Answer:
136
Step-by-step explanation:
7*5=35
35+35=70
1/2*6*4=12
12+12=24
6*7=42
70+42+24=136
sorry if it is wrong.
The answer is 25 13/20 square feet.
In order to complete this operation, it is first best to change your mixed numbers into improper fractions.
7 1/8 = 57/8
7 1/5 = 36/5
Now that we have these, we can put them into the triangle formula.
A = 1/2bh
A = (1/2)(57/8)(36/5)
A = 1026/40
You can then simplify this fraction by dividing the top and bottom by a factor of 2.
A = 513/20
Then, because we know 20 goes into 500, 25 times, we can pull that out and be left with a remainder of 13/20.
A = 25 13/20
A) 5 to be chosen among a Total : 10 Men + 8 Women
¹⁸C₅ = (18!)/(5!)(13!) = 8,568 groups of five
b) A must to have men and women. If so we have to deduct all groups of 5 that are all men and all group of 5 that are all women
Groups of 5 with only men: ¹⁰C₅ = 252
Groups of 5 with only women: ⁸C₅ = 56
So number of committees of 5 men and women mixed =
8568 - 252 - 56 = 8,260 committees
c) 3 Women and 2 Men:
⁸C₃ x ¹⁰C₂ = 2,520 groups of 3 W and 2 M
d) More women than men, it means:
3 W + 2 M OR (we have found it in c) = 2,520)
4 W + 1 M OR ⁸C₄ x ¹⁰C₁ →→→→ = 700
5 W + 0 M OR ⁸C₅ x ¹⁰C₀ →→→→ = 56
Total where W>M = 3,276 groups of 5 where women are at least 3
Given;
40 fluid ounces of iced tea.
We know,
1 cup = 8 fluid ounce
1 pint = 2 cup
Now,
8 fluid ounce = 1 cup
1 fluid ounce = 1 / 8 cup
40 fluid ounce = (1 / 8) * 40 cup
So, 40 fluid ounce = 5 cup
Now,
We, used 3 cups of iced tea. So, we only have 2 cups of iced tea left.
We have,
2 cups = 1 pint
So, 1 pint of iced tea is left!
