Answer:
15 kg
Step-by-step explanation:
Radius of a solid sphere : mass of a solid sphere
3 cm : 9 kg
Find the mass of a sphere of the same material of radius 5 cm
Radius of a solid sphere : mass of a solid sphere
5 cm : x kg
Equate both ratios to find x
3 cm : 9 kg = 5 cm : x kg
3/9 = 5/x
3 * x = 9 * 5
3x = 45
x = 45/3
x = 15 kg
The mass of a sphere of the same material of radius 5 cm is 15 kg
Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32

How do you factor trinomials? -
You factor trinomials by using methods like FOIL multiplication and simple factoring patterns.
How can we check the binomial factors to verify that they are truly factors?
We can multiply the binomial factors out to see that they are truly factors.
Create an example of a trinomial and factor it to its binomial factors.
+5x+6 factors into
(x+2)(x+3).
Sorry for the trashy answer.
Answer:
4.35pm is the later time, both buses were together back at the depot.
Reasons;
As bus b did not return his return route until 35 minute after departure.
We can say this was a return route taking 35 minute as the question does not point out length of time getting back. We therefore state it is a return route in the workings to explain how we found the answer.
Step-by-step explanation:
4.00 + 0.35 = 4.35 = b
4.00 + 0.15 = 4.15 = a
4.35 is the later time.
Answer:
16.34
Step-by-step explanation:
To find the answer, you multiply 3.8 (how much is in one gallon) by 4.3 (number of gallons) to get the answer of 16.34.
