Answer:
(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)
For a sphere of radius R, the volume is:
V = (4/3)*pi*R^3
Where pi = 3.14
And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:
V = (1/2)*(4/3)*pi*R^3
We know that the volume of the hemisphere is 6 m^3, then we have the equation:
6 m^3 = (1/2)*(4/3)*3.14*R^3
Now we can solve this for R.
6 m^3 = 2.1*R^3
∛(6 m^3/2.1) = R = 1.41 m
The radius of the hemisphere is 1.41m
Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)
For a sphere of radius R, the surface is:
S = 4*pi*R^2
Then the surface of this sphere is:
S = 4*3.14*(1.41 m)^2 = 24.971 m^2

question
(60-5.8) ÷ 5 - 3^2
can you please explain it in an essay type like words and not just show me the answer I need it to show me how you got the answer don't give me just the answer
Answer:
1.84
Step-by-step explanation:
First you solve what is in the parenthesis.
60 - 5.8 = 54.2
The equation is now 54.2 ÷ 5 - 3^2
Now, you do the exponents. 3^2 = 9 since 3 to the second power is just another way to write 3 x 3.
Your equation is now 54.2 ÷ 5 - 9
You then divide 54.2 ÷ 5
54.2 ÷ 5 = 10.84
The last equation is 10.84 - 9
10.84 - 9 = 1.84
Answer:
Answer 1.84.

The first person's answer and explanation is correct.
the product of two consecutive integers is 120. write an equation to find the integers.
Answer:
The consecutive even integers are
n
n + 2
n(n + 2) = 120
n2 + 2n - 120 = 0
(n + 12)(n - 10) = 0
n = -12 or 10
Step-by-step explanation:
There are 2 solutions:
n = -12
n + 2 = -10
and
n = 10
n + 2 = 12

Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2 what is the maximum
Answer:
Maximum = 61.1
Step-by-step explanation:
Given - Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2
To find - What is the maximum ?
Proof -
We have to find which candidate got highest votes in the election .
For this, we first arrange all 15 in ascending order i.e. lowest to highest.
Now,
The arrangement is like this -
43.2,
43.4,
47.9,
49.2,
49.6,
49.7
50.1,
50.7,
51.2,
53.9,
55.1,
57.4,
58.8,
60.7,
61.1
From this , we get
Lowest votes = 43.2
Highest votes = 61.1
⇒Maximum = 61.1
A container of chocalates has a ratio of dark to milk chocolates of 3 to 5. If you have 18 dark chocolates, then how many milk chocolates do you have?
Answer:
30 milk chocolates
Step-by-step explanation:
We can set up the equation like this: 3*x=18
So we can solve that by 18/3 = 6
Now the mile chocolates are 5x, so if you multiply 5 by 6, you get 30
Write a fraction on the blank to make the comparison true .Use the fractions form the box .Explain how you choose your number 3/5>3-4
Answer:
Explained
Step-by-step explanation:
So I'm not sure if you mean by 3/4 or 3-4. But I'm going to assume that its 3-4 because 3/4 is greater than 3/5
3/5 is equal to 0.6 -> you can also find 0.6 by multiplying 3/5 * 2 on both sides which will be 6/10 which is 0.6
and 3-4 is - 1 (which is negative)
since 3/5 is positive and 3-4 is negative. You would know that this is true.

How much larger is the circumference of circle A than the circumference of circle B?
Give your answer to one decimal place.
diameter of circle A is 13 and B is 8
Answer:
Circumference of Circle A is about 16 units larger than the Circumference of Circle B
Step-by-step explanation:
Formula for Circumference of a circle = πd
Where, d = diameter of circle
Thus:
Circle A diameter = 13
Circle B diameter = 8
Therefore:
Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)
Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)
✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16
Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B

How to calculate the surface area of a sphere?The formula for the surface area of a sphere is:
Surface Area = 4πr²
Where r is the radius of the sphere.
Since the basketball has a diameter of 10 in, the radius is half of that, which is 5 in.
Substituting the radius into the formula, we get:
Surface Area = 4π(5²)
Surface Area = 4π(25)
Surface Area = 100π
Therefore, the surface area of the basketball is 100π in².
So the surface area is 100π in².

Write the slope intercept equation for this table
Answer:
y = 2x -4
Step-by-step explanation:
y2 - y1 / x2 - x1
-4 - (-6)/ 0 - (-1)
= 2
y = mx + b
y = -2x + b
-4 = -2(0) + b
-4 = 0 + b
-4 = b
So the equation is y = 2x -4

Team A and team B play in a competition Team A has 12 more points than team B Team A has twice as many points as team B How many points does each team have
Answer:
A = 24 points
B = 12 Points
Step-by-step explanation:
Team A and team B play in a competition
Team A has 12 more points than team B
A = B + 12
Team A has twice as many points as team B
A = 2B
We substitute
2B = B + 12
2B - B = 12
B = 12 points
Solving for A
A = 2B
A = 2 × 12
A = 24 points
