Answer:

$\frac{20}{7}$ hours per day

Step-by-step explanation:

Given,

Distance = 192 miles

Rate = 9.6 miles per hour

Lets find her total time of riding by using Distance Formula ( D = RT ).

D = RT

192 = 9.6T

T = 192/9.6

T = 20 hours

Total time she needs to meet goals is 20 hours.

There are 7 days in a week and she plans to ride same hours each day, so that will be:

20/7 hours per day

you are playing a game. you start at 0. then you score -8 points on each of 4 turns. what is your score after those 4 turns

Sidana [21]

Since you multiple the -8 points you earned on each of the 4 turns times the number of terms, -8 times 4 is -32. Your score would be -32

The University of Central Florida's cheerleading team has eighteen males and twenty-one females. If h represents the height of a

Anuta_ua [19.1K]

Answer:

The range of heights of the cheerleaders is the interval [58, 74)

All real numbers greater than or equal to 58 inches and less than 74 inches

Step-by-step explanation:

we have

$260 \leq 4h+28$

Divide the compound inequality into two inequalities

$260 \leq 4h+28$ -----> inequality A

$4h+28$ -----> inequality B

Solve inequality A

$260 \leq 4h+28$

Subtract 28 both sides

$232 \leq 4h$

Divide by 4 both sides

$58 \leq h$

Rewrite

$h \geq 58\ in$

Solve the inequality B

$4h+28$

Subtract 28 both sides

$4h$

Divide by 4 both sides

$h$

therefore

The range of heights of the cheerleaders is the interval [58, 74)

All real numbers greater than or equal to 58 inches and less than 74 inches

What are the coordinates of the center of the ellipse shown below?

photoshop1234 [79]

Answer:

Option D (7, -3)

Step-by-step explanation:

We know that the general equation of an ellipse has the form:

$\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} = 1$

Where the point (h, k) are the coordinates of the center of the ellipse

In this case the equation of the ellipse is:

$\frac{(x-7)^2}{4} + \frac{(y+3)^2}{16} = 1$

Then

$h=7\\\\k = -3$

So The coordinates of the center of the ellipse are (7, -3)

If ADEF is reflected over the x-axis, what would be the coordinates of point F?

Brut [27]

Answer:

Please check the explanation.

Step-by-step explanation:

Let the coordinates of the point F be (x, y).

When a point F(x, y) is reflected over the x-axis, the x-coordinate of the point F remains the same, and the y-coordinate of the point reverses the sign.

Thus, the rule of reflection over the x-axis:

F(x, y) → F'(x, -y)

Here,

F'(x, -y) would be coordinates of point F after the reflection over the x-axis.

Let say, the point F(1, 2).

The coordinate of the point F after the reflection over the x-axis would be:

F(1, 2) → F'(1, -2)

Thus, F'(1, -2) would be the coordinates of point F after the reflection over the x-axis.
