Answer: See the attached image
You have the correct idea for the boxes you've filled out. For the first three boxes in column 1, I would be specific which segments you are dividing. So for instance, in the first box, it would be EG/EB = 55/11 = 5. Then the second box would be EF/EC = 35/7 = 5, and so on. The order of the boxes doesn't matter. The three boxes then combine together to help show that the triangles are similar. Specifically [tex]\triangle EFG \sim \triangle ECB[/tex]. The order of the letters is important to help show how the angles pair up and how the sides pair up. We use the SSS similarity theorem here.
The second problem is the same idea, but we use one pair of congruent angles. So we'll use the SAS similarity theorem this time.

A teacher has a box of 88 colored pencils. He gave 46 away. The teacher put the rest of the colored pencils into 7 equal groups
How many colored pencils are in each group?
Answer:
6 pencils in each group
Step-by-step explanation:
Total = 88
Gave away = 46
Balance = 88 - 46 = 42
Divided into 7 groups, means : 42/7 = 6
So each group has 6 pencils

A controversial story comes out in the school newspaper. The number of students who have not heard about the story decreases at a rate that is proportional at any time to the number of students who have not heard the story at that time. There were 900 students who had not heard the story initially, and the number of students is divided by 3 every 4 days. How many students have not heard the story after 7 days? Round to the nearest student. students Stuck?

The half-life of Iodine-131 is approximately 8 days. Find the amount of Iodine-131 left from a 42 gram sample after 16 days.
1) 0.0006 grams
2) 21 grams
3) 10.5 grams
4) 34 grams
Answer:
Step-by-step explanation:
The formula for this is
[tex]N=N_0(.5)^{\frac{t}{H}[/tex] where
N is the amount of the element left after a certain amount of time (for us it is measured in days),
N₀ is the initial amount of the element in grams,
t is the number of days gone by, and
H is the half life of the element. Filling in:
[tex]N=42(.5)^{\frac{16}{8}[/tex] which simplifies a bit to
[tex]N=42(.5)^2[/tex] and a bit more to
N = 42(.25) which gives us a remaining amount of
N = 10.5

3x + 2 = 17
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15[Division Property of Equality] Divide 3 on both sides: x = 5Answer:
you subtract two both side, then divide three both side, you'll get x = 5.
Step-by-step explanation:
3x + 2 = 17
(3x + 2) -2 = (17) -2. First, you subtract 2 for both sides
3x = 15
(3x)/2 = (15)/2. Second, you divide 3 both side
x = 5. Last, you get your answer

Tom has a 490-page book to read. If he has already read 56 pages, how many more pages should he read each week
o finish in 6 weeks?
Write an equation for the situation and then answer the question.
If he has read 56 pages and there are a total of 490, then how many are left? That's 490 - 56 = 434.
To read 434 pages in 6 weeks, he should read 434 / 6 pages each week. That's 72 1/3 pages per week.

Which of the following statements best describes a characteristic of an observational study?
The researcher determines relationships among variables.
The individuals are observed the exact way they act in real life.
The researcher imposes, for example, a treatment on the sample population and then observes their response.
It is the best method to learn about cause-effect relationships.
Answer:
The researcher determines relationships among variables.
The individuals are observed the exact way they act in real life.
Step-by-step explanation:
An observational study can be defined as a type of study in which a researcher observes and measures the effect of a diagnostic test, risk factors, or treatments on individuals without intervening, changing or manipulating who are or aren't exposed to it (controlled conditions).
Hence, the statements which best describes a characteristic of an observational study are;
I. The researcher determines relationships among variables.
II. The individuals are observed the exact way they act in real life.
Additionally, an unobtrusive data collection is a data collection technique used mainly in the social sciences to obtain or gather data without the researcher directly interfering or interfacing with the subject being studied. Thus, it doesn't influence the behavior, action or response of the subjects under study.
