Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. What is the equation that can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?

y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
y=20x+2; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=20x +2; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.

A survey of 1250 trees in a small wood showed that 32 percent were oak trees 26 percent were birch trees and the remainder were pine trees how many pine trees were there

Answers

Answer: There were 525 pine trees.

Step-by-step explanation:

Given: Total trees = 1250

Percentage of oak trees = 32%

Percentage of birch trees = 26%

Since remaining trees are pine trees.

Percentage of pine trees = 100% - 32% - 26%

=42%

The number of pine trees = 42% of 1250

= 0.42 ×1250

= 525

Hence, there were 525 pine trees.

The Wilson Student Government sold $ 126 worth of tickets for a talent show in 3 hours. How many tickets did they sell in one hour?

Answers

Answer:

Step-by-step explanation:

They sold $42 worth of tickets in one hour. Need more information to determine the number of tickets.

The Wilson Student Government sold $42 worth of tickets in one hour. Total amount of money earned from ticket sales = $126

Number of hours during which the tickets were sold = 3 hours

Step 1: Divide the total amount of money earned by the number of hours to find the average ticket sales per hour.

Tickets sold in one hour = Total amount of money / Number of hours

Tickets sold in one hour = $126 / 3

Step 2: Perform the division.

Tickets sold in one hour = $42

So, the Wilson Student Government sold $42 worth of tickets in one hour. This means that on average, they were making $42 per hour during the three-hour period of selling tickets for the talent show.
