Answer:
The second table.
Step-by-step explanation:
In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43. It decreases and then increases. This is not the correct table.
In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47. It increases and then decreases; this is the correct table.
To verify, we check the last two tables. The third table stays at 45, then decreases to 43 and 41. This is not correct.
The last table decreases from 45 to 43, then decreases to 41, then stays constant. This is not correct.
The second table is the only correct one.
To determine the Earnings of Shelley last week, we need to make relations with the values that are given. We let x as the total amount she earned last week by x and y as the additional amount she earned this week We do as follows:
20% additional amount she earned this week = y / 72 - y
y = $ 12
x = 72 - 12 = $60 total earnings last week
The lengths of the sides of the triangle:
No sides are equal to each other, so it's a scalene triangle.
Check if the sides satisfy the Pythagorean theorem:
They do, so it's a right triangle.
The triangle is a
right scalene triangle.
