Please I really do need the answer I’ll mark you as brainlie

Answers

Answer 1

Answer:

44 feet

Step-by-step explanation:

15 + 15 + 7 + 7 = 44

We can take all 4 sides and add them together to find the perimeter (aka how much fencing you need)

hope this helps :)

Answer 2

Answer:

Step-by-step explain to solve for the maximum area, the first derivative should be solved and equate it to zero, then solve for x.

A = 37x - x^2

dA / dx = 37 - 2x

equate dA / dx = 0

0 = 37 - 2x

2x = 37

x = 37 / 2

x = 18.5 ft

so the maximum area is  

A = 37x - x^2

A = 37( 18.5) - 18.5^2

A = 342.25 sq ft

so the answer is letter B

The measure of angle 1 is 125 degrees what is the measure of angle 2?

Answers

Angles 1 is equal to angle 3. Together they add up to 250 degrees. All four angle have to add up to 360. So you do 360 - 250 to get 110 = angle 2 + angle 4. Since 2 and 4 are equal, you have to divide In half to get 55. Angle 2 = 55

find the missing terms in the sequence 24, 33, ?, ?, 60 the question marks are where the missing ones go ​

Answers

It’s 9, add 9 to 33 to get 42, add 9 to 42 to get 51, and add 9 to 51 to get 60. It works

Answer: 42, 51 are the 2 missing terms

Step-by-step explanation: when looking at the sequence, ask yourself if you see a pattern. In this case, to get to 33 from 24, you would add 9 to 24 to get 33. So therefore if you add 9 to 33, you get 42 and if you add 9 to that you get 51 and if you add 9 to that you get 60. And 69 is the last term of this sequence so therefore you know that it worked.

Alex got a iPhone 11 for Christmas as a present. After spending 3 hours on the iPhone Alex decided to walk down the stairs to get a snack in the kitchen, but then he fell down the stairs because he was paying attention to the iPhone. He heard a crack, but luckily it wasn't his iPhone 11. It was his spinal cord.

Compare the price between the iPhone 11 and spinal cord repairence.

(This question was on a question in math and it's kinda funny XD)

Answers

Answer:

The difference between iPhone 11 and Spinal cord repairence is 99,300$.

Step-by-step explanation:

To be honest, this is a really weird question.  But a spinal cord injury can cost up to 100,000$ a year.  And an iPhone 11 cost around 700$.  It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol.  And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.
