A 20-inch bicycle has tires with a diameter of 20 inches. What is the circumference of these tires?
31.4 inches
62.8 inches
314 inches
1256 inches
Answer:B
Step-by-step explanation:
c=2nr or c=nd
2*3.14 * 10= 62.8
3.14 * 20= 62.8
The circumference of the tires is 62.8 inches.
What is Circumference?Circumference of a circle is defined for non straight curves which is the length of the boundary of the curve.
Given that, a 20-inch bicycle has tires with a diameter of 20 inches.
Diameter of the tire = 20 inches.
Radius of a circle or a circular object is half of the diameter of it.
Radius of the tire = 20 / 2 = 10 inches
Circumference of a circular object = 2πr, r is the radius.
Circumference of the tire = 2π r
= 2 (3.14) (10)
= 62.8 inches
Hence the circumference of a bicycle tire is 62.8 inches.

Below is the graph of equation y=− |x−2| +2. Use this graph to find all values of x such that y>0
Answer:
Value of y > 0 at [tex]x = \{0, 1, 2, 3, 4\}[/tex]
Step-by-step explanation:
As seen from the graph attached in answer area as well, The graph is above x-axis (i.e. y value of equation) only when x has values {0, 1, 2, 3, 4}.
At x = 0:
[tex]y = -|0-2| + 2 \\\Rightarrow -2 + 2\\ \Rightarrow y = 0[/tex]
At x = 1:
[tex]y = -|0-1| + 2 \\\Rightarrow -1 + 2\\ \Rightarrow y = 1[/tex]
At x = 2:
[tex]y = -|2-2| + 2 \\\Rightarrow 0 + 2\\ \Rightarrow y = 2[/tex]
At x = 3:
[tex]y = -|3-2| + 2 \\\Rightarrow -1 + 2\\ \Rightarrow y = 1[/tex]
At x = 4:
[tex]y = -|4-2| + 2 \\\Rightarrow -2 + 2\\ \Rightarrow y = 0[/tex]

A jeweler sells gems at a cost in dollars per centigram that is 4 more than 6 times the weight of the gem in centigrams.
Thus, a gem that weighs w centigrams will be sold at a price of 6w + 4 dollars per centigram - meaning that a larger,
heavier gem will cost more per centigram than a smaller gem. If the jeweler sold a single gem for about $2500, what
did the gem weigh to the nearest centigram?
Answer:
416 centigrams
Step-by-step explanation:
2500 = 6w + 4
2496 = 6w
416 = w

help please find the volume
Answer:
[tex]312 inches^{2}[/tex]
Step-by-step explanation:
The formula to work out the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
to find the volume of this shape you would first need to work out the area of the triangle. You can do this by first multiplying the base of 6 by the height of 8, this gives you 48. The next step in working out the area is to divide 48 by 2, this gives you 24. This is because by multiplying the base by the height you are working out the area of a square with the same dimensions, and so will need to be divided by 2 to work out the area of the triangle. Now that you have worked out the area you can now work out the volume. To do this you would simply multiply the area of 24 by the height of 13, this gives you 312.
Working out the area:
1) Multiply 6 by 8.
[tex]6*8=48[/tex]
2) Divide 48 by 2.
[tex]48/2=24[/tex]
Working out the volume:
1) Multiply 24 by 13.
[tex]24*13=312 inches^{2}[/tex]

coordinates of the other point?
A (2, 2)
B (2, 3)
C (2, –3)
D (–2, –3)
Answer:
D (-2, -3)
Step-by-step explanation: The distance is 10 units, so you take -4 (x) and go over 2 spaces so your at x = -2, and 2 units are down, 8 more to go. Then for (y) you do 5-8 and get -3 so now y = -3 . Now you have moved 10 spaces because 2 + 8 = 10 spaces, and are left at D (-2, -3).

The function whose graph is given is y = 0.5cosx
What is a function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given that, a graph we need to find its function,
To analyze the given graph let us,
compare the given to a known, standard functiontake maxima and minima points from the graph and analyze them.From the given graph we can pick the points which can tell us about the nature of the cosine function we took,
It is clear from the graph that the function plotted is equal to the standard function i.e. cos(x)
in cos(x) ⇒ we have minima at (-π, 1)
in the given graph, the function has a maximum and touches the y-axis at (0, 0.5)
Therefore, 0.5cosx is the function represented in the graph.

The area of a circle is given by A = πr^2 , where π = 3.14 and r is the radius of the circle. Determine the area of a circle with radius 14.2 cm. Round your answer to the nearest tenth.
Answer:
The area of the circle is 1988.1 cm.
Step-by-step explanation:
You basically have all of the instructions on how to do this in the question.
Multiply 3.14 by the radius. 3.14 x 14.2 = 44.588Now you just have to square it. 44.588^2 = 1988.0897.And lastly we have to just round it to the nearest tenth. Rounded = 1988.1.I hope I helped.
