Answer:
0.1 mole per liter
Step-by-step explanation:
i got it right
FInd the circumference of the tire:
C = 2 x PI x r
C = 2 x 3.14 x 14
C = 87.92 inches.
For every revolution of the tire it travels 87.92 inches.
In one minutes the car travels 87.92 x 120 = 10,550.4 inches.
In 5 minutes the car travels 10550.4 x 5 = 52,752 inches.
52,752 / 12 = 4,396 feet
1 mile = 5280 feet
4396 / 5280 = 0.833 miles
I calculated 3 different measurements. Use the one needed.
Answer:
8.3 * 10 ^5
Step-by-step explanation:
830000
To change this to scientific notation, we move the decimal 5 places to the left. The exponent will be positive 5 because we moved it to the left
8.3 * 10^ +5
8.3 * 10 ^5
Answer:
b = 161, m = 111
Step-by-step explanation:
b + m = 272
m + 50 = b
Substitute
m + 50 + m = 272
2m = 222
m = 111
Plug in for m
b + 111 = 272
b = 161
