The value of the missing side of the triangle is 24.
What is the similarity?Similarity refers to the degree of resemblance or likeness between two or more things, concepts, or ideas. It can be measured in various ways, depending on the context and the characteristics being compared.
Scale factor refers to the ratio of the size of an object in the original form to its size in the scaled or transformed form. It is commonly used in geometry and mathematics to describe how the dimensions of an object have changed after a transformation such as scaling, stretching, or shrinking.
From the given figure the value of the missing number is calculated as,
36 / 24 = x / 16
x = ( 8 x 3 )
x = 24
Therefore, the value of an unknown number is x = 24.

Last month, you joined an online strategy game. When you joined, there were 50 members. Since then, 41 members have quit. What is the percent change in the number of
members from last month to this month?
Amount Decrease
Answers
Answer:
82% decrease
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
There were 50 members.
41 left.
50 - 41 = 9
The new number of members is 9.
percent change = (9 - 50)/(50) * 100%
percent change = -82%
A negative percent change is a decrease.

{x | 0 < x ≤ 5}
Step-by-step explanation:
The domain of a function describes all the values x could taken on in order to produce an output. You can notice the value of x is farthest left at a value of 0, which has an open dot and the value of x that is farthest right is at 5 with a closed dot. A closed dot includes the value while an open does not. This means x can be equal to 5, but not zero. We can write our domain as follows:

Match the percent on the left with the appropriate estimate on the right
32% 20%
22% 70%
74% 1/2
51% 30%
Answers
Answer:
32% goes to 30%. 22% goes to 20%. 74% goes to 70%. 51% goes to 1/2.
Step-by-step explanation:
Just treat is as rounding. When you round, 32 goes to 30 because the 2 is 4 or less. 22 and 74 each respectively round to 20 and 70. 1/2 is equal to 50%. And 51% rounds to 50%, or 1/2.
The correct value of the percent on the left with the appropriate estimate on the right is,
32% - 30%
22% - 20%
74% - 70%
51% - 1/2
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
To match the percent on the left with the appropriate estimate on the right.
Now, We can simplify as;
32% = 0.32
22% = 0.22
74% = 0.74
51% = 0.51
20% = 0.20
70% = 0.70
1/2 = 0.5
30% = 0.3
Thus, The correct value of the percent on the left with the appropriate estimate on the right is,
32% - 30%
22% - 20%
74% - 70%
51% - 1/2

4t+10=20+2t (solve for t)
Answers
Answer:
t=5
Step-by-step explanation:
4t+10=20+2t
4t-2t=20-10
2t=10
t=10÷2
=5
4t + 10 - 2t = 20
2. Move 10 to the right-hand side and change its sign
4t - 2t = 20 - 10
3. Collect like terms
2t = 20 - 10
4. Subtract the numbers
2t = 10
5. Divide both sides by 2
2t = 10 ➗ 2
Write the value of t
