Prii needs to run at least 30

1 answer:

7 0

There are 3 more days
So 12 divided by 3
Which is 4, so he needs 3 more hours per day for the remaining 3 days

RECURSIVE RULE: r = 3

an = a(n - 1) × r [formula]

ANSWER: an = a(n - 1) × 3

_________________________________________

ITERIATIVE RULE: r = 3, a1 = 6

an = a1 × r^(n - 1) [formula] [ ^(n-1) is an exponent]

ANSWER: an = 6 × 3^(n - 1)

The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,

$110-2x+x+50+5x-40=180$
