Tom and Jim are distant cousins who meet during their family Thanksgiving meal. Tom tells Jim that he has 3 kids, and the product of their ages is 72. He also tells him the sum of their ages. Jim says he still can’t correctly guess the ages of Tom's kids. Finally, Tom says, "My youngest child's name is Joy." Jim can then correctly guess. What are the ages?

Answers

Answer 1

Answer:

6, 6, 2

Step-by-step explanation:

Factor 72:

72 = 2³ × 3²

Look for groups of 3 numbers whose products are 72 and their sums:

2, 4, 9: sum 15

8, 9, 1: sum 18

8, 3, 3: sum 14

6, 6, 2: sum 14

6, 4, 3: sum 13

12, 6, 1: sum 19

12, 3, 2: sum 17

18, 4, 1: sum 23

18, 2, 2: sum 22

24, 3, 1: sum 28

36, 2, 1: sum 39

72, 1, 1: sum 74

Jim knows the sum, but he can't guess the ages. that means the sum must be 14 for which there are two sets of ages which have a product of 72:

8, 3, 3 and 6, 6, 2

Then when he says "my youngest", that means one age is less than the other two. The only choice is 6, 6, 2.

The probability that a randomly selected single parent in the U.S. military is a woman in the Air Force is [tex]\( \frac{6}{97} \)[/tex], which is approximately 0.0619 or 6.19%.

To find the probability that a randomly selected single parent in the U.S. military is a woman in the Air Force, we need to divide the number of women in the Air Force by the total number of single parents in the military.

1. First, find the number of women in the Air Force from the table. This is given as 6 thousand.

2. Next, find the total number of single parents in the military. This is given as 97 thousand.

3. Finally, divide the number of women in the Air Force by the total number of single parents in the military and express the result as a fraction or decimal to represent the probability.

So, the probability P can be calculated as:

[tex]\[ P = \frac{{\text{Number of women in the Air Force}}}{{\text{Total number of single parents}}} \][/tex]

Substituting the values:

[tex]\[ P = \frac{6}{97} \][/tex]

[tex]\[ P ≈ 0.0619 \][/tex]

Therefore, the probability that a randomly selected single parent in the U.S. military is a woman in the Air Force is approximately 0.0619 or 6.19%.

A theater can seat 144 people. The number of rows is 7 less than the number of seats in each row. How many rows of seats are there?

Answers

Final answer:

To determine the number of rows in the theater, we use the given information to create the equation x * (x - 7) = 144 where x is the number of seats per row. Factoring out, we find 16 and 9 as a suitable pair, leading to the conclusion that there are 9 rows of seats in the theater.

Explanation:

The student's question involves finding the number of rows of seats in a theater given certain constraints. To solve this problem, let's designate x as the number of seats in each row. According to the question, the number of rows of seats is 7 less than the number of seats in a row, which can be written as x - 7. Since we know the theater can seat 144 people in total, we can create the following equation to represent the total number of seats:

x  imes (x - 7) = 144

Solving this quadratic equation by factoring will give us the value of x, which will then allow us to calculate x - 7 for the number of rows. By factoring 144, we find that 16 and 9 are factors that satisfy the equation (16  imes 9 = 144) and also meet the condition that one factor is 7 less than the other (16 - 7 = 9). Therefore, the number of seats in each row is 16, and the number of rows is 16 - 7 which gives us 9 rows in the theater.

A rectangle has a length of 32 yards less than 3 times its width. If the area of the rectangle is 748 square yards, find the length of the rectangle.

Answers

I hope this helps you

The length of the rectangle will be 34 yards.

What is the area of the rectangle?

The space occupied by any two-dimensional figure in a plane is called the area. The two-dimensional space occupied by the rectangle is called the area of the rectangle.

Given that A rectangle has a length of 32 yards less than 3 times its width. If the area of the rectangle is 748 square yards. The length and the width will be calculated by forming an expression.

Area = L x W

Area = W ( 3W - 32 )

748 = 3W² - 32W

3W² -32W -748 = 0

W = 22 and W = -11

The width will be 22 yards put W in the expression of L to get L.

L= ( 3W - 32 )

L = ( 3 x 22 - 32 ) = 34 yards

Therefore, the length of the rectangle will be 34 yards.

Janelle bought a pair of sneakers for $75.65. There was a 15% discount. What was the original price of the sneakers?

Answers

The original price of the sneakers was $87.

To determine the original price of Janelle's sneakers, we calculate the inverse of the 15% discount that left her with a final price of $75.65, revealing the original price to be $89.00.

To find the original price of the sneakers that Janelle bought with a 15% discount, we need to understand that the final price after the discount represents 85% of the original price. This is because a 15% discount reduces the original price by 15%, leaving us with 100% - 15% = 85% of the original price. Janelle's sneakers cost her $75.65 after the discount.

Let's denote the original price by x. Therefore, 85% of x is equal to $75.65. We can set up an equation to represent this relationship:
0.85x = $75.65

To find x, we divide both sides of the equation by 0.85:
X = $75.65 / 0.85
x = $89.00

Thus, the original price of the sneakers was $89.00 before the 15% discount.

A scientist is working with 0.9m of gold wire. How long is the wire in millimeters?

Answers

900
I hope this helps with whatever your doing

Answer:

The length of the wire in millimeters is 9 × 10² mm.

Step-by-step explanation:

1 meter is equal to 1000 millimeters. This is the ratio that we use to convert a length in meters to one in millimeters. A scientist is working with 0.9 m of gold wire. We will use a conversion fraction to express this number in millimeters.

0.9 m × (1000 mm/ 1 m) = 900 mm = 9 × 10² mm (we round off to 1 significant figure)

The length of the wire in millimeters is 9 × 10² mm.

Find the x-intercepts of the parabola with vertex (-3,-18) and y-intercept at (0,0)

Answers

y + 18 = a(x + 3)^2 
0 + 18 = a(0 + 3)^2 
18 = 9a 
2 = a 

y = 2(x + 3)^2 - 18 
0 = 2(x + 3)^2 - 18 
18 = 2(x + 3)^2 
9 = (x + 3)^2 
± 3 = x + 3 
-3 ± 3 = x 
x = 0 or -6 

(0, 0) and (-6, 0)
Final answer:

To find the x-intercepts of the parabola given its vertex and y-intercept, we can first determine the equation of the parabola. Then, we set y equal to zero and solve for x. In this case, the x-intercepts are 0 and -6.

Explanation:

The x-intercepts of a parabola can be found by setting the y-coordinate to zero and solving for x. The vertex form of a parabola is given by y = a(x - h)^2 + k, where (h, k) is the vertex. In this case, the vertex is (-3, -18), so the equation of the parabola is y = a(x + 3)^2 - 18. Since the y-intercept is at (0, 0), we can substitute these values into the equation to solve for a. Plugging in the values gives: 0 = a(0 + 3)^2 - 18. Solving for a, we get a = 2. Therefore, the equation of the parabola is y = 2(x + 3)^2 - 18. To find the x-intercepts, we set y equal to zero and solve for x: 0 = 2(x + 3)^2 - 18. Simplifying, we have 2(x + 3)^2 = 18. Dividing both sides by 2 gives (x + 3)^2 = 9. Taking the square root of both sides, we get x + 3 = ±3. Solving for x gives the x-intercepts as x = 0 and x = -6.

y = mx + b
slope(m) = 8/9

Since bank charges are deductions from the bank statement balance, the correct answer is:

B. a deduction from the balance per bank statement.

When reconciling a bank statement with the company's books, bank charges are typically deducted from the balance per bank statement.

Let's break down the process:

1. Balance per bank statement: This is the ending balance reported by the bank on the statement.

2. Additions to the bank statement balance: These are items such as deposits in transit (deposits made but not yet recorded by the bank), interest earned, or other credits.

3. Deductions from the bank statement balance: These are items such as outstanding checks (checks issued by the company but not yet cleared by the bank), bank fees or charges, and NSF (non-sufficient funds) fees.

We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we cannot dedicate -- we cannot consecrate -- we cannot hallow -- this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.
