Answer:
The club made 5 pies
Step-by-step explanation:
Total pieces=40
40/5 (cuz each pie was cut in 5 pieces)
40/5=8 (Total of pies sell)
But they say the cafeteria contributed with 3 pies so:
8-3= 5
Answer:
x=3
Step-by-step explanation:
Use the Pythagorean Theorem to write an equation.
x^2+y^2=z^2
Substitute values from the problem.
x^2 + 6^2 = 9^2
Solve for what you know.
x^2 + 36 = 81
Square root it.
x+6=9
Subtract 6 from both sides.
x=3
In the future, if you see a right triangle with an unknown side, and the other two sides are either 3, 6, or 9, you know that the other one is the missing value out of 3/6/9. This is called a 3/6/9 triangle.
Answer:
12/13
Step-by-step explanation:
First, use the pythagorean theorem to find EF
5^2 + EF^2 = 13^2
You get: EF = 12
Sin is opposite over hypotenuse. 12 represents the opposite and 13 represents the hypotenuse.
