Answer:
45 meals.
Step-by-step explanation:
Each meal takes up 2/3 pounds. To find the answer, divide how much Rita bought, 30, by how much is consumed each meal.
30/(2/3)=45
For 20 months, Molly deposited $86.50, so she deposited a total of 86.5 * 20, namely 1730 bucks.
now, every month she deflated her account by $24.50 to pay for her singing lessons, she did that every month, namely for 20 months so she deflated the account balance by 24.5 * 20, or 490 bucks.
so, she deposited 1730 and deflated it by 490, 1730 - 490 = 1240, that's all that's left in the account.
for the Summer Camp, she spent 1/4 of that, what's a quarter of that? well is just their product, (1/4) * 1240.
Answer:
15/322
Step-by-step explanation:
There are 12 tests of test A, and there are 12 tests of test B.
For the student to get A, it is a 12/24 chance.
For the next student, it is a 11/23 chance
For the next 10/22
For the next 9/21
12/24*11/23*10/22*9/21=15/322
15/322 chance
Length = 31 ft
width = 19 ft
Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12
The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w
Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.
Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft
Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft
