The correct answer is NO LINEAR FACTORS (option A ).
Answer:
157.1 m
Step-by-step explanation:
Here, we want to calculate the length of the semi-circle
This simply refers to the circumference of the semi-circle
Mathematically, the circumference is half that of a full circle
The circumference of a full circle is;
C = pi * d
For half circle or semi-circle;
It is ;
C = (pi * d)/2
D = 50 m
The circumference is thus;
C = 50 * 3.142
C = 157.1 m
Answer:
475 mph
Step-by-step explanation:
Distance = rate × time
time = distance / rate
If x is the speed of the plane in still air:
2100 / (x + 25) = 1890 / (x − 25)
Cross multiply:
2100 (x − 25) = 1890 (x + 25)
Distribute and solve:
2100x − 52500 = 1890x + 47250
210x = 99750
x = 475
-7/9 is repeating
42/50 is terminating
-1/125 is terminating
-77/600 is repeating
179/200 is terminating
5/11 is terminating
The way to figure this out is just by dividing the Numerator (top number) by the denomiter (bottom number)
Example 5÷11=.45454545 repeating
Answer:
n = 3
Step-by-step explanation:
9{n+2(n-2)} = 45
Start with the numbers on the inner most pair of parentheses
Multiply (n-2) by 2
9[n+2n-4] = 45
Add what is inside the parentheses
9[3n-4] = 45
Multiply
27n-36 = 45
Add 36 to both sides
27n = 81
Divide both sides by 27
n = 3
Hope this helps!
