7 + 1.25m = 43.25
1.25m = 43.25 - 7
1.25m = 36.25
m = 36.25 / 1.25
m = 29....so Raymond was on the trampoline for 29 minutes
To find the volume of a box that would hold these nine cylinders, you would start with the formula for volume of a cylinder. V=pi x r^2 x h. Substitute in the known volume and the known Height. 9.425=pi x r^2 x 3. Divide both sides by three to get approximately 3.143 = pi x r^2. Divided by pi on both sides. This leaves you with one = r^2. So the radius is equal to one. If the radius equals one, the diameter is two. Assuming the cylinders are arranged in a 3 x 3 array, the length and width of the rectangle or box would be 6cm x 6cm. To find the volume of the box necessary, multiply the length of six by the width of six by the height of three. The volume would be 108 square cm.
Answer:
-18
Step-by-step explanation:
This is rather simple is it not?
To find the difference between the numbers, we simply have to subtract one from another. 
, which can be simplified into 
because subtracting a negative from a negative is simply done by adding the second negative as a positive to the first negative. Therfore = -18 which is your answer.
-18 is how much each number is subtracted to get the next.
Answer:
55
