Mathematics
1 answer:
Natalija [7]3 years ago
5 0

A percentage is a way to describe a part of a whole. The percentage of 4c that is equal to 0.04c is 1%.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The percentage of 4c that is equal to 0.04c can be found as,

x% of 4c = 0.04

(x/100) × 4c = 0.04

x = \dfrac{0.04c \times 100}{4c}

x = 1%

Hence, the percentage of 4c that is equal to 0.04c is 1%.

If you were to write the equation of this line in the form y=mx+c what is the value of m
marusya05 [52]

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

m =  \frac{dy}{dx}

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

m =  \frac{y_2 - y_1}{x_2 - x_1}

m =  \frac{1 - 0}{0 - 4}  \\ m =  \frac{1}{ - 4}  \\ m =  -  \frac{1}{4}

Therefore the value of m is - 1/4

(y + 4 / 2y) + (y-2 / 3) = (3y^2 + 10 / 6y) for y<br>{-2, 1}<br>{-2, 3}<br>{}
vaieri [72.5K]

Answer:

{-2, 1}

Step-by-step explanation:

\frac{y+4}{2y} +\frac{y-2}{3} =\frac{3y^2+10}{6y}

Make the fractions have a common denominator.

\frac{3}{3} (\frac{y+4}{2y}) +\frac{x}{y} (\frac{y-2}{3}) =\frac{3y^2+10}{6y}\\\frac{3y+12}{6y} +\frac{2y^2-4y}{6y} =\frac{3y^2+10}{6y}\\\frac{2y^2-y+12}{6y} =\frac{3y^2+10}{6y}

Now that both sides of the equation have a common denominator, you can cancel out the denominators.

2y^2-y+12=3y^2+10

Now, set the equation equal to zero and factor.

2y^2-y+12=3y^2+10\\-y^2-y+2=0\\(-y-2)(y-1)=0\\\\-y-2=0\\y=2\\\\y-1=0\\y=-1

The y-values are {-2, 1}

(-4+2i)(7-2i) <br> Anyone know how to do this??
avanturin [10]

Answer:

<h2>-24 + 22i</h2>

Step-by-step explanation:

Use the FOIL method of multiplication of binomials:

(-4+2i)(7-2i) = -28 + 14i + 8i - (-4)i²

Note that i² = -1.  Thus, - (-4)i² = +4, and we then have:

-28 + 22i + 4, or

-24 + 22i
