Math Problem Statement
Solution
Let's go through the problems in the image one by one.
Problem 11:
The boiling point of water is 212°F. In degrees Celsius, how much will that 165°F water increase to boil?
To solve this, we use the formula: where is the temperature in Celsius and is the temperature in Fahrenheit.
-
Convert 212°F to Celsius:
-
Convert 165°F to Celsius:
-
Find the difference:
The answer is approximately 26°C.
Problem 12:
A small theater sold 72 tickets for a play. The ratio of adult tickets to child tickets was 4:1.
- Part A: Draw a diagram and make a table to represent the types of tickets sold.
Let's assume is the number of child tickets. Since the ratio is 4:1, the number of adult tickets would be . The total number of tickets sold is: However, since ticket numbers must be whole numbers, let's consider:
- Child tickets
- Adult tickets
This calculation needs to be adjusted or clarified since fractional tickets aren't realistic. The correct integer distribution should be calculated with the correct ratio adjustments. I recommend rechecking this since the correct sum needs to match 72.
- Part B: The diagram should visually depict the tickets sold.
Problem 13:
Use the given set of coordinates to write the reflection across the y-axis of each point on the left.
For each point , the reflection across the y-axis is .
So, the reflected coordinates are .
Problem 14:
The drama club spent $608 on food for a party. If there are 15 members and each paid an equal amount, how much did each member pay?
-
Part A: Write an equation:
-
Part B: Solve the equation:
Each member paid approximately $40.53.
Problem 15:
Complete the Venn diagram to show the common factors of 63 and 45. Then circle the greatest common factor.
The factors are:
- 63:
- 45:
Common factors: .
The greatest common factor is 9.
