Answer:
28 minutes
Step-by-step explanation:
Dans computer reads 68% of battery left after 1 hour. This means that 1 hour is 68% of the computer's entire battery life.
Let the entire battery life be x (in hours). Hence:

Therefore:

=> x = 1.47 hrs = 1 hr 28 minutes
Hence, the entire battery life is 1 hr 28 minutes.
If 1 hour has elapsed, the remaining time left for his battery to provide power will therefore be:
1 hr 28 minutes - 1 hr = 28 minutes
His battery will provide power for 28 more minutes.
Answer:
Insufficient Data
Step-by-step explanation:
Please correct the problem. Given details are not enough or/and precise to suggest solution
This is the eqn of a str line. <span>y+4=12/7(x-1) would be clearer if written as
</span><span>y+4=(12/7)(x-1). y+4 = (12/7)x - 12/7.
Multiply all terms by 7 to remove the fractions: 7(y+4) = 12x - 12.
Complete the multiplication: 7y + 28 = 12x - 12.
Arrange the x and y terms on the left side and the constants on the right:
-12x + 7y = -40. This is standard form. Some people might disagree and say that -12x + 7y + 40 is standard form. They are equivalent.

the base of the ladder is 18ft away from the wall
18 - [ 18 - [ 18 - ( 18 - 1)]]
= 18 - [ 18 - [ 18 - 17]]
=18 - [ 18 - 1]
= 18 -17
