$22.50 per hour. If Britt spends a total of
$940 over the summer, how many hours did
she train with the trainer?
Answer:
the minimum speed, in feet per second, that the conveyor must move is 7.07143 ft/sec
Step-by-step explanation:
Let's assume time it takes to cool is 't' seconds
so, we are given
The castings cool at the rate of 0.3°F (degrees Fahrenheit) per second
so, total change in temperature will be
must not be allowed to cool more than 7°F before being heat treated
so, that temperature must be equal to 7
now, we can solve for t
sec
now, we are given length of casting is 55 yards
so, firstly we will change it into ft
1 yard =3 ft
so,
so, we have
total length =55 ft
now, we can use speed formula
we can plug values
so, speed is 7.07143 ft/sec
Answer:
7.07 is the answer i got as well
Step-by-step explanation:
three angles measuring 75°, 45°, and 60°
three sides measuring 7 m, 10 m, and lym
three angles measuring 40°, 50%, and 60°
three sides measuring 3 cm, 4 cm, and 5 cm
Answer:
Step-by-step explanation:
three angles measuring 75°, 45°, and 60°
75+45+60 = 180 -> can create triangle
three sides measuring 7 m, 10 m, and lym (assume this is 16)
satisfy this a-b<c<a+b -> can create triangle
three angles measuring 40°, 50%, and 60°
40+50+60 = 150 ≠ 180 -> cannot create triangle
three sides measuring 3 cm, 4 cm, and 5 cm
satisfy this a-b<c<a+b -> can create triangle
Answer:
20+30h
