Answer:
1440
Step-by-step explanation:
40% of 3600
40% = 0.4
of = ×
40% of 3600
0.4 × 3600 = 1440
Answer:
No solutions
Step-by-step explanation:
x+2y=2
2x+4y=-8
Multiply the first equation by 2:
2x+4y=4
Since 2x+4y are equal to both 4 and -8, this system must have no solutions. Hope this helps!
Basically, this problem wants you to solve the area of the trapezoid given those dimensions, then multiply this to the unit cost to determine the total cost. The formula for the area of trapezoid is written below:
A = (a+b)h/2, where a and b are the lengths of the two bases
A = (15+9)(10)/2 = 120 cm²
Total Cost = 120 cm² * $0.80/cm² = <em>$96</em>
The angular velocity by definition is given by:
w = rev / t
Where:
rev: revolutions
t: time
Substituting values we have:
w = (6 * (2 * pi)) / (12)
w = 3.141592654 rad / s
Answer:
the average angular velocity of the spinner, in radians per second, for the 12-second interval is:
w = 3.141592654 rad / s
