Audrey was driving down a road and after 4 hours she had traveled 86 miles. At this speed, how many miles could Audrey travel in 6 hours?

Answer:

x = 28

m<ABC = 57°

Step-by-step explanation:

✔️(2x + 1)° + 33° = 90° (complementary angles)

Solve for x

2x + 1 + 33 = 90

Add like terms

2x + 34 = 90

2x = 90 - 34 (subtraction property of equality)

2x = 56

Divide both sides by 2

x = 28

✔️m<ABC = 2x + 1

Plug in the value of x

m<ABC = 2(28) + 1

= 56 + 1

m<ABC = 57°

Answer:

x = 28 & m<ABC = 57°

f(x) = 2x

f(-4) = 2(-4) = -8

Answer:

1. n + 8 = 10

2. [tex]\frac{n}{12}[/tex]= 10

3. 8n - 6 = 34

4. 3(n + 12) = 45

5. No

6. Yes

Step-by-step explanation:

(only for questions 5 and 6)

5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.

6. If you substitute in b = 8, you get:

[tex]5(8-3)= 25\\5(5) = 25\\25 = 25[/tex]

this is true.

Answer:

(x-¾)² = 49/16

Step-by-step explanation:

0 = 2x² - 3x - 5

2x² - 3x = 5

Divide by the leading coefficient

x²-(3/2)x = 5/2

Complete the square

 coefficient of the x term: 3/2

 divide coefficient in half: ¾

 square it: (¾)²

 add (¾)² to both sides to complete the square and keep the equation balanced:

x²-(3/2)x + (¾)² = 5/2 + (¾)²

(x-¾)² = 49/16

If you need to solve for x:

x-¾ = ±√(49/16) = ±7/4

x = 5/2, -1

Answer:

240

Step-by-step explanation:

You have to find the area of each indivigual side and then add all the areas together. So like 9x5 is 45 so you take 45 and multiply it by 4 since there are 4 sides identical to that side and then you get 180. Then you multiply 6x5 and that gives you 30 which you then multiply by 60, so then all you gotta do is 60+180=240.

so find the circumference of the circle using c=2*pi*r it's like 18.849. then find the perimeter of the box so p=2l+2w and it's like 38. so subtract the circle circumference from 38 so 38-18.849=19.15

The area of the shaded region is the difference between the area of the rectangle and the area of the two congruent semi-circles. Then the area of the shaded region is 49.73 square units.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The dimension of the rectangle is 13 by 6 units.

The radius of the semi-circle is 3 units.

The area of the shaded region is the difference between the area of the rectangle and the area of the two congruent semi-circles.

[tex]\rm Shaded \ area = Area \ of \ rectangle - Area \ of \ 2 \ semi-circles \\\\Shaded \ area = 13 * 6 - 2*\dfrac{\pi * 3^2}{2}\\\\Shaded \ area = 78 - 9 \pi \\\\Shaded \ area = 78-28.274\\\\Shaded \ area = 49.73[/tex]

Answer:

Option D: -3 is the correct answer.

Step-by-step explanation:

Given points are:

(-1, 6) and (2,-3)

We have to find the slope.

Slope is the steepness of a line. It is denoted by m.

Slope = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Here,

x1 = -1 , y1 = 6

x2 = 2, y2 = -3

Putting the values in the formula of the slope.

[tex]m=\frac{-3-6}{2-(-1)}\\\\m=\frac{-9}{2+1}\\\\m=\frac{-9}{3}\\\\m=-3[/tex]

Hence,

Option D: -3 is the correct answer.

Answer:

  (b)  No, both are wrong

Step-by-step explanation:

Compare the given equation to the form ...

  y = mx + b

You see that m = 1/3, and b = -1.

b is the y-intercept, the point where the graph crosses the y-axis. In the equation, that value is -1. In the graph shown, that value is +1, so we know the y-intercept is wrong.

__

m is the slope. This is the ratio of "rise" to "run". A slope of 1/3 means the graph goes up 1 unit for each 3 units to the right. The slope of the line on the graph shown is about 3: it rises 3 units for each 1 unit to the right. So, we know the slope is wrong.

__

That is, both the slope and y-intercept of the graphed line are different from those of the given equation. Corey is not correct. The attachment shows a correct graph.

Step-by-step explanation:

To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.

We try out all the options:

39² = 1521, 15² + 36² = 1521.

12² = 144, 8² + 4² = 80.

17² = 289, 13² + 9² = 250.

Since 39² equals 15² + 36², option A is the correct answer.

Answer:

the number of miles is 160

Step-by-step explanation:

The computation is given below:

Let us assume the miles be x

For company A

y = $100 + $0.40x

And, for company B

y = $20 + $0.90x

In order to find out the number of miles, the rental cost of the company A should be less than the company B rental cost

SO,

$20 + $0.90x > $100 + $0.40x

Subtract $20 from both sides

0.90x > 80 + 0.40x

Now subtract 0.40x from both sides

0.50x >80

x>160

So the number of miles is 160

Step by step explanation:

Answer:

a.) each line segment represents a length of 1/8

b.) N = 3/8

c.) -3/8

Step-by-step explanation:

a.) In order to find the interval / length of each line segment, simply count how many line segments there are until you reach one whole integer. Basically, start on one number and count how many sections until the next number.

So for this example, let's start counting from the number 0. From 0 to the next number, 1, there are a total of 8 sections from 0 to 1, so they're each split up into 1/8s.

b.) Count each line as 1/8 from 0 to N to get what N represents. So from 0 to N, there are 3 lines/portions, so N is 3/8 because 1/8 + 1/8 + 1/8 = 3/8

c.) Just put a negative sign in front of N to get the opposite
