1 and half hour
= 60 minutes+ 30 minutes

Uzanne need 15 minutes to do 10 problems
Uzanne need 1 minute to complete 10/15 problems

worty [1.4K]

Answer:

  2080

Step-by-step explanation:

The solution to these equations might best be found using Cramer's Rule. It tells you ...

  x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400

This is years after 1990, so the year the incomes become the same is predicted to be ...

  1990 +90.4 = 2080.4

The median incomes will be the same in the year 2080.

tatiyna

Answer:

136.2

Step-by-step explanation:

Plugin x = 18 in the polynomial.

P(x) = 0.02x³ + 0.04x² + 0.3x + 1.2

P(18)= 0.02*(18)³ + 0.04*(18)² + 0.3*18 + 1.2
