What is the value of x?<br><br> A. 4<br><br> B. 4√3<br><br> C. 8<br><br> D. 8√3
SashulF [63]

Answer:

B. 4√3

Step-by-step explanation:

\sin \: 60 \degree =  \frac{x}{8}  \\  \\  \therefore \:  \frac{ \sqrt{3} }{2}  = \frac{x}{8} \\  \\  \therefore \: x =  \frac{8 \times  \sqrt{3} }{2} \\  \\  \therefore \: x =  4 \times  \sqrt{3}\\  \\  \huge \purple{ \boxed{ \therefore \: x =  4 \sqrt{3} }}\\

Can a -150/10 be classified as both a rational number and a integer
irakobra [83]
Yes! This is because -150/10 can be simplified to be -15, which is a rational number.

The word “rational” sounds like another math word you’ve heard of before. Do you know what it is?

Well, it’s “ratio”!! Ratios can be seen in the forms x:y and x/y.


ANY RATIONAL NUMBER HAS THE ABILITY TO BE WRITTEN AS A RATIO!! This will completely exclude numbers with super long decimal points (ex: 1.2345678809928374737272828...)

This number also meets the requirements of being an integer. An integer is any whole number (this excludes decimals and fractions)

I know it’s written as a fraction. However, the fraction could be simplified, making it -15, which means this is both a rational number and an integer!!

I need the answer for 90 please its due tommorow!
babunello [35]
Jacqueline is incorrect. 
To find how much trash you can clean in 4 days if you already know how much trash you can clean in one day, multiply 1 2/3 (how much you can clean in one day) by 4. 
Another way to write 1 and 2/3 miles is 5/3 (converting a mixed number to a single fraction). Then, 5/3 x 4 = 20/3. (To multiply fractions, just multiply across, leaving 5 x 4 in the numerator and 4 x 1 in the denominator.)
Jacqueline said you would be able to clean 19/3 miles but you can actually clean 20/3.
