Mathematics
1 answer:
Nana76 [90]3 years ago
4 0

Answer:

Time left for each question is less than 5.5 minutes

Step-by-step explanation:

Given that:

Raphael is trying to solve 5 math questions in less than 20 minutes.

3 questions have been completed which have taken 3 minutes each.

To find:

How much time is left with Raphael for each question so as to reach his goal.

Solution:

First of all, let us find the time that has been already consumed by Raphael in solving the 3 questions.

3 \times 3 = 9 minutes

Time left = Total Time - Time already consumed

Time left = 20 - 9 = 11 minutes

Number of questions to be solved = Total questions - Questions solved

Number of questions to be solved = 5 - 3 = 2

Average time left for each question = Time left divided by Number of questions to be solved

Average time left for each question = 11 \div 2 = 5.5 minutes

Therefore, time left for each question is less than 5.5 minutes.

At the city museum, child admission is $5.20 and adult admission is $8.90 . on friday, 159 tickets were sold for a total sales o
Zinaida [17]
Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90

Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80

Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70

$273.80 ÷ $3.70 = 74 adult tickets

159 - 74 = 85 child tickets
