To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.
Divide the area of the combined areas and the total area to find the probability of landing on a triangle.
A = 1/2bh
1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)
A = bh
26 x 26
A = 676 square inches
128/676 = 0.189
There is an approximate probability of 0.19 of hitting a triangle.
Answer:15 1/2 miles per gallon
Step-by-step explanation:
Since you want to find the unit rate you have to find the miles per gas.
You divide and get 15 1/2miles per gallon
Answer:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Step-by-step explanation:
For this case we have the function of the height in terms of the time givenby:

And we want to known when the rockect hit the ground and for this case we need to solve the equation 

And as we can see we have a quadratic equation like this one:

Where: 
And the general solutions are given by:

If we replace the values that we have we got:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Answer:
a13=310.7
Step-by-step explanation:
Formula= an=a1r^n-1
a13=1100(0.9)13-1
a13=310.7
Answer:
0.01000188
Step-by-step explanation:
The third term is ...
8C2·x^6·y^2 = 28 x^6 y^2
Putting in the given values for x and y, we get ...
28·3^6·7^2·10^-8 = 1000188×10^-8 = 0.01000188
_____
8C2 = 8!/(2!·(8-2)!) = 8·7/(2·1) = 28
