Please help I have 15!!!!!!!

Answer:

A

Step-by-step explanation:

In one hour Marty walked three miles..He then stayed there because the line didn't move. If he had walked three more miles, the graph would have been moving up and instead of a horizontal line it would have been a diagonal line .

How you know he came home after 4 hours because right at five hours the line went down to 0 miles from his home. Which means he was at his home.

I hope this helps!

Answer:

688.7

Step-by-step explanation:

Top and Bottom

Area = 3/4 * pi * r^2

r = 6

Area = 3/4 * 3.14 * 6^2

Area =                                                               84.78

Don't round yet.

Vertical surface

Vertical surface = 3/4 * pi * d * h

d = 12 inches (the diameter)

Vertical surface = 3/4 * 3.14 * 12 * 15

Vertical surface =                                          423.9

Two inner faces

They are both rectangles

Area = 2 * L * W

L = 15

w=6

Area = 2 * 15 * 6                                            180

Total                                                               688.68

Total = 688.7

Answer:

5/12!

Step-by-step explanation:

So, imagine the denominator as the whole classroom, i.e. rephrase __ out of 12 to __/12. To get the total class, just add up both groups, which gets you 12! now, 5 out of the 12 kids are girls, so, put 5 in the last sections blank! i hope this helped!!!

By using distance formula (which is attached below), you can solve this problem:

√(x2-x1)^2+(y2-y1)^2

(5, -1) and (5, 3)

√(5-5)^2+(3-(-1))^2

√0^2+4^2

√0+16

√16

4

The distance between the two points is 4.

Answer:yes there is enough space

Step-by-step explanation:

all that you have to do is multiply l x w x h so you can see if there is enough cubic feet.

Answer:

x = 2, -1

Step-by-step explanation:

x² - x + 1 = 3

         - 3  -3

x² - x - 2 = 0

(x -2)(x + 1)

Answer:

x = 2, x = -1

Step-by-step explanation:

Answer:

The correct answer is the third choice, 14 pi.

The choice you selected is wrong.

Circumference =  πD

=  diameter is 14, so its 14π

Answer:

Step-by-step explanation:

13.

 P= 19.42mm

  A= 18.32mm²

Answer:

Half of 6 is 3(new radius)

2 x 3.14 x 3 = 18.84, 18.84 divided by 2 = 9.42

2 + 2 + 2 = 6

6 - 2 = 4

Add lengths:

9.42 + 6 + 4 = 19.42 mm is your perimeter

2 x 2 = 4

3^3 = 9

9 x 3.14 = 28.26, 28.26 divided by 2 (semi circle) = 14.13

Add areas:

4 + 14.13 = 18.13 mm2 is your area

Answer: 3. vertical line test a test used to determine if a graph is a function; states that a vertical line can only go through one point on the graph to be a function.

Answer:

2 x 3 + 7 x 2 + 14 x + 12÷ 2x+ 3 = x² +2x+ 4  

Step-by-step explanation:

We multiply the first term 2x of the divisor with a term ( quotient) to get the first term of the dividend. Then we multiply the same term with each term of the divisor  and subtract it from the dividend. The process continues unless we get the zero or a much smaller number than the dividend as the remainder

               x² +2x+ 4                        

2x+3    ║2 x 3 + 7 x 2 + 14 x + 12

               2x³ + 3x²

                 -      -      

                         4x² +14x+12

                          4x²+ 6x

                        -        -      

                                   8x+12

                                     8x+12      

                                   -        -  

                                     0        

Answer:

Step-by-step explanation:Use the long division method to find the result when 2 x 3 + 7 x 2 + 14 x + 12 2x 3 +7x 2 +14x+12 is divided by 2 x + 3 2x+3

Answer:

38, 26

Step-by-step explanation:

(x+78) + (x-12) +x = 180

3x + 66 =180

3x = 114

x = 38

P = 38-12=26

Answer:

1755 ft³

Step-by-step explanation:

Volume of a rectangular prism = base area x height

Base area = length x width

15 ft x 9 ft = 135 ft²

Volume =  135 ft² x 13 ft = 1755 ft³

Answer:

4

Step-by-step explanation:

Using the nth term formula

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₆ = 2(6) - 5 = 12 - 5 = 7

Then

a₁ + a₆ = - 3 + 7 = 4
