Ron's property tax is $615.33 and is due April 5. He does not pay until July 19. The country adds a penalty of 8.4% simple inter

Number of days that attracted penalty is from April 5 to July 19 which is 105 days.

Thus the amount of simple interest attracted by Ron is given by:

$S.I.= \frac{615.33\times8.4\times105}{100\times365} = \frac{542,721.06}{36500} =\$14.87$

I have to find slope-intercept equation

adoni [48]

Answer:

y = 4x - 9

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"

The slope we can do rise over run "r/r" ot "y/x"

r/r = 4/1 = 4

The line is positive since its going up

y = 4x - 9

Hope this helped!

A marketing firm randomly sends a mass promotional mailing to 21 %of the households in a new market area. From experience the fi

coldgirl [10]

Let X be the number of households.

so they sent the promotional material to 21% which means 0.21X number of households get the material.

out of the 0.21x households only 0.14 respond which is

0.14(0.21x) = 0.0294x or 2.94%

2.94% is the probability that a household receives and responds.

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. A adult’s ticket was $6.50 while a child’s ticket was $3.50. In t

irga5000 [103]

Regal theater sold 321 adult tickets and 227 children tickets.

Step-by-step explanation:

Given,

Cost of each adult ticket = $6.50

Cost of each child's ticket = $3.50

Total tickets sold = 548

Total worth of sold tickets = $2881

Let,

x represent the number of adult tickets sold

y represent the number of child tickets sold

According to given statement;

x+y=548 Eqn 1

6.50x+3.50y=2881 Eqn 2

Multiplying Eqn 1 by 6.50

$6.50(x+y=548)\\6.50x+6.50y=3562\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(6.50x+6.50y)-(6.50x-3.50y)=3562-2881\\6.50x+6.50y-6.50x-3.50y=681\\3y=681$

Dividing both sides by 3

$\frac{3y}{3}=\frac{681}{3}\\y=227$

Putting y=227 in Eqn 1

$x+227=548\\x=548-227\\x=321$

Regal theater sold 321 adult tickets and 227 children tickets.
