Step-by-step explanation:
n × (−2+5 ) = −8+20
n × 3 = 12
n = 4
2 + (n+6) = −1+6
n + 8 = 5
n = -3
I believe (3*8)*6=3*(8*6) illustrates the associative property of multiplication.
(3*8)*6=3*(8*6)
24*6=3*48
144=144
Answer:
The change is increasing with a percentage of change of 64%
Step-by-step explanation:
Since we have the present grater than the original, then the change is increasing
Secondly, we want to calculate the percent of change
Mathematically , that will be ;
(present - original)/original * 100%
= (90-55)/55 * 100%
= 35/55 * 100% = 63.63 which is approximately 64%
The zip line forms a right triangle with the tree, when elevated
The height of the tree is 35 meters
<h3>How to calculate the height of the tree</h3>
Represent the height of the tree with h.
So, the height h is calculated using the following sine function

Make h the subject
h = 200 * sin(10)
Evaluate the product
h = 35 meters
Hence, the height of the tree is 35 meters
