A bacteria culture doubles twice a day. There are 143,622 bacteria present on day 15. How many were present on day 10?
gtnhenbr [62]

Answer:

140

Step-by-step explanation:

- 143,622 bacteria present on day 15

- the bacteria doubles twice a day

that means each day backwards, the bacteria is four times less the day before

therefore:

- on day 14, the number of bacteria is 143,622 / 4

which is 35,905.5

and so on!

so:

- day 13 = 8,976.375

- day 12 = 2,244.09375

- day 11 =  561.0234375

- day 10 = 140.255859375

this rounded to the nearest whole number is

= 140 bacteria

(you can't have a part of a bacteria!)

hope this helps! :)

Jacob decided to ride his bicycle across the country during his 2-month summer vacation. the route he took from washington, dc t
Artist 52 [7]

Step 1: Assign variable for the unknown that we need to find.

Let ' x ' be the number of miles traveled by Jacob so far (His distance from starting point)

Step 2: Use the sentence given to set up an equation

Sentence 1: "His distance from his starting point was exactly 100 miles more than three times the distance remaining until the finishing point"

Total distance is 2800 miles, if his distance from the starting point is 'x', then remaining distance can be represented by 2800 - x.

Using the sentence we can write the below equation...

x = 100 + 3(2800 - x)

Distributing 3 in the right side of the equation, we get...

x = 100 + 8400 - 3x

Adding 3x on both sides of the equation, we get...

x+3x = 8500

Combine like terms in the left side of the equation, we get...

4x=8500

Dividing 4 on both sides of the equation, we get...

\frac{4x}{4} =\frac{8500}{4}

Simplifying the fraction on either side of the equation, we get...

x=2125miles

Conclusion:

Out of the 2800 miles, Jacob travelled a distance of 2125 miles and remaining miles that he need to cover will be <u>675 miles</u>.
