Two similar cones have volume of 343pi cubic centimeters and 512pi cubic centimeters. The height of each cone is equal to 3 times its radius. Find the radius and height of both cones

Answers

Answer 1

Answer:

For the first cone: r = 7 cm, h = 21 cm

For the second cone: r = 8 cm, h = 24 cm

Step-by-step explanation:

The volume of the first cone is [tex]343\pi cm^3[/tex]

The volume of the second cone is [tex]512\pi cm^3[/tex]

We are told that the height of each cone is 3 times its radius, hence:

h = 3r

The volume of a cone is given as:

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

Substituting h = 3r:

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

For the first cone, V = [tex]343\pi cm^3[/tex], radius, r, will be:

[tex]343\pi = \pi r^3\\\\\\=> r^3 = 343\\\\\\r = \sqrt[3]{343} \\\\\\r = 7 cm[/tex]

∴ Its height will be:

h = 3r = 3 * 7 = 21 cm

For the second cone, V = [tex]512\pi cm^3[/tex], radius, r, will be:

[tex]512\pi = \pi r^3\\\\\\=> r^3 = 512\\\\\\r = \sqrt[3]{512} \\\\\\r = 8 cm[/tex]

∴ Its height will be:

h = 3r = 3 * 8 = 24 cm

The radius and height of the first cone are 7 cm and 21 cm respectively while the radius and height of the second cone are 8 cm and 24 cm respectively.

Answers

Answer:

They predict 1350 renters will buy liability insurance.

The answer is 1350 renters.

Step-by-step explanation:

Given:

A car rental company at the local airport estimates they sell liability insurance to 45% of their customers.

If they rent 3,000 cars next month.

Now, to find the renters they predict will buy liability insurance.

So, the rate of the car rental company which estimates of selling liability insurance to their customers is 45%.

And, the cars they rent next month = 3,000.

Now, to get the renters they predict of buying liability insurance by getting the rate of the cars they rent next month:

[tex]45\%\ of\ 3,000\\\\=\frac{45}{100}\times 3,000\\\\=0.45\times 3,000\\\\=1350.[/tex]

A cylindrical drinking glass can hold 56.52 cubic inches of
water. The diameter of the glass is 3 in. How tall is the glass?
Use 3.14 for T.
A. 4 inches
B. 6 inches
CC. 7 inches
D. 8 inches

Answers

Answer:

The answer is

D. 8 inches

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder this time.

Given data

Volume of cylindrical shape v=

56.52 inch³

Diameter of cylindrical glass d= 3

inch

But raduis r =diameter/2=3/2= 1.5

inch

We know that the the expression for the volume of a cylinder is given as

v= πr²h

Substituting our given data to solve for the height h

56.52= 3.14*(1.5)²*h

56.52= 7.065h

h= 56.52/7.065

h= 8 inches

Final answer:

To calculate the height of the cylindrical glass, use the volume formula with the radius from the diameter, and solve for the height. The final calculation shows that the glass is 8 inches tall, corresponding to option D.

Explanation:

To find the height of a cylindrical drinking glass given its volume and diameter, we can use the formula for the volume of a cylinder: V = πr²h, where V is the volume, π (pi) is a constant approximated as 3.14, r is the radius of the cylinder, and h is the height of the cylinder.

Since the diameter is given as 3 inches, the radius r is half of that, which is 1.5 inches. By substituting the values into the formula and solving for h, we get:

V = πr²h

56.52 = 3.14 × (1.5)² × h

56.52 = 3.14 × 2.25 × h

56.52 = 7.065 × h

h = 56.52 / 7.065

h = 8 inches

Therefore, the height of the drinking glass is 8 inches, which corresponds to choice D.

Find the accumulated value of an investment of 15,000 for 4 years at an interest of 4% if the money is a. Compound semiannually; b. Compounded quarterly; c. Compounded monthly; d. Compounded continuously.

Answers

Answer:

Compounded Semiannually: $17,574.89

Compounded Quarterly: $17,588.68

Compounded Monthly: $17,597.98

Compounded Continuously: $17,602.66

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 4% into a decimal:

4% -> [tex]\frac{4}{100}[/tex] -> 0.04

Now, plug in the values to the equation:

Compounded Semiannually:

[tex]A=15,000(1+\frac{0.04}{2})^{2(4)}[/tex]

[tex]A=17,574.89[/tex]

Compounded Quarterly:

[tex]A=15,000(1+\frac{0.04}{4})^{4(4)}[/tex]

[tex]A=17,588.68[/tex]

Compounded Monthly:

[tex]A=15,000(1+\frac{0.04}{12})^{12(4)}[/tex]

[tex]A=17,597.98[/tex]

To find the value if compounded continuously, use the following formula:

[tex]A = Pe^{rt}[/tex]

[tex]A=15,000e^{0.04(4)}[/tex]

[tex]A=17,602.66[/tex]

Final answer:

The accumulated value of an investment is calculated differently depending on the compounding period - semiannually, quarterly, monthly or continuously. This involves the compound interest formula and understanding of how interest rates work.

Explanation:

The subject of this question is about calculating the accumulated value of an investment at a given interest rate with various compounding periods i.e., semiannually, quarterly, monthly, and continuously. We first need to understand that compound interest is calculated on the principal plus the accumulated interest.

To calculate the future value of the investment, we use the compound interest formula: P*(1+r/n)^(nt), where P is the principal (or initial investment), r is the annual interest rate (in decimal form), n is the number of compounding periods per year, and t is the time in years.

Semiannually: P*(1+r/2)^(2*4)Quarterly: P*(1+r/4)^(4*4)Monthly: P*(1+r/12)^(12*4)Continuously: P*e^(rt), where e is Euler's number, approximately equal to 2.71828.

Answers

Final answer:

The simplified expression for the number of moons of Neptune, based on the variable for Mars' moons m, is 6m + 2, meaning Neptune has twice as many moons as Mars plus two more.

Explanation:

The student has asked to write and interpret a simplified expression that represents the number of moons of Neptune, based on the information that Mars has m moons, Pluto has one more than twice the number of moons of Mars, and Neptune has one less than three times the number of moons of Pluto.

Let's denote the number of moons of Mars as m. According to the information, Pluto has 2m + 1 moons. Therefore, Neptune would have 3(2m + 1) - 1 moons. Simplifying this expression:

Neptune's moons = 3(2m + 1) - 1

= 6m + 3 - 1

= 6m + 2

The simplified expression 6m + 2 represents the number of moons of Neptune, which means that Neptune has twice as many moons as Mars plus an additional two moons.

Quentin was challenged to a half- court shooting competition. He will earn 20 points for every shot made and lose 5 points for every shot missed. Quentin has zero points. How many shots did he make

Answers

Answer:

Quentin made a total of 4 shots

Step-by-step explanation:

The complete question is as follows;

Quentin was challenged to a half-court shooting completion. For every half-court shot he makes, he will earn 20 points. For each half-court shot he misses, he will lose five points. After 20 half-court shots, Quentin has zero points. How many half-court shots did he make?

Now let's answer;

Let the number of shot he makes be x and the number of shot he misses be y

For every shot made, we have +20, for every shot missed, we have -5

Firstly we know that adding both numbers would give 20.

Mathematically;

x + y = 20        (i)

Now, we add the number of points he made to the number of points he missed to give a total of 0

Mathematically, that would be;

+20x -5y = 0  (ii)

from i, y = 20-x

Substitute this in ii

20x -5(20-x) = 0

20x - 100 + 5x = 0

25x = 100

x = 100/25

x = 4

This means that he made 4 shots

To make banana berry smoothies, Just Juice mixes water and juice in a ratio of 5 to 3. How much water and juice should Just Juice mix to make 104 quarts of banana berry smooties?

65 quarts of water and 39 quarts of juice are required to make 104 quarts of banana berry smoothies

Step-by-step explanation:

Given:

Ratio of water and juice in banana berry smoothies = [tex]5:3[/tex]

To find:

Amount of water and juice required to make 104 quarts of banana berry smoothies

Solution:

Amount of water required to make 104 quarts of banana berry smoothies = [tex]\frac{5}{8}[/tex]×104 = 5×13 = 65 quarts

Amount of juice required to make 104 quarts of banana berry smoothies = [tex]\frac{3}{8}[/tex]×104 = 3×13 = 39 quarts

So,

65 quarts of water and 39 quarts of juice are required to make 104 quarts of banana berry smoothies.

Final answer:

To make 104 quarts of banana berry smoothies with a water to juice ratio of 5:3, Just Juice should mix 65 quarts of water with 39 quarts of juice.

Explanation:

To make banana berry smoothies with a mix of water and juice in a ratio of 5 to 3, and to create a total of 104 quarts, we need to find the amount of water and juice separately. Since the total parts of the ratio is 5 parts water plus 3 parts juice, which equals 8 parts, we can calculate the amount of each as follows:

Divide the total amount of smoothie by the total number of parts: 104 quarts / 8 parts = 13 quarts per part.Multiply the quarts per part by the number of parts for water: 13 quarts x 5 parts = 65 quarts of water.Multiply the quarts per part by the number of parts for juice: 13 quarts x 3 parts = 39 quarts of juice.

Therefore, Just Juice should mix 65 quarts of water with 39 quarts of juice to make 104 quarts of banana berry smoothies.

Thomas rays parents begin saving to buy their son a car for his 16th birthday. they save $800 the first year and each year they save 5% more than the previous year. How much money will they have saved for his 16th birthday.

Answers

Answer:

money they will have saved for his 16th birthday = $18,926

Step-by-step explanation:

This is a geometric series problem.

The sum of a geometric series is given by the formula;

Sn = a1•(rⁿ - 1)/(r - 1)

Where;

a1 is the first term

n is the number of terms

r is the constant ratio

Now, in this question, they started saving since he was born till his 16th birthday. That's 16 years. Thus number of terms; n = 16

Also, the first money saved was $800, thus the first term; a1 = 800

They save 5% more each year than the previous year. That's an increase of 1.05 each year. Thus, the common ratio; r = 1.05

The amount of money they will have by his 16th birthday will be;

S_16 = 800•(1.05^(16) - 1)/(1.05 - 1)

S_16 = 800(1.18287458838/0.05)

S_16 = $18,926

S16 = $800·(1.05^16 -1)/(1.05 -1)

-The margin of error is calculated using the formula:

[tex]ME=z_{\alpha/2}\times \frac{\sigma}{\sqrt{n}}\\\\[/tex]

-We substitute the values, n=900 and ME=30 in the formula to solve for standard deviation:

[tex]ME=z_{\alpha/2}\times \frac{\sigma}{\sqrt{n}}\\\\\\30=1.645\times\frac{\sigma}{\sqrt{900}}\\\\\sigma=\frac{30^2}{1.645}\\\\=547.1125[/tex]

Hence, the population standard deviation is 547.1125

If you were to plot the point (4,-12) what would be the correct method?

Answers

Answer: it is the last one

Step-by-step explanation:

If you were to plot the point (4,-12), the correct method is to plot the point 4 units right, then 12 units down

Option D is correct

If a point is expressed in the form (x, y), the coordinate x represents the location of the point on the horizontal axis while the coordinate y represents the location of the point on the vertical axis

If x is positive, it means that the point is plotted on the right hand side of the horizontal axis. If x is negative, it means that the point is plotted on the left hand side of the horizontal axis

If y is positive, it means that the point is plotted on the  top region of the vertical axis. If y is negative, it means that the point is plotted on the bottom region of the vertical axis

For the point (4, -12)

x = 4, and y = -12

Since x = 4 is positive, the graph is plotted 4 units to the right

Since y = -12 is negative, the graph is plotted 12 units down

Therefore, If you were to plot the point (4,-12), the correct method is to plot the point 4 units right, then 12 units down

Candace drives a total of 48 miles each day to get to work and back home. She works 5 days a week. Her car gets 21 miles per gallon of gas. About how many gallons does she need to drive to work and back home each week?

Answers

Answer:

11.43 gallons used exactly per week asuming not changes in schedule or any other reasons to drive and that a one way trip is 24 miles.

Step-by-step explanation:

48 as total for two trips

five of these need to be done, so 240 miles a week assuming no other reason to drive

240 / 21 = 10 with remainder 30

so 11 and remainder 9

9/21 = nearly .43 gallons, which means as a minimum she shouldn't go below 11.5 and better yet 12 gallons.

Final answer:

Candace drives 240 miles each week (48 miles per day * 5 days). Given her car's fuel efficiency is 21 miles per gallon, she would therefore need approximately 11.43 gallons of gas (240 miles / 21 miles per gallon) for her weekly commute.

Explanation:

To answer the question of how many gallons of gas Candace needs to get to work and back home each week, you need to first know how many miles she is driving in total for that week.

First, let's find the total miles she drives weekly. We know she drives 48 miles each day to work and back home and she works 5 days a week. So, miles per week = 48 miles per day * 5 days per week = 240 miles per week.

Next, we know her car gets 21 miles per gallon of gas. To find the gallons required, we divide the weekly miles by the miles per gallon. So, Gallons used per week = 240 miles per week / 21 miles per gallon ≈ 11.43 gallons per week.

So, she needs approximately 11.43 gallons of gas to drive to work and back home each week.
