Harman [31]

Answer:

2.4 hours

Step-by-step explanation:

Because 1 hour Randy clean 1/4 of the room and Trey is 1/6. So we add both together and get that they clean 5/12 of the office in one hour. So 2.4 hours is the greatest amount of time it would take them to clean offices together

HELP PLEASE 30 POINTS! WILL MARK BRAINLIEST IF CORRECT!!!!!
KATRIN_1 [288]

Answer:

See Below.

Step-by-step explanation:

We want to verify:

\cos(x-y)-\cos(x+y)=2\sin(x)\sin(y)

We will utilize the following identities:

\cos(x-y)=\cos(x)\cos(y)+\sin(x)\sin(y)

And:

\cos(x+y)=\cos(x)\cos(y)-\sin(x)\sin(y)

So, by substitution, we acquire:

(\cos(x)\cos(y)+\sin(x)\sin(y))-(\cos(x)\cos(y)-\sin(x)\sin(y))=2\sin(x)\sin(y)

Distribute:

\cos(x)\cos(y)+\sin(x)\sin(y)-\cos(x)\cos(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)

The first and third term will cancel:

\sin(x)\sin(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)

Combine like terms:

2\sin(x)\sin(y)\stackrel{\checkmark}{=}2\sin(x)\sin(y)

Which of the following numbers is the smallest 0.008 or 1/3 or 0.048 or 0.36 or 1/9
RideAnS [48]

Answer:

The smallest number is 0.008

Step-by-step explanation:

To find out which number is the smallest we convert the decimals to percentages

That's

0.008 × 100= 0.8%

1/3 × 100 = 33.3%

0.048 × 100 = 4.8%

0.36 × 100 = 36%

1/9 × 100 = 11.1%

Comparing from the above percentages the smallest one is 0.8% which is

0.008.

Hope this helps you.
