26+3+11=40
42-40=2
He has 2 minutes left
Answer:
3(7j + 2 + 4j)
Step-by-step explanation:
We have to write an expression that looks like Sarah’s expression: 5(2j + 3 + j). We habr Replace the coefficients so that our expression is not equivalent. Also We may use any number that we choose to replace the coefficients ensuring to leave the variables the same.
Example, 3(7j + 2 + 4j) looks like Sarah’s expression but is not equivalent.
Cos (theta) would be equal to 15/-1!
The reason is because the inverse of sin is equal to the hypotenuse over the opposite angle, meaning the hypotenuse would be -1. Tan is equal to the opposite over the adjacent angle, meaning the adjacent angle equals 15. Cos is equal to the adjacent over the hypotenuse, making cos (theta)= 15/-1!
To find 1/10 of a number you need (1/10)*number, or number/10
number/10=0.0003
number=0.0003*10=0.003
