The answer is A
a. first you subtract 11 from 15 to get 4
b. then you find the LCM of 12 and 8 which is 24
c. divide 24 by 12 and multiply by 5=10
d. divide 24 by 8 and multiply by 1=3
e. subtract your answer in d. from c. = 10-3=7
your answer in e over your LCM
your final answer =option A

Here is your first answer: First find the multiple which is 24 12*2=24 and 8*3=24 (denominator is 24) 5*2=10 and 1*3=3 then subtract 10-3=7 Then subtract the whole numbers 15-11=4 Your first answer is 4 7/24 or A. Here is your second answer: First find the multiple which is 80 8*10=80 and 10*8=80 (denominator is 80) 5*10=50 and 3*8=24 then subtract 50-24=26 26/2=13 and 80/2=40 Your answer is 13/40 or A

7/8
3/4
I'm order for them to have the same denominator you need to multiply so:
¾×2=6/8
So she drank 6/8 pints of water

omeli [17]

Answer:

36 ft

Step-by-step explanation:

The pole's shadow is 6 times the length of the man's shadow, so the pole is 6 times as high as the man.

6 × 5'11" = 30'66" = 35'6" ≈ 36 ft

IMPORTANT <br><br>[how do you]Find sin theta if tan theta = 3/4

zvonat [6]

$\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{4}}\impliedby \textit{let's find the \underline{hypotenuse}}
\\\\\\
\textit{using the pythagorean theorem}\\\\
c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}
\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
c=\sqrt{3^2+4^2}\implies c=5
\\\\\\
sin(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{hypotenuse}{5}}$

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
