Final answer:

To find the sine of angle ABC, we need to first find the length of the arc BC, which is equal to the circumference of the resulting cylinder. The circumference can be found by multiplying the diameter of the rhombus, which is equal to the length of side AB, by π (pi). In this case, the circumference is 6π. Using the length of the arc, BC, and the radius of the cylinder, we can find the angle ABC using the formula θ = s/r, where θ is the angle in radians, s is the length of the arc, and r is the radius of the cylinder.

Explanation:

To find the sine of angle ABC, we need to first find the length of the arc BC, which is equal to the circumference of the resulting cylinder. The circumference can be found by multiplying the diameter of the rhombus, which is equal to the length of side AB, by π (pi). In this case, the circumference is 6π. Since the volume of the cylinder is given as 6, we can use the formula V = πr^2h to find the height of the cylinder. Plugging in the values, we get 6 = πr^2h. Since the radius of the cylinder is half the length of side AB, which is 3, we can solve for h to find that h = 4/π. Using the length of the arc, BC, and the radius of the cylinder, we can find the angle ABC using the formula θ = s/r, where θ is the angle in radians, s is the length of the arc, and r is the radius of the cylinder. Plugging in the values, we get θ = 6π/3 = 2π.

The number of fiction books is 500 and non fiction books is 1500.

Step-by-step explanation:

Given:

Total book library contains = 2000.

There are 3 times as many non fiction books as fiction books.

Now, to determine the number of non fiction books and fiction books.

Let the fiction books be [tex]x.[/tex]

And the non fiction books be [tex]3x.[/tex]

Total books = 2000.

Now, to get the number of non fiction books and fiction books we put an equation:

[tex]3x+x=2000.[/tex]

[tex]4x=2000.[/tex]

Dividing both sides by 4 we get:

[tex]x=500.[/tex]

Fiction books = 500.

Non fiction books = [tex]3x=3\times 500=1500.[/tex]

Therefore, the number of fiction books is 500 and non fiction books is 1500.

To solve for the number of nonfiction and fiction books in the library, set up a system of equations and solve them to find there are 500 fiction books and 1500 nonfiction books.

To determine the number of nonfiction and fiction books in the library, we can use a system of equations. Let's denote the number of fiction books as F and the number of nonfiction books as NF. According to the problem, the total number of books in the library is 2000, and there are 3 times as many nonfiction books as there are fiction books.

Our two equations will be:

F + NF = 2000 (Total number of books)

NF = 3F (3 times as many nonfiction books)

To solve these equations:

Substitute the second equation into the first one:

F + 3F = 2000

4F = 2000

Divide both sides by 4 to find F:

F = 2000 / 4

F = 500

There are 500 fiction books. Now we can find the number of nonfiction books by multiplying 500 by 3:

NF = 3 * 500 = 1500

So, the library has 500 fiction books and 1500 nonfiction books.

Answer:

Finance Charge = $1.42

New Account Balance = $90.02

Step-by-step explanation:

APR (Annual Percentage Rate) = 22%

Periodic Rate = 1.83% (APR/12)

Beginning Balance = $102.33

Payment made on 15th day = $25.00

Purchase made on 25th day = $11.27

Finance Charge = (Beginning Balance - Payment made on 15th day) x Periodic Rate

Finance Charge = ($102.33 - $25.00) x 0.0183

Finance Charge = $77.33 x 0.0183

Finance Charge = $1.42

New Account Balance = Beginning Balance - Payment made on 15th day + Purchase made on 25th day + Finance Charge

New Account Balance = $102.33 - $25.00 + $11.27 + $1.42

New Account Balance = $90.02

The finance charge is approximately $1.67, and the new account balance after accounting for the payment and purchase is $90.27.

We start with the account balance on April 1st, which is $102.33. On April 15th, a payment of $25.00 is made, and on April 25th, a purchase of $11.27 is made.

1: Calculate the Average Daily Balance

Average Daily Balance = ( (14 * 102.33) + (10 * 77.33) + (6 * 88.60) ) / 30 = $91.22

2: Calculate the Finance Charge

Given the annual interest rate of 22%, we first find the monthly rate: 22% / 12 = 1.833%.

Then we calculate the finance charge:

Finance Charge = Average Daily Balance * Monthly Rate
Finance Charge = $91.22 * 0.01833 ≈ $1.67

3: Calculate New Account Balance

New Balance = Previous Balance - Payment + Purchase + Finance Charge

New Balance = $102.33 - $25.00 + $11.27 + $1.67 = $90.27

The new account balance is $90.27.

Step-by-step explanation:Women have two chromosomes XX and men have two also XY.

From the question, it can be seen that colorblindness is an X-linked recessive condition.

Let the X-linked recessive gene be specified as [tex]X^{-}[/tex] and the dominant gene which is not colorblind linked as [tex]X^{+}[/tex].

The question says the woman has a father who is colourblind which means her father possesses the X-linked recessive gene [tex]X^{-}[/tex] which means he has chromosomes [tex]X^{-}Y[/tex] and therefore must have given his daughter the recessive gene

For her husband who has normal vision his chromosomes will be [tex]X^{+} Y[/tex].

So, the probability that their son will be colourblind will be;

b/a=-25/7

from (1)

5-25/7+2 c/a=0

2 c/a+10/7=0

Answer:

46 jumps

Step-by-step explanation:

Since the grasshopper is two inches long, and can jump a distance of 40 inches, then its jump ratio is 2:40 = 1:20.

The athlete's body-length is 5 feet 9 inches. We convert this to inches which is 5 × 12 = 60 inches. We then add the remaining 9 inches to make it 60 + 9 = 69 inches. Since our jump ratio for the grasshopper equals that for the athlete, 1:20 = 69: 20 × 69= 69 : 1380. Thus the athlete's jump ratio is 69 inches to 1380 inches.

The athlete wants to cover one mile and we know that 1 mile = 63360 inches. So, we divide the distance the athlete wants to cover(1 mile = 63360 inches) by his jump-length(1380 inches) to get the number of jumps it takes to cover a mile. Number of jumps × jump-length of athlete = one mile, so Number of jumps = one mile/jump-length of athlete = 63360 inches/ 1380 inches= 45.9 jumps ≈ 46 jumps.

It would take the athlete approximately 46 jumps to cover one mile.

To solve this problem, we'll start by establishing the jumping ratio of the grasshopper and then applying that ratio to the athlete to determine how many jumps it would take for the athlete to cover one mile.

First, let's calculate the jump ratio for the grasshopper:

- Grasshopper's length: 2 inches

- Grasshopper's jump length: 40 inches

The ratio of the grasshopper's jump length to its body length is:

[tex]\[ \text{Jump ratio} = \frac{40 \text{ inches}}{2 \text{ inches}} = 20 \][/tex]

Next, let's find the athlete's height in inches:

- Athlete's height: 5 feet 9 inches

- 1 foot = 12 inches

Thus, the athlete's height in inches is:

[tex]\[ 5 \text{ feet} \times 12 \text{ inches/foot} + 9 \text{ inches} = 60 \text{ inches} + 9 \text{ inches} = 69 \text{ inches} \][/tex]

Using the grasshopper's jump ratio, we can determine the distance the athlete could jump:

[tex]\[ \text{Athlete's jump length} = 69 \text{ inches} \times 20 = 1380 \text{ inches} \][/tex]

Now, we need to determine the total number of jumps the athlete would need to cover one mile. First, convert one mile to inches:

- 1 mile = 5280 feet

- 1 foot = 12 inches

Therefore, the distance of one mile in inches is:

[tex]\[ 5280 \text{ feet} \times 12 \text{ inches/foot} = 63360 \text{ inches} \][/tex]

Finally, the number of jumps required for the athlete to cover this distance is:

[tex]\[ \text{Number of jumps} = \frac{63360 \text{ inches}}{1380 \text{ inches/jump}} \][/tex]

Calculating this value:

[tex]\[ \text{Number of jumps} \approx \frac{63360}{1380} \approx 45.92 \][/tex]

Since the number of jumps must be a whole number, we round 45.92 to the nearest whole number:

[tex]\[ \text{Number of jumps} \approx 46 \][/tex]

Therefore, it would take the athlete approximately 46 jumps to cover one mile.

He used a coupon for 1/2 off the price of the bat which is $69. With the coupon applied, the cost of the bat would be 69 × 1/2 = $34.5

He also used a coupon for 1/2 off the price of the glove which is $75. With the coupon applied, the cost of the bat would be 75 × 1/2 = $37.5

Therefore, a numerical expression to find the total cost of the bat, the glove, and 3 baseballs which are 5.50 each would be

34.5 + 37.5 + 3 × 5.5 = $88.5

The total cost of the bat, the glove, and the baseballs is $88.5 and this can be determined by using the given data and arithmetic operations.

Given :

He used a coupon for 1/2 off the price of the bat which is $69 and the glove which is $75.

The following steps can be used to evaluate the total cost:

Answer:

A. Stereo Store Job is highest paying Job.

B. The Difference between the weekly salaries of these two jobs is $45.

Step-by-step explanation:

Given:

Annual Pay of job in stereo store =  34.6K

Now K here means (1000).

So we can say that;

Annual Pay of job in stereo store = [tex]\$34.6\times 1000= \$34600[/tex]

Also Given:

Weekly salary of Job at clothing store = $620

We need to find which job is the higher-paying job.

Also We need to find the difference in the weekly salaries of these two jobs

Solution:

First we will find the weekly salary of  job in stereo store.

Now we know that there are 52 weeks in a year.

So weekly salary of  job in stereo store can be calculated by Annual Pay of job in stereo store divided by total number of weeks.

framing in equation form we get;

weekly salary of  job in stereo store = [tex]\frac{34600}{52}=\$665.38[/tex]

Now we see that weekly salary of  job in stereo store is greater than Weekly salary of Job at clothing store.

Hence Stereo Store Job is highest paying Job.

Now we need to find the  difference in the weekly salaries of these two jobs.

difference in the weekly salaries can be calculated by weekly salary of  job in stereo store minus weekly salary of  job in clothing store.

framing in equation form we get;

Difference = [tex]\$665.38-\$620 =\$45.38[/tex]

Rounding to nearest dollar we get;

Difference = $45

Hence the Difference between the weekly salaries of these two jobs is $45.

A. The job in the clothing store is the higher-paying job. B. The difference in the weekly salaries of these two jobs is $45.

To determine which job is higher-paying, we need to compare the annual salaries of both jobs and convert them to weekly salaries for a fair comparison, assuming a standard work year of 52 weeks.

A. Comparing the annual salaries:

1. The job at the stereo store pays $34,600 per year. To find the weekly salary, we divide this amount by 52 weeks:

[tex]\[ \frac{34,600}{52} = 665.38 \][/tex]

So, the weekly salary for the job at the stereo store is approximately $665.38.

2. The job at the clothing store pays a weekly salary of $620.

Now, comparing the weekly salaries:

Stereo store: $665.38 per week

Clothing store: $620 per week

The job at the clothing store pays more per week than the job at the stereo store.

B. Calculating the difference in weekly salaries:

To find the difference between the weekly salaries of the two jobs, we subtract the weekly salary of the stereo store job from the weekly salary of the clothing store job:

[tex]\[ 665.38 - 620 = 45.38 \][/tex]

Rounding to the nearest dollar, the difference in the weekly salaries is approximately $45.

However, the question asks for the difference in the weekly salaries of these two jobs, not the difference in the weekly salary of the stereo store job from the clothing store job. Since the clothing store job pays more, we should actually subtract the weekly salary of the clothing store job from the weekly salary of the stereo store job to find the additional amount the clothing store job pays per week:

[tex]\[ 620 - 665.38 = -45.38 \][/tex]

Since we are looking for a positive difference, we take the absolute value:

[tex]\[ |-45.38| = 45.38 \][/tex]

Rounding to the nearest dollar, the difference in the weekly salaries of these two jobs is approximately $45. However, it seems there was a mistake in the initial answer provided for part B. Let's correct this:

The correct calculation for the difference in weekly salaries is:

[tex]\[ 665.38 - 620 = 45.38 \][/tex]

Rounding to the nearest dollar, the difference is $45.

The value of missing coordinate "r" is -4

Solution:

Given that,

The points (1, r) and (4, -13) lie on a line with slope – 3

To find: missing coordinate r

Step-by-step explanation:

The bonds are being sold at 110.611% of their face value, so each bond costs roughly $1,106.11. Therefore, to purchase three bonds, Sean would need to pay roughly $3,318.33.

When the question states that the bonds are 'selling at 110.611', it means that each bond is sold at 110.611% of its face value, which is $1,000.
