Answer:

11/20

Step-by-step explanation:

It is appropriate to "invert and multiply".

$\dfrac{5}{20}\div\dfrac{5}{11}=\dfrac{5}{20}\times\dfrac{11}{5}=\dfrac{5\times11}{5\times20}=\boxed{\dfrac{11}{20}}$

I don't know if you've learnt this, but there's something called the KFC rule (you use it when dividing fractions), so k basically stands for keep (so you keep the first fraction), f stands for flip (so you flip the second fraction) and c stand for change (you change the division sign to a multiplication sign)

So you get

5/20*11/5

55/100

which is 11/20

so, an answer of 11/20 would make Quintin correct

Write the linear equation is slope intercept form 5x-y=1/4

Lana71 [14]

Slope intercept form of a line is y=mx+b where m= slope and b=y-intercept.

So, we need to convert the given equation in this form. For that simply solve the equation for y.

$5x-y=\frac{1}{4}$

$-y=-5x+\frac{1}{4}$ Subtract 5x from each sides.

$y=5x-\frac{1}{4}$ Multiply each sides by -1.

So, slope intercept frm is $y=5x-\frac{1}{4}$

Answer:

Answer is given below with explanations.

Step-by-step explanation:

$by \: simplifying \: the \: given \: expression \: using \: \\ law \: of \: exponents \: we \: get \\ \frac{15 {x}^{15} {y}^{ - 3} {z}^{4} }{18 {x}^{18} { {y}^{4} {z}^{ - 4} }^{} } \\ = \frac{5 \: {x}^{ - 3} {y}^{ - 7} {z}^{8} }{6} \\ we \: may \: also \: write \: as \\ = \frac{5 {z}^{8} }{6 {x}^{3} {y}^{7} }$

$formulae \: used \ \: : \\ \frac{ {x}^{m} }{ { {x}^{n} }^{} } = {x}^{m - n} \: \: \: and \\ {x}^{ - m} = \frac{1}{ {x}^{m} }$

2/3 divided by 1/4 HELP ME PLEASEEE

kap26 [50]

Answer: 2 and 2/3

Step-by-step explanation: In this problem, we have 2/3 ÷ 1/4.

Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the divison sign to multiplication and flip the second fraction.

So here, 2/3 ÷ 1/4 can be rewritten as 2/3 × 4/1.

Now we are simply multiplying fractions so we multiply across the numerators or top number number and multiply across the denominators or bottom numbers.

$\frac{2}{3} x \frac{4}{1} = \frac{8}{3}$

8/3 can be converted into a mixed number by dividing the denominator of the fraction into the numerator of the fraction.

3 divides into 8 2 with a remainder of 2 times so our whole number will be 2 and our new numerator will be 2 as well. We will put this over our original denominator which is 3. Now we have 2 and 2/3.

Complete the statement. Round to the nearest hundredth if necessary. 54 in.= yd.

klio [65]

A-1.5 yards

We can figure this out by using the formula of inches to yards. Which is divide by 36 so 54/36 is 1.5. So that is how the answer is solved.

I hope this helps!

"Find the value of the derivative (if it exists) at each indicated extremum. (If an answer does not exist, enter DNE.) f (x) = c

Oliga [24]

$\bf f(x)=cos\left( \frac{\pi x}{2} \right)\implies \cfrac{df}{dx}=\stackrel{chain~rule}{-sin\left( \frac{\pi x}{2} \right)\cdot \frac{\pi }{2}}$

now, what is the value of the derivative at any extrema on the original function? well, by definition, if the original function has an extrema anywhere, the derivative will be the derivative of a horizontal tangent line to it, and by definition it'll be 0.
