There isnt a way the LCD can go lower, because 5 only counts by 5's and 5 and 8 meet at 40.
Answer:
least common denominator of 5 and and 8 is 40
B.5.0m/s
C.10m/s
D.15m/s
The vehicle's acceleration if its value may b assumed to be constant is 10 m/s. Therefore, option C is the correct answer.
Given that, a vehicle designed to operate on a drag strip accelerates from zero to 30m/s while undergoing a straight line path displacement of 45m.
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction-or change both.
Here, Δx = 45 m, v₀ = 0 m/s and v = 30 m/s
Using the formula v² = v₀² + 2aΔx
(30 m/s)² = (0 m/s)² + 2b (45 m)
b = 10 m/s
The vehicle's acceleration if its value may b assumed to be constant is 10 m/s. Therefore, option C is the correct answer.

Answer:
C. 10 m/s²
Step-by-step explanation:
Given:
Δx = 45 m
v₀ = 0 m/s
v = 30 m/s
Find: a
v² = v₀² + 2aΔx
(30 m/s)² = (0 m/s)² + 2a (45 m)
a = 10 m/s²
Could someone tell me how to solve this?
The electric generator has an efficiency of approximately 66.67%, which means that 66.67% of the input energy is converted into usable electrical power.
The question wants to know about the efficiency of an electric generator. The efficiency of any engine or generator is defined as the ratio of useful energy output to the energy input. In this case, the energy input to the generator is 120 hp (horsepower) and the useful energy output (i.e electrical power) is 80 hp.
The formula used to calculate the efficiency is: Efficiency = (useful energy output / energy input) * 100% , Using this formula, the efficiency of the generator would be (80 / 120) * 100% = 66.67 % .
This means that 66.67% of the energy supplied to the generator is successfully converted into electrical power, while the rest is likely lost as heat or other forms of non-usable energy.

The value of the expression (0.5)^4 is 0.0625.
In this expression, (0.5) raised to the power of 4 means that you multiply 0.5 by itself four times.
So, it would be calculated as 0.5 x 0.5 x 0.5 x 0.5, which equals 0.0625.
When you raise a number less than 1 to a positive exponent, like in this case, the result is a smaller number because you are repeatedly dividing the original number by itself, which makes it smaller each time.
In this case, 0.5 is divided by itself four times, resulting in a much smaller value, 0.0625.
To explain further, exponentiation represents repeated multiplication. When you raise a number to an exponent, you are essentially multiplying that number by itself the specified number of times.
In this case, (0.5)^4 means multiplying 0.5 by itself four times, leading to the value 0.0625.
This concept is fundamental in mathematics and is used in various applications, including calculating compound interest, population growth, and many scientific calculations where values change over time or with repetition.

The formula for the volume of a cylinder is V 7r²h, where r is the radius of the cylinder and his the
height of the cylinder. Rewrite the formula to solve for h in terms of r and V.
G
To solve for the height of a cylinder in terms of its radius and volume, rewrite the formula as h = V/(7r²).
To rewrite the formula to solve for h in terms of r and V, we need to isolate h on one side of the equation. The given formula is V = 7r²h. To isolate h, we divide both sides of the equation by 7r². This gives us the formula: h = V/(7r²). This formula allows us to calculate the height of a cylinder given its radius and volume.
