Step-by-step explanation:

The figure has 4 sides, so is a quadrilateral. Opposite sides are parallel, so the figure is a parallelogram.

Angles are not 90°, so the figure is not a rectangle. Sides are not all the same length, so the figure is not a rhombus. Because the figure has two pairs of parallel sides (not just one pair), it is not a trapezoid.

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;

Chromosomes [tex]X^{+}[/tex] Y

[tex]X^{+}[/tex] [tex]X^{+} X^{+}[/tex] [tex]X^{+}Y[/tex].

[tex]X^{-}[/tex] [tex]X^{-} X^{+}[/tex]. [tex]X^{-}Y[/tex].

Therefore, the probability that their son will be color blind = ¼ or 0.25 or 25%

Answer: C) 44 mph

Step-by-step explanation:

We know that [tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]

Given : A car drives 40 miles on local roads at 20 mph.

i.e. Time taken : [tex]t_1=\dfrac{40}{20}=2\ hour[/tex]

Also, it drives 180 miles on the highway at 60 mph.

i.e. Time taken : [tex]t_2=\dfrac{180}{60}=3\ hour[/tex]

We know that the formula for Average speed is given by :-

[tex]A.V.=\dfrac{\text{Total distance}}{\text{Total Time}}[/tex]

So the average speed of the entire trip will be :-

[tex]\dfrac{40+180}{t_1+t_2}\\\\\\=\dfrac{220}{2+3}=\dfrac{220}{5}\\\\=44[/tex]

Hence, the average speed of the entire trip is 44 mph.

Therefore , the correct answer is C) 44 mph.

Answer:

The answer to your question is height = 12 mm

Step-by-step explanation:

Data

l = w = 9 mm

V = 324 mm³

h = ?

Formula

V = [tex]\frac{Ab x h}{3}[/tex]

Solve for h

                       3V = Ab h

                       3V / Ab = h    or     h = 3V / Ab

Find the area of the base

Ab = l x w

     = 9 x 9

     = 81 mm²

Substitution

                       h = [tex]\frac{3(324)}{81}[/tex]

Simplification

                       h = [tex]\frac{972}{81}[/tex]

Answer:

2,400cm^2

Step-by-step explanation:

This is quite an interesting question.

Now, we know the frame measures 60 by 80. We also know that the thickness of the frame is 10cm in length. Hence from the side of the mirror to the other side of the frame is 10cm.

We have the 10cm on each side of the frame. Making a total of 40cm and 20cm each allowance on the length and breadth of the mirror. The length and breadth of the mirror is thus 40cm by 60cm.

The area of a rectangle is L * B

The area of the mirror is 40 * 60 = 2,400cm^2

The fact that the width of each side of the frame is 10 cm means that each side of the mirror is 20 cm smaller than the corresponding side of the frame. Therefore, the mirror measures 40 cm by 60 cm, with an area of 2400.

Step-by-step explanation:

We are given the following in the question:

Total calories in a bag of carrot and a container of hummus dip = 650

Rosarita's snack:

Some of the bag of carrots and some of the container of hummus.

Total calories in Rosarita's snack = 260

Let x represents the total number of calories in the bag of carrots and y represents the total number of calories in the container of hummus.

Then, we can write the following equation to represent total number of calories in both a bag of carrot and a container of hummus dip:

[tex]x + y = 650[/tex]

Step-by-step explanation:

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

The slope of a line is given by formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Where, "m" is the slope of line

Here in this sum,

m = -3

[tex](x_1, y_1) = (1, r)\\\\(x_2, y_2) = (4, -13)[/tex]

Substituting the values in formula,

[tex]-3 = \frac{-13-r}{4-1}\\\\-3=\frac{-13-r}{3}\\\\-9 = -13 - r\\\\r = -13+9\\\\r = -4[/tex]

Thus the value of missing coordinate "r" is -4

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.

Answer D.It will increase 8 times.

Step-by-step explanation:

Answer: It will increase 8 times

Step-by-step explanation:

Range simply means the smallest number subtracted from the biggest number. Initially, the scores were 70, 72 and 68 then making the range 68-72 = 4. Now a new score is added which is 100 and it is obviously the biggest number now. So we subtract 68 from 100 that is ; 100-68= 32. This new range is 8 times more than the former. That is, 32/4 = 8.

Answer:

0.4

Step-by-step explanation:

Equation is

x-(-3.8)=2(x-1.7)

solving for x,

x+3.8=2x-3.4

x=0.4

Final answer:

The value of x is found by setting up an equation based on the distances provided and considering two separate cases for the absolute value. After solving the equation, the positive value of x is determined to be 7.2.

Explanation:

To solve for the value of x in this problem, we need to set up an equation based on the information given about the distances on a number line. The distance between x and -3.8 is twice the distance between x and 1.7. This translates to the following equation:

|x - (-3.8)| = 2|x - 1.7|

We then solve this equation step-by-step:

Therefore, the value of x to the nearest tenth is 7.2.

The number of shoes Paisley own is 75.

Step-by-step explanation:

Given:

Paisley was organizing her shoe collection.

She counted 24 pairs of sandals.

This represents 32% of the total number of shoes she owns.

Now, to find the number of shoes Paisley own.

Let the number of shoes Paisley own be [tex]x.[/tex]

According to question:

32% of [tex]x[/tex] = 24.

[tex]\frac{32}{100} \times x=24[/tex]

[tex]0.32x=24[/tex]

Dividing both sides by 0.32 we get:

[tex]x=75.[/tex]

Therefore, the number of shoes Paisley own is 75.

Answer:

The total number of shoes Paisley owns = 75

Step-by-step explanation:

Given:

24 pairs of sandals represent 32% of the shoes Paisley owns.

To find the total number of shoes Paisley owns.

Solution:

Let the total number of pairs of shoes be = [tex]x[/tex]

Thus, number of sandals can be represented as:

⇒ 32% of [tex]x[/tex]

⇒ [tex]0.32\times x[/tex]

⇒ [tex]0.32x[/tex]

Number of sandals = 24

So, we can write the equation as:

⇒ [tex]0.32x=24[/tex]

Solving for [tex]x[/tex]

Dividing both sides by 0.32.

⇒  [tex]\frac{0.32x}{0.32}=\frac{24}{0.32}[/tex]

⇒ [tex]x=75[/tex]

Thus, the total number of shoes Paisley owns = 75

Caleb made $105 mowing lawns and walking dogs, charging the rates shown. If he mowed half as many lawns as dogs walked, how many lawns did he mow and how many dogs did he walk? $7.50 for walking dogs and $20 for mowing lawns

Answer:

Caleb mowed 3 lawns and walked 10 dogs.

Step-by-step explanation:

Let the number of dogs he walked be 'd'.

Let number of lawn he mowed be 'l'.

Given:

If he mowed half as many lawns as dogs walked

So we can say that;

[tex]l=\frac{1}{2}d=0.5d \ \ \ \ equation\ 1[/tex]

Now given:

Cost for mowing each lawn = $20

Cost for walking each dog = $7.50

Total amount made = $105

Now we can say that;

Total amount made is equal to Cost for mowing each lawn multiplied by number of lawn he mowed and Cost walking each dog multiplied by number of lawn he mowed.

framing in equation form we get;

[tex]20l+7.5d=105 \ \ \ \ \ equation \ 2[/tex]

Substituting equation 1 in equation 2 we get;

[tex]20(0.5d)+7.5d=105[/tex]

Applying distributive property we get;

[tex]10d+7.5d=105\\\\17.5d=105[/tex]

Dividing both side by 17.5 we get;

[tex]\frac{17.5d}{17.5}=\frac{105}{17.5}\\\\d= 6[/tex]

Substituting the value of 'd' in equation 1 we get;

[tex]l=0.5d=0.5\times6=3[/tex]

Hence Caleb mowed 3 lawns and walked 10 dogs.

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.

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.

let the eq. of circle be a(x²+y²)+bx+cy+d=0

x²+y²+b/a x+c/a y+d/a=0

if it passes through (0,0)

0²+0²+b/a*0+c/a*0+d/a=0

so d=0

Hence x²+y²+b/a x+c/a y=0

if it passes through (1,2) and (3,-1)

1²+2²+b/a×1+c/a×2=0

5+b/a+2c/a=0   ...(1)
