Answer:
-4+6*4 = 20
Step-by-step explanation:
If g is equal to 4 the answer is 20
Answer:
-7/3 & 5/2
Step-by-step explanation:
3x +7 = 0
3x = -7
x = -7/3
2x-5=0
2x = 5
X = 5/2
9.42 Units
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2(3.14)r
r = 2 therefore: 2(3.14)2 = 12.56
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us 9.42
Explanation:
I find it easiest to remember one or two facts and use those to figure others when needed. The primary fact I remember is
π radians = 180°
__
From this, you can determine ...
360° = 2π radians
90° = π/2 radians
60° = π/3 radians
45° = π/4 radians
30° = π/6 radians
The other angles on your chart are multiples of 30° or 45°, so will be corresponding multiples of π/6 or π/4 radians, respectively.
220 miles in 4 h = 55 mph multiply this by 5280 to get feet per hour then divide this by 60 to get ft/min
