The first step to solve this problem is to figure out how many countries per day ms. Sims travels. Do this by dividing 42 by 60. If the division sign is a “per” symbol she would travel 42 every 60 days.
42/60 is 0.7
So she travels 0.7 countries per day.
Multiplied by 40 days (40 times 0.7) is 28. 28 countries per 40 days
The formula for the circumference of a circle 'pi x diameter' so you need to multiply the radius shown on the circle by 2 so 15 x 2 = 30 and then you multiply this by pi using the formula: pi x 30 = 94.25 to 2 decimal places. This is the final answer. The pi symbol is π can be found on an advanced calculator :) .

Option 2:
The variable a should be multiplied by Two-thirds only and then added to 10.
Step-by-step explanation:
Let the age be a
The sum of 10 and two-thirds of that tree’s age:

is equal to 50:
10 + ⅔a = 50
⅔a = 40
a = 60
