Answer:
C. 262 cm
Step-by-step explanation:
Use the formula for the volume of a sphere, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
Since the diameter is 10 cm, the radius will be 5 cm
Plug in the radius into the formula:
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](5³)
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](125)
V = 523.6
Since the bowl is a hemisphere, divide this by 2:
523.6/2
= 261.8
Rounding to the nearest cm, the volume of the bowl is 262 cubic cm.
So, the correct answer is C. 262 cm
Consider the following figure.
Answer:
BD = 16
Step-by-step explanation:
By applying mean proportional theorem in the given right triangles,
[tex]\frac{AD}{BD}=\frac{BD}{CD}[/tex]
AD × CD = BD²
8 × 32 = BD²
BD = √256
BD = 16
Therefore, measure of side BD = 16 units.
A dolphin is swimming at a depth of –3.4 meters with respect to sea level when it begins diving deeper at a constant rate of –0.25 meter per second. In how many seconds will the dolphin reach a depth of 9.9 meters below sea level?
Answer: 26 s
Step-by-step explanation:
Given
Dolphin is 3.4 meters below the sea level
It started moving at a rate of [tex]-0.25\ m/s[/tex]
Distance travel in the vertical direction by dolphin is
[tex]\Rightarrow 9.9-3.4=6.5\ m[/tex]
time taken is given by
[tex]\Rightarrow time(t)=\frac{\text{Distance}}{\text{Speed}}\\\\\Rightarrow t=\frac{6.5}{0.25}=26\ s[/tex]

Answer:
14.4222051019 or 14.42
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 9^2 = 17^2
x^2 + 81 = 289
x^2 = 289 - 81
x^2 = 208
x = 14.4222051019 or 14.42

Josh and Bradley each bought a carton of milk. Their cartons were the same except that Bradley's carton was taller than Josh's. Each boy drank 1/4 of his milk carton. Did the each drink the same amount of milk? Explain.
Answer:
No
Because Bradley's carton is taller than Josh's, Bradley would drink more milk.
Let us assume that Bradley carton has 100 quarts . If he drank 1/4, he would drink 25 quarts of milk. If Josh carton is 80 quarts full of milk, he would drink 20 quarts of milk. this example shows that they would not drink the same amount of milk
Step-by-step explanation:
A taller carton would contain more ounces of milk.

A force of 20,000 N is exerted for 5.00 s, on a 75,000 kg mass. What is the impulse of the force for this 5.00 s ?
Answer:
Check pdf
Step-by-step explanation:
The impulse of the given force is required.
The impulse of the force which is being exerted on an object of 75000 kg is 100000 Ns.
ImpulseF = Force exerted on a body = 20000 N
t = Time the force was exerted for = 5.00 s
When finding the impulse of a force the mass of the object the force is being applied to does not matter. The only thing that can affect the force is if another force is being applied by the object which here is not doing so.
Impulse is given by
[tex]J=Ft\\\Rightarrow J=20000\times 5.00\\\Rightarrow J=100000\ \text{Ns}[/tex]
