The answer would be 1/4 and in decimal form 0.25
1/2 * 3/6 (Reduce 4/8 to 1/2)
1 * 3 over 2 * 6 (Use the butterfly multiplication method)
3 over 2 * 6 (Reduce 1 * 3 to 3)
3/12 (Reduce 2 * 6 to 12)
1/4 (Now lastly reduce once more and u get this)
0.25 decimal form if needed.
Set up the composite function and evaluate
f(3x^2/2)=9x^4+3
Answer:
90 meters squared
Step-by-step explanation:
First you multiply 10*4.5=45
Then you multiply 45 and 2 because 1cm=2m
45*2=90
3x and -2x are like terms because they both have the variable X
Answer:
15 miles
Step-by-step explanation:
Let's say the dock is at the origin on a coordinate plane and each unit is 1 mile. If the boat travels 9 mile due north, that means that we move up from the origin (0, 0) 9 units to point A (0, 9). Now, this boat moves 12 miles due west, so we will go 12 units to the left of (0, 9) to point B (-12, 9). See the attached drawing (sorry for the crudeness).
Notice that this is a right triangle with legs of 9 and 12. That means the distance from the boat to the dock is just the hypotenuse, so use the Pythagorean Theorem: distance = 
Thus, the answer is 15 miles.
Hope this helps!
