Answer:
- Total number of cars having no defection
- Total number of cars out of 560 will have defects =
Step-by-step explanation:
As
- A car factory checks 320 cars, and
Total number of cars = 560
The number of cars defected out of the cars that have
been checked = 
The equation of the scenario will be:
![\left[560\:\times \:308\right]\:\div \:320](https://tex.z-dn.net/?f=%5Cleft%5B560%5C%3A%5Ctimes%20%5C%3A308%5Cright%5D%5C%3A%5Cdiv%20%5C%3A320)
⇒ 
so
- Total number of cars having no defection
- Total number of cars out of 560 will have defects =
Answer:
7.5 hours
Step-by-step explanation:
We can model an equation for this problem.
We can write:
Where
F is the final temperature (15 degrees we need)
m is the rate of temperature change (2 degrees per hour)
and
t is the time, in hours, it will take (we need to find this)
It is given,
F = 15
m = 2
So, t would be:
F = mt
15 = 2t
t = 15/2 = 7.5
So it will take 7.5 hours
42 received an A
so 40-42 = 38 did not
the fraction would be 38/80, divide both numbers by 2
38/80 reduces to 19/40 did not receive an A
Answer:
6x^2+ 19x+8
Step-by-step explanation:
(3x+8)(2x+1) use foil method which gives you,
6x^2+16x+3x+8 then combine like terms which gives you,
6x^2+ 19x+8.
