What's The Volume Of The Cone? Round To Tenths Place Please.

Answers

Answer 1

Given:

Given that the radius of the cone is 2 inches.

The height of the cone is 4 inches.

We need to determine the volume of the cone.

Volume of the cone:

The volume of the cone can be determined using the formula,

[tex]V=\frac{1}{3} \pi r^2 h[/tex]

where r is the radius of the cone and h is the height of the cone.

Substituting r = 2 and h = 4 in the above formula, we get;

[tex]V=\frac{1}{3} (3.14) (2)^2 (4)[/tex]

[tex]V=\frac{1}{3} (3.14) (4) (4)[/tex]

[tex]V=\frac{1}{3}(50.24)[/tex]

[tex]V=16.75[/tex]

Thus, the volume of the cone is 16.75 cubic inches.

Answers

Final answer:

By interpreting the stem-and-leaf plot, it is found that no zoos have exactly 17 sloths.

Explanation:

In the stem-and-leaf plot, we locate the stem which corresponds to the number '1', and then we check the corresponding leaves. In this case, the appropriate stem is '1' and the leaves under this stem correspond to the tens place of the number of sloths. So, now we check the leaf '7' under stem '1'. Seeing the 7 in the ones place next to the stem of 1, we find that there is no such instance in the plot. Therefore, we can conclude that no zoos have exactly 17 sloths.

Maura can buy daffodil bulbs in packages of 3 for $5.37 or in packages of 2 for $4.52. How much money does she save by buying 30 bulbs at the better price?

Answers

Final answer:

Maura saves $14.10 by purchasing 30 daffodil bulbs in the more economical 3-bulb packages instead of the 2-bulb packages.

Explanation:

To determine how much Maura saves by buying 30 daffodil bulbs at the better price, we first need to calculate the price per bulb for each package option and then find the total cost for 30 bulbs. Let's compare the two package options:

Package of 3 bulbs for $5.37: The price per bulb is $5.37 / 3 = $1.79 per bulb.Package of 2 bulbs for $4.52: The price per bulb is $4.52 / 2 = $2.26 per bulb.

The package of 3 bulbs has a better price per bulb than the package of 2 bulbs. To buy 30 bulbs at the better price, Maura would need 10 packages of 3 bulbs, which will cost:

10 packages × $5.37 per package = $53.70

Now let's calculate how much it would cost if she bought the 2-bulb packages:

Since 30 is an odd number, Maura would need to buy 15 packages of 2 bulbs to get 30 bulbs. This will cost:

15 packages × $4.52 per package = $67.80

Maura saves by purchasing the 30 bulbs in 3-bulb packages:

$67.80 - $53.70 = $14.10

Therefore, Maura saves $14.10 by purchasing the 30 bulbs in the more economical 3-bulb packages.

A thanksgiving day promotion included $1 mail-in rebate for the purchase of a turkey wing at least 20 lb. Esther Robert purchased a 22-pound turkey for $1 and seventy-nine a pound. What did it cost for after rebate if an envelope cost $0.15 and a stamp cost $0.39?

Answers

Answer:

$38.92

Step-by-step explanation:

In this question, we are calculating the amount it would cost purchasing a turkey wing after giving some rebate.

Firstly, we calculate the cost of purchasing 22 pounds turkey

That would be 22 * $1.79 = $39.38

Now we subtract the cost of the rebate ;

That would be $39.38 -$1 = $38.38

Now, we add the envelope cost and the stamp cost

That would be $38.38 + $0.39 + $0.15 = $38.92

Final answer:

The final cost of the 22-pound turkey after accounting for the price per pound, mail-in rebate, and the costs of an envelope and stamp is $38.92.

Explanation:

The cost of a 22-pound turkey at $1.79 per pound is calculated first, then subtract the $1 mail-in rebate, and finally add the costs of the envelope and the stamp required for the rebate.

First, find the total cost of the turkey without the rebate:

22 pounds × $1.79 per pound = $39.38

Next, add the cost of the envelope and stamp:

Envelope: $0.15Stamp: $0.39Total for envelope and stamp: $0.15 + $0.39 = $0.54

After receiving the rebate of $1, the final cost is calculated:

Total cost before rebate: $39.38Total cost for envelope and stamp: $0.54Cost after rebate: ($39.38 + $0.54) - $1 = $38.92

Therefore, the final cost of the turkey after the rebate is $38.92.

10 inches
What is the length of the shortest side of the new triangle?

Answers

Final answer:

The shortest side of the new similar triangle, where the longest side is 9 inches, is found to be 4.8 inches. This is determined by using the scale factor 3/5, obtained from the original triangle with sides 15 inches, 8 inches, and 10 inches.

Explanation:

The student asks for the length of the shortest side of a new triangle similar to the one given, with the length of the longest side being 9 inches. To find this, we need to use the concept of similar triangles. Similar triangles have proportional corresponding sides.

The original triangle has sides of lengths 15 inches (longest side), 8 inches (shortest side), and 10 inches. Given that the longest side of the new triangle is 9 inches, we can find the scale factor by dividing the new longest side by the original longest side: 9 inches / 15 inches = 3/5.

Now, we use this scale factor to find the length of the shortest side in the new triangle: 8 inches (original shortest side) x 3/5 (scale factor) = 4.8 inches.

Therefore, the length of the shortest side of the new triangle is 4.8 inches.

If an object is projected upward from ground level with an initial velocity of 96 ft per​ sec, then its height in feet after t seconds is given by ​s(t)equalsminus16tsquaredplus96t. Find the number of seconds it will take to reach its maximum height. What is this maximum​ height?

Answers

Answer:

Number of seconds to reach maximum height = 3 seconds

Maximum height = 144 ft

Step-by-step explanation:

We are given that;

s(t) = -16t² + 96t

Now, s(t) is a function whose graph is an upside-down parabola, so the maximum s value occurs at the vertex.

Thus, the applicable formula for coordinate of vertex is t = -b/(2a) where a is the coefficient -16 and b is 96

Thus,t = -96/(2 x - 16)

t = 96/32

t = 3

Thus maximum height will be at 3 seconds.

Thus;

Max height = s(3) = -16(3)² + 96(3)

Max height = -144 + 288 = 144 ft

The object will reach its maximum height of 144 feet in 3 seconds.

Given information:

An object is projected upward from ground level with an initial velocity of 96 ft per​ sec.

The height in feet after t seconds is given by [tex]s(t)=-16t^2+96t[/tex].

Now, it is required to find the time at which the object will reach its maximum height.

The object will reach maximum height when velocity of the object becomes zero.

So, the velocity of the object can be written as,

[tex]s(t)=-16t^2+96t\\v(t)=\dfrac{d(s(t))}{dt}=-32t+96[/tex]

So, the time at maximum height can be calculated as,

[tex]v(t)=-32t+96=0\\t=3[/tex]

So, after 3 seconds the object will reach its maximum height.

Now, the maximum height of the object will be,

[tex]s(t)=-16t^2+96t\\s(3)=-16\times 3^2+96\times 3\\s(3)=144\rm \; ft[/tex]

Therefore, the object will reach its maximum height of 144 feet in 3 seconds.

D. (s × 2) - 12 = 38

Answers

The answer would be C. (12 x 5) - (s x 2) = 38.

This is because if there are 12 students with 5 pencils per student, we can say 12 x 5. Then, think of the phrase, two pencils lost per student. That would be 2s, or (s x 2). Since it’s lost, we would subtract that amount from 12 x 5.

People use water to​ cook, clean, and drink every day. An estimate of 26.5​% of the water used each day is for cleaning. If a family uses 68.9 gallons of water a day for cleaning​, how many gallons do they use every​ day?

Answers

Final answer:

To find the total daily water usage of the family, divide the amount of water they use for cleaning, 68.9 gallons, by the percentage of their total usage that goes to cleaning, which is 26.5%. The result is that the family uses about 260 gallons of water every day.

Explanation:

To calculate how many gallons of water the family uses every day, we need to establish the total daily water usage based on the percentage used for cleaning.

Since we know that 26.5% of their total water usage is allocated for cleaning, and they use 68.9 gallons for this purpose, we can find the total daily usage with a simple division:

Total daily water usage = Water used for cleaning / Percentage used for cleaning Total daily water usage = 68.9 gallons / 0.265 Total daily water usage = 260 gallons (rounded to the nearest whole number)

Thus, the family uses approximately 260 gallons of water per day for all their needs, including cooking, cleaning, and drinking.

Final answer:

To find out how many gallons a family uses every day, set up a proportion to find the total amount of water used for cleaning and solve for x. The family uses approximately 259.62 gallons of water every day.

Explanation:

To find out how many gallons a family uses every day, we need to determine the total amount of water used for cleaning. The question states that 26.5% of the water used each day is for cleaning, and the family uses 68.9 gallons for cleaning. We can set up a proportion to find the total amount of water used:

26.5% / 100% = 68.9 / x

Now we can solve for x by cross multiplying:

26.5x = 68.9 * 100

Dividing both sides of the equation by 26.5, we find that x is approximately 259.62.

Therefore, the family uses approximately 259.62 gallons of water every day.

Answer:

Hence the function only :

Secx and Cosx functions are symmetric about y-axis

And remaining functions are not symmetric about y-axis.

Step-by-step explanation:

Given:

Six circular function as :

y= sinx ,y=cosx , y=tanx,  y= cotx ,y=secx  y=cosecx

To Find:

Which functions are symmetric about the y-axis

Solution:

The function is said to be symmetric about the y-axis is given by

f(x)=f(-x)

Now

1)For y=sinx  i.e. f(x)=sinx

So put x=-x

f(-x)=sin(-x)

=-sinx

Hence f(x)≠f(-x)

This function is not symmetric about y-axis

2)For y=cosx ,i.e. f(x)=cosx

put  x=-x

f(-x)=cos(-x)...............(as value for x and -x cos value remain the same )

=cosx

hence f(x)=f(-x)

This function is symmetric to the y-axis

3)For y=tanx     i.e   f(x)=tanx

put  x=-x

f(-x)=tan(-x)

=-tanx

Hence f(x)≠f(-x)

This function is not symmetric about y-axis

4)For y=cotx  i.e.  f(x)=cotx

Using above observation,

f(x)≠f(-x)

This is not symmetric about y-axis

5)For y=secx  i.e f(x)=secx

f(x)=f(-x)

This function is symmetric about y-axis.

6) for y=cosecx

f(x)≠f(-x)

This function is not symmetric about y-axis

The admission fee at an amusement park is $1.50 for children and $4.00 for adults. On a certain day, 2,000 people entered the park, and the admission fees that were collected totaled $4,750. How many children and how many adults were admitted

Answers

Answer:

In that day 1300 children and 700 adults were admitted.

Step-by-step explanation:

Since the people who enter the park are either adults or children, the sum of these two types of people must be equal to the total amount that entered the park. So we have:

children + adults = 2000

The total amount collected must be the sum of the people that entered the park multiplied by the ticket fee for each type. We have:

1.5*children + 4*adults = 4750

We now have two equations and two variables so we can solve the system.

children + adults = 2000                                             equation 1

1.5*children + 4*adults = 4750                                     equation 2

We can multiply the equation 1 by -1.5 and sum it with the equation 2 to solve for adults, we have:

-1.5*children - 1.5*adults = -3500

1.5*children + 4*adults = 4750

2.5*adults = 1750

adults = 1750/2.5 = 700

To solve for children we apply the found value for adults on the equation 1.

children + 700 = 2000

children = 2000 - 700 = 1300

In that day 1300 children and 700 adults were admitted.

Answer:

700 adults and 1300 children

Step-by-step explanation:

Let 'C' represent number of children

'A' represent number of adults

->If  2,000 people entered the park, the equation will be

C+A=2000

C=2000-A ->eq(1)

->$1.50 for children and $4.00 for adults.

$1.50C+$4.00A=$4,750

Substituting for C from above.

$1.50(2000-A)+$4.00A= $4,750

$3000-$1.50A+$4.00A=$4,750

$2.50A = $4,750 - $3000

$2.50A=$1750

A= 700

and for children:

eq(1)=>

C=2000-700

C= 1300

Thus, 700 adults and 1300 children were admitted.

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

Solution to the problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by [tex]\alpha=1-0.99=0.01[/tex] and [tex]\alpha/2 =0.005[/tex]. And the critical value would be given by:

[tex]z_{\alpha/2}=-2.58, z_{1-\alpha/2}=2.58[/tex]

Part a

The margin of error for the proportion interval is given by this formula:  

[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]    (a)  

And on this case we have that [tex]ME =\pm 0.05[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex]   (b)  

And replacing into equation (b) the values from part a we got:

[tex]n=\frac{0.58(1-0.58)}{(\frac{0.05}{2.58})^2}=648.600[/tex]  

And rounded up we have that n=649

Part b

For this case we can use an estimator for p as [tex]\hat p=0.5[/tex]

[tex]n=\frac{0.5(1-0.5)}{(\frac{0.05}{2.58})^2}=665.64[/tex]  

And rounded up we have that n=666


The volume of a cylinder is 480 cm. The height of the cylinder is 30 cm. What is the radius of the
cylinder?
The radius of the cylinder is cm. (Simplify your answer.)

Answers

Answer:

Step-by-step explanation:

Given

Volume of Cylinder (V)= 480 cm

height (h) = 30 cm

radius (r) = ?

WE KNOW THAT WE HAVE FORMULA

Volume (V) = [tex]\pi r^{2} h[/tex]

           480 = 3.14 * r^2 *30

            480 = 94.2 r^2

             480/94.2 = r^2

               r^2 = 5.1

                 r =[tex]\sqrt{5.1}[/tex]

Therefore r = 2.3 cm

5.Find the domain of the following function:

y=x+2
__________
x^2 + 2x −8

Select the appropriate response:

A) x equals −4, 2
B) x cannot equal −4, 2
C)Not possible to solve

Answers

Answer:

(-∞,∞)

B) x cannot equal -4, 2

Step-by-step Explanation:

The function, y = x + 2, has a domain of (-∞,∞) because the equation will remain true no matter number you plug for x.

For the second question, x would be equal to -2 and 4.  You can find this by factoring the equation.  x² + 2x - 8 = (x - 2)(x + 4)  Your answer should be B

Answer:

B) x cannot equal −4, 2

Step-by-step explanation:

x² + 2x - 8 = 0

When x = -4, 2

When the denominator becomes zero, function becomes undefined

A random sample of 64 students at a university showed an average age of 25 years and a sample standard deviation of 2 years. The 98% confidence interval for the true average age of all students in the university is:________
a. 20.0 to 30.0
b. 20.5 to 26.5
c. 23.0 to 27.0
d. 24.4 to 25.6

Answers

Answer:

The correct option is;

d. 24.2 to 25.6

Step-by-step explanation:

Here we have a sample with unknown population standard deviation, we therefore apply the student t distribution at 64 - 1 degrees of freedom

Therefore, we have

[tex]CI=\bar{x}\pm t\frac{s}{\sqrt{n}}[/tex]

Where:

[tex]\bar x[/tex] = Mean = 25

σ = Standard deviation = 2

n = Sample size = 64

t = T value at 98% = [tex]\pm 2.387[/tex]

Which gives

[tex]CI=25\pm t_{63}\frac{2}{\sqrt{64}}[/tex]

That is the value is from

24.40325 to 25.59675 which gives,by rounding to one decimal place, is

24.4 to 25.6.

The 98% confidence interval for the true average age of all students at the university, given a sample mean age of 25, standard deviation of 2, and a sample size of 64, is approximately option (d) 24.4 to 25.6 years.

The 98% confidence interval for the true average age of all students in the university can be calculated using the sample mean, the sample standard deviation, and the size of the sample. Since the population standard deviation is unknown and the sample size is less than 30, we use the t-distribution to find the critical value (t).

First, we find the t-score corresponding to a 98% confidence level with 63 degrees of freedom (n-1 = 64-1). Using a t-distribution table or calculator, the t-score is approximately 2.390.

Next, we calculate the margin of error (ME) using the formula:
ME = t * (s/√n)
where s is the sample standard deviation and n is the sample size. Plugging in our numbers:
ME = 2.390 * (2/√64) = 0.5975

Finally, we add and subtract this margin of error from the sample mean to find the confidence interval:
CI = mean ± ME
CI = 25 ± 0.5975
CI = (25 - 0.5975, 25 + 0.5975)
CI = (24.4025, 25.5975)

Therefore, the 98% confidence interval for the true average age is approximately 24.4 to 25.6 years.
