Answer:
2 miles per hours
Step-by-step explanation:
You divide 1/3 mile by 1/6 hour
Use the reciprocal.
1/3 x 6/1 = 2/1
Simplify
2/1 = 2
You can also solve it this way:
If 1/6 hour is 10 minutes, and it takes 10 minutes to walk 1/3 a mile, then it would take 30 minutes to walk a mile.
30 x 2 = 60
Either way, Richard walks 2 miles per hour.
Answer:
Minimum - 8.1 inches
Maximum - 8.35 inches
Step-by-step explanation:
The specifications for manufacturing a steel rod stipulate that the length must be 8.225 ± 0.125 inches.
This means that the minimum length must not be 0.125 inches less than 8.225 inches and the maximum length must not be 0.125 inches greater than 8.225 inches.
The minimum length is therefore:
8.225 - 0.125 = 8.1 inches
The maximum length is therefore:
8.225 + 0.125 = 8.35 inches
Mosquito = 2.5 x 10⁻⁶
Housefly = 2 x 10⁻⁵
Let's find their ratio: Mosquito/Housefly = (2.5x10⁻⁶)/(2 x 10⁻⁵)
M/H =(2.5/2) x (10⁻⁶/10⁻⁵)
M/H = (5/4) x (10⁽⁻⁶⁺⁵⁾
M/H = (5/4) x 10⁻¹
M/H = (5/4) x (1/10)
M/H = 5/40
M/H = 1/8 OR 8 M = 1 H , SO the housefly is 8 times the weight of the mosquito
Answer:
x^2 - 6x + 2
Step-by-step explanation:
(x^2 - x + 4) - (5x + 2)
x^2 - x + 4 - 5x - 2
x^2 - 6x +2
