Answer:

The Tasty Beans Coffee House being planned for the corner of SE 12th and Main will ruin a perfectly nice neighborhood. Besides the fact that Tasty Beans already has coffee shops all over the city, it will pull business away from local coffee houses that have been here for decades. In addition, there is already a parking problem on that street, and the new business will just add to the congestion. They're planning a drive-up window, too, and that will mean a steady stream of traffic in a very high-volume area. Ask anyone walking down the street, and they'll tell you this is a bad idea. I speak for my whole neighborhood when I say, "Go away, Tasty Beans!"

Answer: 40\ beats

Step-by-step explanation:

Knowing the information provided in the exercise, you need to find the Least Common Multiple (L.C.M) in order to solve it.

You can follow these steps:

1- You must descompose 2, 5 and 8 into their prime factors:

2=2\\5=5\\8=2*2*2=2^3

2- And finally, you must multiply the commons and non commons with the highest exponent:

L.C.M=2^3*5=40

Therefore, the answer is: 40\ beats

4. Which of the following indicates the multiplication property of equality when solving Vz= 5?
tiny-mole [99]

Answer:

D. 21.

Step-by-step explanation:

The general form of the equation of a circle is:

(x - a)^2 + (y - b)^2 = r^2  where r is the radius.

Comparing:

(x + 5)^2 + (y + 7)^2 = 21^2

So r^2 = 21^2

making r = √21^2

= 21.
