Shana took a test with 50 questions. She lost 2 points for each of the 5 questions she got wrong. She got all 3 extra credit que

jeka57 [31]

Answer:

She gained 5 points in overall

Step-by-step explanation:

Shana lost points for each wrong question = 2

So, She lost points for 5 wrong questions = $2 \times 5$

She lost points for 5 wrong questions = 10 points

Now, She gained points for each correct question = 5

So, She gained points for 3 correct questions = $5 \times 3$

She gained points for 3 correct questions =15

So, Overall gain = 15-10 = 5

She gained 5 points in overall

Hence the total number of points gained by her is 5 points

Peter leaves his house and walks 15 meters south, then turns east and walks another 15 meters. How far is he from his house? Rou

Varvara68 [4.7K]

When Peter does this, he is creating two sides of a right-angle triangle. The distance from his house to that point will be the hypotenuse of the triangle thus, to work out the length of the hypotenuse, we have to use Pythagoras Theorem! So:

a² + b² = c²
15² + 15² = c²
225 + 225 = c²
450 = c²
15√2 = c
21.21320344 = c

So, this rounded to the nearest tenth would be:

21.2 meters !

If a person who works 40 hours per week earns $52,000 per year, estimate that person’s hourly wage. Use the estimate that there

oksano4ka [1.4K]

The hourly wage is approximately $26 per hour. Find out how many hours the person works per year by multiplying 40 x 50 to get 2,000 hours. Then divide 52,000 by 2,000 to get the person's hourly wage, which is $26 hours per hour.
