Answer:
We want to simplify:
(3 + 1/4)*(3/5)
The first step is to write the first term as a single rational number.
We know that:
3*1 = 3
and 4/4 = 1
then:
3*1 = 3*(4/4) = (3*4)/4 = 12/4
We do this because we want to have the same denominator in both numbers, so we can directly add them.
Then we get:
(3 + 1/4)*(3/5) = (12/4 + 1/4)*(3/5) = (13/4)*(3/5)
And remember that in the multiplication of rational numbers the numerator are multiplied together and the same for the denominators, then we get:
(13/4)*(3/5) = (13*3)/(4*5)
If we solve the multiplications we get:
(13*3)/(4*5) = (39/20)
Now, we can notice that in the numerator we have two prime numbers, 13 and 3.
And in the denominators, we have a 4 (which is equal to 2*2) and a 5.
So the prime numbers in the numerator and the denominator are all different, this means that we can not simplify it furthermore.
Then we have:
(3 + 1/4)*(3/5) = (39/20)

Answer:
m<A=40°
m<B=55°
m<C=85°
Step-by-step explanation:
Add up all the angles to equal 180 because all triangles add up to 180.
(2x+5)+(x+15)+x=180
Simplify.
4x+20=180
Solve for x.
x=40.
Plug x into the equations. Hope this helps.
correct Ans:
P(H) = 0.60
P(W | H) = P(H and W)/P(H)=
0.33
0.20/0.60
my mistake:
P(H and W) = 0.20
