Assuming they will all pay equaliy, including the tip,
100=orignal
100+20=120
120% of 62.50
ssimlify it
120/4=30
30% of 62.50=0.3*62.5=18.75
each person pays $18.75
We know that the total number of students is 180, so 180 is the 100 precent of the students, now we can set up a proportion and solve
180/100=135/x
x=135 times 100 over 180
x=75%
Answer:
NO this set is not equivalent
Step-by-step explanation:
Okay the way you find out if a pair of ratios are equal is you would divide the denominator and nominator with each other, so: 13/7 and 9/4. But sense the answer would be in decimal form and cant be simplified this wouldnt be considered equivalent. Also if you divide 7 by 4 you get a different answer than when you do 13 divided 9.
The polygon would have 24 sides. (n-2)180 = n =24
Do 7/8 divided by 3/16.
Multiply by the reciprocal of 3/16 which is 16/3
7/8 x 16/3= 112/24
Simplify by dividing by 8 on top and bottom
14/3
Change it into a mixed number
Answer is 4 2/3
