4 quarts in each gallon, so 8 quarts. There are 16 cups in each gallon, so 32 cups.
First we need to figure out the circumference of the gardening area. The circumference fell is the length around the circle. We can use the circumference formula:
2*pi*r or pi*d
Where r = radius and d=diameter
If you plug in the diameter of 18 ft you get:
18 * pi
= 56.55 ft
Since he can only buy whole foot amounts, we will round up to 57 ft, not down, because he can have a little extra, but can't be under the amount he needs.
Now if it cost $1.50 for every foot, we just multiply that by our footing
1.5 * 57 = $85.50
Answer:
The minimum amount of breaking strain the crane can handle is 6350 kg. (Since it is measured to 2 sig. figs, 6349 kg would round down to 6300 kg, hence the min. is 6350 kg.)
The maximum weight of each crate would be 94 kg. (Since it is measured to the nearest 10 kg, 95 kg would round up to 100 kg, hence the max. is 94 kg.)
Therefore, the greatest number of crates that can be safely lifted would be (6350/94) crates which is 67.5 crates, which rounded down is 67 crates.
All numbers are taken as integers in this answer.

Step-by-step explanation:
x = number of true/false questions
y = number of multiple choice questions
x + y = 40
2x + 3y = 144
from the first equation we get
x = -y + 40
this identity we can then use in the second equation
2(-y + 40) + 3y = 144
-2y + 80 + 3y = 144
y + 80 = 144
y = 64
and
x + 64 = 40
x = -24
that does not make any sense.
something is wrong with the problem description.
just think about it :
40 questions - if all of them would be multiple choice tests (creating the max. possible points for 40 questions), we could have only 40×3 = 120 points.
but the description says 144 points.
for 144 points we need at least 48 (144/3) questions.
that does not fit.
the described system does not have any natural number solution. therefore we are getting such crazy numbers as result, when we try.
