Answer:
The volume of the hemisphere
V = 121.33086 cubic centimeter
Step-by-step explanation:
Step(i):-
Given that the total surface area of a hemisphere = 45π cm²
The total surface area of a hemisphere = 3π r²
Equating
3π r² = 45π
[tex]r^{2} = \frac{45}{3} =15[/tex]
r = [tex]\sqrt{15} = 3.87[/tex]
The radius of the sphere 'r' = 3.87
Step(ii):-
The volume of the hemisphere
[tex]V = \frac{2}{3} \pi r^{3}[/tex]
[tex]V = \frac{2}{3} \pi (3.87)^{3}[/tex]
we know that π = 3.14
[tex]V = \frac{2}{3} (3.14) (3.87)^{3}[/tex]
V = 121.33086 cubic centimeter
Put the following lengths in ascending order, 900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km.
Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm
===========================================================
Explanation:
To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.
Here are some useful conversion factors
1 m = 100 cm1 m = 1000 mm1 km = 1000 mWith those conversion factors in mind, we get the following conversions:
900 cm = (900 cm)*(1 m/100 cm) = (900/100) m = 9 m8.9 m = already in meters, moving on895 cm = 8.95 meters; divide by 100 to convert from cm to meters as shown above9.1 m = already in meters, moving on12000 mm = (12000 mm)*(1 m/1000 mm) = (12000/1000) m = 12 m0.0092 km = (0.0092 km)*(1000 m/1 km) = (0.0092*1000) m = 9.2 mHere is the summary of the conversions:
900 cm = 9 m8.9 m = 8.9 m895 cm = 8.95 m9.1 m = 9.1 m12000 mm = 12 m0.0092 km = 9.2 mThe original list of
{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}
becomes this equivalent list
{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}
in that exact order.
After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of
{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}
Then you convert back each measurement to its original form
{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}
which is the final answer.

How many vehicles does the salesperson need to sell in a month to earn at least $6000? Explain how you found your answer.
Answer: 15 vehicles
Step-by-step explanation:
The first part of the question reads:
A salesperson at a car dealership earns a monthly salary of $2,400 and $250 for each vehicle sold.
The Sales person wants to get to $6,000 for the month.
Their salary already gives them $2,400 so the amount they have to make in commission is:
= 6,000 - 2,400
= $3,600
They earn $250 per car sold so the number of cars they need to sell is:
= 3,600 / 250
= 14.4
Round this up to 15 cars because rounding down to 14 would not be enough to reach the total of $6,000.
15 cars * $250 commission = $3,750 which is more than the $3,600 required so the condition has been satisfied.
To earn at least $6,000, they will have to sell 15 cars.

Write the following Arithmetic Sequence using a Recursive Formula: an = -7 + 3(n – 1)
a1 = 3, an = an-1 – 7
a1 = -7, an = an-1 + 3
a1 = -7, an = an+1 + 3
a1 = 3, an = an+1 – 7
9514 1404 393
Answer:
(b) a[1] = -7, a[n] = a[n-1] + 3
Step-by-step explanation:
Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...
an = a1 +d(n -1)
we see that the first term (a1) is -7, and the common difference (d) is +3.
The recursive version of the sequence definition is ...
a[1] = a1
a[n] = a[n-1] +d
So, the appropriate choice is ...
a[1] = -7, a[n] = a[n-1] +3

Answer:
+83
Step-by-step explanation:
The reason why it would be +83 is that it says that you walk UP 83 stairs.
And so from the word UP we know that the integer would be positive. And the number 83 represents how any stairs you walked up. So, it would be +83.

1. The current in a clothes washer is 15A when plugged into a 120V outlet. What is
the POWER of the washer? *
Answer:
Step-by-step explanation:
Power = Force × Velocity.
15*120=1800
To solve the problem we must know about resistance and power.
What is resistance?
Resistance is defined as the measurement that provides opposition to the current that travels through it.
It is given by the formula,
[tex]\rm Resistance = \dfrac{Voltage}{Current}[/tex]
The power of the washer is 1,800 watts.
Given to us
Current, I = 15 A
Voltage, V = 120V
Resistance Provided by the WasherUsing the formula of resistance to find the resistance,
[tex]\rm Resistance = \dfrac{Voltage}{Current}[/tex]
[tex]\rm Resistance = \dfrac{120\ V}{15\ A} = 8\ \Omega[/tex]
Thus, the resistance for the circuit will be 8 ohms.
Power of the washer[tex]\rm Power = (Current)^2 \times Resistance[/tex]
[tex]P = I^2 R\\\\P = (15)^2\times 8\\\\P = 1,800\ \rm watt[/tex]
Hence, the power of the washer is 1,800 watts.

Peter rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 11.
Answer:
[tex]\frac{25}{36}[/tex]
Step-by-step explanation:
Since each dice has a total of 6 numbers, Peter can get a maximum roll of 5 on each dice before the total is 11 or more. Therefore, the probability of rolling a number less than or equal to 5 each roll is 5/6. Now to find the probability of rolling a 5 or less in both rolls together so that the total is less than 11 we need to multiply the probability of each separate roll together.
[tex]\frac{5}{6} * \frac{5}{6} = \frac{25}{36}[/tex]
Therefore the probability of the total being less than 11 is [tex]\frac{25}{36}[/tex]

Evan uses 1/2 quart of yellow paint and adds 5 1/2 jars of red paint. They end up with the same volume of paint.
Answer:
answer is id.k
Step-by-step explanation:
The correct equation to represent the condition is,
⇒ 2 + 3 1/4x = 1/2 + 5 1/2x
And, The volume of the paint is, 2/3 quartz.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Liam and Evan are mixing paint. Liam uses 2 quarts of yellow paint and adds 3 1/4 jars of blue paint.
And, Evan uses 1/2 quart of yellow paint and adds 5 1/2 jars of red paint. They end up with the same volume of paint.
Let the volume of the paint is, x
Hence, We can formulate;
The correct equation to represent the condition is,
⇒ 2 + 3 1/4x = 1/2 + 5 1/2x
And, Solve for x as;
⇒ 2 + 13/4x = 1/2 + 11/2x
⇒ 2 - 1/2 = 11/2x - 13/4x
⇒ 3/2 = (44 - 26)x / 8
⇒ 12 = 18x
⇒ x = 12/18
⇒ x = 2/3
Hence, The volume of the paint is, 2/3 quartz.

In the school chorus, 3 9 of the students are fourth graders. In simplest form, what fraction of the students in the school chorus are fourth graders?
Answer: 1 / 3
Step-by-step explanation:
3/9 of the students in the school choir are fourth graders.
To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.
3 factors = 1 , 3
9 factors = 1, 3 , 9
Highest common factor = 3
Divide both numbers by 3
= (3/3) / (9/3)
= 1 / 3
Two-sixth of the mangoes ina basket are good. If the total number of magoes in the basket is 42 how many mangoes are bad
Answer:
28 bad mangoes
Step-by-step explanation:
Two-sixth of the mangoes ina basket are good. If the total number of magoes in the basket is 42 how many mangoes are bad
Step 1
We find the amount of mangoes that are good
Two-sixth of the mangoes in a basket are good = 2/6
Total number of mangoes = 42
Hence:
2/6 × 42 mangoes
= 14 good mangoes
Step 2
Find the number of bad mangoes
This is calculated as:
Total number of mangoes - Good Mangoes
= 42 mangoes - 14 good mangoes
= 28 bad mangoes
Therefore, the number of bad mangoes = 28
