Corrine has 9.6 pounds of trail mix to divide into 12 bags .How many pounds of trail mix will go in each bag?

Answers

Corrine has 9.6 pounds of trail mix to divide into 12 bags then the total amount of trail mix in each bag is 0.8 pounds and this will be determined by using the arithmetic operations.

Given :

  • Corrine has 9.6 pounds of trail mix.
  • Total number of bags = 12.

The following steps can be used to determine the amount of trail mix in eachbag:

Step 1 - Divide 9.6 by 12 that is, the total amount of trail mix by the total number of bags.

=(9.6)/(12)

Step 2 - Simplify the above expression.

=0.8

Corrine has 9.6 pounds of trail mix to divide into 12 bags then the total amount of trail mix in each bag is 0.8 pounds.

Describe and correct the error in finding the product
2/5×3/10=6/50=3/25

Answers

Answer: There is not error in finding the product. The result is: =(3)/(25)


Step-by-step explanation:

1. You have the following multiplication shown in the problem above:

(2)/(5)*(3)/(10)

2. To solve it you must multiply the numerators and multiply the denominators, as you can see below:

(2*3)/(5*10)=(6)/(50)

3. When you simplify the product, you obtain the following result:

=(3)/(25)

Using the line of best fit, estimate how may miles Jack ran the 10th week; show work.During which week would you expect Jack to run a full marathon, 26.3 miles? Do you think that you should round up or down to the nearest week? Why?

Answers

one way is to type it into your trusty TI and use the table from presing stat and then stat againg then calc then 4
so the equation that I got from your set of points is y=1.983333333333333x+0.80555555555
Take two points and find the slope. 
(4,9) (6,13)
y2-y1/x2-x1
4/2=2=m
y=2x+b
9=8+1
b+1
y=2x+1
Set x to 10 to find the 10th week
y=20+1
21 miles
Set y=26.3 to find which week.
26.3=2x+1
2x=25.3
x=12.6 weeks or round to 13 weeks
I think he should round up because in more slopes in between points, there is a lesser slope than 2.
Hope this helps.

The answer is about 27oz. and this is how you answer it.
pi(d/2)^2 * h = V
3.14(3.6in./2)^2 * 5.9in. =
3.14(1.8in.)^2 * 5.9in.   =
3.14 * 3.24 * 5.9in. ~
10.17in. * 5.9in. ~ 60in.^2
and 1in.^2 = 0.45oz. so
60 * 0.45oz. = 27oz.
that is with rounding to the nearest hundredth.
It's asking for volume, so it would be pi x r^2 x h
So it would be the volume (60.02424) divided by .45 which is 133 (rounded)
