Answer:

This is kind of late, but I hope I could help maybe for a later assignment or assesment.

The estimates of y have become increasingly more precise, with some of the earlier ones having a margin of error of more than 0.8

None of the estimates support newton's theory that y=0

Most of the estimate support Einstein, or at least have a margin of error that accounts for einstien.

A bicycle tire has a diameter of 62 cm

anzhelika [568]

Answer

1946.8 cm

Step-by-step explanation:

you first need to find the circumference of the tire. to do this you use the formula C=d(3.14)

you plug in the 62 to the d

62 times 3.14 = 194.68

and multiply that by 10 because it is 10 revolutions to get 1946.8 cm

Hello, how was your day, help? ^ ^<br> solve for x

Natali5045456 [20]

Hi there!

I believe your answer is:

$\boxed{x=100}$

»»————-　★　————-««

Here’s why:

Recall the Triangle Angle Sum Theorem: The three angles of all triangles add up to a sum of 180°.
We will set up an equation based on this and then solve.

⸻⸻⸻⸻

$\boxed{\text{Solve for 'x':}}\\\\58 + 22 + x = 180\\-----------\\\rightarrow 80 + x = 180\\\\\rightarrow 80 - 80 + x = 180 - 80\\\\\rightarrow \boxed{x=100}$

Hope this helps you. I apologize if it’s incorrect.

We created this inequality to represent how Amy can meet her revenue goals:

brilliants [131]

Answer:

x = 2

Price = $29

Step-by-step explanation:

If x is the number of $2 dollars increases, then the minimum number of increases required to meet her goal is:

$-100x^2 + 15,750x + 212,500 \geq 243,600\\-100x^2 + 15,750x -31,100\geq 0\\x^2 -157.5x + 311\geq 0\\x=\frac{157.5\pm\sqrt{157.5^2-(4*1*311)} }{2}\\ x_1= 2\\x_2=155.5$
