Answer:

It could be $12.05.

Step-by-step explanation:

I don't really understand it but, i did 80% divided by 10 but it would be $0.08 and i don't think it would be that so i did 10 divided by 80 and it came out as $12.05.

i haven't done that in school so im not sure

Is line 1 (1,5) (3,-2) and like 2 (-3,2) (4,0) perpendicular of parallel?
Lera25 [3.4K]
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}

Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>

One year on Venus is equivalent to 224.7 days on Earth. How many days on Earth, in decimal from, are equivalent to 9 ½ years on
Ivan

By using simple rule of three, a period of 9.5 years on Venus is equivalent to 2134.65 terrestrial days.

<h3>How many terrestrial days are equivalent time in Venus?</h3>

One year on Earth is equivalent to 365.3 days and one year on Venus is equivalent to 224.7 days, the equivalent terrestrial time of 9.5 years on Venus is found by simple rule of three:

x = 9.5 yr × (224.7 days / 1 yr)

x = 2134.65 days

A period of 9.5 years on Venus is equivalent to 2134.65 terrestrial days.

A certain taxi driver charges a rate of r cents per person per mile. How much money, in dollars, would it cost three people to t
Anika [276]

Answer:

It would cost ( 3xr/200) dollars  to three people to travel x miles.

Step-by-step explanation:

Here, according to the question:

The rate of the taxi fare = r cents per person per mile

The total number of people travelling = 3 friends

Each person travels x miles.

So, the total distance traveled by 3 friends

= 3  ( Distance traveled by 1 friend) = (3 x) miles

Now, as each mile costs r cents.

So, the cost of travelling (3 x) miles  = ( 3 x) (r)  cents   .... (1)

Also, 100 cents = $ 1

So,  1 cent = (1/100) dollars

⇒ r cents  = (r/100) dollars

So, the cost of travelling (3 x) miles  = ( 3xr/100) dollars  .... (2)

Now, If he gives them a 50% DISCOUNT.

Then the cost of travelling (3 x) miles  = ( 3xr/ 2 x 100) dollars  

= ( 3xr/200) dollars  

Hence,it would cost ( 3xr/200) dollars  to three people to travel x miles.
