Pls Answer this using Algebraic expressions

Answers

Answer:

a) A total of 27 parents will receive a call on the third round of calls. b) A total of 39 parents would've been called by the end of the third round of calls. c) There would have to be a total of between 5 and 6 rounds

Step-by-step explanation:

Every time the total number of parents call 3 people, the number of parents tripled in every round.

3 to 9 to 27 to 51 to 153 to 459

Since 153 and 459 are between 5 and 6 rounds, the phone calls will stop between those 2 rounds.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

The variable feet and yards are in direct proportion.

Let,

yard = k(feet).

1 = 3k

k = 1/3 = 0.33.

Dan charges a fixed amount per hour. He charges £180 for a job which takes 12 hours. Work how much he will charges for a job which will take 18 hours.

Answers

Answer:

270 pounds

Step-by-step explanation:

half of 12 is 6, so 18. Then you take half of 180 and add to 180

Answer:

18 hours = £270

Step-by-step explanation:

Find how much he charges per hour. Divide:

[tex]\frac{180}{12}=15[/tex]

So ha charges about 15 an hour. Multiply this price by the number of hours:

[tex]15*18=270[/tex]

Therefore, he will charge £270 for a job that takes 18 hours.

Set a proportional relationship since he charges a fixed amount:

[tex]\frac{price}{time}=\frac{price}{time}[/tex]

Insert the appropriate corresponding values:

[tex]\frac{180}{12} =\frac{x}{18}[/tex]

Solve for the price after 18 hours of work, represented by x. Cross multiply:

[tex]12(x)=180(18)\\\\12x=3240[/tex]

Solve for x. Use inverse operations to isolate the variable. Divide both sides by 12:

[tex]\frac{12x}{12} =\frac{3240}{12} \\\\x=270[/tex]

Therefore, after 18 hours, he will charge £270.

Which of the following is the graph of the inverse of f(x)=2x-3

Answers

Answer:

(-3,0) (0,1.5

Step-by-step explanation:

The answer choice which is the graph of the inverse of f(x)=2x-3 is; the graph of; f(x) = x/2 + 1.5.

What is the graph of the inverse of f(x)=2x-3?

It follows from the task content that the function given is; f(x)=2x-3.

Hence, to find the inverse function;

y = 2x - 3x = y/2 + 1.5.

Interchange the variables;

y = x/2 + 1.5.

On this note, it follows that the inverse function is;

f(x) = x/2 + 1.5

The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.

Answers

Answer:

D. 550.00, 559.90, 569.98, 580.24, 590.68, ...

Step-by-step explanation:

So, her debt will increase of the interest rate of 1.8% on a credit card.

You have to multiply the rate by the amount that she owes. So, when you multiply 1.8% by $550 you get $9.90 amd you habe to add that to what she owes. You can't keep adding $9.90 because now her debt increased from $550 to $559.90. You now have to multiply $559.9 by 1.8% inorder to get her new amount of debt. If you multiply 1.8% by $550, then you are saying that she only has $550 as debt even though she now has $559.90 im debt. You must keep multiplying her new amount of debt by 1.8% to get her increasing monthly balance.
