Answer:

D -24/25

Step-by-step explanation:

sin²(x) = 1 - cos²(x) = 1 - (⅘)²

sin²(x) = 9/25

sin(x) = -⅗

(Because 4th quadrant)

sin(2x) = 2(-⅗)(⅘)

= -24/25

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
