Increased enrollment =9%
Last enrollment=3900
Current enrollment=9%of3900+3900
=9×3900/100+3900
=351+3900
=4451
F(4)=(4-1)+2*4=11...
This seems a bit too easy though, did you mean f(n)=f(n-1)+2n ? In this case :
f(1)=16
f(2)=16+2*2=20
f(3)=20+2*3=26
f(4)=26+2*4=34
Answer:
<u>Part 1:</u> Angle = 154.3°
<u>Part 2:</u> About 2.33 Rotations
Step-by-step explanation:
Part 1:
The arc length of a circle is given by the formula 
Where
- s is the arc length
- r is the radius of the circle
is the angle
**The angle are in radians and we will use radian**
When smaller gear has made 1 complete rotations (
radians), the arc length traveled is 
Now, what angle is swept by the larger circle when it travels 
? Put in 
and r is 7 to find :
** Since 
radians is 180°, we plug in 180 into and find the degree measure:
Angle = 154.3°
Part 2:
In one complete rotation of the larger gear, it travels a distance of:
We know that the smaller circle makes 1 rotation and travels 
, so in 
distance, it makes:
Rotations = 
About 2.33 Rotations
Answer:
6.37 cm.
Step-by-step explanation:
Since Hot Wheels uses a scale ratio of 1:64 (1 cm to scale = 64 cm actual) for their toys, knowing that the actual length of a VW Beetle is 160.6 inches, to determine the length of the toy car is you must perform the following calculation:
1 inch = 2.54 cm
(160.6 x 2.54) / 64 = X
407.924 / 64 = X
6.373 = X
Therefore, the size of the toy car will be 6.37 cm long.
Use keep, change, flip!
Ex: 1 / 3
— —
2 4
Keep the 1/2
Change the division sign to a multiplication sign
Flip the 3/4 to be 4/3
1 X 4
— —
2 3
Then, multiple and simplify as usual!
1 X 4= 4
2 X 3= 6
4 = 2
— —
6 3
The answer would be 2
—
3
Hope this helps, brainliest please! :)
