If there was a total of 30 computers and the computer lab is removing 3 broken computers and adding 13 wireless devices, about what percent of the lab are wireless devices

32.5 % of lab are wireless devices

Solution:

Given that there was a total of 30 computers and the computer lab is removing 3 broken computers and adding 13 wireless devices

Now we can first find out total number of computers and devices in lab

total number of computers and devices in lab = 30 computers - 3 + 13 wireless devices

total number of computers and devices in lab = 30 - 3 + 13 = 40

So there are 40 computers and wireless devices in lab

To find: what percent of the lab are wireless devices

So we have to find what percent of 40 is 13

Let "a" be the required percent

a % of 40 = 13

32.5 % of of lab are wireless devices

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
