A right circular cone has a height of 10 centimeters and a base of 9cm. What is the volume of the cone
Answer:
19cm
Step-by-step explanation:
The volume of the give cone is 21.40 cm³
What is a cone?A cone is a shape formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base(which does not contain the apex). The distance from the vertex of the cone to the base is the height of the cone.
Given that, A right circular cone has a height of 10 centimetres and a base of 9 cm.
The circumference of the base is 9 cm
Therefore, 2πr = 9
r = 9/3.14×2
r = 1.43 cm
Volume of a cone = πr²h/3
V = 3.14(1.43)²10/3
V = 21.40 cm³
Hence, The volume of the give cone is 21.40 cm³

A cylinder has a 21.02 in. diameter. The linear speed of a point on the cylinder's surface is 18.12 ft/sec. What is the angular speed of the cylinder, in revolutions per hour?
Answer:
11860.22 rev/hour
Step-by-step explanation:
The diameter if a cylinder, d = 21.02 inches
Radius, r = 10.51 inches
or
r = 0.875 feet
The linear speed of a point on the cylinder's surface is 18.12 ft/sec.
We need to find the angular speed of the cylinder.
The relation between the linear speed and the angular speed is given by :
[tex]v=r\omega[/tex]
Where
[tex]\omega[/tex] is angular speed
[tex]\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s[/tex]
or
[tex]\omega=11860.22\ rev/hour[/tex]
So, the required angular speed of the cylinder is 11860.22 rev/hour.

The
average GPA was 2.38 with a standard deviation of 0.59, what is the margin of error? Round
your answer to three decimal places.
Answer:
The margin of error = 0.037
Step-by-step explanation:
Explanation:-
Given that the mean of the Population(μ) = 2.38
Given that the standard deviation of the Population(σ) = 0.59
Given sample size 'n' = 950
Level of significance = 0.05
The critical value( Z₀.₀₅) = 1 .96
The margin of error is determined by
[tex]M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }[/tex]
[tex]M.E = \frac{1.96 (0.59)}{\sqrt{950} }[/tex]
M.E = 0.037
Final answer:-
The margin of error = 0.037

Caroline won $205000 in a lottery. After paying $96000 in taxes, she placed the remaining amount in a savings account at a 2% interest rate. How much interest will the account earn after just 6 months?
Answer: $1090
Step-by-step explanation:
Since Caroline won $205000 in a lottery and then paid $96000 in taxes, the remaining amount will be:
= $205000 - $96000
= $109000
The interest that the account will earn after just 6 months will be:
Interest = PRT
= 109000 × 2% × 6/12
= 109000 × 0.02 × 0.5
= $1090
Martina has two dogs. The ratio of the dogs’ weights is 2:3. If the
total weight of the two dogs is 40 pounds, how much does each
dog weigh?
Answer:
Dog 1: 16 pounds
Dog 2: 24 pounds
Step-by-step explanation:
2x+3x=40
5x=40
x=8
2x = 16
3x=24
Answer:
The dogs' weights are 16 pounds and 24 pounds
Step-by-step explanation:
Equations:
Martina has two dogs. Their combined weight is 40 pounds. Let's set:
x = weight of one of the dogs.
40-x = weight of the other dog
The ratio between them is 2:3, thus:
[tex]\displaystyle \frac{x}{40-x}=\frac{2}{3}[/tex]
Cross multiplying denominators:
3x = 2(40 - x)
Operating:
3x = 80 - 2x
Adding 2x:
5x = 80
Dividing by 5:
x = 80/5 = 16
x = 16 pounds
The weight of the other dog is 40-16=24 pounds.
The dogs' weights are 16 pounds and 24 pounds

Answer:
67.31
Step-by-step explanation:
27% of $53 is 14.31
$53+$14.31=$67.31
Answer:
$68.05
Step-by-step explanation:
To find out what the total cost of the meal is, multiply 1.07 by 53 * 1.2. I'd multiply 53 by 1.2 first, then multiply the product of that by 1.07.
(53 * 1.2) * 1.07 (Convert 1.2 into 6/5, and 1.07 into 107/100.)
((53 * 6)/5) * 107/100 (Multiply 53 by 6 to get 318.)
318/5 * 107/100 (Cross cancel if needed.)
159/5 * 107/50 (Multiply 159 by 107 to get 17013.)
17013/(5 * 50) (Multiply 5 by 50 to get 250)
17013/250 (Divide 17013 by 250 to get 68.052)
68.052 (Round to the nearest cent)
The meal costs $68.05 in total.
Holiday dinners at June’s house are always a festive occasion. One particular holiday, June has 16 guests.
June offers the guests apple pie and blueberry pie. While any guest can have slices of both pies, June never serves a particlar guest more than one slice of each pie and each guest is allowed to decline any slice of pie they don’t care for.
June serves a total of 10 slices of apple pie and a total of 11 slices of blueberry pie.
June serves 8 guests slices of both pies.
How many guests had no pie at all?
a. 3
b.2
c.0
Answer:
a. 3
Step-by-step explanation:
We solve this question gathering the information given in the question.
June serves 8 guests slices of both pies.
This is soon going to be used
June serves a total of 10 slices of apple pie
This includes the 8 guests which got served both pieces. So 10 - 8 = 2 guests were served only apple pie.
11 slices of blueberry pie.
By the same logic as above, 11 - 8 = 3 guests were served only blueberry pie.
So
8 + 2 + 3 = 13 guests were served at least one pie.
16 - 13 = 3 guests had no pie at all.
