Answer:
The correct answer is B: 3 cubic feet.
Step-by-step explanation:
If you want to find the volume of a rectangular prism, you need to know the length, width, and height. The first rectangular prism is a cube with a length of 3 feet, so the volume of the figure would be
. The second rectangular prism has a length of 3 feet, a width of 2 feet, and a height of 4 feet, so the volume of the prism would be 3 × 2 × 4 =
. Now that you know the 2 volumes, you need to subtract the volumes in order to find the difference, which is 27 - 24 = 3
.
Answer:
h = 61.83 feet
Step-by-step explanation:
length of string from Hector to kite = c = 86 feet.
and 4 feet off the ground.
angle A = 42° 15' 30"
req'd: how high is the kite?
angle A = 42° + 15' (1° / 60') + 30"(1° / 3600'')
angle A = 42.26
to get the side a (height of kite) 4 feet above ground: use Sin(A) = opp / hyp
Sin(A) = a / c
Sin(42.26) = a / 86
a = Sin(42.26) * 86
a = 57.83 feet
therefore, the height of the kite from the ground = h = 57.83 + 4
h = 61.83 feet
Answer:
y = 1/5x
Step-by-step explanation:
Here, we have a direct relationship between the distance from lightning and the time it takes to hear thunder
Let the distance from lightning be y and the time it takes to hear thunder be x
If k is the proportionality constant, then;
y = kx
Now, let’s calculate k , given x 10 seconds and y = 2 miles
2 = 10k
k = 2/10 = 1/5
So the equation for the given situation is;
y = 1/5x
Whole number, real number, integer, and irrational.
