My late response (haha): First, you would write a proportion.
Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).
Step 2: Cross multiply
2496 times 31 and x times 48
Step 3: Calculate
77376 = 48x
Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x
Step 5: Write it as a sentence
The area of the land that is not fenced is 1612 squared meters.
Hope that helped! Good luck! :]
Probability of an event happening is given by:
probability of an event happening=number of ways it can happen/total number of outcomes
number of random selection=40
total number of patients who did not leave against medical advice=52,560
thus the probability that at random selection none of the 40 patients left the treatment center against medical advice will be:
40/52560
=0.00076

Step-by-step explanation:
Here we are asked to find the smallest number which must be multiplied to 240 to make it a perfect square .
So , lets do prime factorisation of 240 .
Here , 240 = 2 × 120 .
= 2 × 2 × 60.
= 2 × 2 × 2 × 30.
= 2 × 2 × 2 × 2 × 3 × 5 .
Hence we got 240 = 2⁴ × 3¹ × 5¹ .
Now here we can see that , in order to make a perfect square it should be multiplied by 3 × 5 = 15 in order to make power of prime factors even .
For this case we have that by definition the time is given by:
Where the variable "d" represents the distance and "v" represents the speed.
So, first we need to know the total distance:
Then, the time for 75mph is given by:
Answer:
6,4 hours
