Can someone please help me! i’m confused!

Answer:

[tex]x^2 + (y-60)^2 = 30,625[/tex]

Step-by-step explanation:

There are 42 carts, so there is 42 spaces in between them; if one of those spaces are 25pi/3 feet long, then 42 of them would be 25*42*pi/3 = 350pi (Perfect! no fractions)

350pi is the circumference. Now if we plug that into the circumference equation we get:

C = 2pi*r

350pi = 2pi*r

Divide both sides by pi to get rid of it

350 = 2r

Divide both sides by 2

r = 175 feet

So the new equation to graph it is:

x^2+y^2 = 175^2 = 30,625

We also know that the center of the Ferris wheel has to be at least 60 feet from the ground. Since the radius is more than that, a good bit of the Ferris wheel has to be underground OR we can make it higher (keyword: at least) if we want it to be above ground. I'll do the equation for underground since it more closely represents the question.

subtracting a number from y, shifts the graph up that much so:

[tex]x^2 + (y-60)^2 = 30,625[/tex]

I can't really draw it electronically but I can graph it:

Answer:

D

Step-by-step explanation:

Let the number be n.  Then "a number divided by 22" would be n/22 (Answer D)

The number divided by 22 can be written as x / 22, so option D is correct.

It is a fundamental operation in mathematics where you divide a number into smaller parts.

Given:

A number divided by 22,

Here, the divisor = 22

Assume the number is x

Then, dividend = x

Thus, expression can be written as,

dividend/divisor = x / 22

Answer:

160 ft, 250ft

Step-by-step explanation:

Rectangular base:

Width = w

length =2w - 70

Perimeter = 820 ft

2*(length + width) = 820

2*(2w - 70 + w ) = 820

2 *(2w + w - 70) = 820     {Combine like terms}

2* (3w - 70) = 820

3w*2 - 70*2 = 820

6w - 140  = 820    

6w  = 820 + 140     {Add 140 to both side}

6w = 960     {Divide both sides by 6}

w = 960/6

w = 160 ft

length = 2*160 - 70

          = 320 - 70

          = 250 ft

Answer:

The answer is C

Step-by-step explanation:

48/112 = 0.4285

convert and round it

0.4285 = %42.9

The percent of the 7th grade students were in favor of wearing school uniforms is 42.9%.

From the given table,

7th grade students who are in favor of wearing uniform = 48

Total 7th graders = 112

So, the percent of the 7th grade students were in favor of wearing school uniforms

= 48 / 112 x 100

= 12 / 23 x 100

= 42.85%

HOW TO CONVERT 1/25 TO A PERCENTAGE?

To write 1/25 to a percentage, you must remember that 1 equals 100% and that what you must do is multiply the number by 100 and add the symbol% at the end.

[tex] \bold{1 /25 * 100 = 0.04 * 100 = 4\%}[/tex]

And finally we have:

Answer:

B

Step-by-step explanation:

elimination

4x - y = 8

6x + y = 2

--------------- +

10x = 10

x = 1

since x = 1, we can subtitute x to one of those equations

4x - y = 8

4(1) - y = 8

4 - 8 = y

y = 4 - 8

y = -4

x,y = 1,-4

Answer:

B is correct

Step-by-step explanation:

you add the two equations together. So 4x + 6x  equals what? 10x. we know that y and -y cancel each other out. and then we all know that 8+2 is 10. now we have 10x=10 so x=1. We replace x for one and then we have 4 - y =8 so y has to equal -4 and there you have your answer, b
