Ian says that if x < y, then | x | < | y |. Give one example where Ian's statement is true. Then provide one example that proves Ian's statement is not always true. hurry please! ill give brainliest
Solution:
Proving that Ian is not always true:
|x| < |y| (x and y must be positive)=> |-5| < |-4|=> 5 < 4 (False)Proving that Ian is sometimes true:
|x| < |y| (x and y must be positive)|4| < |5| 4 < 5 (True)This proves that:
If x and y are positive, Ian's statement will be true. If x and y are negative, Ian's statement will be false.Kylie works at a local music store. The store receives a shipment of new CDs in a box. In the shipment, there are 10 country CDs, 5 rock CDs, 12 hip hop CDs, and 3 jazz CDs.
What is the probability that the first CD that Kylie pulls from the box will NOT be hip hop?
Answer:
Total number of CDs= 10+5+12+3=30
Number of jazz CD= 3
Total number of outcomes that Kyle will select a jazz CD from the box= 3C1= 3!/1!2!= 3
Total number of outcomes for any CD = 30C1 = 30!/1$29! =30
Hence, the probability of picking jazz CD =3/30 = 1/10 0.1
Now since, one CD is out, the total number of CD left = 29
No. of country CD= 10
Total number of outcomes that Kyle will select a country CD from the box= 10C1= 10!/1!9!= 10
Total number of outcomes for any CD(one is out) = 29C1 = 29!/1$28! =29
Hence, the probability of picking country CD =10/29 = 0.344827

Answer:
[tex]\frac{4}{33}[/tex] and [tex]\frac{1}{27}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating numbers placed after the decimal point.
let x = 0.1212...... (1) ← multiply both sides by 10
100x = 12.1212.... (2)
subtract (1) from (2) thus eliminating the repeating numbers
99x = 12 ( divide both sides by 99 )
x = [tex]\frac{12}{99}[/tex] = [tex]\frac{4}{33}[/tex] ← in simplest form
-------------------------------------------------------
let x = 0.037037....... (1) ← multiply both sides by 1000
1000x = 37.037037..... (2)
subtract (1) from (2) to eliminate the repeating numbers
999x = 37 ( divide both sides by 999 )
x = [tex]\frac{37}{999}[/tex] = [tex]\frac{1}{27}[/tex] ← in simplest form

If the exterior angle of a regular polygon is 7.2 degrees, what is the name of that polygon?
Answer choices:
25-gon
Heptagon
50-gon
Hexagon
A regular polygon with exterior angle of 7.2 degrees is a 50-gon.
Regular polygonRegular polygon are polygon that are equiangular. This simply means they are polygon with equal angles.
The formula to find the number of sides of a polygon using exterior angle is as follows:
exterior angle = 360 / nwhere
n = number of sides
Therefore,
7.2 = 360 / n
cross multiply
7.2n = 360
divide both sides by 7.2
n = 360 / 7.2
n = 50
The polygon has 50 sides. Therefore, it is a 50-gon

What is the area of the shaded portion of the circle? (16π – 32) in2 (16π – 8) in2 (64π – 32) in2 (64π – 8) in2.
The area of the shaded portion is (16π - 32) in².
What is the area of the circle?The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter.
In the picture attached, the circle is shown.
The area of one-quarter of the circle is given by;
[tex]\rm = \dfrac{1}{4}\times Area\ of \ a \ circle \\\\= \dfrac{1}{4}\times \pi \times radius^2\\\\ = \dfrac{1}{4}\times \pi \times 8^2\\\\= 16\pi \ in^2[/tex]
The area of the triangle is given by;
[tex]\rm = \dfrac{1}{2} \times base\times height \\\\= \dfrac{1}{2} \times 8\times 8 = 32 \ in^2[/tex]
The area of the shaded portion is;
Shaded area = Area of one-quarter of the circle - Area of the triangle = (16π - 32) in²

if the height of a rectangular prism is decreased by a scale factor of 1/2 how will the volume of the prism change????????
Answer:
Decrease by half.
Step-by-step explanation:
Let's say the length, width, and height is x,y,z respectively.
V = xyz
Now, when z is decreased by half, we get xyz : 2 which can either be written as (xyz) : 2 or xy(z:2)
So in short, if the height decrease by half, the volume will decrease in half.

Refer to the figure. Justify your answer. Each side length is doubled. Describe the change in the PERIMETER. *
Answer:
perimeter is doubled to 30.8 cm
Step-by-step explanation:
The perimeter is the sum of side lengths. The perimeter of this figure is the sum ...
4 cm + 5 cm + 6.4 cm = 15.4 cm
__
When the side lengths are doubled, the perimeter is doubled:
2(4 cm) +2(5 cm) +2(6.4 cm) = 2(4 cm +5 cm +6.4 cm) = 2(15.4 cm)
= 30.8 cm
The perimeter is doubled.

Two angles of a triangle measure 75° and 40°. What is the degree measure of the third angle?
Answer:
the angles of a triangle always equal 180 so
75+40+x=180
115+x=180
-115
x=65
the other angle is 65
Hope This Helps!!!
65°
Step-by-step explanation:
let the third angle be x
so, sum of all angles of a triangle = 180°
x° + 75° + 40° = 180°
x + 115° = 180°
x = 180° - 115°
