Answer:
y = -6 PLEASE GIVE BRAINLIEST
Step-by-step explanation:
-15 - 9y = 39
39 + 15 = 54
-9y =54
y = 54 ÷ -9 = -6
y = -6
Answer:
21/55
Step-by-step explanation:
Since there are already 2 girls on the relay team, what is left is to select 2 individuals be it a girl or a boy from the remaining 7 boys and 4 boys.
This can be done in 11C2 ways, and this equal 55 ways.
Now, we were told that we want exactly 2 boys on the team to join the other 2 girls already on the team. This mean we select 2 boys from the 7 boys. This can be done in 7C2 ways and this equals 21 ways.
Our probability is now 21/55
Answer:
25
Step-by-step explanation:
1125-900=225
225/900×100=25
Answer:
60in^2
Step-by-step explanation:
Area of a triangle = Height x Base X 1/2
Base = 10
Other 2 sides = 13
Now, let's split the Base into 2 parts.
=> 1 part = 5 and 2 part = 5
We can find the height using Pythagorean theorem
=> Isosceles triangle
=> (1 part of the base)^2 + Height^2 = The Hypotenuse^2 = the longer side of a triangle = 13^2
=> 5^2 + Height ^2 = 13^2
=> 25 + Height^2 = 169
=> 25 - 25 + Height ^2 = 169 - 25
=> Height^2 = 144
=> Height = Square root of 144
=> Height = 12
Area = 12 x 10 x 1/2
=> 12 x 5
=> 60 in^2
So, the Area is 60 in ^2
