Answer: old machine 150, new machine 280
Step-by-step explanation:
given data:
Old machine = 25t
New machine = 35t
where t = hrs
we dont know the time for old machine so we assume it to be ( t ),
while that of the new machine is ( 14-t ) hours for new machine, and sum of 430 components.
therefore;
25t +490 - 35t = 430
-10t = -60
divide both sides by -10
t = 6 hours for the first machine.
6hrs * 25 components /hr
= 150 component parts For old machine.
for new machine
= 14 - t ........... eq1.
where ( t = 6 ), substitute t into the equation
= 14 - 6
= 8 hours for the second machine
= 8 * 35
= 280 components parts
Answer:
Step-by-step explanation:
Let's put in some numbers to make this easier to understand.
Let's say she has to travel 20 km.
On Monday, she travels at 4 kph. This takes 5 hours.
On Tuesday she travels 25% faster, at 5 kph. This takes 4 hours.
To figure percent reduction we take
100 % * (old - new) / old
100 % * (5 hr - 4 hr ) / 5 hr
100 % * 1 hr / 5 hr
100 % * 0.20
20% reduction.
Answer:
Step-by-step explanation:
<u>Angle formed by two chords is the half of the sum of the intercepted arcs:</u>
- 7x + 3 = 1/2(152 + 78)
- 7x + 3 = 115
- 7x = 112
- x = 112/7
- x = 16
Answer:
14 2/3 units^3

have a good day :)
Step-by-step explanation:
7 1/3 x 2=14 2/3
We get 65 miles away from Pittsburgh each hour, but we also started 80 miles away. Thus, our formula for dd is dd = 65tt + 80
