Each week as part of her workout, Monica walks 0.5 mile, runs 1.6 miles, and then walks 0.75 mile.
How many total miles will Monica walk and run in a year? Reminder: there are 52 weeks in a year.
Enter your answer in the box.
Answer: 148.20 miles
Step-by-step explanation:
From the question, we are informed that every week as part of her workout, Monica walks 0.5 mile, runs 1.6 miles, and then walks 0.75 mile.
The total miles will Monica walk and run in a year will be calculated as:
Total miles walked in a week = 0.5 + 0.75 = 1.25 miles
Total miles run in a week = 1.6 miles
The total miles Monica walk and run in a year will then be:
= (1.25 + 1.6) × 52
= 2.85 × 52
= 148.20 miles

Step-by-step explanation:
a small water bottle holds 75% as much as a large water bottle.
if the small holds 36 units, how much does the large hold?
Capacity of larger bottle = 48 units
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given,
small bottle holds 36 units of water
Let the large bottle holds x units of water
According to the question,
capacity of small bottle = 75% of capacity of large bottle
36 = 75/100 × x
⇒ x = 36 × 100 / 75
⇒ x = 3600/75
⇒ x = 48 units
Hence the larger bottle holds 48 units of water.

The school that Eduardo goes to is selling tickets to a fall musical. On the first day of ticket salesthe school sold 3 adult tickets and 7 student tickets for a total of $81. The school took in $94 onthe second day by selling 4 adult tickets and 7 student tickets. Find the price of an adult ticketand the price of a student ticket.A) adult ticket: $6, student ticket: $13B) adult ticket: $13, student ticket: $6C) adult ticket: $17, student ticket: $9D) adult ticket: $19, student ticket: $8
Answer: B) adult ticket: $13, student ticket: $6
Step-by-step explanation:
Let adults tickets be written as a
Let student tickets be written as s
We then use the information given in the question to form equation. This will be:
3a + 7s = 81 .......... equation i
4a + 7s = 94 .......... equation ii
Subtract equation i from ii
a = 13
Adult tickets cost $13
From equation i
3a + 7s = 81
We put the value of a = 13
3(13) + 7s = 81
39 + 7s = 81
7s = 81 - 39
7s = 42
s = 42/7
s = 6
Students ticket cost $6
