In 3 minutes, a conveyor belt moves 200 pounds of recyclable aluminum from the delivery truck to a storage area. a smaller belt moves the same quantity of cans the same distance in 7 minutes. if both belts are used, find how long it takes to move the cans to the storage area. the conveyor belts can move the 200 pounds of recyclable aluminum from the delivery truck to a storage area in nothing minutes.

1.5 min

Step-by-step explanation:

rate of larger belt = 300/2 = 150

rate of smaller belt = 300/6 = 50

combined rate = 150+50=200  

time at combined rate = 300/200 = 1.5

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the first one

step-by-step explanation:

just id the test.
