17. The answer should be 17
Answer:
4 movies, $20
Step-by-step explanation:
Given data
Family Video
charges $10 for a monthly membership and
$2.50 per movie
let the number of movies be x
and the charge for x movies be y
y= 10+2.5x----------1
Babe's Movies
charges a $12
membership and $2 per
movie.
let the number of movies be x
and the charge for x movies be y
y= 12+2x----------2
equate 1 and 2
10+2.5x= 12+2x
collect like terms
12-10= 2.5x-2x
2= 0.5x
x= 2/0.5
x= 4 movies
put x= 4 in equation 1 or 2
y= 12+2x----------2
y= 12+2*4
y= 12+8
y= $20
Answer:
The length of legs lm, mn, and lk is 32 while that of kn is 36.
Step-by-step explanation:
The diagram is attached in the answer.
As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk
This leads the two set of legs such as

Or this could be written as

Now the remaining two sides are given as
as this form an isosceles triangle so

Similarly

Or

Now the perimeter is given as

Here perimeter is given as 132 so this gives:

So the four legs are of length as given below:

So the length of legs lm, mn, and lk is 32 while that of kn is 36.
To find an area of a parallelogram is by multiplying the b and h to get 1095.2
Answer:
4/25
Step-by-step explanation:
12 divided by 3
72 divided by 3
Greatest Common Divisor:
3
So 12/72 simplifed would be 4/25 and the GCD would be 3.
