Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.
Assume that Lexus skateboards at a constant rate.
Part A
Write an equation to represent the number of miles, m, that Lexus can skateboard in t minutes.

Answers

Answer:

[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]

Step-by-step explanation:

Proportional Model

The number of miles m that Lexus can skateboard in t minutes can be modeled by:

m = kt

It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.

Substituting:

4 = k.20

Dividing by 20

[tex]k=\frac{4}{20}[/tex]

Simplifying:

[tex]k=\frac{1}{5}[/tex]

This produces the model

[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]

I used the equation y=4x+20.

Answer:

  1/30

Step-by-step explanation:

The zeros of the function are ...

-32 (multiplicity 2)5

So, the factorization for some leading coefficient 'a' is ...

  y = a(x +3)(x -2)²(x -5)

and the y-intercept is ...

  y = a(3)(-2)²(-5) = -60a

The graph shows the y-intercept is -2, so we must have ...

  -2 = -60a

  1/30 = a

The leading coefficient is 1/30.

If two fractions are between 0 and 1, can their product be more than 1? please explain. Thank You.

Answers

Answer:

B) always less than either of the original fractions

Step-by-step explanation:

We can easily Answer this by taking some values.

The question states that the two fractions, each have values between 0 and 1.

Let us say one of the fraction is 1/2 and the other fraction is 1/3 .

The product of the two fractions is 1/2 x 1/3 = 1/6 .

is lesser than both 1/2  and 1/3 .

So, the correct answer is that the product is always less than either of the original fractions.

The two fractions are between 0 and 1 their product will always less than either of the original fractions.

What is fraction?

A fraction is number expressed "as quotient, in which the numerator is divided by denominator".

According to the question,

If two fractions are between 0 and 1. In order to check their product be more than 1.

Let us assume one fraction is 1/2 and the other fraction is 1/3. The product of the two fractions:

1/2 x 1/3 = 1/6.

Since the value of fraction 1/2 is 0.5, the value of fraction 1/3 is 0.3333 and the value of fraction 1/6 is 0.166667.

It clearly shows 0.5 > 0.16667 and 0.3333 > 0.16667.

Hence, the two fractions are between 0 and 1 their product will always less than either of the original fractions.

three cones have a volume of 192π cm³.Cone A has a radius of 2 cm. Cone B has a radius of 3 cm. Cone C has a radius of 4 cm. find the height of each one

Answers

9514 1404 393

Answer:

  A: 144 cm

  B: 64 cm

  C: 36 cm

Step-by-step explanation:

The volume of a cone is given by ...

  V = (1/3)πr²h

Solving for h, we get ...

  3V/(πr²) = h

Filling in the given values, we get ...

  3(192π)/(πr²) = h

  576/r² = h

Then the heights of the different cones are ...

  A: r = 2, h = 576/4 = 144 . . . cm

  B: r = 3, h = 576/9 = 64 . . . cm

  C: r = 4, h = 576/16 = 36 . . . cm

Answer:

c = 15

Step-by-step explanation:

The angles are4 a linear pair and are supplementary, so the sum of their measures is 180 deg.

7c - 7 + 6c - 8 = 180

13c - 15 = 180

13c = 195

c = 15

The answer should be 15.

Explanation:
The line equates to 180, so you would put both equations (7c-7 , 6c-8) together and equal it to 180°.
So, it would come out looking like this:
7c-7+6c-8=180.

You’d add 7c and 6c to get 13c, and then subtract -8 from -7 (-7-8) to get -15.
The equation would now look like this.
13c-15= 180.

You’d add 15 to 180 to get 195. Then, you’d divide 195 by 13 to get 15, which would mean c=15.
