If the runner travels 8 miles in 2 hours then the speed of the runner is 4 miles per hour.

The runner traveled 8 miles in 2 hours.

To find the runner's speed, we can use the formula:

Speed (in miles per hour) = Distance / Time

In this case, the distance is 8 miles and the time is 2 hours:

Speed = 8 miles / 2 hours

= 4 miles per hour

So, the runner's speed is 4 miles per hour which means that the runner covers a distance of 4 miles for every hour they run.

Answer:

10/20 or 1/2

Step-by-step explanation:

There are 10 pink balls out of 20. (add all the numbers together)

So that means there is a 10/20 chance to get a pink ball.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

So, the probability is the number of favored outcomes/ number of possible outcomes.

In this case, the favored outcomes is pink, which is 10.

The number of possible outcomes is 2+1+10+2+5 = 20

This gives us 10/20, which is 1/2 when simplified

-3x - y = 7

first, distribute -3:

y + 4 = -3x - 3

then get x and y on the same side and the number on the other side for standard form.

add 3 to both sides:

y + 7 = -3x

subtract y from both sides:

Answer:

  2.5

Step-by-step explanation:

The relative volumes of the two similar boxes will be related by the cube of the dilation factor. That means the dilation factor (d) satisfies ...

  1.2d³ = 18.75

  d³ = 15.625 . . . . . divide by 1.2

  d = 2.5 . . . . . . . . take the cube root

The scale factor the company needs to use is 2.5.

Answer:

  less

Step-by-step explanation:

We can answer the question about relative sizes of a square and a circle by finding the area of each.

__

The area of the square is ...

  A = s²

  A = (2 in)² = 4 in²

The area of the circle is ...

  A = πr²

  A = π(1.2 in)² = 1.44π in² ≈ 4.524 in²

The area of the square is less than the area of the circle.

_____

Additional comment

The area of a circle is π/4 times the area of the square in which it is inscribed. If the diameter of the circle is 1.2 times the side length of the square, its area ratio to the square will be (1.2²)(π/4) = 0.36π ≈ 1.13. That is, the circle is larger and the square is smaller.

By using the first two points on the graph, we conclude that exponential equation is:

y = 200*(0.4)^t

We assume that the equation is an exponential decay of the form:

y = A*(r)^t

When t = 0 we have:

y = A

On the graph we can see that the initial value is 200, then A = 200, so we have:

y = 200*(r)^t

By looking at the graph we can see that:

80 = 200*(r)^1    (this is the second point graphed).

Solving for r we get:

80 = 200*(r)

80/200 = r = 0.4

Then the exponential equation is:

y = 200*(0.4)^t

Answer:

3 1/3 pi inches

Step-by-step explanation:

since we know that when 20 minutes have passed, the minute hand will have moved 4 intervals (i.e. from 12 to 4), and each interval is 30 degrees by measurement. So 4 intervals have a degree measurement of 120 degrees, which is 1/3 of the whole circle (clock). since there isn't any notation on whether pi is taken as 3.14 or 22/7 or whatsoever, you can just say that it has moved (5x2)pi x 1/3 = 3 1/3 pi inches

0.6 can be written in fractions form as;

[tex]0.6 = \frac{6}{10} [/tex]

By simplifying the numeration and denominator by 2, you get;

[tex] \frac{3}{5} [/tex]

Now that we have common denominators we can compare both fractions and say that the one with the higher denominator is larger, Hence=

[tex] \frac{4}{5} > \frac{3}{5} [/tex]

[tex] \frac{4}{5} > 0.6[/tex]

Answer:

4/5 > 0.6

Step-by-step explanation:

Given into Decimal:

4/5 = 0.8

Thus, 0.8 > 0.6

Hence, Answer = 4/5 > 0.6
