5.)which of the following is the best example of pair of lines that are parallel?
A. con consecutive sides of a window
B. intersection intersection of roadways
C. really really railway lines crossing
D. two two opposite edges of a door
Answer:
D
Step-by-step explanation:
D because it is the only choice that obtains things that do not intersect or cross each other at some point. The doors would never cross, unlike the windows or roadways or railways.
So option D would be the best answer.

2970
Step-by-step explanation:
I hope it helped :) if it didnt just message me since in confused whats the dot between the 6.3 and 10²
Answer:
2.97*10^3
Step-by-step explanation:
You have to solve it first so you have 2970 as your answer but you want it in scientific notation. To do this put the decimal after the first number this gives you 2.970. Whenever you need to make the number bigger you use a positive power and whenever you want to make a number smaller you use a negative power. The amount of powers the 10 gets is the amount of times you move it over. You have 2.970 and to get to the original number you need to move it 3 places to the right. Going to the right with your decimal makes it bigger which what you want, so you have 2.970*10^3 as your answer.

25 The library has an empty bookcase with 4 shelves. Each shelf can hold 23 chapter þooks. If the library has 117 new chapter books, how many will not fit on the bookcase?.
Answer:
25 chapter books
Step-by-step explanation:
117 - (23×4)
[23×4=92]
.°. 117 - 92 = 25
Step-by-step explanation:
Total Shelf Capacity = Capacity per shelf x Number of Shelves
= 23 x 4
= 92
Number of new books to be fit in = 117
Amount of books Overflow = Number of books to be fit in - Total Shelf Capacity
= 117 - 92
= 25

Janelle invests in a piece of art that cost 600 British Pounds. A study found that art appreciates in value at a rate of 3.97% per year. Assuming this pattern continues, how much, in British Pounds, will Janelle's piece of art be valued at after 10 years? Round your answer to the hundredths place.
Enter your answer in the box.
British Pounds
Answer:
It will be worth about £885.59.
Step-by-step explanation:
The art piece originally costs £600.
And it appreciates at a rate of 3.97% each year.
And we want to find the value of the art after 10 years.
We can write an exponential function to model the situation. The standard exponential function is given by:
[tex]f(t)=a(r)^t[/tex]
Where t is the time in years.
Since it appreciates at a rate of 3.97% each year, the value after each year will be (100% + 3.97%) or 103.97%.
103.97% = 1.0397. So, r = 1.0397:
[tex]f(t)=a(1.0397)^t[/tex]
Our a is the initial value. Therefore:
[tex]f(t)=600(1.0397)^t[/tex]
Then the value of the piece of art after 10 years is:
[tex]f(t)=600(1.0397)^{10}=885.5879...\approx \pounds 885.59[/tex]
It will be worth about £885.59 after 10 years.
Answer:
885.59
Step-by-step explanation:
1. 600 + 23.82
2. 623.82 + 24.77
3. 648.59 +25.75
4. 674.34 + 26.77
5. 701.11 + 27.83
6. 728.94 + 28.94
7. 757.88 + 30.09
8. 787.97 + 31.28
9. 819.25 + 32.52
10. 851.77 + 33.82
After 10 years the art valued for 885.59 British Pounds.

A Florida juice company completes the preparation of its products by sterilizing, filling, and labeling bottles. Each case of orange juice requires 9 minutes for sterilizing, 6 minutes for filling, and 1 minute for labeling. Each case of grapefruit requires 4 minutes for filling, 10 minutes for sterilizing, and 2 minutes for labeling. Each case of tomato juice requires 1 minute for labeling, 4 minutes for filling, and 12 minutes for sterilizing. The company runs the sterilizing machine for 398 minutes, the filling machine for 164 minutes, and the labeling machine for 58 minutes, how many cases of each type of juice are prepared?
1. Carefully identify your variables and write the equations that need to be solved.
2. Solve the system by the Gauss-Jordan elimination method.
Answer:
1.
R= Number of orange juice cases.
G = Number of greapefruit juice cases.
T = Number of tomato juice cases.
Equations:
9R+10G+12T=398
6R+4G+4T=164
R+2G+T=58
2.
R=6
G=20
T=12
Step-by-step explanation:
1.
The problem is talking about three types of products and it wants us to find how many of each the factory prepares. Since this is the data we need to know, then we set them to be our variables:
R= Number of orange juice cases.
G = Number of greapefruit juice cases.
T = Number of tomato juice cases.
Next, we can use the provided information to build our equations. First, we start with the Sterilizing machine equation: 9 minutes for orange juice, 10 minutes for grape juice and 12 minutes for tomato juice. So we use the sterilizing values for each of the product, to build our first equation:
9R+10G+12T=398
next, we build the filling machine equation, so like on the previous equation, we use the provided data for filling to build the second equation:
6R+4G+4T=164
and finally we build the labeling machine equation so we get:
R+2G+T=58
so we need to solve the following system of equations:
9R+10G+12T=398
6R+4G+4T=164
R+2G+T=58
2.
The very first thing we need to do in order to solve this problem by using the Gauss-Jordan elimination method is to build our matrix based on the system of equations we got on the previous part.
[tex]\left[\begin{array}{cccc}9&10&12&398\\6&4&4&164\\1&2&1&58\\\end{array}\right][/tex]
The idea is to end up with an identity matrix on the first three columns, that will directly give us the answer to the system of equations. So we can start by dividing the first row into 9: [tex]\frac{R_{1}}{9}[/tex] So we get:
[tex]\left[\begin{array}{cccc}1&\frac{10}{9}&\frac{4}{3}&\frac{398}{9}\\6&4&4&164\\1&2&1&58\\\end{array}\right][/tex]
Next, we can multiply the first row by -6 and add it to the second row to get the new second row. [tex]-6R_{1}+R_{2}[/tex]
so we get:
-6 -20/3 -8 -796/3
6 4 4 164
---------------------------------
0 -8/3 -4 -304/3
our matrix now looks like this:
[tex]\left[\begin{array}{cccc}1&\frac{10}{9}&\frac{4}{3}&\frac{398}{9}\\0&-\frac{8}{3}&-4&-\frac{304}{3}\\1&2&1&58\\\end{array}\right][/tex]
Next, we can subtract R3 from R1 so we get:
1 10/9 4/3 398/9
-1 -2 -1 -58
------------------------------
0 -8/9 1/3 -124/9
So the matrix looks like this now:
[tex]\left[\begin{array}{cccc}1&\frac{10}{9}&\frac{4}{3}&\frac{398}{9}\\0&-\frac{8}{3}&-4&-\frac{304}{3}\\0&-\frac{8}{9}&\frac{1}{3}&-\frac{124}{9}\\\end{array}\right][/tex]
Now, we can multiply the second row by -3/8 so we get:
[tex]\left[\begin{array}{cccc}1&\frac{10}{9}&\frac{4}{3}&\frac{398}{9}\\0&1&\frac{3}{2}&38\\0&-\frac{8}{9}&\frac{1}{3}&-\frac{124}{9}\\\end{array}\right][/tex]
Now, we can subtract: [tex]R_{1}-\frac{10}{9}R_{2}[/tex] so we get:
0 -10/9 -5/3 -380/9
1 10/9 4/3 398/9
------------------------------
1 0 -1/3 2
So the matrix will now look like this:
[tex]\left[\begin{array}{cccc}1&0&-\frac{1}{3}&2\\0&1&\frac{3}{2}&38\\0&-\frac{8}{9}&\frac{1}{3}&-\frac{124}{9}\\\end{array}\right][/tex]
Next, we do the following operation: [tex]R_{3}+\frac{8}{9}R_{2}[/tex]
0 8/9 4/3 304/9
0 -8/9 1/3 -124/9
------------------------------
0 0 5/3 20
So our matrix will now look like this:
[tex]\left[\begin{array}{cccc}1&0&-\frac{1}{3}&2\\0&1&\frac{3}{2}&38\\0&0&\frac{5}{3}&20\\\end{array}\right][/tex]
We next multiply R3 by 3/5 so we get:
[tex]\left[\begin{array}{cccc}1&0&-\frac{1}{3}&2\\0&1&\frac{3}{2}&38\\0&0&1&12\\\end{array}\right][/tex]
and now we do: [tex]\frac{R_{3}}{3}+R_{1}[/tex]
0 0 1/3 4
1 0 -1/3 2
------------------------------
1 0 0 6
So our matrix will now look like this:
[tex]\left[\begin{array}{cccc}1&0&0&6\\0&1&\frac{3}{2}&38\\0&0&1&12\\\end{array}\right][/tex]
and now we do the following: [tex]R_{2}-\frac{3}{2}R_{3}[/tex]
so we get:
0 0 -3/2 -18
0 1 3/2 38
------------------------------
0 1 0 20
for our final matrix to be:
[tex]\left[\begin{array}{cccc}1&0&0&6\\0&1&0&20\\0&0&1&12\\\end{array}\right][/tex]
so now we can retrieve the corresponding answers:
R=6
G=20
T=12

Find the measure of the indicated arcs or central angles in OA. DG is a diameter.
Answer:
Arc DE = 90°
m<GAB = 82°
Arc DC = 49°
Step-by-step explanation:
Given:
m<EAF = 74°
m<EAD = right angle = 90°
Arc BG = 82°
Required:
Arc DE,
<GAB, and
Arc DC
Solution:
Recall that the central angle measure = the intercepted arc measure.
Therefore:
✔️Arc DE = m<EAD
Arc DE = 90° (Substitution)
✔️m<GAB = arc BG
m<GAB = 82° (Substitution)
✔️Arc DC = m<CAD
Find m<CAD
m<CAD = ½(180 - m<GAB)
m<CAD = ½(180 - 82)
m<CAD = 49°
Arc DC = m<CAD
Arc DC = 49°
