In this case, you need to find the percentage each student got, then find who received a higher score.

First Step: \frac{85}{95} (and) \frac{64}{76}
Second step: Divide each fraction → ≈ 0.8947 (and) ≈ 0.8421
Third Step: Multiply each decimal by 100. → 89.47% (and) 84.21%

Fourth Step: As 89.47% is greater, Author got an higher score.

50 POINTS find the length of ab plz help me
Umnica [9.8K]

Answer:

about 9.4 units

Step-by-step explanation:

Distance formula:

√(x1 - x2)² + (y2 - y1)²

Coordinates:

A (4, 2)

B (9, 10)

Let's make 9 = x1

Let's make 4 = x2

Let's make 10 = y1

Let's make 2 = y2

Substitute into the distance formula:

√(x1 - x2)² + (y2 - y1)²

√(9 - 4)² + (2 - 10)²

Solve:

√(9 - 4)² + (2 - 10)²

√(5)² + (-8)²

√25 + 64

√89

≈ 9.4

Therefore, the length of AB is approximately 9.4 units.

30 POINTS PLEASE ANSWER CORRECTLY AND CLEARLY THANK YOU!
TiliK225 [7]

Answer:

B

Step-by-step explanation:

The investment grows by 12 percent every year. Therefore, if you multiply the 1500 by 0.12 you should get the value of the amount of extra money made in one year. If you substitute 2 into t you get the value increased by year 2 and so on.

Donte is driving 838 miles to his aunt’s house. His car has a 14-gallon tank and goes 26 miles for every gallon of gasoline. Don
ipn [44]
So you first do 26 x 14 = 364 miles for 14 gallons
838 ÷ 364 = 2.302
You then have to round the number, and because you can't stop 0.302 times, the answer is 3.
... I think, someone might need to double check me

8^x+3=16^x−1<br> solve the exponential equation ...?
Juli2301 [7.4K]
Let us write down the equation clearly and in a proper manner. This will help in solving the equation very easily.

8^(x + 3) = 16^(x - 1)
(2^3)^(x + 3) = (2^4)^(x - 1)
(2)^3(x + 3) = (2)^4(x - 1)
Then
3(x + 3) = 4(x - 1)
3x + 9 = 4x - 4
4x - 3x = 9 + 4
x = 13

I hope the procedure is clear enough for you to understand. I also hope that this is the answer that has actually come to your desired help.
