Alright so lets look at 2.5 x 10^-2 shall we. Since the exponent of the scientific notation is negative -2 move the decimal point 2 places to the left. 0.025.
Lets do the second one shall we. this answer is the same as the first one so your answer should be
2.5 x 10^-2 = 2.5/10^2
Hope this helped :)
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.
You get it by cross multiplication
10×9÷3=30 and if you want to check
30 over 9 =3.333
10 over 3 = 3.333
What you have to do for this is to divide the total worth ($200,000.00) by the number of shares.
So this means that we need to count:
200 000 ÷4 000
here's a trick:
if you divide two numbers with many 0s at the end, you can always erase the SAME mount of 0s at the end (this is equivalent to dividing by 10).
so
200 000 ÷4 000
is equivalent to :
200 ÷4
which is 50! (4*50=200)
so the answer is that each share was worth 50 dollars.
