Answer:
d
Step-by-step explanation:
when you are dividing like numbers with different exponents, subtract them
Answer:
4
Step-by-step explanation:
add the numbers up
you get 64
one pound is 16 ounces so divide 64 by 16 and you get four pounds
That question isn't nearly as hard as they want it to be. The "a" in the sin function is the altitude of the function...how high it goes up and how low it goes down. The negative in front of the 7 just means that it starts going down before it goes up (a classic sine wave goes up and then down; the negative just reverses that). From the wave's midpoint on the y axis, which is 11 (hence, the +11 in the equation), the wave goes up 7 (to a y value of 18) and then goes down 7 (to a y value of 4). Because it goes up 7 and then down 7, the diameter of the pinwheel is 14. The sin wave mimics the round and round motion of the pinwheel. You could have been able to tell that it was 14 just by looking at what the altitude was. The altitude is always the number the wave goes up and down from its midpoint. 7 up and 7 down makes 14 altogether.
8*30 = 240
And after you divide it by 3 is 80.
M = 80 final answer
Answers is A
B & D show n and 8 being multiplied and it says sum
if n=28 then that makes -16=16 on C and that is incorrect
when you plug in 28 for n on A it is 16=16
