Answer:

93.5 mm

Step-by-step explanation:

1. Add all the rainfall readings together to find the total rainfall.

12.48+8.82+27.51+44.73=93.54

2. One decimal place means you'll be rounding 93.54 to the nearest tenth. Round down if the decimal place immediately to the right is less than 5, round up if it is greater than or equal to 5. Since 4 is the value in the hundredths place and 4<5, we are going to round down.

3. The answer is 93.5 mm, don't forget your units.

Hope you found this helpful, have a nice day.

A computer chip manufacturer made 270,000 chips last week. If 8% of them were defective, how many defective chips were made?

Alina [70]

Number of defective chips = 8% of 270,000

= $\frac{8}{100}$ x 270000

= 8 x 2700

= 21,600

Thus, 21,600 defective chips were made.

I hope this answer helps! If you have any doubts, feel free to ask!

Answer:

$cos{\frac{2\pi}{3}}=-\frac{1}{2}$ .

Reference angle is $\frac{\pi}{3}$

Step-by-step explanation:

Given the value of x. we have to find the correct value of cosx.

$x=\frac{2\pi}{3}$

Now, we have to find the exact value of $cos{\frac{2\pi}{3}}$

$cos{\frac{2\pi}{3}}=cos(\frac{\pi}{2}+\frac{\pi}{6})$

$=-sin(\frac{\pi}{6})$

$=-\frac{1}{2}$

Now, we have to find the reference angle of $x=\frac{2\pi}{3}$ .

Since the angle $x=\frac{2\pi}{3}$ lies in second quadrant, the reference angle formula is

Reference angle= $\pi-given angle$ .

= $\pi-\frac{2\pi}{3}=\frac{\pi}{3}$
