So it will be
1/3(6)=-2/5(-5)
then will remove minus
1/3*6=2/5*5
then cancle 3 and 6 will be 2 and remove 5
So it become like this 2=2 it is True
Answer:
"None of the answers are correct."
Step-by-step explanation:
The formula for Area given the circumference is A = ![\frac{C^{2} }{4\pi }](https://tex.z-dn.net/?f=%5Cfrac%7BC%5E%7B2%7D%20%7D%7B4%5Cpi%20%7D)
![\frac{26^{2} }{4\pi } = 53.79437](https://tex.z-dn.net/?f=%5Cfrac%7B26%5E%7B2%7D%20%7D%7B4%5Cpi%20%7D%20%3D%2053.79437)
So none of the above are correct
I believe its c, sorry if im wrong.
Answer:
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Step-by-step explanation:
Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.
car = ( x + 19 ) mph
truck = ( x ) mph
Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:
(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )
Substitute,
( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048
Simplify,
8x + 152 + 8x = 1048
16x + 152 = 1048
-152 -152
16x = 896
/16 /16
x = 56
Add (19) to find the speed of the car:
truck speed + 19
= 56 + 19
= 75
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Answer:
2A/h - a = b
Step-by-step explanation:
Using A= 1/2(a+b)h
Divide both side by h
⇒A/h = 1/2(a + b)
Mutiply both sides by 2
⇒2A/h = a + b
Take the 2 over to the other side
2A/h - a = b
Keep in mind, that the (a) is not on the bottom, rather on its own
