Alenkinab [10]

Answer:

resistance: (2r +5)
current: (3i +4)

Step-by-step explanation:

The factors of the given expression are ...

6ir +15i +8r +20 = (3i +4)(2r +5)

Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...

resistance: (2r +5)

current: (3i +4)

I am a part of a whole I am greater than 3/4 but less than 9/10. I am a decimal with 3 in the hundredths place. What number am I

Alborosie

Answer:

"You" are 0.83.

(Alternative fraction version: 83/100)

Step-by-step explanation:

First, let's turn 3/4 and 9/10 into decimals.

3/4 becomes 0.75, and 9/10 becomes 0.9.

We know that it has to be a decimal, and we also know it must be greater than 0.75 but less that 0.9.

It can't be 0.73, since that's less than 0.75. It also can't be 0.93, since that's over 0.9. That means we're left with 0.83.

Our final answer is 0.83, AKA 83/100.
