Answer:
The answer is:
The paint will overfill the tray by 10.53 in3 (cubic inches).
Step-by-step explanation:
In order to determine the correct option, first we have to get the volume of the tray.
The volume of the tray is a solid prism, where its formula is:
width=10 in
length=14 in
deep=4 cm= in
Volume= cubic inches
The value of the deep measure was changed from cm to inches units.
We subtract the allowed volume of the gallon with the volume tray:
231-220.5=10.5 cubic inches
It means that 1 gallon of paint is enough to paint the tray, where the remaining paint is 10.5 cubic inches.
Finally, the correct option is:
The paint will overfill the tray by 10.53 in3 (cubic inches).

Answer:
A. no
B. no
C. obtuse
Step-by-step explanation:
For side lengths to form a triangle, the sum of the shorter two must exceed the longest.
A. 5 + 8 = 13 . . . . a line segment, not a triangle
B. 7 + 12 < 26 . . . . no closure, not a triangle
C. 11 + 15 > 20 . . . . a triangle. A picture shows it to be obtuse
You can also compare 11² +15² vs 20² ⇒ 346 vs 400. The long side is too long for a right triangle, so the triangle must be obtuse. (The Pythagorean theorem tells you a right triangle with those legs would have a long side of √346 = 18.6.)
