Answer:
56.96°
Step-by-step explanation:
The set up will give a right angles triangle where;
The height of the sky scraper = hypotenuse side = 396m
The length of the shadow will be the opposite = 332m
According to the SOH trig identity
sin theta = opp/hyp
sin theta = 332/396
sin theta = 0.8383
theta = arcsin 0.8383
theta = 56.96°
Hence the sun is at 56.96° above the horizon
Answer:
I think its B, but I could be wrong.
Step-by-step explanation:
You can solve this one by adding their rates, but you have to invert the numbers they give you to find the rate. Rate is measured in something per unit of time, and "per" indicates division. So the rates are: 1/3 of an hour (Sally) and 1/6 of an hour (Steve). So add the rates: 1/3 + 1/6 = 1/2. (1/3 is 2/6, and 2/6 + 1/6 = 3/6). Since their combined rate is 1/2 of a room in one hour, it takes them two hours to paint the room.
This answer makes sense: It takes Sally three hours by herself; with Steve's help, she's faster, but not THAT much faster, because he's pretty slow. You can often spot-check word problem answers like this by giving it a common sense once-over. If we came up with four hours, that would clearly be wrong: it should take her LONGER if she's getting help.
Answer:
15187.5=2000(1.5)^5
Step-by-step explanation:
So right now he has 2000 in his saving each year it grows by 1.5 so by year 5 it should be
15187.5 in his savings
hope I did it right
