Answer:
You need to divide 64 by 12/45. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 64 times 45/12. Which is 240/1 which is 240.
Step-by-step explanation:
Using simple algebra, it is found that Amanda will be able to cut 20 pieces of [tex]12\frac{4}{5}[/tex] inches length.
What is algebra?Algebra is the branch of mathematics that deals with mathematical operations and symbols operating on numbers, variables and expressions
Let Amanda cut total x pieces
Given that length of each piece =[tex]12\frac{4}{5}[/tex] inches = 64/5 inches
Total length cut for all the pieces can be found by multiplying the number of pieces with length of each piece
∴ Total length cut for x pieces = x × 64/5 = 64/5 x
Given that Amanda has 4 boards for cutting
Length of each board = 64 inches
Total length offered by 4 fours boards for cutting is calculated by multiplying length of each board by 4 .
Total length offered for cutting by 4 boards = 4 × 64 = 256 inches
Therefore,
Total length cut for x pieces = Total length offered for cutting by 4 boards
⇒ 64/5 x = 256
⇒ x = 256/(64/5) = (256×5)/64 = 4×5 = 20
Therefore, There will be 20 pieces cut from all four boards .

Answer:
2^3
Step-by-step explanation:
Ok, let's jump right in!
Multiply 2^6 by 2^−3 by adding the exponents.
Use the power rule a^m a^n = a^m+n to combine exponents. Therefore, we get:
2^ 6-3
Subtract 3 from 6.
2^3
TIP: For next time remember that when you have to multiply exponents you that have the same base number you really just have to add the exponents.

If p(x)=(3x+2)(2x−3), what are the zeros of the polynomial?
x=-23 and x=32
x=23 and x=-32
x=-2 and x=3
x=2 and x=-3
Answer:
Option A is the correct answer. ; x=-2/3 and x=3/2
Step-by-step explanation:
We have been given that p(x)=(3x+2)(2x−3) is a polynomial.
According to the question's statement, Question asks us to find the zeros of the polynomial.
Let's head to the question in order to get required answer.
p(x)=(3x+2)(2x−3)
=> p(x) = 3x(2x-3) + 2(2x-3)
=> p(x) = 6x² - 9x + 4x - 6
=> p(x) = 6x² - 5x - 6 (This is the standard form for the given polynomial)
Now, We need to find the zeros of the polynomial. So, In order to find its zeros, we need to put p(x).
p(x) = (3x+2)(2x-3)
=> 0 = (3x+2)(2x-3)
=> (3x+2) = 0 or (2x-3) = 0
=> x= -2/3 or x = 3/2
Hence, If p(x)=(3x+2)(2x−3), x = -2/3 & x= 3/2 are the zeros of the polynomial.
The perimeter of a rectangle is 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation Find the length, in centimeters, if the width is 3.6 centimeters
Step-by-step explanation:
let the unknown be x
length = x
width = 3.6 cm
Perimeter = 2 lengths + 2 widths
48 cm = x + x + 3.6 + 3.6
48 cm = 2x + 7.2
40.8 = 2x
20.4 cm = x
if you wanna check,
perimeter = 20.4 + 20.4 + 3.6 + 3.6
48 cm = 48
Using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.
Recall:
Perimeter of a rectangle (P) = 2(L + W) (relationship between the width, length and perimeter)
Given:
Width (W) = 3.6 cmPerimeter (P) = 48 cmLength (L) = ?Using the relationship between the dimension of a rectangle and its perimeter, the following equation would be derived:
48 = 2(L + 3.6)
Solve for the value of L48 = 2L + 7.2
Subtract 7.2 from each side48 - 7.2 = 2L
40.8 = 2L
Divide both sides by 220.4 = L
L = 20.4 cm
Therefore, using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.

f(x)= 1/x, vertically stretched by a factor of 7, reflected in the y-axis, translated 5 units to the right, and translated 3 units downward.
Answer:
-7/(x-5) - 3
Step-by-step explanation:
First off, to reflect an equation in the y axis, just multiply by -1. Now that it is reflected, to stretch an equation by a factor of 7, multiply it by 7. Now we have -7/x.
Then, to move an equation down by 3 units, simply subtract it by 3. Now we have -7/x - 3.
Lastly, since you want to translate it 5 units to the left, you want the equation to be undefined at x = 5 (because originally it is undefined at x = 0). To do that, set the denominator to x - 5. We arrive at our answer: -7/(x-5) - 3.
Using translation concepts, it is found that the new definition for the function is:
[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]
----------------------------
The parent function is:
[tex]f(x) = \frac{1}{x}[/tex]
A vertical stretch by a factor of a means that the function is multiplied by a.Factor of 7, thus:[tex]g(x) = 7 \times \frac{1}{x} = \frac{7}{x}[/tex]
Reflection over the y-axis means that we have g(-x), thus:[tex]g(-x) = \frac{7}{-x} = -\frac{7}{x}[/tex]
Translating a units to the right is g(x - a), 5 units, thus:[tex]g(x) = -\frac{7}{x - 5}[/tex]
a units downward means that a is subtracted from the function, 3 units, thus:[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

The length of cell A is 8x10 to the power of negavtive 6 m. The length of cell B is0.0000004 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.
Answer:
Ratio of length of cell A to cell B is 20 : 1
Step-by-step explanation:
Length of cell A = [tex]8\times 10^{-6}[/tex] m
Length of cell B = 0.0000004 m
Convert the length of cell B into scientific notation.
Length of cell B = [tex]4.0\times 10^{-7}[/tex]
Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]
= [tex]2\times 10^{7-6}[/tex]
= 20
Therefore, ratio of length of cell A to cell B is 20 : 1

Work out the size of angle x
Answer:
Let's name the angle right close to 51 as c.
c = 180°-51° since angles on a straight line is equal to 180°.
so c= 129°
so x = 129° since it corresponds to c
Answer:
Step-by-step explanation:
Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:
180-51=129
The final answer to this problem is 129 degrees.
