For the roof of the shelter, Mia has a board that measures 1 square yard, a second
board that measures 3 feet by 3 feet, and a third board that measures 36 inches by
36 inches.
Which of the boards, if any, will cover all the space needed for the roof? Explain your
answer, drawing a picture if necessary.
1 foot = 1/3 of a yard.
First, let's convert all the measurements to the same unit. We know that 1 yard is equal to 3 feet and 1 foot is equal to 1/3 of a yard.
The first board measures 1 square yard. Since 1 yard is equal to 3 feet, the first board can also be said to measure 3 feet by 3 feet.
The second board measures 3 feet by 3 feet.
The third board measures 36 inches by 36 inches. Since 1 foot is equal to 12 inches, the third board can also be said to measure 3 feet by 3 feet.
Therefore, both the first board and the third board measure 3 feet by 3 feet, which is the same as the second board.
Therefore, all three boards will cover all the space needed for the roof.
$15.20 + 5%
To find 5% of $15.20, we can multiply $15.20 by 0.05:
$15.20 * 0.05 = $0.76
Adding $0.76 to $15.20 gives us the final result:
$15.20 + $0.76 = $15.96
Li earns $30 each week mowing lawns in her neighborhood. She puts 60% of her
earnings into her savings account at the end of each month. How much money
does Li deposit into her account each month? Show your work.
To find out how much money Li deposits into her account each month, we need to calculate 60% of her monthly earnings.
We know that Li earns $30 each week, and there are 4 weeks in a month (approximately).
$30/week * 4 weeks = $120/month
Next, we need to find 60% of $120:
60/100 * $120 = $72
Therefore, Li deposits $72 into her savings account each month.
60 divided by 100
To divide 60 by 100, you just need to divide 60 by 100 and express the result as a decimal or fraction.
60 ÷ 100 = 0.6
Therefore, 60 divided by 100 is equal to 0.6.
100 divided by 60
To divide 100 by 60, you divide 100 by 60 and express the result as a decimal or fraction.
100 ÷ 60 = 1.6667 (rounded to four decimal places)
Therefore, 100 divided by 60 is approximately 1.6667.
After saving $250, Li invests in a certificate of deposit (CD) that pays 2.6% annual
interest. What will be the value of Li’s CD after she has had it for one year? Show
