Let's firstly convert the mixed fractions to "improper", and then divide,

\bf \stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}}
\\\\\\
\cfrac{7}{4}\div -21\implies \cfrac{7}{4}\div \cfrac{-21}{1}\implies \cfrac{7}{4}\cdot \cfrac{1}{-21}\implies \cfrac{7}{-84}\implies \stackrel{simplified}{-\cfrac{1}{12}}

Hello!

To do this you will simply convert 3/4 to 0.75 and divide.

1.75/-21=1/12.

Our final answer is \frac{1}{12}.

I hope this helps!

What set of transformations could be applied to rectangle ABCD to create A'B'C'D'? Reflected over the x-axis and reflected over
noname [10]
<u>Answer</u>
<span>Reflected over the x-axis and reflected over the y-axis.

<u>Explanation.</u>
When the rectangle ABCD is reflected along the x-axis, the images of ABCD will be A''(-4,-2), B''(-4,-1), C''(-1,-1) and D''(-1,-2). 
When the rectangle A'', B'', C'' and D'' is reflected on the y-axis, it will exactly map on to A'B'C'D'. 

So, the correct answer from the choices is "</span><span>Reflected over the x-axis and reflected over the y-axis". </span><span>

Pls help asap!!! just need answers not work
dem82 [27]

Answer:

b= 5\sqrt{3} c = 10,   x=7 hypotenuse = 7\sqrt{2}

Step-by-step explanation:

A 30-60-90 triangle has the ratios of x-x\sqrt{3}-2x so if x=5, then 5-5\sqrt{3} - 10

for a 45-45-90, if one leg is 7, so is the other x\sqrt{2} so hypotenuse is 7\sqrt{2}
