Given the that the speed of light in a vacuum is about 3.0x10 to the power of 8 meters per second how far does light travelin two weeks
using scientific notation
The light travel in two weeks is 1.2700 × [tex]10^1^5[/tex] m/ week
In the given statement is :
The speed of light in a vacuum is about 3.0 x 10^8 m/sec
We know that , Formula of speed i.e.,
Speed = distance / Time
Use dimensional analysis to find the answer:
[tex]3.0[/tex] × [tex]10^8 m/s[/tex] × 60s/min × 60min./ h × 24 h/ day ×7 days/week × 7 days/week
=[tex]3.0[/tex] [tex](60)^2 (24)(7)(7)[/tex] × [tex]10^8[/tex] = 12,700,800 × [tex]10^8[/tex]
= [tex]1.2700[/tex] ×[tex]10^7[/tex]×[tex]10^8[/tex]
= [tex]1.2700[/tex] × [tex]10^7^+^8[/tex]
= 1.2700 × [tex]10^1^5[/tex] m/week
Hence, The light travel in two weeks is 1.2700 × [tex]10^1^5[/tex] m/ week

4. Which of the following differences could not give a distance between two points on a number line? Explain why. a. 19-7 c. -12-(-7) b. -3 - (-18) d. 14-(-6)
-12 -(-7) could not be a distance.
Distance:
Distance traveled is the total length of the path traveled between two positions. It can either be a 0 or a positive number that's mean it can never be a negative number.
So from the above-given statement we have
a) 19-7 = 12 (which is positive number)
b) -12 - (-7) = -12 + 7 = -5 ( which is a negative number)
c) -3-(-18) = -3 + 18 = 15 ( which is a positive number)
d) 14-(-6) = 14 + 6 = 20 ( which is a positive number)
Therefore option b i.e., -12 - (-7) cannot be a distance between two points on a number line.

Team Z can do the work in 26 days, and working together Team Z and Y can do the same work in 14 days. How many days would it take for Y alone to do the work? Round your answer to the nearest whole number.
Answer:
30 days
Step-by-step explanation:
The above question is solved as shown below:
Working together Team Z and Y can do the same work in 14 days.
1/Team Y + 1/Team Z = 1/14 days
Team Z can do the work in 26 days,
Hence:
1/Team Y + 1/26 days = 1 /14 days
= 1/ Team Y + 1/26 = 1/14
1/Team Y = 1/14 - 1/26
The Lowest Common Denominator = 182
Hence:
1/Team Y = 13 - 7/182
1/Team Y = 6/182
Cross Multiply
Team Y × 6 = 1 × 182
Team Y = 182/6
Team Y = 30.33 days
Approximately to the nearest whole number = 30 days
Therefore, Team Y alone can do the job in 30 days

What is m∠2 + m∠3? Explain. Two lines and two line segments. Lines A B and C D are parallel horizontal lines with point C directly below point A and point D directly below point D. A vertical segment extends from A to C. A diagonal segment extends from C to B. Angle B A C is labeled 1. Angle A C B is labeled 3. Angle B C D is labeled 4. Angle A B C is labeled 2. A. 180; m∠1 + 90 = 180, so m∠2 + m∠3 = 180. B. 180; m∠1 + 90 = m∠2 + m∠3, so m∠2 + m∠3 = 180. C. 90; m∠1 + m∠2 + m∠3 = 180. m∠1 = 90, so m∠2 + m∠3 = 90. D. 90; ∠2 and ∠3 are corresponding angles, so m∠2 + m∠3 = 90.
The line AB and the segments AC and BC form triangle ∆ABC, which gives the measure of m‹2 + m‹3 as following option;
C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°
How can m‹2 + m‹3 in ∆ABC be calculated?From the given descriptions, we have;
Lines AB and CD are horizontal lines.
Segment that extends from A to C which is segment AC is a vertical line
Therefore;
m‹BAC = m‹1 = 90°
‹BAC, ‹ABC, and ‹ACB, which are angles 1, 2, and 3 are interior angles of ∆ABC
Which gives;
m‹1 + m‹2 + m‹3 = 180° (sum of interior angles of a triangle theorem)
Therefore;
90° + m‹2 + m‹3 = 180° (substitution property)
m‹2 + m‹3 = 180° - 90° = 90°
m‹2 + m‹3 = 90°
The correct option is therefore;
C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°Learn more about the interior (and exterior) angles of a triangle here:

Answer:
The identity property of addition
Step-by-step explanation:
Jamal uses the steps below to solve the equation 6x – 4 = 8.
Step 1: 6x – 4 + 4 = 8 + 4( Addition step of equality)
Step 2: 6x + 0 = 12

Converting centimeters to metersIn order to convert centimeters to kilometers, we will use the conversion factor below.
100cm = 1m
1000m = 1km
Given 3cm
3cm = 3/100 m
3cm = 0.03m
Convert to km
Since 1000m = 1km
0.03m = 0.03/1000
0.03m = 0.00003km

The Outdoor Furniture Center buys wooden benches for $50 each. The owner of the Outdoor Furniture Center sells the benches for a 120% markup. At the end of the season, the owner wants to sells all the benches that are in stock. He sells the benches for 20% off.
What is the total price of a bench with the 20% discount plus a 5% sales tax?
Practice
Show your work
Answer:
92.4
Step-by-step explanation:
50$ + 120% = 110
110 - 20% = 88
88 + 5% = 92.4
The total price of a bench with the 20% discount plus a 5% sales tax is $92.4.
What is Markup Percentage?Markup percentage is defined as the total profit of the commodity in terms of percentage. It is calculated by dividing the difference of the selling price and the cost with the cost and then multiply to 100.
Markup Percentage = [(sales price - cost) / cost] × 100
Cost of a bench = $50
There is 120% markup in the bench
Selling price = $50 + ($50 × 120%)
= $50 + ($50 × 1.2)
= $50 + $60
= $110
At the end of the season, owner gives 20% discount.
Price of the bench after 20% discount = $110 - (20% × 110)
= $110 - (0.2 × 110)
= $110 - $22
= $88
There is a sales tax of 5%.
Last selling price of the bench = $88 + (5% × $88)
= $88 + (0.05 × $88)
= $88 + $4.4
= $92.4
Hence, the owner sells the bench at the season at $92.4.
