Answer 16 cubic cm (cm^3)
Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube
Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm

Answer:
32.5 ft
Step-by-step explanation:
The length of the side opposite the given angle is found using the sine relation:
Sin = Opposite/Hypotenuse
height on building = (33 ft)·sin(80°) ≈ 32.5 ft
The ladder reaches about 32.5 feet up the side of the building.
_____
<em>Additional comment</em>
The maximum angle compliant with OSHA safety rules is 75.5°.
Answer:
$20.833
Step-by-step explanation:
HEB:
Total cost = 2.50m
Costco:
Total cost = 50 + 1.75m
Where,
m = number of mangoes
HEB = Costco
2.50m = 50 + 1.75m
2.50m - 1.75m = 50
O.75m = 50
m = 50 / 0.75
= $20.833
Let's call airplanes "a" and helicopters "h".
The total number of models is 35. This means that a+h=35
4 times as many model airplanes as model helicopters. This means a=4h.
we can substitute this into the previous equation:
4h+h=35
5h=35
dividing by 5:
h=7
so he has 7 helicopters and 4*7=28 airplanes
