Answer:
B: 25%
Step-by-step explanation:
$90.00 - $67.50 = $22.5
$22.5 / $90 = 0.25 = 25%
Answer:
B: 25%
Sin C = AB / AC
We have AC. We need to calculate AB
ABC is a right triangle. Therefore, AC² = AB²+BC²
82² = AB ² + 80² => AB² = 82² - 80²
AB = 18
Sin C = 18/82 = 9/41
Good luck
Answer:
20 band posters
Step-by-step explanation:
Set up a proportion where x is the number of band posters she should sell:
=
Cross multiply and solve for x:
2400 = 120x
20 = x
So, she should sell 20 band posters.
If she sells 20 band posters and 24 movie posters, the ratio will be 96:80, which is the same as 120:100. Simplified, both ratios are 1.2:1
Hello,
Choice urn_1: 1/3
choice R: 5/8 ==>1/3*5/8=5/24
Choice urn_2: 1/3
Choice R: 3/4 ==> 1/3*3/4=1/4
Choice urn_3: 1/3
Choice R:4/6=2/3 ==> 1/3*2/3=2/9
Total: 5/24+1/4+2/9=15/72+18/72+16/72=49/72
