a marrow plants 0.5 m long. every week it grows by 20%. a find the value of the common ratio. b calculate how long the plant is
OLga [1]

Answer:

The common ratio is 1.2.

After 12 weeks the plant will be 4.46 meters long.

After one year the plant will be 6,552.32 meters long.

Step-by-step explanation:

Given that a marrow plants 0.5 m long and every week it grows by 20%, to find the value of the common ratio, calculate how long the plant is after 12 weeks and comment on the predicted length of the marrow after one year must be performed the following calculations:

0.50 x 1.2 ^ X = Y

Therefore, the common ratio is 1.2.

0.50 x 1.2 ^ 12 = Y

0.50 x 8.916 = Y

4.4580 = Y

Therefore, after 12 weeks the plant will be 4.46 meters long.

0.50 x 1.2 ^ 52 = Y

0.50 x 13,104.63 = Y

6,552.32 = Y

Therefore, after one year the plant will be 6,552.32 meters long.

<u>Let's take this problem step-by-step:</u>

 

<u>First let's set up the equation for the cost for one week of renting the car</u>

  • agency charges $230 per week

              charge = 230

  • agency charges $0.25 per mile (<em>lets set the number of miles as 'x')</em>

<em>               </em>charge = 230 + 0.25x

<u>The total cost was 415</u>, <em>therefore:</em>

             415 =230 + 0.25x\\185 = 0.25x\\x = 740

Therefore, you traveled 740 miles

<u>Answer: 740 miles</u>

<u></u>

Hope that helps!
