8 gorrilas
Explanation:
The ratio of monkeys to gorrila = 5:2
This means there are 5 monkeys for every 2 gorrilas
when there are 20 monkeys,
let the number of gorrilas = x
5 monkeys = 2 gorrilas
20 monkeys = x
cross multiply:
5(x) = 20(2)
5x = 40
divide both sides by 5:
5x/5 = 40/5
x = 8
Hence, if there were 20 monkeys, we would have 8 gorrilas.
Answer:
Step-by-step explanation:
For this case we have the following value:
We can convert this first to 
like this:
Now we use the fact the the pressure is defined as 
, whre P is the pressure, F the force and A the area, so then 
and then we can replace this:
Now from definition of work we know that 
where W is the work, F the force and d the distance, so then is equivalent 
And if we replace this into the equation we got:
Hello there! This statement is TRUE.
The question is asking you if it is true that 11 - 4 is greater than 4 + 2. To get an answer, Solve both of the problems.
11 - 4 = 7.
4 + 2 = 6.
So, is 7 greater than 6? Yes, it is greater than 6 by 1. This means the answer is true. I hope this was helpful and have a great rest of your day!
Answer:
- <u>f(t) = -7.561(t + 1.15)(t - 2.53)</u>
Explanation:
The<em> hint </em>is that the function f can be written in the form:
- f(t) = c (t - t₁) (t - t₂)
It is a quadratic function, i.e. a parabola.
The maximum point, maximum height, of a parabola is its vertex.
And the x-coordinate of the vertex is at the midpoint between the two x-intercepts.
The time when the rock reaches the road is one x-intercept: t = 2.53 seconds: (2.53, 0).
The other x-intercept is sucht that (x + 2.53) / 2 = 0.69
- (x + 2.53) / 2 = 0.69
- x + 2.53 = 1.38
- x = 1.38 - 2.53
- x = -1.15
Thus, the equation is:
- f(t) = c(t + 1.15) (t - 2.53).
You can find c by doing t = 0, because at t = 0 the height, f(t), is 22 feet:
- f(0) = 22 = c (0 +1.15)(0 - 2.53)
- 22 = c(1.15)(-2.53)
- 22 = c (-2.9095)
- c = - 22/(2.9095)
- c = - 7.561
Then, the function can be written as:
- f(t) = -7.561(t + 1.15) (t - 2.53) ← answer
