Step-by-step explanation:

7r^2/21r^3

21r^3 ➡ 7r^3 × 3r^3

7r^2/7r^3×3r^3 ➡ 7r^2 - 7r^3/3r^3

➡7r^-1/3r^3

Billy goes on the teacup ride at the local carnival. He is seated 16 inches from the center of his teacup, which is spinning at
Orlov [11]

Answer:

Billy’s angular velocity, is 1508.16 radians per second

Step-by-step explanation:

We have to find angular velocity in radians per second

we have given angular velocity w = 4 revolutions per minute

we have to convert revolutions into radians and minutes into seconds.

so, we use the following conversion:

1 rev = 2* pi radians (where pi = 22/7 or 3.142)

1 min = 60 sec

putting the values in our equation : w = 4 revolutions per minute

=> w= 4 * ( 2* 3.142) *60

=> w= 1508.16 radians per second

hence Billy’s angular velocity, is 1508.16 radians per second

Answer:

c

Step-by-step explanation:

Step 1

Solve 3x-y=-63x−y=−6 for yy.

y=6+3xy=6+3x

Step 2

Substitute 6+3x6+3x for yy in the second and third equation.

2\left(6+3x\right)-5z=-52(6+3x)−5z=−5 x-\left(6+3x\right)-2z=-4x−(6+3x)−2z=−4

Step 3

Solve these equations for xx and zz respectively.

x=-\frac{17}{6}+\frac{5}{6}zx=−

x=-2x=−2

Step 8

Substitute -2−2 for xx in the equation y=6+3xy=6+3x.

y=6+3\left(-2\right)y=6+3(−2)

Step 9

Calculate yy from y=6+3\left(-2\right)y=6+3(−2).

y=0y=0

Step 10

The system is now solved.

x=-2x=−2 y=0y=0 z=1z=1

Solution

x=-2x=−2

y=0y=0

z=1z=1

marshall27 [118]
The answer is a) 1500 because when you divide 675 (the given number of students that cheated on 1 to 7 courses) by 1500 you get .45 or 45%.

Solve for w<br> s=w-10e<br> -------<br> m
polet [3.4K]
First, multiply both sides by m:
s*m = w - 10e
Then add 10e to both sides to isolate w:
s*m + 10e = w
or
w = s*m + 10e
