I don't know your teacher's name but I know the answer to the other question.

Each additional mile will take a longer time of 2 minutes. Because the miles increase, the time would increase. If you think about it and you work as a pizza deliverer, the time should increase if the number of miles also increases. It's not magic.

Answer:

If a triangular prism and a cylinder have the same height and the same volume, then the area of bases must be equal.

=> Option A is correct

Step-by-step explanation:

Because they share the same formula to calculate V = Base area x Height

V and Height are same, then Base areas are same.

Hope this helps!

:)

If a triangular prism and a cylinder have the same height and the same volume, then their bases have the same area is true statement.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

If a triangular prism and a cylinder have the same height and the same volume, then their bases must have the same area.

This can be explained using the formula for the volume of a prism, which is equal to the area of the base times the height.

Since the height of both shapes is the same, the volume of the shapes is proportional to the area of their bases.

If the volume is the same for both shapes, then their bases must have the same area.

Therefore, their bases have the same area is the true statement among the given statements.

Answer:

5 Inches.

Step-by-step explanation:

Given the volume of a sphere[tex]=\dfrac{500\pi}{3} $ cubic inches[/tex]

We want to determine the radius of the sphere.

Volume of a Sphere [tex]=\dfrac{4\pi r^3}{3}[/tex]

Therefore:

[tex]\dfrac{4\pi r^3}{3}=\dfrac{500\pi}{3} \\$Multiply both sides by$ \dfrac{3}{\pi} \\4 r^3=500\\$Divide both sides by 4\\r^3=125\\r^3=5^3\\r=5$ inches[/tex]

The radius of the sphere is 5 Inches.

Answer:

Step-by-step explanation:

The given table is

Days     Bees

  0        10,000

 10        7,500

 20       5,600

 30       4,200

 40       3,200

 50       2,400

Where [tex]x[/tex] represents days and [tex]y[/tex] represents bees.

The exponential function that models this problem must be like

[tex]y=a(1-r)^{x}[/tex], which represenst an exponential decary, because in this case, the number of bees decays.

We nned to use one points, to find the rate of decay. We know that [tex]a=10,000[/tex], because it starts with 10,000 bees.

Let's use the points (10, 7500)

[tex]y=a(1-r)^{x}\\7500=10000(1-r)^{10}[/tex]

Solving for [tex]r[/tex], we have

[tex]\frac{7500}{10000}=(1-r)^{10} \\(1-r)^{10} =0.75[/tex]

Using logarithms, we have

[tex]ln((1-r)^{10}) =ln(0.75)\\10 \times ln(1-r)=ln(0.75)\\ln(1-r)=\frac{ln(0.75)}{10} \approx -0.03\\e^{ln(1-r)}=e^{-0.03}\\1-r =e^{-0.03}\\r=-e^{-0.03}+1 \approx 1.97[/tex]

Replacing all values in the model, we have

[tex]y=10000(1-1.97)^{x}\\y=10000(0.97)^{x}[/tex]

Therefore, the right answer is the first choice, that's the best approximation to this situation.

Answer:

Step-by-step explanation:

In a coordinate plane with point P( x , y) and Q(a,b ).

distance between these are points is given by equation

distance between PQ = [tex]\sqrt{(x-a)^2 + (y-b)^2}[/tex].

Coordinate of  subway stop = (7,3)

Coordinate of house = (4-5)

Therefore using the above the formula to calculate distance between

house and the subway stop is given by

distance = [tex]\sqrt{(7-4)^2 + (3-(-5)^2}\\\\=>\sqrt{(3)^2 + (3+5)^2}\\\\=>\sqrt{9 + (8)^2}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{73}\\\\=>8.544[/tex]

Therefore, distance between house and the subway stop is 8.544 units.

But it is given that distance should be to the nearest unit.

any decimal value greater than or equal to .5 is equivalent to 1 in nearest unit.

Thus, 8.544 units is equivalent to 9 units (in nearest unit)

Answer:

[tex]\frac{x^{2}}{400} + \frac{y^{2}}{976} = 1[/tex]

Step-by-step explanation:

The distance between foci with respect to origin is determined by mean of the Pythagorean Theorem:

[tex]2\cdot c = \sqrt{(0-0)^{2}+[24-(-24)]^{2}}[/tex]

[tex]2\cdot c = 48[/tex]

[tex]c = 24[/tex]

The distance between origin and any of the horizontal co-vertices is:

[tex]a = \sqrt{[10-(-10)]^{2}+(0-0)^{2}}[/tex]

[tex]a = 20[/tex]

Now, the distance between origin and any of the vertical co-vertices is determined by the following Pythagorean relationship:

[tex]c^{2} = b^{2} - a^{2}[/tex]

[tex]b^{2} = a^{2} + c^{2}[/tex]

[tex]b = \sqrt{a^{2}+c^{2}}[/tex]

[tex]b = \sqrt{20^{2}+ 24^{2}}[/tex]

[tex]b = 4\sqrt{61}[/tex]

Lastly, the equation of the ellipse in standard form is:

[tex]\frac{x^{2}}{400} + \frac{y^{2}}{976} = 1[/tex]

double chocolate chip=14

Step-by-step explanation:

c = chocolate chip

d = double chocolate chip

Brenda

6c+4d = 86

Jasmine

3c+ 5d = 85

Multiply the second equation by -2

-6c -10d = -170

Add this to the first equation

-6c -10d = -170

6c+4d = 86

--------------------

   - 6d = -84

Divide by -6

-6d /-6 = -84/-6

d =14

Now we can find c

3c+ 5d = 85

3c+5*14 = 85

3c +70 = 85

Subtract 70

3c = 85-70

3c = 15

Divide by 3

3c/3 = 15/3

c = 5

There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)

There's no solution to this particular system because the two lines are parallel.

How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.

The line on the left passes through the points (-1, 0) and (0, -2), so it has slope

(-2 - 0)/(0 - (-1)) = -2/1 = -2

The line on the right passes through (0, 2) and (1, 0), so its slope is

(0 - 2)/(1 - 0) = -2/1 = -2

The slopes are equal, so the lines are parallel.

Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.

Answer:

The number 10/7 is a rational number, which means it can be expressed as a fraction. Also, if we divide it would give a decimal infinite periodical number, which means it has a pattern on its decimal numbers.

On the other hand, the square root of 2 is irrational number, that means it can't be expressed as a fraction, because its decimal numbers don't have any pattern at all.

So, Mai's brother can see these type of numbers as crazy (irrational numbers) and sane (rational numbers).

At last, another important characteristic to shows that they aren't equal is that they don't have the exactly decimal numbers.

Answer:

$5,000

Step-by-step explanation:

First, you have to determine the total amount of money she needs to save to cover the cost of the tuition by subtracting the financial aid, the scholarship and the amount her parents plan to contribute from the total cost of the tuition:

40,000-(40,000/4)-(40,000*25%)-5,000

40,000-10,000-10,000-5,000

40,000-25,000= 15,000

She needs to save a total amount of 15,000. Then, you need to divide this amount by 3:

15,000/3= $5,000

Julieta will need to save $5,000 each year over the next 3 years before her first year.

Answer:y=2.5 x

Step-by-step explanation:

Given

Cow give 5 gallon of milk if it eats 2 pound of grass

i.e. it gives 2.5 gallon of milk if it eats 1 pound of grass

So we can say cow given 2.5 times of milk in gallon for each pound it eats

If cow eats x pounds of grass then it must yield 2.5 times of milk

Suppose milk is denoted by y  

therefore we can write

y=2.5 x

Therefore y=2.5 x represent the relation between grass and milk produced

Answer:

12/(7-4) + 5 * 3 = 19

Step-by-step explanation:

Given

Untrue Expression: 12 ( 7 − 4 ) + 5 3 = 19

Signs: +−×÷

Required

Use the given signs to make the equation true.

To solve this, the trial and error method will be adopted.

The trial and error method involves trying series of sign combinations in the given expression; whichever works is the right answer.

So, after few attempts the following makes the equation true

12/(7-4) + 5 * 3 = 19

To check if it's true or not; we simply expand the expression on the left hand side. This gives

12/3 + 5 * 3 = 19

4 + 5 * 3 = 19

4 + 15 = 19

19 = 19.

Hence, the sign combinations used in 12/(7-4) + 5 * 3 = 19 is correct.
