Answer:

45 adults, 30 boys, 105 girls

Step-by-step explanation:

Adults --- 3 units

Boys --- 2 units

Girls --- 7 units

Total

= 3 +2 +7

= 12 units

Since there are 180 people in total,

12 units --- 180 people

1 unit --- 180 ÷12= 15 people

Number of adults

= 3(15)

= 45

Number of boys

= 2(15)

= 30

Number of girls

= 7(15)

= 105

An item is priced at $14.74. If the sales tax is 4%, what does the item cost including sales tax? A. $20.64 B. $15.33 C. $0.59 D
otez555 [7]
The question already has all the information's that are required for getting to the solution. It is important to minutely look at all the details provided.
Actual price of the item = $14.74
Percentage of sales tax that needs to be added = 4%
Then
Amount of sales tax that needs to be added = (4/100) * 14.74 dollars
                                                                       = 58.96/100 dollars
                                                                       = 0.5896 dollars
                                                                       = 0.59 dollars
Then
The cost of the item including sales tax = (14.74 + 0.59) dollars
                                                                 = 15.33 dollars
From the above deduction we can easily conclude that the correct option among all the options given in the question is option "B".

Please help me with this.A rectangular field is
Karolina [17]
First, let's get the perimeter of the rectangle:
P=2W+2L
P=130m+210m
P=340m
Then, let's get the area of the bigger one:
A=WL
A=65m*105m
A=6825m^2

Then let's try using a rectangle with a smaller ratio:
P=100m+240m
P=340m
Then:
A=50m*120m
A=6000m^2

If you used a square:
P=170+170
P=340
A=WL
A=85^2
A=7225

There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.

At a certain charity fundraiser, some guests will be randomly selected to receive a gift. The probability of receiving a gift is
mixas84 [53]

Answer:

a) Your answer for part a (I got 3/28) is wrong.

Odds are always expressed as ratios after calculating. Therefore, the odds in favour of receiving a gift = 3:22

b) Your answer in part b(I got 7/9) is correct.

The probability of the box having a toy is 7/9.

Step-by-step explanation:

The question above has to do with odds and probability.

It is important to note that odds are expressed in the form of ratios while probabilities are expressed as fractions.

a) At a certain charity fundraiser, some guests will be randomly selected to receive a gift. The probability of receiving a gift is 3/25. Find the odds in favor of receiving a gift.(I got 3/28)

The formula for calculating odds from probability is Odds = Probability / (1 - Probability).

Probability = 3/25

Odds =(3/25)/(1 - 3/25)

= (3/25)/22/25

= 3/25 ÷ 22/25

= 3/25 × 25/22

= 3/22

Note that odds are always expressed as ratios.

Therefore, the odds in favour of receiving a gift = 3:22

Your answer for part a (I got 3/28) is wrong.

The correct answer is 3:22

b) A child has a box of candies which might have a toy inside. The odds against the box having a toy are 7/2. What is the probability of the box having a toy? I got 7/9.

The formula for calculating probability from odds is P = Odds / (Odds + 1).

Odds = 7/2 or 7:2

We convert the odds to fraction when calculating

Probability = Odds / (Odds + 1).

Probability = (7/2)/ (7/2 + 1)

Probability = (7/2)/9/2

Probability = 7/2 ÷ 9/2

= 7/2 × 2/9

= 7/9

Probability is always expressed as a fraction.

Therefore, the probability of the box having a toy is 7/9.

Your answer in part b(I got 7/9) is correct.
