Charlotte has $37. She wants to buy a ski pass for $125. She can earn $8 per hour at her summer job.
- Enter an inequality that represents the number of hours (h) Charlotte could work to earn at least enough money to buy the ski pass.

Answers

11 hours because the ticket is $125 - $37 she already got = she just needs $88 dollars divided by $8 per hour equals 11 hours she need to get enough for the ticket

Answer:

8h + 37 = 125

Step-by-step explanation:

if she already has 37, you can take 37 from 125. you should have 88 left.

if you do the math, 8 x 11 is 88. so she needs to work 11 hours to be able to pay for the ski pass.

a guidebook says this tower is 50m tall.Is that correct? given deegrees are 27° and 46°
​

Answers

9514 1404 393

Answer:

   yes

Step-by-step explanation:

The tower is about 50.1 meters tall. The guidebook is correct.

__

The distance from the base of the tower to the angle vertex is ...

  d1 = h/tan(46°)

  d2 = d1 +50 = h/tan(27°)

Then the height of the tower is ...

  h/tan(46°) +50 = h/tan(27°)

  50 = h(cot(27°) - cot(46°))

  h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692

  h ≈ 50.1544 . . . meters

The tower is more than 50 meters high.

Red copper costs $0.90 for 7.6m and yellow copper costs $1.12 5.2m. Estimate how much each amount of copper costs.

Answers

Answer: Red copper = $0.12 per meter

Yellow copper = $0.22 per meter

Step-by-step explanation:

Since Red copper costs $0.90 for 7.6m, the cost of 1m of red copper will be:

= $0.90/7.6

= $0.12

Since yellow copper costs $1.12 5.2m, the cost of 1m of yellow copper will be:

= $1.12 / 5.2

= $0.22 per meter

A triangle has side lengths of
(x-8) (4x2 – 3) and (4x2 + 4).
If the perimeter is 650 units, what is the value of x?​

Answers

Given:

The three sides of a triangle are:

[tex](x-8),(4x^2-3),(4x^2+4)[/tex]

The perimeter of the triangle 650 units.

To find:

The value of x.

Solution:

Perimeter of a triangle is the sum of all three sides of the triangle. So,

[tex]Perimeter=(x-8)+(4x^2-3)+(4x^2+4)[/tex]

[tex]Perimeter=8x^2+x-7[/tex]

The perimeter of the triangle 650 units.

[tex]8x^2+x-7=650[/tex]

[tex]8x^2+x-7-650=0[/tex]

[tex]8x^2+x-657=0[/tex]

Splitting the middle term, we get

[tex]8x^2+73x-72x-657=0[/tex]

[tex]x(8x+73)-9(8x+73)=0[/tex]

[tex](x-9)(8x+73)=0[/tex]

Using zero product property, we get

[tex](x-9)=0\text{ and }(8x+73)=0[/tex]

[tex]x=9\text{ and }x=-\dfrac{73}{8}[/tex]

For negative value of x, the side [tex](x-8)[/tex] will be negative, which is not possible because the side of a triangle cannot be negative.

Therefore, the only value of x is 9.

The cost to mail a package varies directly to the weight of the package. If a 14- ounce package costs $4.48 to mail, find the weight of a package that cost $8 to mail. ​

Answers

Answer:

Step-by-step explanation:

Ok so first, we must figure out what 1 once costs. This can be done by divideing 4.48(cost) by 14(weight).

You should get 0.32.

Now just multiply by 8 and you should get your answer. This answer is 2.56.

Answer:

2.56

Another way this can be done is dividing 8(second weight) by 14(first weight) which will get you the difference. This is 0.5714 blah blah blah goes on for a long time. Now, take this number and multiply it by the 4.48(first cost). This should get you 2.56.

I'll give brainliest. (this if or the people who feel like giving up) Dear Person,First I am going to say, dont give up. You have worked so hard to get to where you are. Yes, the easy thing would be to just go home and give up on whatever is giving you troubles but, what comes easy wont last and what lasts wont come easy. Dont lose sight of your dreams, youre probably a lot closer than you think. If you're not following your dreams then you aren't truly living and you don't truly love what you are doing. You have to love what you do. If you haven't found it yet, there is still time, keep looking. You have to figure out what it is that you want and chase it. Soon, your life will become a series of trying to get someplace else. Dont settle.Most people give up on themselves easily. They give up because they feel as though they have tried too many times and it just never works out. But you never know, the next time you try could be the time everything falls into place. Your time here is limited so don't waste it by living someone else's life. Live your own life. Everyone has opinions on who you should be or what you should do; don't let the noise of other's opinions drown out your inner voice. Have the courage to follow your heart and intuition.It takes courage to act. It takes courage to start over again. Have the courage to be who you want to be. No fear. Fear kills dreams...fear kills hope...fear can age you...fear can hold you back. Dont be afraid; make your goals become a reality. Accept where you are and the responsibility that you're going to take yourself where you want to go. It's not going to be easy- if it were easy everyone would do it. But know that you can do it. Everyday you say no to your dreams, you're pushing it back a lot farther than just a day.I may not know what your situations are like. I may not be in any position to tell you what to do or how to live your life. But I do know that everyone gets a second chance. Even if it is tearing you to pieces, just stop and think about it. The world may seem like it is ending and there is absolutely nothing you can do...this is when you need to be strong. You never know how strong you are until strong is the only choice you have. Show your strength. Everyday we grow old and everyday we have one less day in our futures and one more day in our past God Bless loves keep yalls heads up... DOnt let yalls crowns slip Work out m and c for the line:y=11x
