6. 5 shirts  20 minutes Multiply both by 3 to get to 60 minutes 15 shirts  60 minutes 15 shirts per hour
7. 250 miles + 50 miles = 300 miles 300 miles / 5 hours = 60 miles per hour
8. 360 pages / 12 hours = 30 pages per hour400 pages / 30 pages per hour = 13 1/3 hours = 13 hours and 20 minutes

6) 20 minutes is 1/3 of an hour. To find out how many T-shirts per hour, we multiply how many can be produced in 20 minutes by 3.

5 T-shirts X 3 =
15 T-shirts per hour.

7) From Jefferson to Paxten overall, it's 300 miles. Since we're determining miles per hour, we divide 300 by 5 to find out how fast he was travelling.

300 / 5 = 60 MPH

8) This problem explains a fraction, we just have to find the corresponding fraction with a missing denominator.

360 / 12
400 / ?

360 / 400 = 9 / 10

Multiplying the reciprocal by 12 will give us the answer.

(10 / 9) X 12 = 13 Hours and 20 Minutes.

Hope this helps!

Heidi wants to make some biscuits using this recipe.

Andre45 [30]

The most cookies Heidy can make is 36 cookies.

<h3>How to calculate how many cookies can Heidy make?</h3>

To know how many cookies Heidy can make, you have to take into account the following information:

12 cookies need the following ingredients:

125g butter
200g flour
50g sugar

In the case in which Heidy has more ingredients, we must carry out the following operations:

Divide the quantities, in the reference quantity we have:

500g of butter ÷ 125g of butter = 4
700g flour ÷ 200g flour = 3.5
250g of sugar ÷ 50g of sugar = 5

According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.

So the number of cookies Heidy can make are:

12 × 3.5 = 42

HELP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

sasho [114]

Answer is 54^2.

since there are triangles in this one, it is easier to do this. all you have to do is make boxes in and since there are angles, outside the lines. like this picture.

the orange is 1
red and dotted is 2
blue is 3
purple is 4(a regular box which should be easy to count.

all you have to do is add up all the boxes within the boundaries.
boundary 1: 12
boundary 2: 18
boundary 3: 6
boundary 4: 36

now when the boundary has a triangle in it (1, 2, & 3) divide the number you got in half or 2.
boundary 1: 6
boundary 2: 9
boundary 3: 3

the ractangle box doesn't not get divided.
boundary 1: 6
boundary 2: 9
boundary 3: 3
boundary 4: 36

add all the numbers you got now for each boundary and that would be your area squared.

6+9+3+36=54^2

so your final answer is 54^2.

i hope this helps you.
