Answer:
Option B
Step-by-step explanation:
you should add both the powers that is
2/5 +2/9
28/45
For the value of x = 10, then the value of function f [g(10)] is 198. Then the correct option is D.
<h3>What is a function?</h3>
The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The following functions f(x) and g(x), solve f [g(10)]. f(x) = 10x + 8 g(x) = x + 9.
put g(x) in place of x in the function f(x). Then we have
f [g(x)] = 10(x + 9) + 8
f [g(x)] = 10x + 90 + 8
f [g(x)] = 10x + 98
Put x = 10, then we have
f [g(10)] = 10(10) + 98
f [g(10)] = 100 + 98
f [g(10)] = 198
Thus, for the value of x = 10, then the value of function f [g(10)] is 198. Then the correct option is D.

Answer: This is an reduction.
Step-by-step explanation:
- A dilation a king of transformation that creates an similar image (about a center of dilation) of the actual figure by changing its size with the use of a scale factor(k).
- It either shrinks or stretches the image.
- If |k| is greater than 1 then the image is an enlargement .
- If |k| is less than 1 then the image is an reduction.
- If |k| is equals to 1 then there is no change in size.
Given : A street is drawn by dilating segment 
about center A with a scale factor greater than 0 but less than 1.
Then by using (2.) , we can say that this is an reduction.
Answer:
60%
Step-by-step explanation:
You can solve this problem by setting up a system of equations.
Let's say that the number of tickets bought by students in the first year is x, and the number bought by continuing students is y. From there, you can set it up like this:
0.4x+0.2y=160
x+y=500
Now, you can multiply the first equation by 5 on both sides to get:
2x+y=800
Subtracting the second equation from the first equation now yields:
x=300
y=200
Since 300 of the 500 tickets bought were from the first year students, and 300/500 is 0.6, 60% of the students who bought the ticket were first year students. Hope this helps!
