Answer:

A&C

Step-by-step explanation:

As, you said, the first answer is C. Now, we are given seven, and when we are adding a negative number, we move in the direction of left, and since we are moving by 7, we would be moving 7 to the left. Therefore, the other answer is A.

I think it’s b but I’m not sure

No, its D

Just look at the rounds mentioned and subtract the scores from higher round with lower round.

Look at A: round 2 score - round 1 score = -2?
-3 -1 = -4 change, not -2 change so it is wrong

Look at B: round 3 score - round 1 score =-1?
-2-1 =-3 change, not -1 change so it is wrong

Look at C: round 3 score - round 2 score =-1?
-2 -(-3) = 1 change, not -1 change so it is wrong

Look at D: round 3 score - round 1 score =-3?
-2-1 = -3 change, matches with -3 so it is correct.

Dans computer reads 68% of battery left after 1 hour. If the rate of using power remains the same, about how much longer will hi

Tanya [424]

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:

$\frac{1}{x} * 100 = 68$

Therefore:

$\frac{100}{x} = 68\\\\x = \frac{100}{68}$

=> 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.

Need help with question 15

GarryVolchara [31]

Answer:

$k=110$

Step-by-step explanation:

Part 15) we know that

$n=klog(A)$

Solve for k

That means ----> isolate the variable k

$k=n/log(A)$

we have

$n=440\ wolves$

$A=10,000\ mi^{2}$

substitute

$k=440/log(10,000)$

$k=110$
