Answer:
One hundred and fifty 40 pounds boxes and twenty 75 pounds boxes
Step-by-step explaination:
The maximum amount he can haul in one load is 7500 pounds
150 × 40 pounds boxes = 6000 pounds
20 × 75 pounds boxes = 1500 pounds
6000 pounds + 1500 pounds = 7500 pounds
The missing justification is for the statement that three angles add to a particular angle. The appropriate choice is ...
... c. Angle Addition Postulate
2/5=4/10=12/30 1/3=10/30 12/30+10/30=22/30 22/30=11/15
Mr. Mole's burrow was at an altitude of 6 meters below the ground.
Step-by-step explanation:
Step 1:
We need to determine the distance that Mr. Mole covers in a single minute.
To do that we divide the difference in values of altitude by the difference in the time periods.
For the first case, Mr. Mole had traveled -18 meters in 5 minutes.
We also have, he traveled -25.2 meters in 8 minutes.
Step 2:
The distance he covered in 1 minute 

So with every minute, Mr. Mole digs down an additional 2.4 meters below the surface.
To determine where Mr. Mole's burrow is we subtract the distance traveled in 5 minutes from -18.
The altitude of Mr. Mole's burrow 
So Mr. Mole's burrow was at an altitude of 6 meters below the ground i.e. -6 meters.
