A popcorn cup is in the shape of a cone. The slant height of the cone is 9 inches, and the diameter is 6.2 inches. What is the volume of the cone? Use pi equals 3.14. help
Answer:
V = 262.61 m³
Step-by-step explanation:
Given: Slant height of the cone is 9 inches, the diameter is 6.2 inches.
To find: Volume of the cone
Formula: The formula for the volume of a cone is V = 1/3hπr².
Solve: The base area of the cone. π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however, the value 3.14 is often used.
V = π × r² × h / 3
π × r²
V = 262.610935 m³
In the nearest tenths, the volume of the cone is V = 262.61 m²

Answer:
area: 524 cm²perimeter: 124.8 cmStep-by-step explanation:
The rectangle in the middle has a width equal to the radius of the semicircular ends, so (20 cm)/2 = 10 cm.
The semicircular ends, together, make a complete circle of radius 10 cm.
The area is the sum of the areas of the parts:
A = LW = (21 cm)(10 cm) = 210 cm² . . . . . . rectangle area
A = πr² = π(10 cm)² = 100π cm² ≈ 314 cm² . . . . . circle area
The total area is ...
210 cm² +314 cm² = 524 cm² . . . . area of the figure
__
The perimeter of the figure is the sum of the lengths of all of the edges. From the left, working clockwise, we have ...
P = (1/2 circle of diameter 20) + (rectangle top = 21) +(1/2 circle of diameter 20) +(circle radius = 10) +(rectangle bottom = 21) +(circle radius = 10)
The two 1/2 circles add to a whole circle with a circumference of ...
C = πd = (3.14)(20 cm) = 62.8 cm
Then the whole perimeter is ...
P = 62.8 cm + 21 cm + 10 cm + 21 cm + 10 cm = 124.8 cm

Note that we have used 3.14 for pi. If you use a more exact value, your answers will be slightly different.

15 people working 5 hours per day can make 30 units of a product in 10 days. Assuming all other factors remaining
constant and people of same efficiency are used to make the same products, in how many days can 10 people
make 10 units of the product if each of them works 10 hours per day?
SELECT ONLY ONE
2.5 days
7.5 days
12 days
26 days
The required number of days is 2.5 days
First, we need to calculate the amount of units generated per day.
If 15 people working 5 hours per day can make 30 units of a product in 10 days, then the amount of units per day is calculated as:
Units per day = (15*5*10)/30
Units per day = 750/30
Units per day = 25 units/day
If people of the same efficiency are used to make the same products, the number of days needed by 10 people to make 10 units of the product if each of them works 10 hours per day will be;
Number of days = (25*10)/10*10
Number of days = 250/100
Number of days = 2.5 days
Hence the required number of days is 2.5 days

A picture is to be printed onto a sheet of paper with dimensions of 81/2 x 11 inches, A margin of 1 1/2 inches is to be left on all sides of the picture. What is the area of the printed picture?
Answer:
The area of the printed picture is 172.5 square inches.
Step-by-step explanation:
Since a picture is to be printed onto a sheet of paper with dimensions of 81/2 x 11 inches, and a margin of 1 1/2 inches is to be left on all sides of the picture, to determine what is the area of the printed picture the following calculation must be carried out, knowing that the area of a rectangle is equal to the base multiplied by the height:
81/2 = 40.5
1/2 = 0.5
40.5 - 1.5 x 4 = 34.5
11 - 1.5 x 4 = 5
34.5 x 5 = 172.5
Therefore, the area of the printed picture is 172.5 square inches.

Answer:
4th number line (the one of the bottom right)
Step-by-step explanation:
First, solve the inequality, then choose the number line that mathes the solution.
3x ≤ -6
Only step: Divide by 3.
x ≤ -6/3
x ≤ -2
But which number line matches the solution?
We know this is going left, so #1 & #3 are out. This also has a closed circle (because of ≤ (less than/equal to)), so #2 is also out.
Number line #4 matches the solution (x ≤ -2), so it is the answer.

investing $27,000 in an account paying 7.25% interest compounded quarterly.
What will Jamie's account balance be in 14 years?
Answer:
$74,495.30
Jamie's account balance will be $73,828.74 after 14 years.
What is Compound Interest?
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Here, Principal = $27,000
Rate of interest = 7.25% compounded quarterly
= 0.0725/4 = 0.018125 per annum
Time = 14 years or 56 quarters
Now, A = P(1+i)ⁿ
A = 27000(1+0.018125)⁵⁶
A = 27000 X 2.7343
A = 73828.74
Thus, Jamie's account balance will be $73,828.74 after 14 years.

Consider a taxi station where taxis and customers arrive in accordance with Poisson processes with respective rates of one and three per minute. A taxi will wait no matter how many other taxis are present. However, an arriving customer that does not find a taxi waiting leaves. Find the proportion of arriving customers that get taxis.
Answer:
The proportion of arriving customers that get taxis is:
= 33%.
Step-by-step explanation:
Rate of arrival of taxis = 1 per minute
In one hour, the number of taxis arriving = 60 (60/1)
Rate of arrival of customers = 3 per minute
In one hour, the number of customers arriving = 180 (60 * 3)
The proportion of arriving customers that get taxis = 60/180
= 0.333
= 33%
b) Since the taxis wait until they get a customer, it means that they will likely transport one out of 3 customers who arrive. Therefore, the proportion of arriving customers that get taxis is equal to 1/3 or 60/180, which is equal to 33%.
