Carmen ran one mile in 7 minutes. At this rate, how long will it take her to run 5 miles?

Answer:

Option 3

Step-by-step explanation:

Because only the constant is changed.

Work Shown:

x = 2 is the input

y = 2x+1

y = 2(2)+1

y = 4+1

y = 5 is the output

 A function is a relationship between inputs where each input is related to exactly one output.

The value of the output of function 2x + 1 when x =2 is 5.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

1.

f(x) = 3x + 2

x = 1,

f(1) = 3x1 + 2 = 3 + 2 = 5

Input = 1

Output = 5

2.

g(x) = 4x + 2

For x = 1, g(1) = 4x1 + 2 = 4 + 2 = 6

Input = 1

Output = 6

We have,

Function:

2x + 1

Input = 2

The value of the output of the function 2x + 1 when x =2:

= 2x + 1

= 2x2 + 1

= 4 + 1

= 5

Thus,

The value of the output of function 2x + 1 when x =2 is 5.

Answer:

Diameter of the ball = 8 inches

Radius of the ball (r) = diameter ÷ 2 = 8 ÷ 2 = 4 inches

π = 3.14

Surface area of the ball (A) is the same as the surface area for a sphere = 4 π r² = 4 × 3.14 × 4² = 200.96 inches²

Step-by-step explanation:

hi nice to meet you

Using the formula of volume of sphere, the volume of the rubber ball is 14[tex]inches^{3}[/tex] approximately.

The volume of sphere is the amount of space occupied, within the sphere.

Diameter of sphere = 3 inches

Radius of sphere = 3/2 = 1.5 inches

Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex] = [tex]\frac{4}{3}*\frac{22}{7}*1.5^{3}[/tex] = 14.13 [tex]inches^{3}[/tex]

Sorry if i'm wrong

Answer:

I think it's 1800 Degress

Step-by-step explanation:

If the CD rotates 300 times per minute, we know that equals 300 rotations/60 seconds

That ends up being 5 rotations per second.

Since we know that a full rotation is 360 degrees, then it should equal 1800 degrees.

Hey there!

Slope: 7-3/1-(-1), which is equal to 4/2, or 2.

Point slope: y-7=2(x-1)

So choice B is correct.

Answer:

C(p) = 0.25p + 5

Step-by-step explanation:

$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.

m = slope, b = y-intercept

C(p) = mp + b

C(p) = 0.25p + 5

Answer:

50

Step-by-step explanation:

The way you solve this is by creating an inequality of

30          15

----     =   ----

100          x

So you cross multiply which would give you 30x = 1500, then you divide by 30 on both sides leaving you with 50. If you want to check it, you can then multiply 50 by .30 which would give you 15.

Answer:

D) 8

Step-by-step explanation:

8 x 2.5 = 20

and the rest is adult haircuts

6 x 5 = 30

Answer:

D) 8 Children’s Haircuts

Step-by-step explanation:

Let a represent the amount of adult haircuts and c represent the amount of child haircuts.

We know that she gave exactly 14 haircuts. So:

[tex]a+c=14[/tex]

We also know that she made $50.00. Therefore, the price of each haircut times their respective amounts will total $50. So:

[tex]5a+2.5c=50[/tex]

This is now a system of equations.

We can solve this using substitution. From the first equation, let’s subtract c from both sides:

[tex]a=14-c[/tex]

Now, we can substitute this into the second equation for a. This yields:

[tex]5(14-c)+2.5c=50[/tex]

Distribute:

[tex]70-5c+2.5c=50[/tex]

Combine Like Terms:

[tex]70-2.5c=50[/tex]

Subtract 70 from both sides:

[tex]-2.5c=-20[/tex]

Divide both sides by -2.5:

[tex]c=8[/tex]

Therefore, Kate gave 8 children’s haircuts.

This means that she gave [tex]14-8=6[/tex] adult haircuts.

So, our answer is D. She gave 8 children’s haircuts.

Answer:

Gradient = Change in y / Change in x

Gradient = (-7-3) / (0-4)

Gradient = -10/-4

Gradient = 2.5

So the answer is 10/4, which is 2.5

The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.

Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 3 - (-7) / ( -4 - 0 )

Slope = 10 / -4

Slope = -5 / 2

Step-by-step explanation:

Answer:

[tex]y=\frac{5}{3}x+8[/tex]

Step-by-step explanation:

Remember, slope intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

To get the given equation into slope-intercept form, we would have to first solve for y in terms of x.

10x - 6y = -48

Subtract 10x from both sides.

-6y = -48 - 10x

Multiply both sides by -1.

6y = 10x + 48

Divide both sides by 6.

[tex]y=\frac{5}{3}x+8[/tex]

And now, looking at the equation that we found and the equation for slope-intercept form, we can see that we have found the equation for 10x - 6y = -48 in slope-intercept form.

  y = 2/3x -23/3

Step-by-step explanation:

In a version of point-slope form this is ...

  y = m(x -h) +k . . . . . line with slope m through point (h, k)

Expanding this, we have ...

  y = mx +(k -mh) . . . . slope-intercept form

For the given point and slope, the equation is ...

  y = 2/3x +9 -2/3(2)

  y = 2/3x -23/3
