4x+3x+1x=t, where x represents the number of people, and t represents the total cost.
So to solve it, it says Fitz and 3 friends so that’s four people, you’d substitute x for 4.
I hope this helps!
Equation would be 420 - 5m - 25w so the answer would be B. 4 months
If you would like to solve 60 is what percent of 72, you can calculate this using the following steps:
<span>60 is what percent of 72
</span>60 = x% of 72
60 = x% * 72
60 = x/100 * 72
60/72 = x/100
x = 60/72 * 100
x = 83.33%
The correct result would be 83.33%.
2pi radians=360 degrees
rato and proprtion
xrad/(2pi)=ydeg/360
xrad/2pi=82/360
times both sides by 2pi
xrad=164pi/360
xrad=41pi/90
aprox pi=3.141592
xrad=1.431
round
xrad=1.43 radians
1.43 radians=82 degrees
What you need to know for this case is that the linear velocity is defined as the product of the angular velocity by the radius.
We have then:
v = w * r
Substituting the values:
v = (45) * (15) = 675
v = 675 cm / min
answer:
The linear speed, in cm / min, of a point on the rim of the record is:
v = 675 cm / min
