Find the length of AB

Answers

Answer:

17 units

Step-by-step explanation:

You can find the lenght of drawing a triangle and counting the x units and y units, thereby the AB would be the hypotenuse.

X units ( base ) = 15 units

Y units ( height ) = 8 units

AB = root of 8^2 + 15^2

AB = root of 289

AB = 17 units

Mr. Stein receives a water bill from city hall. He notices that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used. Mr. Stein wants to construct a model describing the relationship between the cost of his water bill and the amount of water he uses. Which statement best describes the model that Mr. Stein should create?

Answers

Complete question is;

Mr. Stein receives a water bill from city hall. He notices that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used. Mr. Stein wants to construct a model describing the relationship between the cost of his water bill and the amount of water he uses.

Which statement best describes the model that Mr. Stein should create?

A. Mr. Stein should use a linear model, since the water bill changes at a constant rate relative to the amount

of water he uses.

B. Mr. Stein should use an exponential model, since the water bill changes at a constant rate relative to the amount of water he uses.

C. Mr. Stein should use a linear model, since the water bill changes at a constant percent rate relative to the amount of water he uses.

D. Mr. Stein should use an exponential model, since the water bill changes at a constant percent rate relative to the amount of water he uses.

Answer:

Option A: Mr. Stein should use a linear model, since the water bill changes at a constant rate relative to the amount

of water he uses.

Step-by-step explanation:

We are told that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used.

Since there's a fixed charge of $50 for fire and sewer service and also that the city charges $3 for every 1000 gallons of water used. It means that there is a constant rate of charge for every 1000 gallons used.

It means that the bill he gets depends on the rate of water he consumes.

Thus, stein should use a linear model because the water bill changes at a constant rate relative to the water he consumes.

Write an absolute value inequality for the recommended air pressure range for each type of ball. Use the variable x for the ball's actual air pressure. Soccerball 12.05 recommended psi tolerance+3.55 Basketball 8.00 average recommended psi tolerance +0.5 volleyball 4.44 average recommended psi tolerance +0.18

Answers

Answer:

For Soccer ball:

x = | 12. 05 + 3.55 |

For basketball:

x = | 8.00 + 0.5 |

For volleyball:

x = | 4.44 + 0.18 |

Step-by-step explanation:

Given the following :

Let x = ball's actual air pressure

_________avg Recommended psi ___tolerance

Soccer ball____ 12. 05 ____________+3.55

Basketball _____8. 00_____________+0.5

Volleyball _____ 4.44 _____________ + 0.18

Actual air pressure = | average recommended psi + tolerance |

Hence ;

For Soccer ball:

x = | 12. 05 + 3.55 |

For basketball:

x = | 8.00 + 0.5 |

For volleyball:

x = | 4.44 + 0.18 |

Cynthia, Annie, and Suz went to Pepe's pizza palace for dinner. They shared a large pizza and each girl ordered? A soda. When the bill came they talked about how to slit it up. Annie, you had 3 slices and a medium soda so you should pay one-third of the bill. I'll chip in a dollar more than that, replied Annie.And since you had only 2 slices and also ordered a small soda, you should pay 20% of the bill.Cynthia said I ate 3 slices and had a large soda so I'll pay the remaining $8.80. How much was the total bill for the pizza and th 3 sodas and how much did each girl pay.

Answers

Answer:

The total bill = $20.85

Annie = $7.95

Suz = $4.17

Cynthia = $8.80

Step-by-step explanation:

Let the total bill = $x

For Annie

Annie, you had 3 slices and a medium soda so you should pay one-third of the bill. I'll chip in a dollar more than that, replied Annie.

Annie = 1/3 of x + $1

= 0.33x + $1

For Suz

And since you had only 2 slices and also ordered a small soda, you should pay 20% of the bill.

20% of x = 1/5x

= 0.2x

Cynthia said I ate 3 slices and had a large soda so I'll pay the remaining $8.80.

0.33x + $1 + 0.2 x + $8.80 = $x

Collect like terms

$1 + $8.80 = x - 0.33x - 0.2x

$9.80 = x - 0.53x

$9.80 = 0.47x

x = $9.80/0.47

x = $20.85106383

≈ $20.85

Therefore,

For Annie,

The total amount she is paying is

0.33x + $1

= 0.33 × $20.85 + $1

= $6.95 + $1

= $7.96

For Suz

= 0.2x

= 0.2 × $20.85

= $4.17

For Cynthia

= $8.80

Last week John’s hamster drank 45 mL of water. This week he drank 25 mL of water. By what percent did the hamster’s intake of water decreased?

Answers

Answer:

Percentage decrease is 55%.

Step-by-step explanation:

Given the following data;

Original (old) number = 45mL

New number = 20mL

[tex] Percentage \; decrease = \frac{change\; in \;amount}{original\;number} * 100[/tex]

Change in amount = 45 - 20 = 25

Substituting into the equation, we have;

[tex] Percentage \; decrease = \frac{25}{45} * 100[/tex]

[tex] Percentage \; decrease = 0.55 * 100[/tex]

[tex] Percentage \; decrease = 55%[/tex]

Therefore, the hamster’s intake of water decreased by 55%.

A realtor sells 3 houses this month for a total of $825,000, and each buyer uses her company to process their loan.

She earns a base pay of $2,600 each month
plus 1.5% of her total house sales.

She also gets a fee of $12 for each loan she gets serviced through her company.

What are her total earnings for the month?

Enter the correct answer in the box.

Answers

Answer:

$2,651

Step-by-step explanation:

The first step is to find what 1.5% of $2,600 is.

Secondly, divide 2600 / 100 = 26

Finally, multiply 26 by 1.5 = 39.

Add 39 and 12 to 2600 = $2,651.00 total earnings for the month.

Answer:

15,011

Step-by-step explanation:

Because 1.5 percent of 825,000 is 12375. She gets 2,600, so add that, and 12 times 3 for 3 houses is 36.

Add 12,375+2,600+36, you get 15,011!

        6x = 5x - 8 + 17

        6x = 5x + 9     {Subtract 5x form both sides}

  6x - 5x = 9

a) x = 9

b) ∠FGH  = 5* 9 - 8
