Answer:
The answer is the first option
hope this helps
Step-by-step explanation:
You can count the spirals because they are coloured.
The left handed spirals are in red and you can count 13.
The rifht hanged spirals are in yellow and you can count 21.
Fibonacci sequence is: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... From 2 the next number is the sum of the two previous numbers:
2 = 1 + 1
3 = 2 + 1
5 = 3 + 2
8 = 5 + 3
13 = 8 + 5
21 = 13 + 8.
Fibonacci numbers are found in many structures in nature.
We have just found that these cacti enclose Fibonacci numbers 13 and 21.
Answer: 13 and 21
Answer: 10
Why?
3*9+2y=47
3*9= 27
27+2y=47
47-27= 20
2y=20
20/2=10
Y=10
Hope this helps :D
we know that
A number is an inequality solution if the number satisfies the inequality
<u>Part 1)</u>
rewrite the inequality
The answer Part 1) is the option D
Because satisfies the inequality
-----> is true
<u>Part 2)</u>
The answer Part 2) is the option A
Because satisfies the inequality
-----> is true
<u>Part 3)</u>
we're going to verify every case
<u>case A)</u> For
substitute the value of x in the inequality
------> is true
therefore
The number is a solution
<u>case B)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case C)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case D)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
therefore
The answer Part 3) is the option A
