It would take her around 37 minutes, I divided 486 by 195 and got 2.5, basically. I then timed that by 15 and got 37
Answer:
30%
Step-by-step explanation:
To calculate the percentage of deliveries that Lamar has completed so far, divide the number of deliveries so far by the total number he needs to make.
21/70 = 0.3
Convert the decimal to percentage form by moving the decimal two places to the right and including the percent sign.
0.3 = 30%
He has completed 30% of his deliveries.
The number of complex roots is 2 or 0
Answer:
no solution
Step-by-step explanation:
We can think of an absolute value as the magnitude of the number. We can also define it as how far the number is from 0 on the number line. Thus, absolute value must always be positive (or 0).
<h3>
Solve</h3>
Start by adding 1 to both sides:
![\frac{|m|}{2}=-2](https://tex.z-dn.net/?f=%5Cfrac%7B%7Cm%7C%7D%7B2%7D%3D-2)
Multiply both sides by 2:
![|m|=-4](https://tex.z-dn.net/?f=%7Cm%7C%3D-4)
The absolute value of a number is always positive (with the exception of 0), therefore there is no solution.
<h3>Additional Comments</h3>
Notice we can only add/multiply (or subtract/divide) an equation because of the Addition/Subtraction/Multiplication/Division Property of Equality which state that if you add/subtract/multiply/divide one side of the equation by a certain value, you must do the same to the other side of the equation.
P = 2*pi*sqrt(a^2 +b^2/2 =
2 *3.14 * sqrt(15/2^2 +7.5/2^2/2 =
6.28 x sqrt(56.25+14.0625/2
6.28 *sqrt(35.15625)
6.28 * 5.929270613= 37.235
answer is B 37.3 feet
