In a class of 50 students, the number of students who offer accounting is twice as the number who offer economics.10 students offer neither of the subject and 5 students offer both subject. (i)illustrate the information on a Venn diagram. (ii) how many students offer accounting? (iii) how many students offer economics? (iv)how many students offer only 1 subject?
Answers
The Venn diagram shows that the number of students who offer accounting is 30.
How to explain the Venn diagram?It should be noted that a Venn diagram is an illustration which uses circles to show the relationship between the objects.
The number of students who offer accounting is:
= 25 + 5
= 30
The number of students who offer Economics is:
= 10 + 5
= 15
The number of students who offer only one subject will be:
= 25 + 10
= 35

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answers
Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex] πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V = [tex]\frac{4}{3}[/tex] × 3.14 × 9.3³
= [tex]\frac{4}{3}[/tex] × 3.14 × 804.357
= [tex]\frac{4(3.14)(804.357)}{3}[/tex]
≈ 3367.6 cm³ ( to the nearest tenth )
which is equivalent to 2/9

Answer:
D. 2%
Step-by-step explanation:
The growth rate can be found by looking at the growth factor of the exponential function.
f(x) = (initial value) × (growth factor)^x
The growth rate is related by ...
growth factor = growth rate + 1
This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.
__
We can write the function g(x) describing the table as ...
g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))
So, this could be ...
g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x
where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor
This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.
__
Then the difference between the growth rates of the two functions is ...
4% - 2% = 2% . . . . . matches choice D

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 9cm, and the base has a radius of 4cm. How much water is needed to fill 150 cups? Use 3.14 for π, and do not round your answer.
Answers
Answer:
22608cm³
Step-by-step explanation:
Step 1
We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.
Cup is shaped as a cone
The volume of a cone = πr²h/3
Where
r = radius = 4cm
h = height = 9cm
π = 3.14
Hence,
Volume of the cone (cup) =
3.14 × 4² × 9/3
= 150.72 cm³
Step 1
How much water is needed to fill 150 cups?
1 cup = 150.72 cm³ of water
150 cups = x
Cross Multiply
x = 150 × 150.72 cm³
x = 22608 cm³ of water
Therefore, 22608cm³ of water is needed to fill 150 cups

What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.
Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.
Let x be the length of the radius. Then we have
x² = 6² - 5²
x² = 36 - 25
x² = 11
x = √11
x = 3.316
x ≅ 3.3
