If As income is 20% more than Bs income, how much percent is Bs income less than As income

vitfil [10]

$As\ is\ 120\%\ Bs\\\\120\%=1.2\to\frac{As}{Bs}=1.2\\\\\frac{As}{Bs}=\frac{12}{10}\to\frac{Bs}{As}=\frac{10}{12}\to\frac{Bs}{As}=\frac{5}{6}\\\\\frac{5}{6}\cdot100\%=\frac{500}{6}\%=83\frac{1}{3}\%\\\\100\%-83\frac{1}{3}\%=16\frac{2}{3}\%\\\\Answer:Bs\ income\ is\ 16\frac{2}{3}\%\ less\ than\ As\ income.$

PLEASE HELP!!<br> Factor <br> 6x^2-42x-54<br><br> Please show work!

skad [1K]

first, rewrite 54 as 6•9

next, rewrite 42 as 6•7

then, that gets you 6x^2 -6•7x- 6•9

lastly, factor out the common term (6)

and then you get 6(x^2-7x-9)

<u>please mark as brainliet <3</u>

Answer:

FC = 27, QC = 18

Step-by-step explanation:

The centroid Q is $\frac{1}{3}$ the way along CF , therefore, QF is half as long as CQ

Given FQ = 9, then

QC = 2 × 9 = 18

FC = FQ + QC = 9 + 18 = 27

Jolene is making a line graph showing that the cost of grain is proportional to the number of pounds purchased. Jolene will plot

Gelneren [198K]

Answer:

a. $(1,0.25)$

b. $y = 0.25x$

Step-by-step explanation:

Given

The data in the table

Solving (a): The coordinate that represents the unit rate

The unit rate is when its 1 pound

This is so because the unit rate is dollars per pounds.

<em>Hence, the coordinate is </em> $(1,0.25)$ <em></em>

Solving (b): Equation of the graph

First, we calculate the slope (m)

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

Where:

$(x_1,y_1) = (1,0.25)$

$(x_2,y_2) = (4,1.00)$

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

$m = \frac{1.00 - 0.25}{4 - 1}$

$m = \frac{0.75}{3}$

$m = 0.25$

The equation is then calculated as thus:

$y - y_1 = m(x - x_1)$

This gives:

$y - 0.25 = 0.25(x - 1)$

$y - 0.25 = 0.25x - 0.25$

Make y the subject

$y = 0.25x$

<em>Hence, the equation of the graph is: </em> $y = 0.25x$ <em></em>
