A computer can execute 36 instructions per microsecond. How many instructions can it execute in 4 minutes?

I have no clue how to do this one, because I don't know how much is a microsecond. I need help please! Thanks!


36 x instructions over micro. sec x 1,000,000 x micro. sec over sec. x 60 x sec. over min. x 4 min.'s over 1 = 8,640,000,000

How would you do this problem?

30% of the Beads in a jar are red. The rest are blue. If here are 500 more blue beads thatn red, how many beads are there altogether?

To solve this problem, we can set up an equation based on the given information.

Let's assume the total number of beads in the jar is represented by the variable "x".

According to the problem, 30% of the beads are red. Therefore, the number of red beads is 0.3x.

The rest of the beads are blue, which means 100% - 30% = 70% of the beads are blue. So, the number of blue beads is 0.7x.

Given that there are 500 more blue beads than red beads, we can write the equation:

0.7x - 0.3x = 500

Simplifying the equation:

0.4x = 500

To solve for x, divide both sides of the equation by 0.4:

x = 500 / 0.4

Calculating this, we find:

x = 1250

Therefore, there are 1250 beads altogether.
