Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?


if h=3, then r=


if r=2, then h=

Answers

Answer: r = 1.69 inches

              h = 2.15 inches

Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.

Volume of a cone is directly proportional to radius and height:

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

They want the cones to hold the same volume of 9 cubic inches.

If height is 3:

[tex]9=\frac{1}{3}\pi r^{2}3[/tex]

[tex]\pi r^{2}=9[/tex]

[tex]r^{2}=2.864[/tex]

r = 1.69 inches

When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.

If radius is 2:

[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]

[tex]h=\frac{9(3)}{4 \pi}[/tex]

h = 2.15 inches

If radius is 2 inches, height of the cone is 2.15 inches.

A scuba diver descends 80 feet, rises 25 feet, descends 12 feet, and then rises 52 feet where he will do a safety stop for five minutes before surfacing. At what depth did he do his safety stop?

Answers

Answer:

15 ft

Step-by-step explanation:

At 15 feet below the surface, the scuba diver did his safety stop.

What is the surface?

The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.

Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.

∴ [ - 80 + 25 + (-12) + 52 ] feet.

= (-80 + 25 - 12 + 52) feet.

= - 15 feet.

So, at 15 feet below the surface the scuba diver dis his safety stop.

Answers

Answer:

D I dont know if im right though

Step-by-step explanation:

The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The first equation is -3x + 3y = 12  be equation (1)  

y = x + 4   be equation (2)

Adding 3x on both sides , we get

3y = 3x + 12

Divide by 3 on both sides , we get

y = x + 4   be equation (3)

So , the equation ( 2 ) is same as equation ( 3 )

Now , the slope of the equation is m = 1 and the y intercept is b = 4

Hence , the equations have infinite solutions

Answers

m∠LKM = 26.1°

Ffkdkdkkddkd

The measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

The point where two lines meet or intersect is known as an angle.

If L is in the interior of ∠JKM, then:

∠JKL + ∠LKM = ∠JKM

Given the following parameters

m∠JKL=56.4° and m∠JKM=82.5°

Required angle

m∠LKM

From the expression above:

m∠LKM = ∠JKM - ∠JKL

m∠LKM = 82.5 - 56.4

m∠LKM  = 26.1 degrees

Hence the measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

Benefits to jack of his active participation in decisions relating to health and well being(6 mark question also jack is 49) You are a financial advisor helping a young family create a college fund to provide for their daughter Marys education. Mary just turned 5. Her parents expect that she will go to Harvard University, starting school on her 18th birthday. She will only take four years to complete her degree. Currently, tuition and housing costs total $65,000 per year, which are paid at the beginning of each school year. These expenses are expected to increase at the rate of inflation which will run 4% annually for the next 25 years. In each year until Mary enters Harvard University, Marys parents will make a deposit into the college fund to exactly provide for all of the costs of her education when she enters college (the first deposit will be made one year from today). Since her parents expect their income to grow at the rate of 2% annually, they would like the amount that they put each year into the fund to increase in nominal terms at the rate of 2% annually. Marys parents can earn a rate of 10% annually on their investments and they face a 30% tax rate. A. What do you expect tuition and housing to cost during Marys first year at Harvard University?B. How much must be in the savings account on Marys 18th birthday after the last deposit has been made but before the first payment to Harvard University?C. What should be the amount of the first payment?D. Alternatively, Marys parents could open a 529 account that allows college savings to grow tax-free. If they saved in this account rather than in a normal investment fund, and still earned the same pre-tax return, how much should be their first deposit?
