Use two formulas for volume to find the volume of the figure. Express the answer in terms of x and then round to nearest whole number.
Answer:
Volume of the figure = 341.3π + 1,280π = 1,621.33π
Volume of the figure to the nearest whole number = 1,621π m³
Step-by-step explanation:
The figure shown is composed of a hemisphere and a cylinder.
The volume of the figure = volume of hemisphere + volume of cylinder
Volume of the hemisphere = ⅔πr³
Radius (r) of hemisphere = 16/2 = 8 m
Volume of hemisphere = ⅔*π*8³ = ⅔*π*512 = 341.33π m³
Volume of Cylinder = πr²h
radius (r) = 16/2 = 8 m
height (h) = 20 m
Volume of cylinder = π*8²*20 = 1,280π m³
Volume of the figure = 341.3π + 1,280π = 1,621.33π
Volume of the figure to the nearest whole number = 1,621π m³

Solve four sixths plus one third
Answer:
1
Step-by-step explanation:
1 is the solution of four sixths plus one third
What is Number system?A number system is defined as a system of writing to express numbers.
We need to solve for four sixths plus one third
four sixths is nothing four by six
4/6
One third is 1/3
Four sixths plus one third
4/6+1/3
LCM of 6 and 3 is 6
4+2/6
6/6=1
Hence, 1 is the solution of four sixths plus one third

There are 720 dishes that need to be rinsed. Brian can rinse them in 72 minutes by himself. It will take his friend Boris 144 minutes to rinse these dishes. How
long will it take them itthey rinse these 720 dishes together?
minutes
Answer:
It will take both of them 48 minutes to rinse all the dishes.
Step-by-step explanation:
Brian can do 720/72 = 10 dishes per minute.
Boris can do 720/144 = 5 dishes per minute
Together, they do 15 dishes per minute
720/15 = 48 minutes
kelly flies a distance of 2,100 miles. The trip takes 4 2/3 hours.
What is the airplane's unit rate of speed in miles per hour?
Answer:
450 miles per hour
Step-by-step explanation:
Kelly flies at a distance of 2,100 miles
The time taken for the trip is 4 2/3 hours
Therefore the rate of speed can be calculated as follows
= 2,100 ÷ 4 2/3
= 2,100 ÷ 14/3
= 2100 × 3/14
= 150 × 3
= 450 miles per hour

A random sample of 5 homes in Newberry, Florida had a mean of $169,900 and a standard deviation of $21,756. Construct a 95% confidence interval for the average home of this size in Newberry.
A. (144885.25, 194914.75).
B. (150440.842, 189359.16).
C. (150830, 188969.98).
D. (142886, 196914).
Answer:
D. (142886, 196914).
Step-by-step explanation:
To solve for this question, we would use t score instead of z score. The reason is because, our sample size is small.
The formula for Confidence Interval =
C.I = Mean ± t score × standard deviation/√n
n = 5 samples
Degrees of freedom = n - 1 = 5 - 1 = 4
The t score for a 95% confidence interval with degrees of freedom 5 is : 2.776
Hence,
Confidence Interval =
169,900 ± 2.776 × 21,756/√5
169,900 ± 2.776 × 9.7295789837
169, 900 ± 27009.311259
Confidence Interval
169,900 - 27009
= 142886
169, 900 + 27009.311259
= 196914
Hence, the confidence interval = (142886, 196914)
Option D is the correct answer
Using the t-distribution, it is found that the 95% confidence interval for the average price of a home of this size in Newberry is of (142886, 196914), given by option D.
In this problem, we have the standard deviation for the sample, thus, the t-distribution is used to solve this question.
The sample mean is [tex]\overline{x} = 169900[/tex].The sample standard deviation is [tex]s = 21756[/tex].The sample size is [tex]n = 5[/tex]First, we find the number of degrees of freedom, which is the sample size subtracted by 1, so df = 5 - 1 = 4.
Then, we find the critical value for the 95% confidence interval with 4 df, which looking at the t-table or using a calculator is given by t = 2.7765.
The margin of error is:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
In this case:
[tex]M = 2.7765\frac{21756}{\sqrt{5}} = 27014[/tex]
The confidence interval is:
[tex]\overline{x} \pm M[/tex]
Then
[tex]\overline{x} - M = 169900 - 27014 = 142,886[/tex].
[tex]\overline{x} + M = 169900 + 27014 = 196,914[/tex].
Thus, the correct option is D. (142886, 196914).
