Answer:

25 mph

Step-by-step explanation:

Answer:

The value of a is 15.

Step-by-step explanation:

First, you have to find the total interior angles of the polygon using the formula, sum = (n-2)×180°, where n represents the number of sides :

sum = (n-2)×180°

sum = (5-2)×180°

sum = 540°

Given that the sum of the interior angle is 540° so in order to find the value of a, you have to add up all the angles in terms of a :

3a + 150 + 8a + 6a + 9a = 540

26a + 150 = 540

26a = 390

a = 390 ÷ 26

a = 15

Here you go! Work shown too.

Answer:

About 95% of households have an income over $54,550

Step-by-step explanation:

95% is a probability of around 0.95

So we start by calculating the z-score with a probability of 0.95

We can use the standard normal distribution table for this

the z-score is -1.645

Mathematically;

z-score = (x-mean)/SD

-1.645 = (x-71,000)/10,000

10,000 * -1.645 = x-71,000

-16450 = x - 71000

x = 71,000 - 16450

x = 54,550

Answer:

(-3,0) = x and (0,4) = y

1: 60 - 25% = 45 minutes

2: 60 - 75% = 15 minutes

Answer:

15 minutes because 25 percent goes in 4 times to 100 so 60 divided by 4 is 15

45 minutes because 75 percent goes in 3 times to 100 and 15x3 is 45

Answer:

4/225

Step-by-step explanation:

To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)

So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.

The probability of getting a red is:

10/15 = 2/3

The probability of getting a blue is:

3/15 = 1/5

The probability of getting a yellow is:

2/15

So to get all 3 different colors:

2/3 * 1/5 * 2/15 = 4/225

Answer:

15x -45y +180

Step-by-step explanation:

5(3x)= 15x

5(26)= 130

5(-9y)= -45y

5(10)= 50

combine like terms:

15x - 45y +180

Answer: 1 1/5

Step-by-step explanation:

Answer:

Mixed number- 1 and 1/5

Fraction- 12/10

Step-by-step explanation:

1.2 is read as 1 and 2 tenths. 1 and 2 tenths is the same as 1 and 2/10.

1 and 2/10 in simplest from is 1 and 1/5.

1 and 1/5 can also be written as 12/10.

Answer:

He walks 1030 meters if he walks across the park.

Step-by-step explanation:

In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....

Let "c" be the distance he will need to walk if he was going to go through the park

Let "a" be the distance he walks on King Street

Let "b " be the distance he walks on Queen Street, then.....

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c = \sqrt{a^{2} + b^{2} }[/tex]

(Now plug in the values of a and b and get.....)

c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]

c = [tex]\sqrt{1060000 }[/tex]

c = 1029.563014............

So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

Answer:

x = 12

Step-by-step explanation:

Let a = the length of the missing side

[tex]\frac{24}{30} = \frac{44}{a}[/tex]

simplify: [tex]\frac{4}{5} = \frac{44}{a}[/tex]

use cross multiplication

4a = 220

a = 55

7x + 15 = 44 + 55

7x = 84

x = 12

Answer:

3x = -2 2/5 or -2.4

Step-by-step explanation:

5x + 8 = 4

5x = 4 - 8

5x = -4

x = -4/5

3x = y  If x = -4/5

3 * -4/5 = y

-12/5 = y

-2 2/5 = y

Answer:

-√7/4

Step-by-step explanation:

Mathematically;

Sine is the ratio of opposite to hypotenuse

So here, hypotenuse is 4

The opposite is 3

To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides

Let the adjacent be x

4^2 = 3^2 + x^2

x^2 = 16-9

x^2 = 7

x = √7

The cosine is the ratio of the adjacent to the hypotenuse

Since we want to consider quadrant II

Cosine is negative here;

So the answer for Cos will be;

Cos theta = -√7/4

Answer:

Solve equation [2] for the variable y

[2] y = 8x + 7

// Plug this in for variable y in equation [1]

[1] 4x - 5•(8x+7) = -9

[1] -36x = 26

// Solve equation [1] for the variable x

[1] 36x = - 26

[1] x = - 13/18

// By now we know this much :

x = -13/18

y = 8x+7

// Use the x value to solve for y

y = 8(-13/18)+7 = 11/9

Solution :

{x,y} = {-13/18,11/9}

y=2x+1

(2x) is the slope because the slope is going up the slope will be positive and the (1) is the y intercept which means where the slope crosses the vertical line

Answer:

A

Step-by-step explanation:

The equation for a graph is y=mx+b

The b is the y-intercept, or what the y-value is at x=0 (x is horizontal or left and right, y is vertical or up and down). At x=0, y is at 1, so it has to be +1.

The m is the slope, or the rise over run, which you solve by doing the equation (y2-y1)/(x2-x1).   You do this by taking one set of coordinate positions, let's say (0,1), and another, let's say (1,3).    The first set is your x1 and y1, and the second set is your x2 and y2. In this case, x1=0,y1=1,x2=1,y2=3

then do the equation. (3-1)/(1-0)   2/1=2, so the slope, or m, is 2.

Answer:

200+40+3+0.7+0.09

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

5x + 2 and 4x + 6 are alternate angles and are congruent, thus

5x + 2 = 4x + 6 ( subtract 4x from both sides )

x + 2 = 6 ( subtract 2 from both sides )

x = 4
