Answer:C
Step-by-step explanation:
Answer:
<em>120 minutes or 2 hours</em>
Step-by-step explanation:
<u>Proportions</u>
The method to solve the problem is to compute how many cans produce each machine per minute, then add them to obtain the total cans produced by both. Finally, we compute the time to produce 4200 cans at that level of production.
The newer machine produces 4200 cans in 210 minutes, it means it produces
=20 cans per minute
The older machine needs 280 minutes to produce the same 4200 cans, to it produces
= 15 cans per minute
Together, they produce 20+15=35 cans per minute. Thus, to produce 4200 cans, they need
= 120 minutes or 2 hours
There ya go! Hope this helped
Answer:
79 degrees
Step-by-step explanation:
A. Sum of interior angles is where you take two of the interior angles (ones inside the triangle) and add them to get the opposite angle outside the triangle, D in this case. So 41 + 38 = 79 degrees
B. a straight line has 180 degrees, you are given the angle next to D to be 101, so you find the difference between 180 and 101 to find D, so 180-101 = 79 degrees
25x/45=-65
25x=2925
x=117
