If there was a total of 30 computers and the computer lab is removing 3 broken computers and adding 13 wireless devices, about w
Liula [17]

32.5 % of lab are wireless devices

<em><u>Solution:</u></em>

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

<em><u>To find: what percent of the lab are wireless devices</u></em>

So we have to find what percent of 40 is 13

Let "a" be the required percent

a % of 40 = 13

\frac{a}{100} \times 40 = 13\\\\a = \frac{13 \times 100}{40}\\\\a = 32.5

32.5 % of of lab are wireless devices

Eduardo’s average speed on his commute to work was 55 miles per hour. On the way home, he hit traffic and only averaged 40 miles
alekssr [168]

Answer:

40(1.25-t)

Step-by-step explanation:

There are 3 components to consider; time, speed and distance

Time and Speed are given.

The distance has to be calculated.

  • Speed to work = 55 miles per hour
  • Time to work = 1.25-T
  • Speed to home = 40 miles per hour
  • Time to home = 1.25-t
  • Total Time = T + t = 1.25

<u>Distance for trip to home</u>

Speed = Distance/Time

40 = Total Distance/1.25-t

Total Distance = 40(1.25-t)

<em>Therefore, 40(1.25-t) is the correct answer.</em>

Explain how you would convert a measurement given in ounces in pints
Tom [10]

Answer:

It is known that 1 pint equals 16 ounces

Step-by-step explanation:

It is known that 1 pint equals 16 ounces. Then we use this data to transform a number of ounces into pints.

Suppose we have x ounces. We want to know how many pints are these x ounces. Then we perform the following operation

x\ ounces*\frac{1\ pint}{16\ ounces}=z\ pints

Where z pints is the amount equivalent to x ounces

In 12 years, Janice will be 8 times as old as she was 2 years ago. How old is Janice<br> now?
Setler [38]

Janice is currently 4.

In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.

I hope this helps!
