17. Reasoning: use reverse pemdas, so do addition first. To get rid of the +8, subtract 8 on both sides. This gets you 2x+x+x=68. Then combine like terms to get 4x=68. The to get rid of the 4, divide both sides by 4. This gets you x=17

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

If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.

shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

$h(t) = -16t^2 + 144$

When will the object hit the ground?

It hits the ground after t seconds, and t is found when $h(t) = 0$ . So

$h(t) = -16t^2 + 144$

$0 = -16t^2 + 144$

$16t^2 = 144$

$t^2 = \frac{144}{16}$

$t^2 = 9$

$t = \sqrt{9}$

$t = 3$

3 seconds, so the correct answer is given by option a.

Can someone plz help with math?!

Flura [38]

Answer:

1. <em>L = 3D +59</em>

2. 158 miles

Step-by-step explanation:

For the second part:

Since each day 3 miles of the road is being added, we can simply multiply the number 33 by 3, getting 99. If the road started with 59 miles, we need to add 59 to 99, getting 158 miles.
