the scale of a map says that 6cm represents 15 km. what distance on the map represents an actual distance of 6 kilometres ​

Answers

Answer 1
Answer:

Answer:

2.4 cm

Step-by-step explanation:

(6)/(15) = (x)/(6) \n \n 15x = 6 * 6 \n \n 15x = 36 \n \n x = (36)/(15) \n \n x = 2.4

Wayne measured the width of a marker tip as 0.012 cm. What is the margin of error?A. 0.011 to 0.013

B. 0.007 to 0.017

C. 0.0125 to 0.0135

D. 0.0115 to 0.0125

Answers

Answer:

D. 0.0115 to 0.0125

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Before we can find an answer for this question we should know what a margin of error is.

Margin of Error is the minimum amount of error allowed in a specific measurement. This exists because of the miscalculations that can happen.

Knowing the information above we can confidently say that the answer is D. 0.0115 to 0.0125 .  This gives us a padding of error of 0.0005 over and under the actual value of 0.012.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
I think it's probably D. 0.0115 to 0.0125

Mt. Everest is 29,028 feet high. How many miles in this? (there are 5,280 feet in one mile) Solve.

Answers

That would be about 5.49 miles.


From 29,028 feet, divide that by 5,280 feet. This number gives you the amount of miles, which is roughly 5.49.

The graph shows the functions f(x), p(x), and g(x):Part A: What is the solution to the pair of equations represented by p(x) and f(x)?

Part B: Write any two solutions for f(x).

Part C: What is the solution to the equation p(x) = g(x)? Justify your answer.

Answers

The function f(x) is:

f(x)=x

This is because the line f(x) passes through the points (-1,-1), (0,0), (1,1) etc.

The function p(x) is:

p(x)=mx+C

Whereby (m) is the slope and (C) is a constant.

m=-4/3, as m=tan(ω)=O/A=-4/3 as slope is negative.

Now when y=-3, x=-3.

So:

-3=-4/3 *(-3) +C

-3= 4 + C

C=-7

This means that:

p(x)=-4/3x -7

Now, where p(x)=g(x), x=-6.

p(-6)=-4/3 * (-6) -7

p(-6)=24/3 -7

p(-6)=8-7

p(-6)=1

Therefore:

p(x) and g(x) meet at (-6, 1) and the solution to p(x)=g(x) is x=-6.

Oliver listens to 16 minutes of an audiobook every day during his commute to work. Let d represent the number of days commuting to work and m represent the total number of minutes Oliver listens to the audiobook while commuting.

Answers

We know that Oliver listens to 16 minutes of the audiobook every day during his commute to work. So, the equation would be m = 16d.
