Length of arc = (15/360) * 2*3.14*20 = 5.23 ins
circumference of the circle = 2*3.14*24 = 150.72
angle at center from 10 ft arc = (10/150.72) * 360 = 23.89 degrees
Answer:
(n-14) / n
Step-by-step explanation:
n is your number;
"14 less" means "subtract 14", --> we have (n-14);
now we need to divide (n-14) by same number as your number, which is "n"---> final expression is: (n-14)/n
1 hour = 60 minutes
27/60 = 0.45 miles per minute
If A=w(50-w)
A=50w-w^2
dA/dw=50-2w
d2A/dw2=-2
Since the acceleration is a constant negative, that means that when velocity, dA/dw=0, it is at an absolute maximum for A(w)...
dA/d2=0 only when 50=2w, w=25
So as the case with any rectangle, the perfect square will enclose the greatest area possible with respect to a given amount of material to enclose that area...
So the greatest area occurs when W=L=25 in this case:
A(25)=50w-w^2
Area maximum is thus:
Amax=50(25)-(25)^2=625 u^2
Answer:
The height of the model is 138 cm.
Step-by-step explanation:
Simply multiply the height by the scale factor.
230*0.006
= 1.38 m
We need to convert this measure to centimeters. Centimeters are 1/100 of a meter. Therefore, we can multiply 1.38 meters by 100 to find how many centimeters it is equal to.
1.38*100 = 138
The height of the model is 138 cm.
