Answer:
Step-by-step explanation:
x/13=10
We have to get rid of the 13. (the denominator)
How?
By multiplying 2 sides by 13
Remember the Rules of Maths:
1. Whatever you do to one side, you must do to the other.
2. Use the opposite operation.
So, we used Rule 2 to get rid of the 13.
Now:
x=10*13
(On the left side, the 13s cancel)
x=130
It is always a great idea to double-check
Does 130 divided by 13 equal 10?
Of course it does!
Have a great day!!
I hope everything is clear!
Answer:
The answer would be B
Step-by-step explanation:
Your mean is 602.4, and your median is 609
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=<u>O</u>pposite over <u>H</u>ypotenuse
Cos=<u>A</u>djacent over <u>H</u>ypotenuse
Tan=<u>O</u>pposite over <u>A</u>djacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be 
and cos A (adjacent over hypotenuse) would be 
.
I hope this helps!
