work out the volume of this sphere.
give your answer to 1 decimal place
Answers
Answer:
[tex]Volume = 1436.3cm^3[/tex]
Step-by-step explanation:
Given
[tex]Radius = 7cm[/tex]
Required
Determine the volume
This is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex]
Substitute 7 for r
[tex]Volume = \frac{4}{3}\pi * 343[/tex]
Substitute 22/7 for [tex]\pi[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 343\\[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{1} * 49[/tex]
[tex]Volume = \frac{4312}{3}[/tex]
[tex]Volume = 1436.3333[/tex]
[tex]Volume = 1436.3cm^3[/tex] --- approximated

5^2+b^2=13^2 steps to solve
Answers
Answer:
b=12 or b=−12
Step-by-step explanation:
Answer:
Raise 5 to the power of 2.
25+b^2=132
Raise 13 to the power of 2.
25+b^2=169
Move all terms not containing b to the right side of the equation.
b^2=144
Take the square root of both sides of the equation to eliminate the exponent on the left side.
b=±√144
The complete solution is the result of both the positive and negative portions of the solution.
b=12,−12

3. The completion of a construction job may be delayed because of a strike. The probabilities are 0.60 that there will be a strike, 0.85 that the construction job will be completed on time if there is no strike, and 0.35 that the construction will be completed on time if there is a strike. What is the probability that the construction job will be completed on time
Answers
Answer:
0.55 = 55% probability that the construction job will be completed on time
Step-by-step explanation:
We have these following probabilities:
0.6 probability there is a strike. In this case, 0.35 probability that the construction will be completed on time.
1 - 0.6 = 0.4 probability that is not a strike. In this case, 0.85 probability that the construction will be completed on time.
What is the probability that the construction job will be completed on time?
[tex]p = 0.6*0.35 + 0.4*0.85 = 0.55[/tex]
0.55 = 55% probability that the construction job will be completed on time

Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Five minutes later, the tank contains 5 gallons of water.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answers
it will take 12 1/2 minutes to completely empty since it takes 2 1/2 minutes per gallon.
the tank was full 7 1/2 minutes before Jada arrived. 10-7= 3 so it emptied 3 gallons before Jada arrived. It takes 2 1/2 mins for a gallon to empty so 2 1/2 times 3 equals 7 1/2 mins

Angle S has a measure of 50°
Step-by-step explanation:
When comparing the angles of a triangle, they are written with the matching angles in the same order. (sorry for bad explanation here)
You have ∆ QRS as congruent to ∆ XYZ. This means angle Q is congruent to angle X, angle R is congruent to angle Y, and angle S is congruent to angle Z. As you can see in ∆ XYZ, angle Z is 50°. Therefore, angle S and angle Z are both 50° (but only angle S is an option)

Step-by-step explanation:
what is f?
So first, you have to distribute the minus in the middle. You ALWAYS have to. So when you do that, the minus changes to a plus, and everything on the right side of it changes from positive to negative or negative to positive. So it would turn into this -
(6f^2 - 9f + 10) + (2f^2 + f - 3)
Now, you can combine like terms. Add each one that matches. (Add the ones that have 1 f, or f^2)
Answer:
8f^2 - 8f + 7
