6 18
What is the constant of proportionality? Write your answer as a whole number or decimal.
The constant of proportionality(k) between a yard and a foot is 0.33.
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.
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.
OR
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.
:Done

What is the radius and diameter of the following circle? 4.2cm Please help
Answer:
The radius is 4.2 and the diameter is always twice the amount of the radius so its 8.4.
Step-by-step explanation:
Answer: R = 4.2cm and D = 8.4cm
Step-by-step explanation: The diameter of a circle is the full line across the circle. The radius of a circle is half of its diameter. The line shown go's halfway through the circle so its the radius. To find the diameter you multiply the radius by 2.

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.

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $550 on a credit card. If she makes no purchases or payments, she will go more and more into debt.
Which of the following sequences describes her increasing monthly balance?
A. 550.00, 649.00, 765.82, 903.67, 1,066.33, ...
B. 550.00, 559.90, 569.80, 579.70, 589.60, ...
C. 550.00, 559.35, 568.86, 578.53, 588.36, ...
D. 550.00, 559.90, 569.98, 580.24, 590.68, ...
E. 550.00, 550.99, 551.98, 552.98, 553.97, ...
Please also explain how (steps) to get the answer, thank you!
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.

Which of the following is the graph of the inverse of f(x)=2x-3
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 + 1.5The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.
