Would some please check these and see if I am doing them right thank you

1. Gasoline is about $2 per gallon. You use about 1 1/2 gallons each day driving to and from work. How much should you budget for gasoline over the next month (about 20 workdays)?

Answer 1 1/2 x $2.00 = $3.00 a day
20 day x $3.00= $60.00

2.Four buttons have diameters of 5/8 , 3/4 ,9/16 , and 7/8 inches. Which button is smallest?
Answer: B) 9/16

3. If the base of a parallelogram is 6 1/2 in. and its height is 1 1/2 in., what is its area?

6 1/2 x 1 1/2 = 13/2 x 3/2 = 39/4= 9 3/4

4. A triangle has base 15 feet (ft) and an altitude of 4 ft. Find its area.

1/2 x 4ft x 15ft= 30ft^2

5. The circular surface of a table has a diameter of 4 ft. What it will cost to have the top refinished if the company charges $5 per square foot for the refinishing? Use 3.14 for piƒnand round your answer to the nearest cent.

A= 3.14 x 4ft/2^2
3.14 x 12^2
3.14 X 24
75.36ft

Please do not double-post the same questions

1. Gasoline budget: To find out how much you should budget for gasoline over the next month, you need to calculate the total cost of gasoline for 20 workdays. Given that you use 1 1/2 gallons each day and gasoline costs $2 per gallon, the daily cost is 1 1/2 x $2.00 = $3.00. Now you can multiply the daily cost by the number of workdays in a month (20) to get the total cost: 20 days x $3.00 = $60.00. Therefore, you should budget $60.00 for gasoline over the next month.

2. Smallest button: To determine which button is the smallest, compare their diameters. Given that the buttons have diameters of 5/8, 3/4, 9/16, and 7/8 inches, you can visually inspect and compare the fractions. In this case, the button with a diameter of 9/16 inches (option B) is the smallest. Hence, the answer is B) 9/16.

3. Parallelogram area: To find the area of a parallelogram, multiply the length of the base by the height. Given that the base is 6 1/2 inches and the height is 1 1/2 inches, you can multiply these values: 6 1/2 x 1 1/2 = 13/2 x 3/2 = 39/4 = 9 3/4. Therefore, the area of the parallelogram is 9 3/4 square inches.

4. Triangle area: To calculate the area of a triangle, multiply half the base by the altitude. Given that the base is 15 feet and the altitude is 4 feet, you can calculate the area as follows: 1/2 x 4 feet x 15 feet = 30 square feet. Hence, the area of the triangle is 30 square feet.

5. Table refinishing cost: To determine the cost of refinishing the circular surface of the table, you need to calculate the area of the circle. Given that the diameter is 4 feet, you can use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius (which is half the diameter). So, the radius is 4 feet/2 = 2 feet. The area can then be calculated as A = 3.14 x (2 feet)^2 = 3.14 x 4 feet = 12.56 square feet. Since the company charges $5 per square foot, you can multiply the area by the cost per square foot: 12.56 square feet x $5 = $62.80. Rounded to the nearest cent, it will cost approximately $62.80 to have the top of the table refinished.
