The correct answer is A.
Answer: Sin0 = 8/8.5
Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).
The Sine of the angle is calculated as
Sin0 = opposite/hypotenuse
We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.
To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,
X² = 3² + 8²
X² = 9 + 64
X² = 73
Adding the square root sign to both sides of the equation, we now have
X = √73
X = 8.5 (approximately)
Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as
Sin0 = opposite/hypotenuse
Sin0 = 8/8.5
Answer:
91 more marbles
Step-by-step explanation:
Step 1: find how many jars you need to fill
to do this you will have to solve this equation: 11–7 3/4 = 3 1/4
Step 2: find how many marbles you need
to do this you will have to solve this equation: 3 1/4 X 28 = 91
this tells you there are 91 marbles in 3 1/4 of the jars thus you need 91 more marbles.
hope this helps you!!!
This question is actually really easy!
All you need to do is divide 36 by 12.
And you get... 3!!!
