Answer:
30x + 80y - 15z
Step-by-step explanation:
she earns 30 points for each fish caught; if she catches x fish = 30x
80 points for each octopus captured; y octopi = 80y
but she loses 15 points every time she captures a crab; and z crabs = - 15z
The expression is given as;
30x + 80y - 15z
95 (x + y minus z) - Incorrect
10 (x + y) minus 15 z - Incorrect
30 x + 80 y minus 15 z - Correct
30 + x + 80 + y minus 15 + z - Incorrect
Answer:
1. 112 degrees = d 1.95 units clockwise
2.57 degrees = a 0.99 units
3. -133 degrees = b 2.32 units clockwise
4. 215 degrees = c (-0.82, -0.57)
Step-by-step explanation: I guessed on most of them by just looking at the unit circle and proof of their accurracy: just finished the edge practice.
Answer:
The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.
The percentage change (an increase) wa 40%.

Answer:
56cm^3
Step-by-step explanation:
Split the shape into a triangle and a rectangle
Area of triangle = half base X height
=half of 4X(6-2=4)=8 8X2=16
The volume of the triangle is 16
4X5X2=40 40+16=56
