How many pieces of wire 2½ cm long, can be cut from a roll of wire 58 cm long?
No links please.
Answers
Step-by-step explanation:
Break it into steps you can better understand
2 1/2 = 2.50cm
You want to take as many 2.50 cm pieces as possible so you cut one off.
58 - 2.50 = 55.5
and another
55.5-2.50 = 53
and so on...
Instead of subtracting like this, we use division
58 / 2.5
when you divide, this tells you how many 2.50cm pieces you can cut from a total length of 58cm
Answer: 23
Step-by-step explanation: 2.5 x 23 = 57.5

Answers
Answer:
8(x-3)
2(4x-24)
Step-by-step explanation:
You are using the distributive property. Multiply the number outside of the parentheses by each number within the parentheses.
In 8(x-3) = 8x - (8×3) = 8x-24
In 2(4x-12) = (2 × 4x) - (2 × 12) = 8x-24

In the diagram, O is circumscribed about quadrilateral ABCD. What is m<B?
Answers
Answer:
B; 94 degrees
Step-by-step explanation:
From the diagram, what we have is a cyclic quadrilateral
For a cyclic quadrilateral, opposite angles are supplementary
That means;
They add up to give 180 degrees
Mathematically;
angle D + angle B = 180
angle B = 180 - angle D
angle B = 180-86
angle B = 94 degrees

[tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex]
↓
[tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex]
Step-by-step explanation:
Given - The matrices are -
[tex]\left[\begin{array}{ccc}2&6\\3&4\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}-2&-7\\5&9\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}2&4\\5&-5\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}3&2\\4&6\\\end{array}\right][/tex]
To find - Arrange the matrices in increasing order of their determinant values.
Proof -
Determinant of matrix [tex]\left[\begin{array}{ccc}2&6\\3&4\\\end{array}\right][/tex] is
= (2)(4) - (6)(3)
= 8 - 18
= -10
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}2&6\\3&4\\\end{array}\right][/tex] = -10
Determinant of matrix [tex]\left[\begin{array}{ccc}-2&-7\\5&9\\\end{array}\right][/tex] is
= (-2)(9) - (-7)(5)
= -18 + 35
= 17
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}-2&-7\\5&9\\\end{array}\right][/tex] = 17
Determinant of matrix [tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex] is
= (6)(-8) - (6)(5)
= -48 - 30
= -78
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex] = -78
Determinant of matrix [tex]\left[\begin{array}{ccc}2&4\\5&-5\\\end{array}\right][/tex] is
= (2)(-5) - (4)(5)
= -10 - 20
= -30
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}2&4\\5&-5\\\end{array}\right][/tex] = -30
Determinant of matrix [tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex] is
= (2)(4) - (5)(-2)
= 8 + 10
= 18
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}2&5\\-2&4\\\end{array}\right][/tex] = 18
Determinant of matrix [tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex] is
= (4)(2) - (-3)(5)
= 8 + 15
= 23
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}4&-3\\5&2\\\end{array}\right][/tex] = 23
Determinant of matrix [tex]\left[\begin{array}{ccc}3&2\\4&6\\\end{array}\right][/tex] is
= (3)(6) - (2)(4)
= 18 - 8
= 10
So,
Determinant of matrix [tex]\left[\begin{array}{ccc}3&2\\4&6\\\end{array}\right][/tex] = 10
Now,
Increasing order of Determinant is -
-78 < -30 < -10 < 10 < 17 < 18 < 23
So,
Order of the Matrix will be
[tex]\left[\begin{array}{ccc}6&6\\5&-8\\\end{array}\right][/tex]

Answers
Given:
On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22).
To find:
The range of x-values extrapolation occurs.
Solution:
Consider the below figure attached with this question.
From the graph or given points it is clear that the x-values are 0, 1, 3, 4, 6.
It means the x-values are from 0 to 6.
So, the range of the x-values is [tex]x\geq 0[/tex] or [tex]x\leq 6[/tex].
The required compound inequality for the range of x-values is [tex]0\leq x\leq 6[/tex].
Therefore, the correct option is D.

Answers
Given:
In a right triangle, the measure of one acute angle is 12 more than twice the measure of the other acute angle.
To find:
The measures of the 2 acute angles of the triangle.
Solution:
Let x be the measure of one acute angle. Then the measure of another acute is (2x+12).
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees. So,
[tex]x+(2x+12)+90=180[/tex]
[tex]3x+102=180[/tex]
[tex]3x=180-102[/tex]
[tex]3x=78[/tex]
Divide both sides by 3.
[tex]x=\dfrac{78}{3}[/tex]
[tex]x=26[/tex]
The measure of one acute angle is 26 degrees. So, the measure of another acute angle is:
[tex]2x+12=2(26)+12[/tex]
[tex]2x+12=52+12[/tex]
[tex]2x+12=64[/tex]
Therefore, the measures of two acute angles are 26° and 64° respectively.

N-2.5=5
Add -2.5 from itself, then do the same to the other side:
N-2.5=5
