Answer:

Approximately 23,433 children will have cancer.

Step-by-step explanation:

3/1500 can be simplified to 1/500, which can also be written as 0.002. To find the number of children who have cancer, we do 11,721,722 * 0.002, which gives us 23,433.444 which we can round to 23,433.

(1−(−x/3))

1/(3+x)=(1/3)1(1−(−x/3))

Use this fact that

last weeekend trisha and becca both went on a bike ride trisha biked 8 miles in two hours and becca biked 10 kilometers in 7800

S_A_V [24]

So first I’m going to change the 10 kilometre in miles which is 6.214 miles
Then I’m going to convert 7800 seconds in hours which is 2.16 hours so now the data shows that Trisha biked 8 miles in 2 hours and becca biked 6.214 miles in 2.16 hours
So Trisha was faster than becca

Determine the average speed of the current in a river if a boat moves at 20 miles/hour in still water and takes 3 hours to trave

Taya2010 [7]

The speed of the current in a river is 6 miles per hour

Solution:

Given that,

Speed of boat in still water = 20 miles per hour

Time taken = 3 hours

Distance downstream = 78 miles

To find: Speed of current

If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

Speed downstream = (u + v) km/hr

Speed upstream = (u - v) km/hr

Therefore, speed downstream is given as:

$\text{ speed downstream } = \frac{distance}{time} = \frac{78}{3}\\\\\text{ speed downstream } = 26 \text{ miles per hour }$

We know that,

Speed downstream = (u + v)

26 = 20 + v

v = 26 - 20

v = 6 miles per hour

Thus speed of the current in a river is 6 miles per hour
