Answer:

Step-by-step explanation:

Let d be the diameter of the wheel.

Circumference = πd

(35.325 m)/(25 revolutions) = (1.413 m)/revolution

πd = 1.413

d = 1.413/π = 0.45 m

Answer:

V= 120 in cubed.

QUESTION:

How do we show that two lines are parallel when using slope? How do we show they are perpendicular when using slope?

ANSWER:

How to determine if a line is a parallel perpendicular or neither?

The slopes of parallel lines are equal, and the slopes of perpendicular lines are opposite reciprocals. This is a worked example of determining whether given lines are parallel or perpendicular.

Answer:

Ernie is incorrect.

Step-by-step explanation:

I suppose that we want to see if Ernie statement is correct or not.

Suppose that we have a line that passes through the points (x₁, y₁) and (x₂, y₂)

The slope of that line can be calculated as:

slope = (y₂ - y₁)/(x₂ - x₁)

In this case, we know that the line passes through (0, 0) and (3, 3), then the slope of this line is:

slope = (3 - 0)/(3 - 0) = 3/3 = 1

Then Ernie got the slope wrong, which means that he is wrong.

Answer:length of the other piece=39.86m

Step-by-step explanation:

Total length of rope =63.45 m

length of one piece = 23.59 m

Since the rope was cut into two pieces, we subtract the length of  known first piece from the total length

length of the other piece  = 63.45 m-23.59 m=39.86m

Answer:

y = 3x

Step-by-step explanation:

to get y we multiply x by 3 so we have that y = 3x.

Answer:

(3z+15) cm

Step-by-step explanation:

Perimeter: z cm + 8 cm + (z+3) cm + (z+4) cm = z cm + (z+3) cm + (z+4) cm +8 cm = (3z + 7) cm + 8 cm = (3z+15) cm.

Answer:

the mean is 6

the median is 6

the mode there is none

the range is 6.

Answer:

There is no mode. (they all appear once)

The lowest number is 3 and the highest is 9, so the range is 6.

The mean is the average, add them all up (30) and divide by the number of data sets (5). The average is 6.

I have to go to dinner so maybe let someone else help with the median? The median is the middle, so you have to order them and find the middle. Hope it helped!

Answer:

Yes it is a function.

Step-by-step explanation:

It is given that James raises chickens in his farm. and the chicken laid eggs on each day. James keeps a track of the number of eggs that his chicken laid at the end of each week.

This is a function because according to the definition of a function, if each of he input corresponds to exactly one output, then that relation is called as a function.

In this case, every week the chickens lay different number of eggs. So every week corresponds to the different number of eggs laid by the chicken. So it is a function.

Answer:

Yes it is a function because there is a domain/Input for each Range/Output

Answer:

Similarities: both have a base which extends into a single vertex.

Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).

the base of a pyramid is a polygon - the base of a cone is a curve

(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).

Step-by-step explanation:

The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.

Pyramids and cones are alike in the following ways:

Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.

The formula for the area of a right angle triangle is:

A =   hb/2

The area of a cone is given as:

A = [tex]\pi[/tex] r (r + [tex]\sqrt{(h²+r²)}[/tex]
