After 10 weeks, how much money would William have in his bank account?

A.$165

B.$170

C.$200

D.$314

Answers

Answer:

if he earned $20 a weak after ten weeks it would be $200

Option A is correct,  $165 is the account balance of Willian after 10 weeks.

What is a function?

A relation is a function if it has only One y-value for each x-value.

Given that William bank account is modeled by the function f(x)=12x+45

f(x) equal to twelve times of x plus forty five.

Where x represents the number of weeks and f(x) represents the total balance.

45 represents the initial amount.

x represents the number of weeks.

We have to find the account balance after 10 weeks.

Plug in x as 10 to find the amount after 10 weeks.

f(x)=12(10)+45

When twelve is multiplied with ten we get 120,

=120+45

Add 120 and 45 we get

=165

Hence, $165 is the account balance of Willian after 10 weeks.

A Rube Goldberg machine consists of a series of devices that perform a simple task. Kate is drawing a scale model of her Rube Goldberg machine, which she plans to build and enter into a contest. A bicycle wheel on the scale model is 2 inches in diameter, while in the actual machine, it will be 28 inches in diameter.

Question 1
Part A

Based on the measures of the wheel diameter, what is the unit rate of inches of machine per inch of the model?

Answers

Answer:

The unit rate is 16

Step-by-step explanation:

The unit rate of the machine is given as 14 inches per model.

What is Unitary method?

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The diameter of bicycle wheel on the scale model is 2 inch.

And, the diameter in actual machine is 28 inch.

The unit rate of the machine can be found by using unitary method as follows,

For 2 inch diameter on scale model, diameter in machine = 28 inch

For 1 inch diameter on scale model, diameter in machine = 28/2 inch

                                                                                                = 14 inch.

Hence, the unit rate of inches of machine per inch of the model is 14 inches per model.

In 2 hours they rest for 16 minutes.

So first we should work out how long they rested for in 1 hour.

We do this by simply doing 16 (minutes of rest) divided by 2 (hours of dancing):

16 / 2 = 8

In one hour of dancing they rest for 8 minutes.

Now to work out how long they rested in 3 hours, we simply do 3 (hours of dancing) x 8 (minutes of rest per hour):

3 x 8 = 24

The couple spent 24 minutes resting in 3 hours of dancing.

Answer:

The couple rested for 24 mins in 1 hour

Step-by-step explanation:

The unit rate is 8

What does the excerpt reveal about the narrators conflict?answer choices:He is absorbed within himself.He is avoiding paying his rent.He is angry about his poverty.He is uncertain about his health.This is the text:On an exceptionally hot evening early in July a young man came out of the garret in which he lodged in S. Place and walked slowly, as though in hesitation, towards K. bridge. He had successfully avoided meeting his landlady on the staircase. His garret was under the roof of a high, five-storied house and was more like a cupboard than a room. The landlady who provided him with garret, dinners, and attendance, lived on the floor below, and every time he went out he was obliged to pass her kitchen, the door of which invariably stood open. And each time he passed, the young man had a sick, frightened feeling, which made him scowl and feel ashamed. He was hopelessly in debt to his landlady, and was afraid of meeting her. This was not because he was cowardly and abject, quite the contrary; but for some time past he had been in an overstrained irritable condition, verging on hypochondria. He had become so completely absorbed in himself, and isolated from his fellows that he dreaded meeting, not only his landlady, but anyone at all. He was crushed by poverty, but the anxieties of his position had of late ceased to weigh upon him. He had given up attending to matters of practical importance; he had lost all desire to do so. Nothing that any landlady could do had a real terror for him. But to be stopped on the stairs, to be forced to listen to her trivial, irrelevant gossip, to pestering demands for payment, threats and complaints, and to rack his brains for excuses, to prevaricate, to lieno, rather than that, he would creep down the stairs like a cat and slip out unseen.
