Scenario:
A stack of n small cups has a height, h, in centimeters of h=1.5n+6.
A stack of n large cups has a height, h, in centimeters of h=1.5n+9.

Using G00gle Draw, or by hand, graph the equations for each cup on the same set of axes. Make sure to label the axes and decide on an appropriate scale.

For what number of cups will the two stacks have the same height?

Answers

Answer:

The lines will never intersect.

Step-by-step explanation:

The slope of the cups is the same, 1.5.  The y-intercept of the small cups is 6

The y-intercept of the big cups is 9.

This means that the lines will never intersect because they are parallel lines and have the same slope but different y-intercepts.

Answer:

d = 12 miles

Step-by-step explanation:

From the given information, we know that t is for time in minutes. In the question, we were given a value of 30 minutes. We just need to substitute the variable t for the number 30. This will make the equation d = .4*30

This will result in the answer: d = 12

Which of the following formulas could be used to determine the volume of a cone stacked on top of half a sphere?
Select all that apply.

V = lwh
V = Bh
V = 1/3 Bh
V = pi* r^2h
V = 1/3 pi* r^2h
V = 4/3 pi* r^3

Answers

Answer:

I think it is V=pi* r^2h and V = 4/3 pi* r^3 but I am not 100% sure.

Step-by-step explanation:

The correct options are 5 (1/3 pi* r^2h) and 6 (4/3 pi* r^3).

What is Volume?

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere. Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry.

As per the given data:

The formula for volume of various figure is given.

We have to find the formulas which can be used to determine the volume of a cone stacked on top of half a sphere.

Volume of a cone stacked on top of half a sphere:

= Volume of a hemisphere + Volume of a cone

= (Volume of a sphere/2) + Volume of a cone

Volume of a sphere = 4/3 pi* r^3

Volume of a cone = V = 1/3 pi* r^2h

Hence, the correct options are 5 (1/3 pi* r^2h) and 6 (4/3 pi* r^3).

Is college math a lot of triangles? ( please answer)

Answers

Answer:A triangle is a three-sided figure whose angles always add up to 180°. Thus, ∠x +∠y + ∠z = 180°.

The largest angle of a triangle is opposite its longest side.

On the SAT, the triangle to the left would be referred to as triangle abc or ∆abc.

To find the perimeter of the triangle, add up all the sides (a + b + c).

To find the area of any triangle, use the formula, (1⁄2)bh. The height must be perpendicular to the base.

Two triangles are similar if their angles have the same measure. The triangles therefore have the same shape, and their sides will be in proportion.

Triangles are said to be congruent if they have the same shape and size.

Equilateral Triangles

Equilateral Triangle

An equilateral triangle has three equal sides. Thus: a = b = c.

An equilateral triangle has three angles are also equal. Thus, ∠x = ∠y = ∠z.

Since the angles of a triangle always add up to 180°, each angle of an equilateral triangle must also equal 60°. Thus, ∠x = ∠y = ∠z = 60°.

How do you convert 14x + 19y = 20 into slope intercept form?

Answers

Subtract 14x from both sides. Then divide both sides by 19

[tex]14x + 19y = 20\\\\19y = 20-14x\\\\19y = -14x+20\\\\y = \frac{-14x+20}{19}\\\\y = \frac{-14x}{19}+\frac{20}{19}\\\\y = -\frac{14}{19}x+\frac{20}{19}\\\\[/tex]

The equation is now in slope intercept form y = mx+b

m = -14/19 is the slope

b = 20/19 is the y intercept

Alicia reserves buses for a field trip. Each bus holds 36 people. There are 127 people signed up for the field trip so far. How many more people can sign up before Alicia needs to reserve another bus?​

Answers

Answer:

20!

Step-by-step explanation:

As per the given data, Alicia can accommodate 17 more people without reserving another bus.

What is field trip?

A field trip is a type of educational excursion that is usually organized by schools, colleges, or other educational institutions.

Alicia has already reserved 3 buses since 3 x 36 = 108 people can fit on those buses.

There are 127 - 108 = 19 people who have not been accounted for on those buses.

Since each bus holds 36 people and there are 19 people who still need to be accounted for, Alicia can still add 36 - 19 = 17 more people before she needs to reserve another bus.

Therefore, Alicia can still sign up 17 more people before needing to reserve another bus.

Answers

Answer:

13*f

Step-by-step explanation:

20*f + 6*f ÷ 2 = 13*f

hope it helps please like


Answers: 2x - 6 = 20 & x = 13

Explanation: The x in this equation is the temperature 5 hours ago. In the word problem, 20 degrees is the x temperature multiplied by 2 (since it says “twice the temperature”) and subtracted by 6 (since it says “6 degrees less). Therefore, the equation would be the x changing (due to the multiplying of 2 and subtraction of 6) that equal 20. When solving, first check to see if there are any like terms (None in this problem). Next, isolate the variable. Here, you add the opposite of 6 to both sides (-6 + 6 and 20 + 20). This makes it 2x = 26. Now divide by the coefficient (2x / 2 and 26 / 2). This will be x = 13.
