Answer:

The probability of given event = (1)/(15)

Step-by-step explanation:

Ten slips of paper labeled from 1 to 10 are placed in a hat. The first slip of paper is not replaced before selecting the second slip of paper.

We have to find the probability of selecting a number less than 3 and then a number greater than 4.

Probability of an event = (number of favourable events)/(total number of events)

The probability of selecting number less than 3 = (2)/(10) = (1)/(5)

The probability of selecting number greater than 4 = (3)/(9) = (1)/(3)

Total probability = (1)/(5)* (1)/(3) = (1)/(15)

You can Drive your car 21.75 miles with 1 gallon of gasoline how many miles can you drive with 13.2 miles of gasoline

Answers

21.75miles=1gallon
xmiles=13.2gallons
easy, multiply the first equaiton by 13.2 to get the galons to match

21.75*13.2=287.1 miles=13.2 gallons
answer is 287.1 miles
You can drive 287.1 miles with 13.2 miles of gasoline

Hot Air Balloon 1 is 10 meters above the ground, rising 15 meters per minute, and Hot Air Balloon 2 is 150 meters above the ground descending 20 meters per minute. In how many minutes will the balloons be at the same height?
How high will the balloons be at that time?
(Let x represent the time and y represent the height)

Answers

The time at which the ballons are at the same height is 4 minutes and the height of the ballons at that time is 70 meters and this can be determined by using the given data.

Given :

  • Hot Air Balloon 1 is 10 meters above the ground, rising 15 meters per minute.
  • Hot Air Balloon 2 is 150 meters above the ground descending 20 meters per minute.

The following steps can be used in order to determine the time in minutes at which the balloons be at the same height and also the height of the ballons:

Step 1 - The height of balloon 1 from the ground is:

H_1= 10+15t

where 't' is the time.

Step 2 - The height of balloon 2 from the ground is:

H_2= 150-20t

where 't' is the time.

Step 3 - So, the time at which the ballons are at the same height is calculated as:

\begin{aligned}\n15t +10&=150-20t\n35t &= 140\nt& = 4\;{\rm minutes}\n\end{aligned}

Step 4 - So, the height of the ballons at (t = 4) is:

{\rm Height} = 10+15* (4)

{\rm Height} = 70\;{\rm meters}

The time at which the ballons are at the same height is 4 minutes and the height of the ballons at that time is 70 meters.

You have two equations
y = 10 + 15x   and    y = 150 - 20x
since  y = y   you can get
10 + 15x = 150 - 20x    now we solve for x
      +20x         +20x     add 20x to both sides
10 + 35x = 150    now subtract 10 from both sides
-10             -10
35x = 140    then divide both sides by 35
/35      /35
so  x = 4 minutes

to find what high they are at 4 minutes
plug 4 back into the equation for x
y = 10 + 15(4) = 10 + 60 = 70
so  70 meters from the ground
