For this case we have the following numerical value:
12.57 centimeters
We note that the number is rounded to the nearest hundredth.
If we want to round the number to the nearest decimal we must rewrite the number.
Rewriting we have:
12.6 centimeters

this value rounded to the nearest tenth of a centimeter is:

12.6 centimeters

An engineer is planning a new water pipe installation. The circular pipe has a diameter of d=20\text{ cm}d=20 cmd, equals, 20, space, c, m. What is the area AAA of the circular cross section of this pipe?
Solution 1

Step-by-step explanation:  Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.

We need to find the area 'A' of the circular cross-section of the pipe.

Given, diameter of the circular section is

So, the radius of the circular cross-section will be

Therefore, cross-sectional area of the pipe is

Thus, the answer is 314.28 cm² (approx.).

What is the product written in scientific notation? (2.1 x 10–2)(3.2 x 10–4) a. 6.72 x 108 b. 6.72 x 10–6 c. 5.3 x 102 d. 5.3 x 10–6
Solution 1
First, you multiply 2.1 by 3.2, which gives you the answer of 6.72. Then, you multiply 10-2 by 10-4. One rule about multiplying exponents, you just add the exponents. So 10-2 x 10-4 = 10-6. Finally you get the answer of C. 6.72 x 10-6.
Question
The combined cost of one advance ticket and one same-day ticket to a show was $50. it is known that 17 advance tickets were sold and 48 same-day tickets were sold, for total receipts of$1842. what was the price of each kind of ticket?
Solution 1
1 advance + 1 same-day = $50 17 advance + 17 same-day =$50 x 17 = $850$1842 - $850 =$992
48 - 17 = 31 same-day

31 same-day = $992 1 same-day =$32

1 advance + 1 same-day = $50 1 advance +$32 = $50 1 advance =$50 - $32 =$18

Answer: same day ticket costs $32 and advance-day ticket costs$18.

Solution 2
A same day ticket costs $32 and an advance day ticket costs$18. Hope this helpd.

Question
A line of best fit predicts that when x equals 35, y will equal 34.785, but actually equals 37. What is the residual in this case?
Solution 1
We know that

Residual Value = Observed Value– Predicted Value

in this problem
Observed Value=37
Predicted Value=34.785
Residual Value = 37-34.785------> 2.215
positive values for the residual (on the y-axis) mean that the prediction was too low

2.215
Question
What is the equation of the axis of symmetry of the graph of y + 3x – 6 = –3(x – 2)squared + 4?
Solution 1

x = 3/2

Step-by-step explanation:

That is quite long and drawn out, so we have to get it down to a single quadratic equation, set equal to 0.

Begin by expanding the right side to get

then multiplying in the -3 to get

Now we will combine all the like terms and get everything on one side of the equals sign, and set it equal to 0:

In order to find the equation of the axis of symmetry we have to put it into vertex form, which is accomplished by completing the square on this quadratic.

In order to complete the square, the leading coefficient has to be a +1.  Ours is a -3, so we will factor that out.  First, though, now that it is set to equal 0, we will move the constant, -2, over to the other side, isolating the x terms.

Now we can factor out the -3:

The rules for completing the square are as follows:

Take half the linear term, square it, and add it to both sides.  Our linear term is 3.  Half of 3 is 3/2, and squaring that gives you 9/4.  We add into the parenthesis on the left a 9/4, but don't forget about that -3 hanging around out front that refuses to be ignored.  We didn't add in just a 9/4, we added in (-3)(9/4) = -27/4:

In the process of completing the square we created a perfect square binomial on the left.  Stating that binomial and simplifying the addition on the right gives us:

We can determine the axis of symmetry at this point.  Because this is a positive x-squared polynomial, the axis of symmetry is in the form of (x = ) and what it equals is the h coordinate of the vertex.  Our h coordinate is 3/2; therefore, the axis of symmetry has the equation x = 3/2

Question
How many radii does a circle have? Explain.
Solution 1
Radii is defined as the line joining the centre of the circle to a point on the circumference
as there are infinite points on a circle
therefore there are infinite number of radii and hence there is no fixed number.

Question
Multiply 12.57 by 4.11. Round your answer to the nearest hundredth. a. 51.25 b. 51.66 c. 49.45 d. 52.66
Solution 1
When you are going to multiply 12.57 by 4.11, the result would be 51.6627.

To round off the result to the nearest hundredth, it would become 51.66.

According to the rules of rounding off a number, if the number after the rounded off digit is more than or equal to 5, you have to add 1 to the rounded off digit. But if it is less than 5, then the rounded off digit would be still the same. In this case, the rounded off digit which is 6 would still be the same since the number after that is 2 which is less than 5.
So, the answer is letter B which is 51.66
