A light year is defined as the distance light travels in one year. One light year is 9. 46 x 10^12 kilometers. A galaxy is about 150. 000 light years wide. About how many kilometers wide is the galaxy?
Answers
Answer: One way to solve this problem is to multiply the distance of one light year by the width of the galaxy:
distance of galaxy = 150,000 light years x 9.46 x 10^12 km/light year
Using a calculator, we can evaluate this expression as:
distance of galaxy = 1.419 x 10^18 km
Therefore, the galaxy is about 1.419 x 10^18 kilometers wide.

note that the * mean times and / means divide since i can’t do math symbols here but hope that helped!!
Answer:
Step-by-step explanation:
Area of triangle = bh/2
Tri 1) (15*10)/2 = 75 sq. cm
Tri 2) (24*20)/2 = 240 sq. cm
Tri 3) (12*17)/2 = 102 sq. cm
Tri 4) (18*32)/2 = 288 sq. cm
Word prob) (15.25*18)/2 = 137.25 sq. cm
How do you find the area of a triangle?
Ans. Area of triangle = \(\frac{1}{2}\) × b × h ⇒ \(\frac{bh}{2}\)

Find the measure of the indicated angle

Answer:
? = 110
Step-by-step explanation:
We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.
All angles of a triangle always adds up to 180
Add all the known angles 25 + 45 = 70
Than subtract 180 - 70 = 110

Answers
Analysing the pie chart.
ANSWER:
Explain what features of the graph make it misleading.
This graph is highly misleading, seeing as numerical calculations don't add up to 100%, as the standard pie chart does. The numerical values of each section add up to 178% which makes this pie chart extremely hard to interpret upon first glance. (Keep this information, it'll be important!)
Describe what people seeing the graph might misinterpret because of the misleading features.
Seeing as most people look at percentages out of 100%, people may think that one section describes 68% of 100% of people who took a survey felt a certain way, when in reality, the calculations are just off. Not only are the titles of the pie chart sections extremely generic, they don't give much context to the situation, even with the title in mind.
Designing a new pie chart.
Design a new version of the graph changing the misleading features so that the graph is no longer misleading. Use the same data provided in the original graph.
EXPLANATION:
1. We will start with the title and our section names. We have three sections based on the title 'Biggest COV-19 Worries,' which we can keep. We can rename our titles in this manner:
Getting It ---> Contracting COV-19
Family Getting It ---> Relatives Contracting COV-19
The Economy ---> COV-19's Effect on US Economy
2. Now we can look at percentages. I'll give an explanation and then I'll give numerical values for your recreation of the pie chart:
Since our pie chart has a whole value of 178%, we need to convert our numerical values to 100%. (ex. 89% of 178% = 50% of 100%) We can use simple decimal/percentage conversion for this.
68% of 178% = 38.2% of 100%
62% of 178% = 34.8% of 100%
48% of 178% = 26.9% of 100%
If we round these all accordingly, we get 38%, 35%, and 27%, which all add up to 100%.
Now we can create the bar graph with the right proportions for a bar graph of our values.
ANSWER/GUIDE:
38% corresponds to 'COV-19's Effect on US Economy,' 35% to 'Relatives Contracting COV-19,' and 27% to 'Contracting COV-19.'
(There are a few websites that allow you to make pie charts with numeric values, titles, and section names. Hope you're able to use one.
With our new graph, we corrected the misleading percentages in the pie chart, the generic and bland language of the descriptions, and made the graph much easier to read and interpret.
Why things like this shouldn't happen.
Write a short paragraph -- at least 3 sentences -- explaining why people need to examine graphs closely and what features to look for so they can identify misleading graphs.
ANSWER:
Things like this cannot happen as it can lead to make wrongful assumptions or claims. Not only will this confuse someone, it simply miseducates everyone who tries to interpret the graph as written. When expressing something highly important such as the COV-19 pandemic, you want to make sure you are giving credible and reliable information. When you're making graphs such as this, you want to look for three main things:

a. 2/12

c. 3/6
d. 8/12
Answers
Answer: D. 8/12
Step-by-step explanation:
8/12 is the equivalent fraction to 2/3 which we can see when the fraction is put into it's simplest form.
See here: In the fraction 8/12, there is an 8 as the numerator (top number) and a 12 as the denominator (bottom number). When we look at these, it is crucial to find the GCF (greatest common factor) so it can be put into simplest form. In this case, 8's factors are (1x8) and (2x4). 12's factors are (1x12), (2x6), and (3x4). Looking at these factors for both numbers, we can see that they both have a 2 and a 4. However, because the 4 is the greater number, it is our GCF. Now divide the numerator and the denominator by 4 to get 2/3

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
