For number 17 changed the 13 3/8 into a decimal to help you. 3/4 would be .75 and 13 3/8 would be 13.375
13.374 +.75 = 14 1/8 which would be 14. 125
14.125 + .75= 14 7/8 which would be 14. 875
so you can carry two more water bottles

The answer to number 17 is 2 water bottles. First you have to figure out how much pounds you have left to 15, thats when you subtract 15- 13 3/8= 1 5/8
Next, you subtract 3/4 from 1 5/8. You are left with 1/8 after subtracting 3/4 from 1 5/8 2 times. You are left with 1/8. You can not subtract 3/4 anymore, in this case if add another matter bottle, it will exceed the limit of 15 pounds. Hope this helped.

Answer:

1526.0 cubic units

Step-by-step explanation:

Rotating rectangle AKLM you will get cylinder with height KA and base radius KL. From the given data

$KA=\sqrt{(6-0)^2+(0-0)^2}=6,\\ \\KL=\sqrt{(0-0)^2+(9-0)^2}=9.$

The volume of the cylinder is

$V_{cylinder}=\pi r^2\cdot H.$

Then

$V_{cylinder}=\pi \cdot 9^2\cdot 6=486\pi \approx 1526.0\ un^3.$

Step-by-step explanation:

$\text{If is}\ \dfrac{3}{5}^4,\ \text{then}\ \dfrac{3}{5}^4=\dfrac{3\cdot3\cdot3\cdot3}{5}=\dfrac{81}{5}=16\dfrac{1}{5}\\\\\text{If is}\ \left(\dfrac{3}{5}\right)^4=\left(\dfrac{3}{5}\right)\left(\dfrac{3}{5}\right)\left(\dfrac{3}{5}\right)\left(\dfrac{3}{5}\right)=\dfrac{3\cdot3\cdot3\cdot3}{5\cdot5\cdot5\cdot5}=\dfrac{81}{625}$
