Answers
60+12(5)=60
if he buys the player plus 4 movies at movies-n-more the total would also be $120

the massive rear tire of a tractor rotates and moves the tractor 100 yards across a field in 4 minutes. Determine the linear velocity of the outer edge of the massive tire. Is the linear velocity of the outer edge of the smaller tire faster or slower than the massive tire? Which has a greater angular velocity?
Answers
9514 1404 393
Answer:
a) 25 yards per minute
b) linear velocity is the same
c) smaller tire has greater angular velocity
Step-by-step explanation:
a) The linear velocity of the edge of the tire is the same as the linear velocity of the tractor: (100 yd)/(4 min) = 25 yd/min
__
b) All parts of the tractor have the same linear velocity. The outer edge of the smaller tire is moving at the same linear velocity.
__
c) Because the smaller tire must make more turns to cover the same distance in the same time, its angular velocity (turns/time) is greater.
The smaller tire has greater angular velocity.
3x+4=9x-8= ????????????
Answers
Simplifying
3x + 4 = 9x + -8
Reorder the terms:
4 + 3x = 9x + -8
Reorder the terms:
4 + 3x = -8 + 9x
Solving
4 + 3x = -8 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
4 + 3x + -9x = -8 + 9x + -9x
Combine like terms: 3x + -9x = -6x
4 + -6x = -8 + 9x + -9x
Combine like terms: 9x + -9x = 0
4 + -6x = -8 + 0
4 + -6x = -8
Add '-4' to each side of the equation.
4 + -4 + -6x = -8 + -4
Combine like terms: 4 + -4 = 0
0 + -6x = -8 + -4
-6x = -8 + -4
Combine like terms: -8 + -4 = -12
-6x = -12
Divide each side by '-6'.
x = 2
Simplifying
x = 2

Find the length of the missing side. Simplify all radicals.
Answers
Answer:
b = 9√5 (see below)
Step-by-step explanation:
Using the Pythagorean Theorem, you can find the missing side. The two sides connect to the right angle are the legs, and the sloping side across from the right angle is the hypotenuse.
We know that:
a² + b² = c²
—where a and b are legs and c is the hypotenuse.
Plug in the known values:
a² + b² = c²
18² + b² = 27²
324 + b² = 729
b² = 405
√b² = √405
b = √81 √5
b = 9√5
Answer:
20
Step-by-step explanation:
A^2+B^2=C^2
18^2+B^2= 27^2
324+B^2= 729
-324 -324
B^2 = 405
B= [tex]\sqrt{405)\\[/tex]
