What is PEDMAS rule?PEDMAS is an acronym for the words parenthesis, exponents, division, multiplication, addition, subtraction. The PEDMAS Rule is a set of rules that prioritize the order of calculations.
Given
([tex]4^{-1}[/tex])([tex]2^{3}[/tex] ÷ [tex]4^{-2}[/tex])
= [tex](4^{-1})[/tex] [tex](\frac{2^{3} }{4^{-2} })[/tex]
= [tex](4^{-1})[/tex][tex](\frac{2^{3} }{4^{-1}. 4^{-1}})[/tex]
= [tex](\frac{2^{3} }{4^{-1} })[/tex]
= [tex]2^{3} . 4^{1}[/tex]
= 8 × 4
= 32
Hence, number is the same as ([tex]4^{-1}[/tex])([tex]2^{3}[/tex] ÷ [tex]4^{-2}[/tex]) is 32.
Option D is correct.

Daniel receives a 35% employee discount on all purchases he makes at the store. If he buys his brother a jersey that is regularly priced at $24.95, what price (before tax) will Daniel pay for the jersey?
ANSWER CORRECTLY AND I WILL GIVE YOU BRAINLIEST AND GET 10 POINTS
Answer:
The price to pay is $16.22
Step-by-step explanation:
From the question, the regular price is $24.95
now, there is a discount
So the price to pay is the regular minus the discount
Mathematically, we have this as:
24.95 - 35% of 24.95
= 24.95 - 0.35(24.95)
= $16.2175
This is approximately $16.22
What is the range of possible sizes for side x in triangle side lengths of 8.0 and 4.0?
Answer:
4<x<12
Step-by-step explanation:
8.0+4.0=12.0
8.0-4.0=4.0 or 4
The rules of triangles is that it must be less than the sum you had when you first added 8.0and 4.0 which was 12
So therefore , 4< x < 12

Write the equation x2 + 24x + 60 = 0 in the form (x + p)2 = q.
A. (x + 12)2 = –60
B. (x + 12)2 = 84
C. (x + 12)2 = 204
D. (x + 6)2 = –24
The Answer is
A.(x+12)2 = -60
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The formula for (a + b)² = a² + 2ab + b²
The equation x² + 24x + 60 = 0 in the form (x + p)² = q is
(x + 12)² = 84
Option A is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
x² + 24x + 60 = 0
We can write this as,
x² + 2 x 12 x (x) + 60 = 0
The formula for (a + b)² = a² + 2ab + b²
Add 144 on both sides.
x² + 2 x 12 x (x) + 60 + 144 = 0 + 144
x² + 2 x 12 x (x) + 144 + 60 = 144
[ 12² = 144 ]
Subtract 60 on both sides.
x² + 2 x 12 x (x) + 144 = 144 - 60
x² + 2 x 12 x (x) + 12² = 84
(x + 12)² = 84
Thus,
The equation x² + 24x + 60 = 0 in the form (x + p)² = q is
(x + 12)² = 84
Option A is the correct answer.

Answer:
Step-by-step explanation:
Length : Breadth : height = 3 : 4 : 6
Length = 3x
Breadth = 4x
Height = 6x
Volume of cuboid = 576 sq.cm
length * breadth * height = 576
3x * 4x * 6x = 576
72x³ = 576
x³ = 576/72
x³ = 8
x³ = 2³
x = 2
Length = 3*2 = 6 cm
Breadth = 4* 2 = 8 cm
Height = 6*2 = 12 cm
Total surface area = 2*(lb + bh + hl)
= 2 * (6*8 + 8*12 + 12*6)
= 2 * (48 + 96 + 72)
= 2 * 216

Answer: 2n - 64
Step-by-step explanation:
If the vairiable n describes the unknown number, and there is twice the number, then we can use the term 2n.
We also have 64 less then that number, and less means to subtract. Therefore, the equation is 2n - 64.
Answer:
2n-64
Step-by-step explanation:
I believe this is the correct answer (Not exactly sure to be honest)
Twice a number means to multiply by 2, so you use the variable (n) and multiply it by 2. For subtracting 64, I believe you usually put it after the (2n) portion of the equation. You may have to flip it though, equation order is important and it's been a while since I've done these so apologies if it's wrong! Good Luck!
Suppose () = 46%; ( and ) = 10%; and ( or ) = 62% Find (Not ). Can this really be a probability? If not, explain why not.

[tex]P(E\ or\ F) = 62\%[/tex]

Find P(E)
In probability:
[tex]P(E\ and\ F) = P(E) + P(F) - p(E\ or\ F)[/tex]
Substitute the right values
[tex]10\% = P(E) + 46\% - 62\%[/tex]
[tex]10\% = P(E) -16 \%[/tex]

BD=24
Step-by-step explanation:
I assigned my unkown sides of the triangles as x and y, where x = BD and y =AD.
I used pythagoras' theorem to find expressions for the the sides of the triangles in terms of x and y.
Both expressions had the term x^2 in them, so I equated expressions of x^2
From there i rearranged to find y.
Using my value of y, I found x.
