Answer:
[tex]\frac{1}{64}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]
and 4³ = 4 × 4 × 4 = 16 × 4 = 64
Then
[tex]4^{-3}[/tex] = [tex]\frac{1}{4^{3} }[/tex] = [tex]\frac{1}{64}[/tex]

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length. The length of a rectangle is 23 feet more than the width. If the perimeter is 70 feet, then what is the length of the rectangle, in feet?
Answer:
Length = 6 + 23 = 29 feet
Step-by-step explanation:
Width = x
Length = x + 23
2x + 2(x+23) = 70
2x + 2x + 46 = 70
4x = 70-46
x = 24/4
x = 6

Group of answer choices
{11, 18, 25, 32, 39}
{28, 35, 42, 49, 56}
{4, 5, 6, 7, 8}
{28, 42, 56, 70, 84}
Your answer is D){28, 42, 56, 70, 84}
To answer this question you just have to make sure the amount he pays is a multiple of 7.If you know you times table then this should be easy
Times table of 7:
7,14,21,28,35,42,49,55,63,70,77,84.
Now you just need to find an answer choice who has these numbers.Lets check it out!
A) 11 isn't a multiple of 7
B) 56 isn't a multiple of 7
C) None of these are multiples of 7 except 7 so this is also incorrect
D) This is correct because they are all multiples of 7
Hope this makes sense.

Which lines are perpendicular to the line y –1=1/3(x+2)?
check all that apply
y + 2 = –3(x – 4)

Answer:
1/3
Step-by-step explanation:
1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!
[tex]3 * \frac{1}{3} = \frac{3}{3} = 1[/tex] [tex]6 * \frac{1}{3} = \frac{6}{3} = 2[/tex] [tex]12 * \frac{1}{3}= \frac{12}{3}=4[/tex] [tex]15*\frac{1}{3}=\frac{15}{3} =5[/tex]2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.

Answer:
[tex]3781/9000[/tex]
Step-by-step explanation:
[tex]0.42\overline{1}=42/100+0.00\overline{1}[/tex].
Recall that [tex]0.\overline{1}=1/9[/tex].
So, we want [tex]42/100+1/9*1/1000[/tex].
This simplifies to [tex]21/50+1/9000[/tex].
We know that [tex]21/50=(21*180)/(50*180)=3780/9000[/tex].
So, our expression is [tex]3780/9000+1/9000=3781/9000[/tex], which can't be simplified more.
So, our answer is [tex]\boxed{3781/9000}[/tex] and we're done!

Answer:
-7 3/4 (or it can be written as -31/4, an improper fraction)
Step-by-step explanation:
[tex]\left(\frac{1}{2}\right)^2-6\left(2-\frac{2}{3}\right)[/tex] [tex]\frac{1}{4} - 6(2-\frac{2}{3})[/tex] [tex]\frac{1}{4}-6(1\frac{1}{3})[/tex] [tex]\frac{1}{4} - 6 * \frac{4}{3}[/tex] [tex]\frac{1}{4} - \frac{24}{3}[/tex] [tex]\frac{1}{4} - 8[/tex] [tex]\frac{-31}{4}[/tex] [tex]-7\frac{3}{4}[/tex]Therefore, the answer is -7 3/4 as a mixed number and -31/4 as an improper fraction (they're the same thing).

Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 before tax was added. What was the cost of each sweat?
Answer:
$35
Step-by-step explanation:
first we need to find the amount of money the sweaters cost alone.
so we first subtract the total (160) - the skirt price (20) which is 140
now we divide it by 4 to find the price of each seater, as they all cost the same.
so 140 divided by 4 = 35
answer: $35

Find the value of x
solving steps
Answer:
x = 8
Step-by-step explanation:
Supplementary angles add up to 180 degrees to make a straight line.
The red square in one of them indicates that it is 90 degrees on their side which means that it is 90 degrees on the other where (6x+2) and 40 degrees are.
(6x+2) + 40 = 90
6x + 42 = 90
6x = 48
x = 8
Express as a trinomial.
(2x – 4)(x + 8)
Answer:
[tex](2x - 4)(x + 8) \\ 2x - 4(x + 8) \\ 2x - 4x + 32 \\ 2x + 32[/tex]
