How do you divide fractions?
Zanzabum
2/8 divided by 1/4. Steps: 1. Division in math actually means multiplication. You just have to multiply by the reciprocal of the second fraction (reciprocal= denominator and numerator are switched). 2. Do 2/8 times 4/1. 3. 2 times 4= 8 and 8 times 1= 8 4. Your answer would be 8/8 which equals 1. This is how you divide fractions

The regular price of a pair of sneakers is $65. They are on sale for 20% off. What is the sale price?
Fofino [41]
65*0.20=13 (0.20 because 20/100=20% is 0.20 in decimal form)
65-13=52

The line of best fit for a scatter plot is shown:
alex41 [277]
In the slope intercept form, b represents the y intercept.
y = mx +- b

Therefore, if the y intercept is at 6, the formula of the line will look like
<span>y=mx + 6
</span>
This eliminates the first two options, 
y = -6x + \frac{3}{4} &#10;
and
y=6x +  \frac{3}{4}

and leaves behind
y= - \frac{3}{4}  +6
and
y= \frac{3}{4} x+6

Since the line you indicated is sloping downwards towards the lower right hand corner. It must have a negative slope.

Therefore, the answer must be the 3rd option.

<span>y= - \frac{3}{4} +6</span>

Can someone please help me ASAP.....
tester [92]

We have to start with a number x, compute f(x), and then use this result as input for g(x)

When you give x as input to f, it returns -x^2-1:

x\mapsto f(x)-x^2-1

Now, g(x)=x+5 simply means that g will return its input plus five.

In this case, the input is f(x), so we have

g(f(x))=f(x)+5 = -x^2-1+5=-x^2+4

In a circle, area and circumference can be found using the formulas A=(pi)r^2 and C=2(pi)r, respectively, Write a formula for A
AURORKA [14]

Answer:

A = \dfrac{C^2}{4\pi}

Step-by-step explanation:

Given that

Area of a circle A=\pi r^2

Circumference of the circle C = 2 \pi r

Let us re-write the equation of area of circle:

A=\pi r^2

A = \pi \times r \times r

Multiplying and dividing with 2:

A = \dfrac{2\pi r}{2} \times r\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C}{2} \times r\\\text{Multiplying and dividing by } 2\pi:\\\Rightarrow A = \dfrac{C}{2} \times \dfrac{2\pi r}{2\pi}\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C \times C}{4 \pi}\\\Rightarrow A = \dfrac{C^2}{4 \pi}

Hence, <em>A</em> in terms of <em>C</em> can be represented as:

A = \dfrac{C^2}{4\pi}
