Answer:

$2640

Step-by-step explanation:

Sheila's car payment is 9% of her total income.

let i = total income

this equation can be used to represent the information :

9%  x i = $297

to determine i, divide both sides of the equation by 9%

$297 / 0.09 = $3300

After the marriage, the car payment which is 3300 would be 5% of the combined income.

let c = combined income

5% x c = $297

c = $297 / 0.05 = $5940

Ryan's income = combined income - Sheila's income

$5940 - $3300 = $2640

Answer:

1187.52 yd^2

Step-by-step explanation:

SA=2πrh+2πr^2

R=9

H=12

So, 2(3.14)(9)(12)+2(3.14)(9)(9)=1187.57yd^2

Answer:

b; 1 real root and 2 imaginary roots

Step-by-step explanation:

From here, we have

x(x^2 + 121) = 0

x = 0 (1 real root)

or

x^2 + 121 = 0

x^2 = -121

x = √(-121) (2 imaginary roots)

so is would be two complex numbers from above

Answer:

wel swam 86 meters. Tyrel swam 53 meters. so what is the question

Answer:

Im guessing its who swam faster.

Answer:

yes

Step-by-step explanation:

10 is half of 20 but the equation is 11/20 therefore 11/20 is greater than 10/20=1/2

[tex]( - 6 + 2y)[/tex]

answer the question

Given:

Number of students who has a cat and a dog = 5

Number of students who has a cat but do not have a dog = 11

Number of students who has a dog but do not have a cat = 3

Number of students who neither have a cat nor a dog = 2

To find:

The probability that a student has a cat given that they do not have a dog.

Solution:

Let the following events:

A = Student has a cat

B = Do not have a dog

Total number of outcomes is:

[tex]5+3+11+2=21[/tex]

The probability that a student has a cat but do not have a dog is:

[tex]P(A\cap B)=\dfrac{11}{21}[/tex]

The probability that a student do not have a dog is:

[tex]P(B)=\dfrac{11+2}{21}[/tex]

[tex]P(B)=\dfrac{13}{21}[/tex]

The conditional probability is:

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{\dfrac{11}{21}}{\dfrac{13}{21}}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{11}{13}[/tex]

Therefore, the probability that a student has a cat given that they do not have a dog is [tex]\dfrac{11}{13}[/tex].

Answer:

the answer is the question with $580 in it please correct me if im wrong

Step-by-step explanation:

Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:

50% chance of $1,000 gain: 0.5 x $1,000 = $500

35% chance of $200 gain: 0.35 x $200 = $70

15% chance of $600 loss: 0.15 x -$600 = -$90

Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.

The expected return on FLMD is calculated in the same way:

80% chance of $750 gain: 0.8 x $750 = $600

20% chance of $100 loss: 0.2 x -$100 = -$20

Therefore, the expected return on FLMD is $600 - $20 = $580.

Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.

The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

If you roll a numbered cube once, your chance of getting a 4 is 1/6. If you roll twice, your chance of getting a 4 is 2/12. If you roll three times, your chance of getting a 4 is 3/18. You see the pattern here? Try it yourself and see if you can get it! If you can't understand it, let me know and I'll give you the answer!

Biased, because some students may not like that color, and thus going off of the most popular opinion is only supporting the most popular color. Adding onto that, not every student even gets to vote since it is only every 4th student.

Answer:

a = 9.4 cm

b = 12.0 cm

Step-by-step explanation:

Check the image uploaded for diagram;

For the first diagram, side length a is calculated as follows;

a² = 8²  +  5²

a² = 64  +  25

a² = 89

a = √89

a = 9.4 cm ( approximated to 1 decimal place)

For the second diagram, side length b is calculated as follows;

b² = 17²  -  12²

b² = 145

b = √145

b = 12.0 cm (approximated to 1 decimal place)

Answer:

95/9

Step-by-step explanation:

It will be easier for us to make the mixed numbers fractions.

2 1/3 = 7/3

8 2/9 = 74/9

now we want them to have the same denominator so we multiply the 7/3 fraction by 3/3.

21/9 + 74/9 = 95/9

Step-by-step explanation:

Answer:

Step-by-step explanation:

The function for this problem is: h(t) = -16(t)^2 + vt + s h= the height t= time v= velocity s= starting height With the information given, we know that the starting height is 0, since it was from the ground, and the velocity of the ball is 35 feet per second. Inserting the these information into the equation, we get: h(t) = -16(t)^2 + 35t Now the question asks to find the maximum height. It can be done by using a grapher to graph the maximum of the parabola. It could also be done by finding the vertex, which would be the maximum, of the graph by using x= -b/(2a), where b is equal to 35 and a is equal to -16. We get x=35/32, the x-value of where the vertex lies. You can use this value as the t-value in the previous equation to find the h-value of the vertex. When you do, you get h= 19.1 feet, or answer D.

Answer:

x = 45

Step-by-step explanation:

The angles are supplementary

(2x + 40) + (3x - 85) = 180

Combine like terms

5x - 45 = 180

Add 45 to both sides

5x = 225

Divide both sides by 5

x = 45

Answer: -7

Step-by-step explanation:

From the information given, we are.l told that Oscar's elevation change after 12 minutes was -84 feet.

Since his elevation was changing at a constant rate, his elevation change per minute will be:

= -84 feet / 12

= -7feet/minutes

Therefore, the integer is -7.
