Step-by-step explanation:
Given:
Amount of of lemonade available = 20⅜ cups
Amount of lemonade per guest = 1½ cups

Number of glasses to be filled
SOLUTION:
Number of glass to be filled = amount of lemonade available ÷ amount of lemonade per guest
= 20⅜ ÷ 1½
Change both mixed fractions to improper fractions
= [tex] \frac{163}{8} [/tex] ÷ [tex] \frac{3}{2} [/tex]
Flip the fraction on your right upside down and change the division to multiplication
[tex] = \frac{163}{8} * \frac{2}{3} [/tex]
[tex] = \frac{163*2}{8*3} [/tex]
[tex] = \frac{163*1}{4*3} [/tex]
[tex] = \frac{163}{12} = 13.58 [/tex]
Number of glasses that would be filled is roughly 13 glasses.
A self-serve car wash charges $5.20 to use its facilities, plus an additional $0.66 for each minute the customer is at the self-serve car wash. If Tiffany was at the car wash for 9 minutes, how much was she charged?
A.$11.14
B.$14.20
C.$5.94
D.$5.86
The required amount charged to Tiffany for 9 minutes of the car wash is $11.14. Option A is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The additional charge for the time Tiffany was at the car wash was $0.66 per minute, so the total charge for 9 minutes would be
= $0.66 * 9
= $5.94.
Adding this to the original charge of $5.20 gives a total charge,
= $5.20 + $5.94
= $11.14.
Therefore, Tiffany was charged A) $11.14.

Nash is training for a marathon and decides to train for 26 miles every week. In the first week, the ratio of the number of miles he ran to the number of miles he walked 3:10. In the fifth week the ration ran to walked is 8:5. How many miles did nash run in week 5
Answer:
16 miles
Step-by-step explanation:
From the question given above, the following data were obtained:
Miles per week for training = 26 miles.
In the 5th week:
Ratio of miles ran to miles Walked is 8:5
Thus, we can obtain the miles ran by Nash in the 5th week as follow:
Ratio ran = 8
Ratio walked = 5
Total ratio = 8 + 5 = 13
Miles per week for training = 26 mile
Mile ran in the 5th week = 8/13 × 26
Mile ran in the 5th week = 8 × 2
Mile ran in the 5th week = 16 miles
Therefore, Nash ran 16 miles in the 5th week of training.
