Answer:
61.97 feets
Step-by-step explanation:
Using trigonometry :
Horizontal distance between the person and building,
Let distance = d
Tan 15 = 15 / d
0.2679491 * d = 15
d = 15 / 0.2679491
d = 55.980781
To obtain the height, h :
tan 40 = (h-15)/d
d = 55.98
h-15 = 55.98 (tan 40°)
h - 15 = 55.98 * 0.8390996
h - 15 = 46.972797
h = 46.972797 + 15
h = 61.972797
h = 61.97 feets
She will need 30 apples more and 200 apples in total.
Answer:
B.
Step-by-step explanation:
If you add the presents then calculate that percent off of of her last paycheck you will find your answer
Y is 15 :)
Explanation:
If you divide 3/2, you get 1.5. 15/10 is also get 1.5
Another way of doing this is by cross multiplying. Multiply 3 by 10 to get 30 on the right side of the equation. Multiply 2 by y to get 2y. Then divide both sides by 2 and you get y = 15.
5% interest compounded annually for 3 years multiplies the initial balance by
... 1.05^3 = 1.157625
5% simple interest for 3 years multiplies the initial balance by 1 + 3*0.05 = 1.15.
The difference of these multipliers is
... 1.157625 - 1.15 = 0.007625
If the difference in account balance is Rs 61.00, then the invested principal amount P is
... P*0.007625 = 61.00
,.. P = 61.00/0.007625 = 8000.00
The sum of money is Rs 8000.
