Answer:
-24
Step-by-step explanation:
-8/5 ( -3/2 ) ( -10 )
-8/5 ( -3/2 ) = 24/10 = 12/5 or 2 2/5
12/5 ( -10 ) = -120/5 = -24
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
72 / 3 = 24
So the answer would be 24 hours
First, let's construct an algebraic equation to formally find the answer:
Let x represent (the value of) the unknown number.
x²= 5x + 24 --- This equation shows that the (positive) number's square equals 24 more than 5 times the number.
Now we can solve for x (the number):
x² = 5x + 24
x² - 5x - 24 = 0
(x + 3)(x - 8) = 0
x = -3, 8
Therefore, this means that x (the number ) can be either -3 OR 8. Both will satisfy the description.
Hope this helps!
Answer:
The answer is a = 4.5
Step-by-step explanation:
To find this we start by dividing away the coefficient of a.
10a = 45 ----> Divide both by 10
a = 4.5
