Answer:
3780 bolts will be made by 8pm
Step-by-step explanation:
One Hour : 500 nuts or 840 bolts
Divide by 2
30 minutes : 250 nuts or 420 bolts
750 nuts : 500 + 250 = 750
so the machine took 1 hour and 30minutes
14:00 it started (2pm)
15:30 it switched to bolts
20:00 (8pm)
4 hours and 30minutes to get to 8pm
<u>840 × 4 = 3360 bolts + 420 bolts = 3780 bolts was made</u>
Answer:
y = √7
Step-by-step explanation:
This circle has a center at (0,0) and a radius of 4 so its equation is:-
x^2 + y^2 = 16
when x= -3, (-3)^2 + y^2 = 16
9 + y^2 = 16
y^2 = 7
y = √7
Isolate x to one side on the equation the solve
