Helen determined she walks about 1,800 steps per 4/5 mile. How many steps did she take if she walked 3 miles?

Answers

Answer 1

Answer: $1,800\ steps\ \ \rightarrow\ \ (4)/(5) \ mile\n x\ \ \rightarrow\ \ 3\ miles\n \n(4)/(5) \cdot x=1,800\cdot 3\ /\cdot(5)/(4) \n \nx=1,800\cdot(5)/(4)\cdot3 \n \nx=450\cdot15\n \nx=6750\ [steps]$

Answer 2

Answer: I think the answer is 6750 steps

What is the mixed number for 4.8

Answers

it is 4 $(8)/(10) or (4)/(5)$

4.8 in a mixed number is 4 4/5 because 4.8 in a fraction is 48/10, simplified 24/5. Then you divide 24 by 5 and it will give you 4 4/5!

Create a equation using this graph?

Answers

The formula for a straight line is y=mx+b, where m is the slope and b is the y-intercept.

To find out the slope, we use a formula known as rise/run.

Rise means how high a point goes between any two points and run is how far the space is between any two points.

We can see that there are two points give to us. Now we ask our self how high do we have to go to reach the second points’ height. If we count it we go five UP. Meaning that the rise is positive 5.
Now we see how far the two points are. If we count it, we go 1 space the LEFT meaning -1 since going left on a graph means x is getting smaller.

Now that we have he two values, we put them into rise/run

5/-1=-5

So our value of m is -5
Meaning y=-5x+b

We still have our value of b to find and we can do this by choosing any one point on the graph and substituting it into the equation. We know that one of our points is (3,0)

We put these into the equation

y=-5x+b
0=-15+b
b=15

Therefore, y=-5x+15

What is 32.7 times 10

Answers

The answer is 327. Remember that when you multiply a number by ten, you move the decimal point to the right one place.
Hope that helped you.

32.7x10 would be 327
because since your multiplying a decimal by ten all you have to do is move the decimal over 1
So your answer is 327

Hope this helped! :))

The ratio of girls to boys in the grade is 9 to 11. If there are 135 girls, how many boys are there?

Answers

There would be 165 boys in the grade.

I got this because I did 135/9. I got 15. Then I multiplied 11*15.

There is 165 boys. Multiply both sides by 15 to get an equal ratio

403010Pa2 4 8 10Number of ticketsThe graph shows the cost of buying raffle tickets.19. write an equation shows the cost y in terms of the number of tickets x?Equation:

Answers

Simple..

you have y which is the cost of the tickets..and you have x which is the number of tickets..

So, you have those points on the graph....find an equation!

Take any of those coordinates..and find the equation of the line...in the form of y=mx+b

(2,10) and (5,25)

Using: $( y_(1)- y_(2) )/( x_(1)- x_(2) )$

$(10-25)/(2-5) = (-15)/(-3) =5$

Thus, you know your slope. m=5

But, remember it's in the form of y=mx+b

So, use any of the coordinates...let's use (2,10)

10=5(2)+b

10=10+b

0=b

Thus, your equation is... y=5x

Thus, your answer.
