Answer:
Proportions:
18/8 and 9/4
4/7 and 10/17.5
<em>Everything else is not a proportion</em>
Step-by-step explanation:
To find if two fractions are a proportion, we need to set each up as a fraction. Then, we multiply both diagonal values. If we get the same value, they are proportionate.
and :
So these aren't proportionate.
and :
So these aren't proportionate either.
and :
So this is proportionate.
(since 775 is just that over 1) and :
So this isn't proportionate.

<span>The
box office manager said that 5000 people attended the show.
Find the possible actual number of people who attended the show if he convert
it to the nearest hundred.
=> 5 000 = 5 thousands, 0 hundreds, 0 tens, 0 ones.
=> x xxx = actual number of people
who attended the show
=> x xxx = may be the actual number is 4 990 or more because he rounded the
number to it’s nearest hundreds.
=> 4 990 , hundredths place has a value of 9 and the next digit also has a
value of 9
thus when you round it, it will become 5000.

Answer:
C. 56.25π cm²
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
15 pi = 2 * pi *r
Divide each side by pi
15 = 2r
Divide by 2
15/2 = 2r/2
7.5 = r
We want to find the area
A = pi r^2
A = pi (7.5)^2
A = pi *56.25
A = 56.25 pi
