Answer:
Total number number of cars which do not have defects = 539
and 21 are defected out of 560 i.e. 560 - 539 = 21
Step-by-step explanation:
Total cars checked by Car factory = 320
Number of defected cars = 12
The number of cars which do not have defects = 320 - 12 = 308
Total Number of cars = 560
So the equation becomes
![\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)
⇒ 
⇒ 
⇒ 
Therefore, total number number of cars which do not have defects = 539
and 21 are defected out of 560 i.e. 560 - 539 = 21
Answer:
144/91
Step-by-step explanation:
24/7 ÷ 13/6
Keep the first fraction the same, change the sign, and flip the last fraction to solve

Answer:
8:24
Step-by-step explanation:
since 1:3 is already given to you
and 8:_ needs to be found
you know that the new ratio is 8 times bigger than the original one
multiply 1 by 8 and you get 8
multiply 3 by 8 and you get 24
P is 4 as 6 divide 36 is 6 so 6 divide 24 is 4 so
P=4
Answer:
It is a right triangle.
Step-by-step explanation:
By the Inverse Pythagoras Theorem if 39^2 = 36^2 + 15^2 then it is a right triangle.
39^2 = 1521
36^2 + 15^2 = 1296 + 225 = 1521.
So it is a right triangle.
