Anna average speed in km/h is 7.5 km per hour
<h3>Average speed</h3>
Average speed is the ratio of total distance covered to total time taken. It is given by:
Average speed = Total distance / total time
Given the distance upstream is 16 km at a rate of 6 km/h, hence:
The distance downstream is 16 km at a rate of 10 km/h, hence:
Total distance = 16 km + 16 km = 32 km
Total time = 2.67 + 1.6 = 4.27 hours
Average speed = 32 / 4.27 = 7.5 km per hour
Anna average speed in km/h is 7.5 km per hour

Let's solve this problem step-by-step.
Let's first establish the following formula:
Angle sum of a triangle = 180°
Also, note that the square shape in the top-right corner of the triangle indicates that it is a right-angle. This means that, that angle is equal to 90°.
Now, let's establish the equation we will be using to solve this problem based on the previous information as displayed below:
m + 38° + 90° = 180°
We will now simply solve the equation in order to obtain the value of ( m ) as display below:
m + 38° + 90° = 180°
m = 180 - 38 - 90
m = 52°
ANSWER:
Therefore, the answer is:
C. 52 degrees.

Answer:
Alex needs to make 10 tables per week.
Step-by-step explanation:
If his base pay is $300, then subtract it from $800, you get $500. Then divide $500 by how much Alex earns per table, $50, then you get 10. Alex needs to make 10 tables per week.
Answer:
Percentage error is 0.0024 %
Step-by-step explanation:
Initial average distance between Earth and moon = 384467 km
Distance measure by the scientist = 384476 km
Total variation in the distance calculation = 384476 – 384467 = 9 km.
Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.
Percentage error = ( 9 / 384467 ) × 100 = 0.0024 %
