Answer:
152.7 cm/s
Step-by-step explanation:
The radius of DVD, r = 6 cm
The angular speed of DVD, [tex]\omega=243\ rev/min=25.45\ rad/s[/tex]
We need to find the linear speed of the DVD.
The relation between linear speed and angular speed is given by :
[tex]v=r\omega\\\\v=0.06\times 25.45\\\\v=1.527\ m/s[/tex]
or
v = 152.7 cm/s
So, the linear speed of the DVD is 152.7 cm/s.

1.) The length of a rectangle is 4 cm longer than the width. The
perimeter is 80 cm. Find the length and width. Write a system and
use substitution to solve.
Step-by-step explanation:
if a rectangle has 4 sides and there are two lengths and two widths
then we could split 80 by 2 and minus 4 from the length and then split that into two.
then your answer would be and 36 and 44
and the total answer would be half of each so the L=22 and L=22
and the W=18 and W= 18

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 700 kW in a 12 m/s wind, how much power does it generate in a 6 m/s wind?
(The formula for P as a power function of v is P = a ⋅ v3.
A. 88 kW
B. 175 kW
C. 125 kW
D. 1050 kW
Answer:
New power = 88 Kw (Approx.)
Step-by-step explanation:
Given:
P = a(v³)
Old power p = 700 Kw
Old wind speed v = 12 m/s
Find:
New power when v = 6m/s
Computation:
P = a(v³)
700 = a(12³)
a = 0.4050 m²
New power = a(v³)
New power = (0.4050)(6³)
New power = 87.48
New power = 88 Kw (Approx.)

How would you express the area of the rectangle using the Distributive Property?
Answer:
C
Step-by-step explanation:
Step 1: Find your legth and width
Length = x + 5
Width = 3
Step 2: Use area formula to find area
l x w = A
(x + 5) x 3 = A
A = 3(x+5)
Step 3: Therefore Statement
Thereforethe answer to the question is C. 3(x+5)
Answer:
C. 3(x + 5)
Step-by-step explanation:
area of rectangle = length * width = width * length
A = area of largest rectangle
a1 = area of left rectangle
a2 = area of right triangle
The largest rectangle is made up of the the two smaller rectangles.
A = a1 + a2
Left rectangle: a1 = WL = 3x
Right rectangle: a2 = WL = 3 * 5
Total area of the two small rectangles:
A = a1 + a2 = 3x + 3 * 5
Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:
A = 3x + 3 * 5 = 3(x + 5)
The area of the largest rectangle is 3(x + 5)
We can also find an expression for the area of the largest rectangle directly by looking at its length and width.
The length of the largest rectangle is x + 5.
The width of the largest rectangle is 3.
A = WL
Substitute 3 for W, the width.
Substitute x + 5 for L, the length.
A = 3(x + 5)
Answer: C. 3(x + 5)

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A spinner with six section numbered from 1 to 6.
total number of times spins = 150
So, the number of times the number comes less than 5 is
= 150 x 1/5
= 150/5
= 30
