Gina saw 25 monkeys 
25 ÷ 5 = 5 
5 + 7 = 12
12 + 6 = 18
25 + 5 +12 + 6 = 48 animals

To celebrate getting a new job, Marco went out for a dinner that cost $100. If the localsales tax is 6% and Marco left a 15% tip
Art [367]

Answer:

$121

Step-by-step explanation:

So if the meal cost $100, finding out the percentages is pretty easy.

The sales tax is 6%, and 6% of 100 is simply 6.

15% of 100 is simply 15.

So, adding the total cost of the meal plus the sales tax plus the tip is simply $121.

Abe, Bob, Carl, Dan and Earl are going to stand in line for a photo. What is the probability that the boys will stand in alphabe
Levart [38]

Answer:

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

Step-by-step explanation:

Probability:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Arrangments of x elements:

The total number of arrangments of x elements is given by:

A_{x} = x!

Desired outcomes:

Standing in alphabetical order, so only 1 possible outcome, which means that D = 1

Total outcomes:

Arrangments of 5 people, so

T = A_{5} = 5! = 120

Probability:

p = \frac{D}{T} = \frac{1}{120} = 0.0083

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

How many triangles can be constructed with sides measuring 5 m, 16 m, and 5 m?
Ksivusya [100]

Answer:

Here we are given with the sides of the triangle as 5m, 16m and 5. The sum of the length of the two sides should be greater than the length of the third side. But this inequality fails here. Hence no triangle can be made.

Hope this helped

Given that F(x) = cos2(x + 9), find functions f,g and h such that F = fogoh
Vesna [10]

Answer:

The functions f(x), g(x) and h(x) such that F(x) = f\,\circ\,g\,\circ \,h (x) are f(x) = x^{2}, g(x) = \cos x and h(x) = x+9, respectively.

Step-by-step explanation:

Let F(x) = \cos ^{2}(x+9), if F(x) = f\,\circ\,g\,\circ \,h (x), then we derive f(x), g(x) and h(x) by using the following approach:

1) F(x) = \cos ^{2} (x+9) Given

2) f\,\circ\,g(x) =  \cos^{2} x  Definition of function composition/h(x) = x+9

3) f(x) = x^{2} Definition of function composition/g(x) = \cos x

4) f(x) = x^{2}, g(x) = \cos x, h(x) = x+9 From 2) and 3)/Result

The functions f(x), g(x) and h(x) such that F(x) = f\,\circ\,g\,\circ \,h (x) are f(x) = x^{2}, g(x) = \cos x and h(x) = x+9, respectively.
