Answers

Answer 1

Answer:

23 yards

Step-by-step explanation:

During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.

Let us represent the height of Devon's rocket = x

18 yards = x - 7 yards

x = 18 yards + 7 yards

x = 23 yards

The height of Devon's rocket = 23 yards

Consider the equation
x
5
− 2 = 11.

Each of these values might be the solution to this equation. Verify the correct solution by substituting each value into the equation. Which is the correct solution?

x = 1.8
x = 2.6
x = 45
x = 65

Answers

Answer:

D) x = 65

Step-by-step explanation:

I just tried B) x = 2.6 and it was wrong.

The true value of x in the equation is 65

How to verify the equation?

The equation is given as:

[tex]\frac{x}5 - 2 = 11[/tex]

When x = 1.8, we have:

[tex]\frac{1.8}5 - 2 = 11[/tex]

[tex]-1.64 = 11[/tex] -- this is false

When x = 2.6, we have:

[tex]\frac{2.6}5 - 2 = 11[/tex]

[tex]-1.48 = 11[/tex] -- this is false

When x = 45, we have:

[tex]\frac{45}5 - 2 = 11[/tex]

[tex]7 = 11[/tex] -- this is false

When x = 65, we have:

[tex]\frac{65}5 - 2 = 11[/tex]

[tex]!1 = 11[/tex] -- this is true

Hence, the true value of x in the equation is 65

The figure below shows a shaded rectangular region inside a large rectangle:

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is a smaller rectangle of length 4 units and width 3 units placed symmetrically inside the larger rectangle. The smaller rectangle is shaded gray.

What is the probability that a point chosen inside the large rectangle is not in the shaded region?

76%
50%
24%
12%

Answers

The area of the smaller rectangle is 12, and the area of the bigger one is 50, so the probability that it is not chosen inside the shaded region is (50-12)/(50)=76%

At the beginning of the year, Alexa had $40 in savings and saved an additional $14 each week thereafter. Joshua started the year with $70 and saved $8 every week. Let AA represent the amount of money Alexa has saved tt weeks after the beginning of the year and let JJ represent the amount of money Joshua has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the amount of money Alexa and Joshua have saved in the week that they have the same amount of money saved.

Answers

Answer:

[tex]A=40+14t[/tex]

[tex]J=70+8t[/tex]

Amount of money Alexa and Joshua have saved in the week that they have the same amount of money saved is equal to $110.

Step-by-step explanation:

Initial amount as savings in account of Alexa = $40

Amount saved per week by Alexa = $14

Initial amount as savings in account of Joshua = $70

Amount saved per week by Joshua = $8

Amount saved by Alexa [tex]t[/tex] weeks after the beginning of the year (A) = [tex]\$(40+14t)[/tex]

[tex]A=40+14t[/tex]

Amount saved by Joshua [tex]t[/tex] weeks after the beginning of the year (J) = [tex]\$(70+8t)[/tex]

[tex]J=70+8t[/tex]

Now solve [tex]40+14t=70+8t[/tex].

[tex]70-40=14t-8t\\30=6t[/tex]

t = 5 years

[tex]A=40+14(5)=40+70=\$110\\J=70+8(5)=70+40=$110[/tex]

Answer:

110 dollars

Step-by-step explanation:

First equation: 14t+40

Second equation: 8t+70

Then find the value of t.

Equation: 14t+40= 8t+70

t=5. Then substitute the value of t into the first equation to get your final answer.

What is the value for x and for y?

Answers

Answer:

20+7x=90

x=10

50+2y=90

y=20

I think
X=10
Y=20
Because a straight line is 180. So 180-20=160 from there you see that one of the angles is a right angle, you can tell this by that it has that little cube in the middle. So 160-90=70 that means that 7x=70 bit you are trying to find for x so divid 70 by 7 that equals 10.
Now to solve for why you have to plug in the information you already know. Vertical angles are congruent. That means that the that the 20 goes straight across and 7x with is actually 70 goes straight across. Now you already know the angle in the middle is 90 but this this it’s split. Since x is 10 multiply 5 by 10 then you get 50 now 90-50=40. 2y is 40 divide it by 2 to get y=20.
I’m bad at explaining so I hope I didn’t confuse you.

The area of the rectangle is 432 square feet. Find the length and width of the rectangle Hello I'm writing a book and I would like your opinion on it! This is just the beginning few pages.Gale! Is Gale here today students? I ran into class, the rain was pouring and I was drenched. Every speckle was so very small, delicate, and clear. I always admired the rain, to me it was a sign but I had not known of what. I sat down on my chair, as the floors got wet and I left a trail of water behind me. I did not realize that I had made the floors wet and that my jacket was cold and saturated. As I take my jacket off and put it in the cubbys that were placed by Arnold Peter, he gives me a gaze, then grabs me by the collar of my jacket that I had already taken half off and slams me to the floor.I looked up to see his face and then I met his eyes, they looked cold and pitiful. Gale! How dare you come to my class late and then pick a fight. You have the nerve. It was Mrs. Walter, she sent me to the principal's office and told me to see her during lunch to mop the wet floor. The principal threatened me with his offer of calling my parents, I didnt know what to say to him, so I just stood there blank. He then called me a disgrace and told me to be ashamed of myself.During lunch I sit alone and the other kids giggle away, I even hear them talk about me. I didnt have anything to eat and my parents didnt pay for my lunch. I guess I didnt mind starving, I was already used to these things and it has always been like this for the past 15 years of my life. I am interrupted from my daydreaming when Mrs. Walter takes me to her class and I start mopping the wet floor. She told me that I needed to fix my attitude and how my grades were suffering. It wasnt even my fault that the other kids liked to tease me. But then again, I was used to it. As the wet floors got dry, I noticed something.The water looked like it was shining, every speckle, glimmered. The lunch bell rings and I rush to my next class, I was hungry and wet from the morning rain so I didnt care much about the fascination the water brought to me. The last bell rings and I run home. The rain poured but I found comfort in it. I looked down at the bakery that was owned by Emma Walterson, my neighbor.She is a 45 year old woman who always cared about me and asked questions. Sometimes she even took me to her house and let me play in her sons consoles. I dont think he liked me that much. I dont look where I am going and get lost in my thoughts. Suddenly, the rain pours harder.Kids were running as their parents pulled up an umbrella. Some had friends that shared their umbrellas with them. Some didnt have one but they enjoyed the company they got from their friends. Then in a flash there was no one there. I guess they had all rushed home and I was just standing there.I started to run, faster and faster but it was like time had frozen. I look around to see the rain, it wasnt falling the trees in the distant were put, not moving. As I turn my head around trying to understand what was happening, the ground starts to shake. I tried pinching myself thinking I was having a bad dream. It wasnt a dream. Three oddly looking shapes appear in front of me. About 6 feet tall, rectangular and lustrous, it wasnt alive and it wasnt moving. It was an object and as I looked closer each of them had a symbol.The first symbol was a droplet of water. The second was a swirl, like the wind. And the third was a hand that held up a flower. I touch each symbol. The first symbol felt like real water as if I was standing there feeling water with my hands.The second symbol, the snowflake felt like it was ice which was no surprise. The third symbol, I couldnt feel. It was just the atmosphere. I then have a urge to fall into a slumber. I stumbled upon and lay down on to the ground. My long sky black hair fell in front of my eyes and my skin became pale. My bright blue eyes closed.That moment I was alone, tried, and starving. No one was there to help me, to carry me, to give me a hand, to lend a shoulder that I could lean on. I was alone, scared, and I didnt know where I was and what was happening to me. I wished for a new start to my so-called life. Finish the lyrics. ROCK editionHeadstrong I'll take you on Plz answer this question correctly can anybody help me with algebra!!!!!!!!!!!!!!!!!
