⦁ A total of 640 people voted in an election. The circle graph shows the results. ⦁ How many people voted for Goron? Show your w

Bezzdna [24]

Circle graphs or pie charts are used to represent data in percentages or proportions

192 voted for Goron
288 voted for Smith or Fishman

<h3>People that voted for Goron</h3>

The total number of votes is given as:

Total = 640

The circle chart is not given.

So, we make use of an assumed value

Assume 30% voted for Goron

The number of people would be:

Goron = 30% * 640

Evaluate

Goron = 192

Hence, 192 voted for Goron using the assumed value

<h3>People that voted for Smith or Fishman</h3>

Assume 45% voted for Smith or Fishman

The number of people would be:

Smith or Fishman = 45% * 640

Evaluate

Smith or Fishman = 288

Hence, 288 voted for Smith or Fishman using the assumed value

the price of an article is Marked 25% above the cost price .if it is solid the profit of Rs.500 after allowing 15% discount .wha

gavmur [86]

Answer:

Rs 8500

Step-by-step explanation:

For a cost price of c, the marked price is ...

marked = c +25%·c = 1.25c

After the 15% discount, the sale price will be ...

s = marked -15%·marked = 0.85·marked = (0.85)(1.25c) = 1.0625c

The profit will be the difference between the sale price s and the cost c:

p = s -c

500 = (1.0625c) -c = 0.0625c

Then the cost is ...

500/0.0625 = c = 8000

and the sale price is ...

s = c +p = 8000 +500 = 8500 . . . rupees

The selling price will be Rs 8500.

The tables represent two linear functions in a system,

Alenkasestr [34]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

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

First table:

(-4, 26), (0, 10) → b = 10

$m=\dfrac{10-26}{0-(-4)}=\dfrac{-16}{4}=-4$

$\boxed{y=-4x+10}$

Second table:

(-4, 14), (0, 2) → b = 2

$m=\dfrac{2-14}{0-(-4)}=\dfrac{-12}{4}=-3$

$\boxed{y=-3x+2}$

We have the system of equations:

$\left\{\begin{array}{ccc}y=-4x+10&(1)\\y=-3x+2&(2)\end{array}\right\\\\\text{Put (1) to (2):}\\\\-4x+10=-3x+2\qquad\text{subtract 10 from both sides}\\-4x=-3x-8\qquad\text{add 3x to both sides}\\-x=-8\qquad\text{change the signs}\\x=8\\\\\text{Put the value of x to (2):}\\\\y=-3(8)+2\\y=-24+2\\y=-22$
