Answer:
b
Step-by-step explanation:
because perimeter of rectangle is 2(l+b)
You can consider the tree perpendicular to its shadow, therefore you get a triangle rectangle of which you know the two legs and you need to find the angle between the shadow and the hypothenuse, opposite to the tree.
In this case, the angle α can be easily found with trigonometry:
tan α = (opposite side / adjacent side)
Therefore:
α = tan⁻¹ (tree / shadow) = tan⁻¹ (10 / 14) = 35°
NOTE:
tan⁻¹ is sometimes found written as arctan.
Answer:
4:1 ( i think)
Step-by-step explanation:
We can solve for a and b using substitution
a-b=3
a+b=5
solve and get that a=4 b=1
Which means that it's a 4:1 ratio
By the trend that is being given above, the population of New Jersey will only be 99.88% of the population from the previous year. It may be calculated through the following equation,
P(n) = P(0) x (1 - r)^n
Substituting the values from the given above,
P(n) = 79,318 x (0.9988)^(2015 - 2006)
= 78465.47
Thus, the population will approximately be 78,466.
A. 2/3x=6
B. I chose multiplication because division would be used to find the answer without an equation so I chose the inverse (or opposite) operation
