the perimeter of a rectangle is as follows:

P = 2L + 2W

Where P is the perimeter, L is the length, and W is the width.

Let L = 7x + 5 and W = x - 3

Now, we will simply plug our values into the formula and solve for x.

P = 2L + 2W

36 = 2 ( 7x + 5 ) + 2 ( x - 3 )

36 = 14x + 10 + 2x + -6

36 = 16x + 4

32 = 16x

2 = x

Thus, we have found the value of x to be 2.

Answer: [tex]h=\frac{2A}{(a+b)}[/tex]

Step-by-step explanation:

To solve for h, we want to get h alone. We need to use our algebraic properties.

[tex]A=\frac{1}{2} h(a+b)[/tex]                             [multiply both sides by 2]

[tex]2A=h(a+b)[/tex]                              [divide both sides by (a+b)]

[tex]h=\frac{2A}{(a+b)}[/tex]

Now that we have h alone, we know that [tex]h=\frac{2A}{(a+b)}[/tex].

Answer:

perimeter of the square is 32 inches

which agrees with the last answer in your list of options.

Step-by-step explanation:

Notice that the radius of the circle is exactly half of the side of the square, therefore, each side of the square must be 8 inches long.

Then, the perimeter of the square (addition of its four sides) is :

4 x 8 inches = 32 inches

Answer:

0.89

Step-by-step explanation:

Nunber of samples = 100

City mpg :

Mean = 28

Standard deviation =9.2

Highway mpg:

Mean = 35

Standard deviation = 8.6

correlation Coefficient (r) between city mpg and highway mpg = 0.95.

The value of the slope of the regression line that predicts highway mpg based on city mpg can be obtained by:

(Standard deviation of highway mgp / standard deviation of city mpg) × correlation Coefficient

Slope = (8.6 / 9.2) × 0.95

Slope = (0.934782 × 0.95) = 0.8880

Slope = 0.89 ( two decimal place)

Answer:

Net gain = 12 years(point)

Step-by-step explanation:

The Lions football team gained 20 yards after having lost 8 yearson the previous play.

Years(point) gained= 20

Years(point) loss= 8

The net gain for the two plays

Net gain = gain - loss

Net gain = 20-8

Net gain = 12 years(point)

Answer:

We need to solve this equation:

[tex]\frac{10}{4x}-3=2[/tex]

We pass -3 to the right summing:

[tex]\frac{10}{4x} = 2 + 3[/tex]

[tex]\frac{10}{4x}=5[/tex]

We pass the 4x that is dividing to the right multiplying:

[tex]10 = 5*4x[/tex]

[tex]10=20x[/tex]

We pass the 20 of the right to the left dividing:

[tex]\frac{10}{20}=x[/tex]

[tex]x=\frac{1}{2}[/tex]

Now, we know [tex]x=\frac{1}{2}[/tex], so we can verify:

[tex]\frac{10}{4*\frac{1}{2}}-3 = 2[/tex]

[tex]\frac{10}{2}-3=2[/tex]

[tex]5 - 3 = 2[/tex] TRUE

Answer:

(See explanation below for further details)

Step-by-step explanation:

A. What details can you determine about the dive from the coordinates of the point (5, -8)?

First component corresponds to time and second component to depth with respect to sea level. The diver is 8 feet below sea level at 5 seconds.

B. What is the average speed of the diver in the water? How can you tell from the graph?

The average speed of the diver ([tex]\bar v[/tex]), measured in feet per second, can be calculated by the following expression:

[tex]\bar v = \frac{x_{f}-x_{o}}{t_{f}-t_{o}}[/tex]

Where:

[tex]x_{o}[/tex], [tex]x_{f}[/tex] - Initial and final depth of diver, measured in feet.

[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in seconds.

There are three different average speeds: (i) Descent ([tex]t = 1\,s[/tex] to [tex]t = 5\,s[/tex]), (ii) Ascent ([tex]t = 5\,s[/tex] to [tex]t = 9\,s[/tex]), (iii) Descent + Ascent ([tex]t = 1\,s[/tex] to [tex]t = 9\,s[/tex])

(i) Descent ([tex]t = 1\,s[/tex] to [tex]t = 5\,s[/tex])

[tex]x_{o} = 0\,ft[/tex] and [tex]x_{f} = -8\,ft[/tex]

[tex]\bar v_{i} = \frac{-8\,ft-0\,ft}{5\,s-1\,s}[/tex]

[tex]\bar v_{i} = -2\,\frac{ft}{s}[/tex]

(ii) Ascent ([tex]t = 5\,s[/tex] to [tex]t = 9\,s[/tex])

[tex]x_{o} = -8\,ft[/tex] and [tex]x_{f} = 0\,ft[/tex]

[tex]\bar v_{ii} = \frac{0\,ft-(-8\,ft)}{9\,s-5\,s}[/tex]

[tex]\bar v_{ii} = 2\,\frac{ft}{s}[/tex]

(iii) Descent + Ascent ([tex]t = 1\,s[/tex] to [tex]t = 9\,s[/tex])

[tex]x_{o} = 0\,ft[/tex] and [tex]x_{f} = 0\,ft[/tex]

[tex]\bar v_{iii} = \frac{0\,ft-0\,ft}{9\,s-1\,s}[/tex]

[tex]\bar v_{iii} = 0\,\frac{ft}{s}[/tex]

C. Which point on the graph shows the starting location of the diver?

The initial location is when [tex]t = 0\,s[/tex], which corresponds to the intercept of the line on y-axis.

Answer:

720ways

Step-by-step explanation:

DALLAS = 6!

6x 5 x 4 x 3 x 2 x 1

720 ways

The letters of the word DALLAS can be arranged in 720 distinct ways.

Multiplication is the mathematical operation that is used to determine the product of two or more numbdistinctn event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

A word has n letters. then there are m repeating letters, each of them repeating r0, r1, r2.. times

So the number of distincts ways the letters DALLAS can be arranged are:

DALLAS = 6!

= 6x 5 x 4 x 3 x 2 x 1

= 720 ways

The letters of the word DALLAS can be arranged in 720 distinct ways.

Answer:

The distance formula is an algebraic expression used to determine the distance between two points with the coordinates (x1, y1) and (x2, y2).

Example

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates: HOPES THIS HELPS

• Answer:

p = 4

x = - 25

• Step-by-step explanation:

25p = 100

p = 100÷25

p = 4

35 = - 2x - 15

2x = - 35 - 15

2x = - 50

x = - 25

Answer:

1) P= 4    2) x = -25

Step-by-step explanation:

25p = 100

divide both sides by 25

p = 4

35 = -2x - 15

add 15 to both sides

50 = -2x

divide both sides by -2

x = -25

Answer:

y= -1/2x +5

Step-by-step explanation:

Answer: In five months,she will save the same money which is $250.

Step-by-step explanation:

Using the first statement we can generate the function y=10x + 200  and using the second statement we can also generate the function y = 30x + 100 . Now using the two equations solve for x and y to determine how many months they cost the same.

y = 10x + 200

y = 30x + 100  

Substitute the value of x in the first equation into the second equation.

30x + 100= 10x + 200   now solve for x

         -100            -100

30x = 10x + 100

-10x    -10x

20x = 100

x= 5  

This means in five months Tina will save the same amount. Now to find out how much the amount is, plot the value of x into one of the equations and solve for  y.

y = 10(5) + 200

y = 50 + 200

y = 250  

She will save $250 with either option.

Answer:

(0, -5) and (4, 3)

Step-by-step explanation:

I assume you're looking for the coordinates of the intersections, if any.

Solve by substitution:

x² + (2x − 5)² = 25

x² + 4x² − 20x + 25 = 25

5x² − 20x = 0

5x (x − 4) = 0

x = 0 or 4

So the coordinates are (0, -5) and (4, 3).

Answer:

Step-by-step explanation:

Answer: 21 years

Step-by-step explanation: After the first year, it’s down by 3 so 145. For the next 20 years, you go down 6 shrubs a year. At year 20 it will be 31 shrubs so at year 21 it will be at 25 shrubs.

Answer:

21 years.

Step-by-step explanation:

The first thing we do is subtract the 3 shrubs from the first year from the total 148.

148 - 3 = 145

We then take 29 from 145, as the supermarket wants less than 30 shrubs on their property, so the maximum amount they want to keep is actually 29.

145 - 29 = 116

The supermarket can pay to have 6 shrubs cut down every year, excluding the first, so we need to do then is divide 116 by 6.

116 ÷ 6 = 19.333.

Because that equation leaves us with a decimal, we have to round up to get a whole number because the answer has to be in years, not years and months.

19.333 rounded up is 20.

So that's 20 years of paying for 6/per year. We have to add on the one year they only payed for 3 shrubs to be cut down, making the answer;

We can further confirm we have the right answer by doing;

6 × 20 = 120

145 - 120 = 25

Because we're going down in 6's, we know that 20 is the lowest amount of years it would take to get less than 30 shrubs, because 25 + 6 = 31.
