Speed of the sound = meters per second
Time to calculate the distance traveled = 3*10' 10 seconds
Since,
1.0*10 ' 13
Distance = Speed x Time
Using the values we get:
distance =3.4*10'2*3+10´30
3.4*3*10' (2+10)
10.2*10' 12
Since the calculators show the final answer is scientific notation, the above answer in scientific notation would be:
Distance = 1.02*10°13
Answer: 4
Step-by-step explanation:
Answer:
1) future value = present value x [1 + (i x n)] = $300 x [1 + (3.5% x 4)] = $342
2) using the compound interest formula:
future value = $225 x (1 + 4.1%)¹°⁵ = $238.98
Using the simple interest formula doesn't yield the same answer = $225 x [1 + (4.1% x 1.5)] = $238.84. In this case it is close due to a very short period of time and low interest rate.
3) future value = present value x (1 + i)ⁿ = $1,700 x (1 + 6%)⁴ = $2,146.21
since the interest is annual, we must convert 48 months to 4 years
Answer:
3.186 x 10^8
Step-by-step explanation:
3.2× 10^8 = 320,000,000
1.4 × 10^6 = 1,400,000
320,000,000 - 1,400,000 = 318,600,000
318,600,000 = 3.186 x 10^8
- you get to the power of eight, by counting the amount of spaces the decimal moved over (moving to the left increase, but right decreases)
Answer:
Area of square is 625 cm².
Explanation:
Side (length) = 25 cm
As we know, all the sides of the square are equal.
Further,
Area of the square = (side) ²
Area = ( 25 )²
Area = 625 cm²
Therefore, area of the square is 625 cm².
