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:

speed of commuter bus: 32 km

speed of passenger car  : 48 mph

Step-by-step explanation:

We will use the concept of speed distance and time.

where time = distance / speed

____________________________________________________

Let the speed of commuter bus be x mph

Given that passenger car travels 16 mph faster than commuter bus.

Speed of passenger car if speed of commuter bus is x mph (x+16)mph

Distance traveled by commuter bus  = 56 miles

Time taken by commuter bus  to travel 56 miles = 56/X   (1)

Distance traveled by passenger car  = 84 miles

Time taken by passenger car to travel 84 miles = 84/(X+16)   (2)

__________________________________________

It is given that time taken by both bus and car is same

so equating equation  1 and 2

we have

56/X = 84/(X+16)   (by cross multiplication we have)

=> 56(X+16)  = 84*X

=> 56X + 896 = 84X

=> 896 = 84X - 56 X

=> 896 = 28X

=> X = 896/28 =  32.

Therefore , speed of commuter bus is x mph or 32 km

speed of passenger car  is x+16 mph = (32+16) mph = 48 mph

Final answer:

The passenger car travels at 48 mph, while the commuter bus travels at 32 mph, derived from the fact that they travel the same time but different distances.

Explanation:

To find the speeds of the passenger car and the commuter bus, we can use the formula for distance (distance = speed × time). Since both the bus and the car travel for the same amount of time, we can set up an equation to solve for their speeds based on the distances they travel.

Let x be the speed of the commuter bus in mph. Consequently, the speed of the passenger car would be x + 16 mph. According to the information given:

The bus travels 56 miles.

The car travels 84 miles.

Since they travel for the same time t, we have:

Bus: 56 miles = x × t

Car: 84 miles = (x + 16 mph) × t

Dividing the mileage of the car by the bus gives us:

[tex]\(\frac{84}{56} = \frac{(x + 16)t}{xt}\)[/tex]

[tex]\(1.5 = \frac{x + 16}{x}\)[/tex]

Multiplying by x to get rid of the fraction and then solving for x provides:

1.5x = x + 16

0.5x = 16

x = 32 mph

This means the bus travels at 32 mph and the passenger car travels at:

32 mph + 16 mph = 48 mph

Therefore, the speed of the passenger car is 48 mph and the speed of the commuter bus is 32 mph.

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:

The length of the arc is 221π/18 ft or 38.55 ft

Step-by-step explanation:

Given

Subtended angle, θ = 17π/18

Radius, r = 13 ft

Required

Length of the arc.

When an angle is given in radians, the length of the arc is calculated using the formula below

Length = rθ

By substituting

Length = 13 * 17π/18

Length = 221π/18

The answer can be left in this form.

But for simplification purpose, I'll solve further.

Taking π as 3.14

Length = 221 * 3.14/18

Length = 693.94/18

Length = 38.552222

Length = 38.55 ft (Approximated).

Hence, the length of the arc is 221π/18 ft or 38.55 ft

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.

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.
