389.775 you would do 809.45 divided by 2 then subtract 14.95 from that answer to get 389.775
Answer: 33.6
Step-by-step explanation:
tan(angle) = opposite/adjacent
tan(40) = x/40
40*tan(40) = x
x = 40*tan(40)
x = 25*0.8390996312
x = 33.56398525
So the tree is roughly 33.6 feet tall
Answer:
- 124+73
- 73 miles
- 28% decrease
Step-by-step explanation:
1. Subtracting a number is the same as adding its opposite. The opposite of -73 is 73, so subtracting -73 is the same as adding 73:
... 124 -(-73) = 124 +73
2. Lamar drove 48+55 = 103 miles, but that is not what the question asks. Rather, it asks the straight-line distance from where he is to where he started. That distance (d) is the length of the hypotenuse of the right triangle that has 48 mile and 55 mile legs. The Pythagorean theorem is used to calculate the straight-line distance in such cases.
... d² = 48² + 55²
... d² = 2304 + 3025 = 5329
... d = √5329 = 73 . . . . miles
3. The percentage change between two numbers is calculated from ...
... percent change = ((new value) - (old value))/(old value) × 100%
Putting in your numbers, you have ...
... percent change = (120.96 -168)/168 × 100% = -47.04/168 × 100%
... = -0.28 × 100% = -28%
The minus sign indicates the change is a <em>decrease</em> of 28%.
Answer: i believe the answer is c=37. explanation: the two lengths are equal so if one side equals 2c and the other is c+37 then c+37 is just c+c making c equal to 37
It's 1017.88 hope this helps
