Answer:
180 degree rotation
Step-by-step explanation:
according to the picture, we can see the wheel made half of a full rotation before it stopped. a full rotation of a circle is 360 degrees, so the car made a rotation of half of 360, which is 180 degrees.
let's check our work!
a full ride on a ferris wheel is two full rotations, which is 720 degrees. Maria rode for 1/4 of a turn which we solved for 180 degrees.
180 x 4 = 720 degrees.
our answer is correct
There were 151 at the morning service and 115 at the evening service<span />
300 jelly beans cost you x dollars.
if you divide 300 by x, you get the number of jelly beans per dollar.
now you are buying 1/2 a dollar's worth of jelly beans, so you will be getting 1/2 * 300 / x which is equal to 150 / x jelly beans.
the actual number of jelly beans you get is determined by x.
if x = 1, the you get 150 jelly beans for 1/2 of a dollar.
if x = 3, then you get 50 jelly beans for 1/2 of a dollar.
you can also work this out by determing the cost per jelly bean.
if you pay x dollars for 300 jelly beans, then the cost per jelly bean is equal to x/300.
now you want to buy 50 cents worth of jelly beans.
the number of jelly beans you can buy is the money you pay divided by the cost per jelly bean.
you pay 50 cents which is equal to 1/2 of a dollar.
you will get 1/2 / (x/300) which is equal to ((1/2)*300)/x which is equal to 150/x.
now let's assume x is equal to 1.
you will get 150/1 = 150 jelly beans.
now let's assume x is equal to 3.
you will get 150/3 = 50 jelly beans.
the equation becomes:
number of jelly beans = 150/x
x = cost for 300 jelly beans.
it's just a matter of how you want to look at it.
another way to look at it would be to set up a ratio.
the ratio would be:
300/x = y/.5
this ratio says:
300 jelly beans is to x dollars as y jelly beans is to half a dollar.
cross multiply to get:
.5*300 = x*y
simplify to get:
150 = x*y
divide both sides of the equation by x to get:
y = 150/x
same equation again.
x is the cost for 300 jelly beans.
y is the number of jelly beans you can get for half a dollar.
Given:
Big figure = 20 ft
Small figure = 7 ft
Take note: In finding the scale factor, we must make sure that the measurements of both figures are the same sides or line.
20 feet / 7 feet = 2.86 scale factor.
This means that the big figure is 2.86 times bigger than the small figure.
If the arrow had been pointed from the small figure to the big figure.
7 feet / 20 feet = 0.35 scale factor.
This means that the small figure is only 0.35 of the big figure.
Both are scale factors but in different perspectives.
