Answer:

y = -2x + 5

Step-by-step explanation:

Slope-intercept form is writen like this; y = mx + b. Where m = slope and b = y-intercept.

We know the slope, so, find the y-intercept.

y = -2x + b

3 = -2(1) + b

3 = -2 + b

5 = b

Put everything we know/solved for into the original formula.

y = -2x + 5

Given:

Searches in February = 8972

There were 7,313 more searches in the library book checkout system in January than February.

To find:

The searches in both months.

Solution:

Searches in February = 8972

There were 7,313 more searches in the library book checkout system in January than February. So,

Searches in January = 8972 + 7313 = 16285

Now,

Total number of Searches in both months = January + February  searches

[tex]=16285 + 8972[/tex]

[tex]=25257[/tex]

Therefore, total number of searches in both months is 25257.

Answer:

Step-by-step explanation:

Step one:

total number of people surveyed= 1500

we are told that 300 people would buy that car again,

this implies that they like the car and are satisfied with it

Step two:

the percent of people satisfied can be computed as

=300/1500*100

=3/15*100

=1/5*100

=0.2*100

=20%

The people surveyed were satisfied with the​ car are 20%

Answer:

Step-by-step explanation:

If a shape has four sides, then it is a quadrilateral.

If a shape has four sides, then it is a quadrilateral so option (C) will be correct.

A quadrilateral is a geometrical 2d shape in which there are four sides and each side is connected and makes a close polygon.

In other meaning, a quadrilateral is a kind of polygon in which four sides for example rectangle, square, and parallelogram are quadrilateral.

a quadrilateral is a four-sided polygon, having four edges and four corners

A parallelogram is a basic quadrilateral with two sets of parallel sides.

The confronting or opposing sides and the opposing angles of a parallelogram are of equal length.

A quadrilateral is a quadrilateral because it has four sides not because it is quadrilateral so it has four sides.

For example, 4 sides are equal so the square is not due to the square all lines will same.

Hence If a shape has four sides, then it is a quadrilateral.

The circumference of the circle is 105 in to the nearest tenth.

The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.

The circumference of the circle = 2πr

We are given that the radius of a circle is 16.7 in.

We need to determine the circumference to the nearest tenth.

Radius r = 16.7

Then circumference of the circle = 2πr

= 2 x 3.14 x 16.7

= 104.87

Therefore, the circumference of the circle is 105.

Answer:

Step-by-step explanation:

For l laps around a 1/4 mile track, the total distance is ...

  l×(1/4)

After adding 2 1/2 miles to that, Gabriella's total distance was 4 miles:

  l×(1/4) +(2 1/2) = 4 . . . . an equation to find l

__

We can solve this equation by subtracting 2 1/2, then multiplying by 4.

  l×(1/4) = 1 1/2

  l = 4(1 1/2)

  l = 6

Gabriella ran 6 laps on the track.

Answer:

$181.9

Step-by-step explanation:

Si cuesta 85 dólares por 3 horas, queremos duplicarlo para obtener la cantidad por 6 horas, que es 170 dólares. Esto es antes del impuesto a las ventas. Puede encontrar la cantidad después del impuesto a las ventas multiplicando 170 por 1.07. Hace esto porque el 100 por ciento del costo sería 170 por 1 y el 7 por ciento es .07, por lo que si desea el 107 por ciento del costo, debe hacerlo 170 por 1.07. Esto funciona porque toma el 7 por ciento de 170 y lo agrega al costo total. También puede hacer esto 170 veces .07. Luego suma el producto a 170. 181,9 es la respuesta final.

English- If it costs 85 dollars for 3 hours we want to double that to get the amount for 6 hours which is 170 dollars. This is before sales tax. You can find the amount after sales tax by multiplying 170 by 1.07. You do this because 100 percent of the cost would be 170 times 1, and 7 percent is .07, so if you want 107 percent of the cost you want to do 170 times 1.07. This works because it takes 7 percent of 170 and adds it to the total cost. You could also do this by 170 times .07. Then add the product to 170. 181.9 is the final answer.

Answer:

We need to find the distance between the pairs of points to know which is greater than 6units. To do that we make use of this formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Where [tex](x_1 , y_1)[/tex] and [tex](x_2 , y_2)[/tex] are two points on the line.

Let us denote Creepy Carven with CC, Bernie Barn as BB, Sweet Symphonies as SS, Rock and Roll Hall as RR, Whimsical Wonders as WW, Mysterial Mansion as MM and Star Grazing point as SG.

The distance between CC (-2, 5) and BB(-3, 2) using that formula will be:

[tex]d = \sqrt{(-3 + 2 )^2 + (2 - 5)^2}[/tex]

Which is [tex]d = \sqrt{(-1 )^2 + (-3)^2}[/tex]

That gives

[tex]d = \sqrt{10} < 6[/tex]

If we do this for BB to SS we have our value greater than 6, SS to RR our value greater than 6, RR to WW greater than 6, WW to MM is equal to 6 and MM to SG is less than 6.

From here we conclude that the pairs of places greater than 6 is:

BB to SS

SS to RR

RR to WW

WW to MM

Answer:

First, plot each of the points and label them.

Determine the distance between the pairs of places listed in each answer choice.

Since Whimsical Wonders and Rock and Roll Hall lie on the same horizontal line, the distance between the two points is the absolute value of the difference of the x-coordinates.

Using this same process, the distance between Bernie's Barn and Mystery Mansion is 6 units, and the distance between Creepy Cavern and Star Gazing Point is 7 units.

Since the Mystery Mansion and Whimsical Wonders lie on the same vertical line, the distance between the two points is the absolute value of the difference of the y-coordinates.

Using this same process, the distance between Rock and Roll Hall and Creepy Cavern is 9 units, and the distance between Sweet Symphonies and Bernie's Barn is 3 units.

Therefore, the pairs of places that are more than 6 units from one another are Creepy Cavern and Star Gazing Point and Rock and Roll Hall and Creepy Cavern.

Answer:

2 outcomes

Step-by-step explanation

The Roslin has 32 students in her class, of these students, 14 are girlsl number of outcomes are 252.

It is a branch of mathematics that deals with the occurrence of a random event.

The total number of outcomes can be found by multiplying the number of options for choosing a boy by the number of options for choosing a girl:

Number of outcomes = number of options for choosing a boy x number of options for choosing a girl

Since Mrs. Roslin has 32 students in her class, there are 32 - 14 = 18 boys in her class.

So the number of options for choosing a boy is 18, and the number of options for choosing a girl is 14.

Therefore, the total number of outcomes is:

18 x 14 = 252

Hence, the total number of outcomes is 252.

The vector that describes their hike from their starting position to their final destination is [tex]\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex].

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) A group of hikers walks 3 miles east and then 1 mile north:

[tex]\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex]

(ii) After taking a break, they then hike 4 miles east to their final destination:

[tex]\vec r_{B} = 4\,\hat{i}\,\,\,[mi][/tex]

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

[tex]\vec r = \vec r_{A}+\vec r_{B}[/tex]  (1)

[tex]\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi][/tex]

[tex]\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex]

The vector that describes their hike from their starting position to their final destination is [tex]\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex].
