You can draw a diagram of the situation, representing it by a right triuangle.
In the right triangle the hypotenuse is the distance indicated by the radio signal, 1503 m, and the angle is 41°.
The opposed leg to 41° is the height of the ballon.
Then you can use the sine trigonometric function.
sine (41°) = opposed leg / hypotenuse = x / 1503 m => x = 1503m * sine(41°)
=> x = 986m.
Answer: 986m
Answer:
32/25
Step-by-step explanation:
Any finite-length, or repeating, decimal number is a rational number. Perhaps you want the number expressed as the ratio of two integers.

You can start by recognizing that the value of the number is one hundred twenty-eight hundredths, or 128/100.
This improper fraction can be reduced by removing a factor of 4 from numerator and denominator:
128/100 = 32/25
Answer:
78
Step-by-step explanation:
180-90-12=78
Answer:
Step-by-step explanation:
<u>Use compound interest formula</u>
- A = P(1 + r)^(nt), where A- future amount, P - invested amount, r- interest rate, t- time, n- number of compounds per year
<u>Given:</u>
- P = $2975
- r = 4% = 0.04
- t = 2.5 years
- n = 1
<u>Substitute the values and calculate:</u>
- A = 2975(1 + 0.04)^2.5 = 3281.48
Correct choice is B
I think it’s 3/8 I’m not sure tho good luck
