The equation c= 0.25n can be used to find the cost (c) of buying n number of apples.

A) What is the constant of proportionality in this equation?
B) What information does the constant of proportionality provide us?
C) How many apples can you buy for $3?

Be sure to answer parts A, B and C. Make sure that you label each answer.

Answers

Answer:

(a) The constant of proportionality is 0.25

(b) 1 apple = $0.25

Step-by-step explanation:

Given

[tex]c= 0.25n[/tex]

Solving (a): The constant of proportionality;

For an equation:

[tex]c=kn[/tex]

Where

k = constant of proportionality

By comparing: [tex]c=kn[/tex] to [tex]c= 0.25n[/tex]

[tex]k = 0.25[/tex]

Hence, the constant of proportionality is 0.25

Solving (b): What information does [tex]k = 0.25[/tex] gives.

It represents the unit rate.

So, it means that 1 apple costs $0.25

Solving (c): Number of apples for $3.

This means that [tex]c = 3[/tex]

Substitute 3 for c in [tex]c= 0.25n[/tex]

[tex]3 = 0.25n[/tex]

Make n the subject

[tex]n = \frac{3}{0.25}[/tex]

[tex]n = 12[/tex]

sam writes on a white board the positive integers from 1 to 6 inclusive once each. she then writes p additional fives and q sevens on the board. The mean of all the numbers on the board is then 5.3. What is the smallest possible value of q?

Answers

Answer:7

Step-by-step explanation:

This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....

Also the 3 has a recurring symbol above it

The 7 is times seven so uh yeah<3

The smallest possible value of 'q' is 7 and this can be determined by using the hit and trial method and mean formula.

Given :

Sam writes on a whiteboard the positive integers from 1 to 6 inclusive once each. she then writes p additional fives and q sevens on the board.The mean of all the numbers on the board is then 5.3.

The following steps can be used in order to determine the smallest possible value of q:

Step 1 - The formula of the mean can be used in order to determine the smallest possible value of q.

Step 2 - The mean of all the numbers is given by:

[tex]\rm \dfrac{2+4+6+5+5p+7q}{6+p+q}=5.3[/tex]

[tex]\rm \dfrac{21 + 5p + 7 q}{6+p+q} = 5.3[/tex]

Step 3 - So, by the hit and trial method, the value of q can be determined.

Therefore, the value of 'q' is 7.

$59 power tool, 5% sales tax

Answers

Answer:

$2.95 sales tax. $61.95

Step-by-step explanation:

Answer:

$61.95

Step-by-step explanation:

First find the amount of sales tax.

59 times .05= 2.95

Sales tax is $2.95, because 5% is written as .05 as a decimal. .05 times 59 gives us how much money 5% of $59 is.

Now add that to the original price!

59+2.95= 61.95

So our final price is $61.95
