Cameron is flying 8,000 feet above sea level. Directly below her, she sees a whale 50 feet below sea level. Which absolute value expression represents the distance between Cameron and the whale? A) |8,000 − 50| B) |8,000 − (−50)| C) |−8,000 +50| D) |−8,000 − (−50)|

Answers

Answer:

D) |−8,000 − (−50)|

Step-by-step explanation:

When we are dealing with questions involving above or below sea level,

The formula for the Absolute value expression representing the distance = | Height above sea level -(Distance below sea level|

Height of Cameron above sea level = 8000ft = -8000

Distance of the whale below sea level = 50ft = -50

Hence, we have:

|−8,000 − (−50)|.

               = (c -10) (c -4)

e²  + 10e +16

Sum = 10

Product = 16

Factors= 2 , 8

e² + 10e + 16 = e² + 2e + 8e + 2*8

                      = e(e + 2) + 8(e + 2)

Product = -24

Factors = 3 , -8

h²  - 5h - 24 = h²  + 3h - 8h - 3*8

Product = -12 * 3 = - 36

Factors = -9 , 4

What are the solutions to the equation 0 = x2 – x –6? Select two options

x = –3
x = –2
x = 0
x = 2
x = 3

Answers

Answer:

-2 or 3

Step-by-step explanation:

Step 1: Factor equation.

(x+2)(x−3)=0

Step 2: Set factors equal to 0.

x+2=0 or x−3=0

x=−2 or x=3

-2 and 3 are the solutions to the equation x² – x – 6 = 0

To determine the solutions of the equation x² – x – 6 = 0

x² - x - 6 = 0

x² - 3x + 2x - 6 = 0

x (x - 3) + 2(x + 3) = 0

(x + 2) (x + 3) = 0

(x + 2) = 0

x = - 2......(1)

(x + 3) = 0

x = - 3..........(2)

x = −2 or x = 3

Therefore, -2 and 3 are the solutions to the equation  x² – x – 6 = 0.

Jason had three more than four times the amount of money that Jeff has. Together they have $72. How much money does each person have?

Answers

Answer:

Jason has $58.20 and Jeff has $13.80.

Step-by-step explanation:

Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.

We know that together they have $72. So, we can write the following equation:

[tex]x+y=72[/tex]

We know that Jason has three more than four times the amount of money Jeff has. So:

[tex]x=3+4y[/tex]

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

[tex](3+4y)+y=72[/tex]

Combine like terms:

[tex]5y+3=72[/tex]

Subtract 3 from both sides:

[tex]5y=69[/tex]

Divide both sides by 5:

[tex]y=69/5=\$13.80[/tex]

So, Jeff has $13.80

We know that Jason has three more than four times the amount of money Jeff has.

Therefore, Jason has:

[tex]x=13.8(4)+3[/tex]

Multiply and add:

[tex]x=\$58.20[/tex]

So, Jason has $58.20 and Jeff has $13.80.

And we're done!

Find the measures of the complementary angles that satisfy each case.

The measure of the first angle is 40° less than the measure of the second.

Answers

Answer:

25° and 65°

Step-by-step explanation:

1. 65°-25°= 40°

2. 90°-65°=25°

3. 90°-25°=65°

Therefore 25° and 65° fit the criteria, make sure to add the degrees symbol :)

Complementary angles have a sum of 90° thus measure of the first and the second angle is 25° and 65° respectively.

What is an angle?

Angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Let's suppose the first angle is x while the second is y.

If two angles have a sum of 90° then they will be called as complementary angles since x and y are complementary.

x + y = 90

Now given that,

The measure of the first angle is 40° less than the measure of the second.

x = y - 40

x - y = -40

By adding both equations,

(x + y) + (x - y) = 90 + (-40)

2x = 50

x = 25

y = 90 - 25 = 65

Hence "The first and the second angle is 25° and 65° respectively".

Title: ("Sunday at the Water Park") "Yeah, the job is pretty boring," Mariah admitted, looking at the wave pool from atop her lifeguard station. " But I get to be outdoors, and I can go on all the rides for free when I'm done." Her questioner - Berry, a classmate she didn't know well, who happened to be a customer as well as being the annoying editor of the school newspaper - stretched his arm up toward her in some weird kind of salute. Actually he was recording her with the purple-and-black striped phone in his hand. " How are the working conditions?" he inquired in the important tones of an anchorman. "They're -" She stopped cold. She stood up, staring at the crowd who rose and fell and squealed with each new surge of machine-churned water. Amid the bobbing figures, she had seen one stop moving, and seen its head sink halfway under the water and stay there. She grabbed the rescue tube and dove into the pool. In what felt like an instant, she had swum to the far end, a few feet from the wave machine, and stopped behind the eight-year old boy who was floating face -down. She thrust the long, red foam rescue tube at him. Then, she stood in the three-foot deep water and scooped him around the waist. As she lifted his head, a waterfall of clear, bubbly water streamed down. She wrapped both his small, soft hands around the flotation tube and towed him to the side of the pool. She hoisted him high and set him on the brightly painted white cement, then boosted herself up after him. The boy-his name turned out to be Peter-hadn't fully lost consciousness, so he didn't need CPR. After a couple of slaps on the back, he was coughing wetly and breathing well, though too stunned even to ask what had happened. By now, the waders in the pool understood vaguely what had happened. They looked around helplessly and asked each other bewildered questions. No one had noticed that Peter was drowning, not even the adults three feet away from him. Peter's teenage brother and his friends had sloshed as quickly as they could to poolside. In five minutes, the EMS ambulance arrived to take Peter to the nearby clinic. " I got it all on video!" Berry exclaimed. " Now give me an interview!" She couldn't give him much of an interview, because the event had lasted only thirty seconds. She hadn't consciously decided how to act and didn't remember many details. Her reflexes had done it all automatically. Her lifesaving courses had worked! She hardly knew what she was saying during the interview and assumed she must sound incredibly dumb and out of breath. Later her family and neighbors told her how poised and in-charge she'd appeared. The strange thing was, she didn't feel as if she'd done anything special.
