Answer:
208 1/8 hours
Step-by-step explanation:
The amount of time saved on each trip is ...
(3/4 h) - (1/4)(3/4 h) = (3/4)(3/4 h) = 9/16 h
There are 2×5×37 = 370 trips in the school year, so the total savings in time is about ...
370×(9/16 h) = 208 1/8 h
<span>a³-b³=(a-b)(a²+ab+b²)
64x⁶ - 27
64 = 4³,
x⁶ = (x²)³
27 = 3³
</span>64x⁶ - 27 = 4³(x²)³ -3³ = (4x²)³ -3³. Now, we can use a formula where a=4x², b=3
(4x²)³ -3³ = (4x² -3)((4x²)² +4x²*3 + 3²) = (4x² -3)(16x⁴ +12x² + 9)
<span>
Answer: </span>64x⁶ - 27= (4x² -3)(16x⁴ +12x² + 9) <span>

Answer:0.25 or 25%
Step-by-step explanation:
The correct answer is 12/20.
If you multiply the numerator and the denominator of 3/5 by 4/4:
3•4 = 12
————-
5•4 = 20
Therefore, the equivalent of 3/5 is 12/20.

Answer:
100 in is the answer.
Step-by-step explanation:
a = 60 in
b = 80 in
c = ?
According to the Pythagorean theorem,
a² + b² = c²
60² + 80² = c²
3600 + 6400 = c²
c² = 10000
c = 100 in
∴ the distance between the opposite corners of the bed is 100 in
