Answer: $7,81; $4.78 per mile

Step-by-step explanation:

To get the cost per mile we have to divide 9,500 by the cost.

(The total cost annual was $3,200)

9,500 divided by $1,215 = $7.81

9,500 divided by $1,985 = $4.78

Answer:

Mr. Prieto can buy 6 pizzas

Step-by-step explanation:

Cost of 5 soda's = 5 * 2  = $ 10

Remaining amount with him after buying 5 soda's= 94 - 10 = $ 84

Number of pizza's = Remaining amount/cost of 1 pizza

[tex]=\frac{84}{14}[/tex]

=  6 pizzas

Answer:

he can buy 6 pizzas

Step-by-step explanation:

5 x 2 = 10

94-10 = 84

84 divided by 14 = 6

he can buy 6 pizzas.

Answer:  Armando used the wrong dimensions for the triangular prism.

Step-by-step explanation:

Hi, to answer this question we have to analyze Armando’s work.

Total Volume = Volume of rectangular prism + volume of triangular prism  

Total Volume = 5 (8) (18) + one-half (6) (18) (8)  

Total Volume= 720 + 432  

Total volume = 1,152 cubic inches.

He made a mistake in the second step, where used h=8 for the triangular prism instead of h= 5 . (h=height)

The correct way to solve this is.

Total Volume = 5 (8) (18) + one-half (6) (18) (5)  

Total Volume= 720 + 270

Total volume = 990 cubic inches.

Answer:

Step-by-step explanation:

Answer:

15..

Step-by-step explanation:

4, 10, 14, 18, 22, 22

Mean = (4 + 10 + 14 + 18 + 22 + 22)/6

= 90/6

= 15.

Number to be added, 'y'

For the mean to be the same

(90 + y) / 7 = 15

90 + y = 15 × 7

90 + y = 105

y = 105 - 90

= 15

Answer:

Step-by-step explanation:

The total surface area of the triangular prism will be 14 square centimeter.

Option C is correct.

Total surface area :

From the  given diagram of  triangular prism,

It is observed that, The total surface area of the triangular prism will be the summation of area of two triangle and area of large rectangle.

Area of one triangle =(1/2)*3*2 = 3  square centimeters

So that, area of both triangle =2 * 3=6 square centimeters

Area of large rectangle=(2.5+3+2.5)*1=8*1=8 square centimeters

total surface area of the triangular prism =8+6=14 square centimeters

Therefore, total surface area of the triangular prism is 14 square centimeters.

The value of x of the missing angles is: 45

How to find the missing angle?

A linear pair of angles is a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair are always supplementary, which means their measures add up to 180 degrees.

Some properties of linear pairs of angles include:

The angles in a linear pair are adjacent.

Their non-common arms are opposite rays and form a straight line.

They together form a straight angle.

Two angles forming a linear pair have a common vertex and a common arm. Their non-common sides are opposite rays that form a line.

Thus:

Answer:

the model for the height, h, of the chair at a function of time is [tex]y = -20 \times sin (\frac{2\pi }{15} \times t + \frac{\pi }{2} ) + 26[/tex]

Step-by-step explanation:

To answer the question, we note that the height of the Ferris will varies proportionately to the angle of rotation, hence we can model the height according to he sine function as follows;

y = a·sin(b·x+c) + d

Where: a = Amplitude = Maximum displacement = r = 20 ft

or [tex]a = \frac{maximum - minimum}{2} = \frac{44 - 4}{2} = 20 \, ft[/tex]

The period,  [tex]\frac{2\pi }{b}[/tex] = Time for one complete revolution, for a Ferris wheel making 4 revolutions per minute, we have

Period = 1 minute/4 = 15 seconds

Therefore,  [tex]\frac{2\pi }{b}[/tex] = 15 seconds or [tex](b =\frac{2\pi }{15})[/tex]

d = the vertical shift is given by minimum + amplitude or maximum - amplitude = 6 + 20 = 26 ft

c = Phase shift since we want the chair to be at the minimum at t = 0 we put c = π/2

x = Independent variable, which in the case of the question is time, t

Therefore, the model for the height, h, of the chair at a function of time is as follows

[tex]y = -20 \times sin (\frac{2\pi }{15} \times t + \frac{\pi }{2} ) + 26[/tex]

i.e. y = -20×sin(2π/15 + π/2) + 26.

Final answer:

To model the height of the chair as a function of time on a Ferris wheel, use the equation h(t) = 20 × cos((8π/60)t) + 6, where t is in seconds and h(t) is in feet.

Explanation:

To write a model for the height, h, of the chair as a function of time, t, for a Ferris wheel with a radius of 20 feet and a rotation rate of 4 revolutions per minute, we must consider the motion of the wheel. Since the Ferris wheel completes one rotation in 15 seconds (60 seconds/4 minutes), the chair's height above the ground will depend on the cosine of the angular position of the chair. Including the initial condition of the chair being 6 feet above the ground at its lowest point, the mathematical model will be:

h(t) = 20 × cos(ωt + ϕ) + 6

where angular velocity ω is calculated from the rotation rate (4 revolutions per minute) and phase shift ϕ accounts for the initial position. Since t = 0 corresponds to the lowest point, ϕ is 0 degrees or 0 radians (cos(0) = 1). The angular velocity in radians per second is:

ω = 2π × rotation rate = 2π × 4 / 60 = 8π/60 rad/s

Thus, the final equation for the height of the chair as a function of time is:

h(t) = 20 × cos((8π/60)t) + 6

where t is in seconds and h(t) is in feet.

Step-by-step explanation:

The minimum length of a table that is 3 feet wide to have at least 24 square feet of space is found by solving the inequality 3L ≥ 24, which results in a minimum length of 8 feet.

The question involves finding the minimum length of a table to achieve a certain area, which requires understanding and solving an inequality. Given that the table is 3 feet wide and we need at least 24 square feet of space, we can set up the inequality as follows:

Let L be the length of the table in feet.

The area A of a rectangle is calculated as A = length × width.

Thus, A = L × 3 square feet.

To satisfy the condition of having at least 24 square feet, we have the inequality 3L ≥ 24.

Dividing both sides by 3 to solve for L, we get L ≥ 8.

Therefore, the minimum length the table should have is 8 feet.

4x + y = 3

In the picture attached, the solution set is shown.

The first equation goes through (0, 3) and (2, 4), as can be checked by:

–(2) + 2(4) = 6

The second goes through (0, 3) and (0.75, 0), as can be checked by:

4(0) + (3) = 3

4(0.75) + (0) = 3

On a coordinate plane, a line goes through (-6, 0) and (0, 3) and another line goes through (0.75, 0) and (0, 3).

Given :

Step 1 - Write the given system of equations.

-x + 2y = 6        --- (1)

4x + y = 3         --- (2)

Step 2 - The x-intercept of equation (1) is:

-x + 0 = 6

x = -6

Step 3 - The y-intercept of equation (1) is:

0 + 2y = 6

y = 3

Step 4 - The x-intercept of equation (2) is:

4x + 0 = 3

x = 3/4

Step 5 - The y-intercept of equation (2) is:

0 + y = 3

y = 3

Answer

12 (5 - 3)

Step-by-step explanation:

The greatest common factor is the largest number that will divide both numbers evenly. As an example, 6 is a common factor because it divides both 60 and 36. However, it is not the greatest common factor.

If I break 60 into it's prime factors, I would get 2 * 2 * 3 * 5.

If I break 36 into it's prime factors, I would get 2 * 2 * 3 * 3.

The two number have the factors, 2, 2, and 3 in common.

The greatest common factor is then: 2 * 2 * 3, or 12.

The expression can be factored as:  12 ( 5 - 3)

To factor the expression 60 - 36, we need to find the GCF of the numbers. The GCF is 12, so the factored form is 24.

To factor the expression using the Greatest Common Factor (GCF) 60 - 36, we need to find the largest number that evenly divides both 60 and 36. The GCF of 60 and 36 is 12.

Therefore, we can rewrite the expression as 12 * (5 - 3). Simplifying further, we get 12 * 2 = 24.

So, the factored form of 60 - 36 is 24.

Answer:

A) ∠D ≅ ∠F

Step-by-step explanation:

Supplementary angles : A pair of angles whose sum is 180° are called supplementary angles

We are given that ∠D is a supplementary angle of ∠E

We are also given that ∠F is a supplementary angle of ∠E

So,[tex]\angle F+\angle E = 180^{\circ} ------2[/tex]

Find the value of ∠E form 1 and 2

From 1 : [tex]\angle E = 180^{\circ}-\angle D[/tex]

From 2 : [tex]\angle E = 180^{\circ}-\angle F[/tex]

So, [tex]180^{\circ}-\angle D=180^{\circ}-\angle F[/tex]

[tex]\angle D=\angle F[/tex]
