The research shows that the name of the ferris wheel is <u>The London Eye</u> and the diameter of the wheel is 120m.

<h3>What is a research?</h3>

A research is simply carried out to get information about a particular topic or issue.

In this case, the research was conducted on the ferris wheel. The number of cars or compartments is 32.

The circumference of the wheel will be:

= 2πr

= 2π(120/2)

= 377m

The area of the wheel will be:

= πr²

= π(60²)

= 11310m²

The measure of a central angle in degrees will be:

= 360/32 = 11.25 degrees

The measure of a central angle in radians will be:

= 2π(11.25)/360

= 20 radians.

The arc length between two cars or compartments will be:

= 2π(60)(11.25)/360

= 11.78

The area of a sector between two cars or compartments will be:

= π(60²)(11.25)/360

= 353.43

An equation of a circle for your ferris wheel when the center of the ferris wheel is located at (0, 0) on a coordinate grid will be x² + y² = 3600.

Ryan works at at the donut shop where he makes $10.25 per hour . He also works part time at the school bookstore where he makes
SCORPION-xisa [38]

Answer:

6 hours

Step-by-step explanation:

Let

x----> the number of hours worked at the donut shop

y----> the number of hours worked at the school bookstore

we know that

x+y=20

x=20-y -----> equation A

10.25x+8.75y=196 -----> equation B

Substitute equation A in equation B and solve for y

10.25(20-y)+8.75y=196

205-10.25y+8.75y=196

10.25y-8.75y=205-196

1.5y=9

y=6 hours at the school bookstore

If x – 10 is a factor of x2 – 8x – 20, what is the other factor?
Svetach [21]

Answer:

The other factor is (x+2)

Step-by-step explanation:

we know that

(x-a)(x-b)=x^{2}-xb-xa+ab

(x-a)(x-b)=x^{2}-(a+b)x+ab

In this problem we have

x^{2} -8x-20

and

a=10 -----> because is a factor

substitute and solve for b

x^{2} -8x-20=x^{2}-(10+b)x+10b

so

8=10+b\\b=-2

Verify in the second equation

-20=10b -----> -20=10(-2) -----> -20=-20--> is ok

The other factor is (x+2)
