Answer:
12 problems
Step-by-step explanation:
All problems were of equal value
Let x be the number of problems in the test
We apply a rule of three
x ------------------------------- 100%
(x-10) --------------------------- 17%
(x-10)*100%/(x) = 17%
(x-10)/(x) = 0.17
(x-10) = 0.17*x
0.83*x = 10
x = 12.05
x = 12 problems
The ratio of a pair of corresponding sides of 1/16.
Answer:
8
Step-by-step explanation:
The median is the middle of the data when it is put from smallest to largest
9, 6, 7, 3, 10, 9
3,6,7,9,9,10
The middle is between the 7 and the 9
We will add the 7 and the 9 and divide by 2
7+9 = 16
16/2

= 75/3
= 25
Hence the bottle will hold 25 ounces of water
