given :-
p(t) = 3t^2 - 5t - 7
g(t) = t - 5
=> t = 5
on putting values..
p(5) = 3(5)² + 5(5) - 7
= 3(25) + 25 - 7
= 75 - 18
= 57
hence, the remainder is 57.
D. 57 is the correct option
Answer:
2 hrs, 24 min
Step-by-step explanation:
Sally: in one hour, she can paint 1/4 of the room.
Joe: in one our, he can paint 1/6 of the room
Hour one: 1/4+1/6=3/12+2/12=5/12
1÷5/12=1*12/5=12/5
12/5= 2 & 2/5 hours, or 2.4 hours, or 2 hrs 24 minutes

Answer
5.5cm
Step-by-step explanation:
The radius of a circle is the distance from the center of the circle to any point on its circumference.
The easiest way to find the radius is by dividing the diameter in half.
Radius = 1/2 × diameter
Here diameter is given as 11 cm.
Hence Radius = 1/2 × 11 cm.
= 11/2 cm.
= 5.5 cm.
Answer:
Step-by-step explanation:
Number of phones broken = 3
Number of phones not broken = 15
Total number of phone in the shipment = 18
Since a not broken phone has been randomly selected, the number of phones not broken reduces to 14. And the total number of phones would be 17.
Pr(of newly selected phone NOT broken) = 
=
Therefore, the probability of the selected phone not being broken is .
