Amanda has four boards that are each 64 inches long. She needs to cut each board into multiple pieces that are each 12 45 inches long. How many pieces will she have after she cuts all four boards?
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 .

x3-8= 0
Step-by-step explanation:
x^3-8 = 0
or, x^3 = 8
or, x = 8×(1/3)
or, x = 2
All solutions to the equation are x = 2, -1 + i√3, and -1 - i√3 two roots are complex and one root is real.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have:
x³ - 8 = 0
Using identity:
a³ - b³ = (a - b)(a² + ab + b²)
(x - 2)(x² + 2x + 4) = 0
x = 2
x² + 2x + 4 = 0
Using quadratic formula:
[tex]\rm x = \dfrac{-2 \pm\sqrt{2^2-4(1)(4)}}{2(1)}[/tex]
x = -1 ± i√3
Thus, all solutions to the equation are x = 2, -1 + i√3, and -1 - i√3 two roots are complex and one root is real.

(48,-30) (61,-45) (74,-60) find the y intercept
Answer:
The y-intercept is about 25.385
Step-by-step explanation:
Calculate slope from difference in y-values divided by difference in x-values.
-15/13 is slope.
Use slope-intercept form.
Y= mx + b
Substitute values from given coordinates for y and x, then solve for b
-60 = -15/13(74) + b
-60 = -85.385 + b
-60 +85.385 = b
25.385 = b

8/3c-2=2/3c-12 solve for c
Answer:
[tex]\boxed {c = -5}[/tex]
Step-by-step explanation:
Solve for the value of [tex]c[/tex]:
[tex]\frac{8}{3}c - 2 = \frac{2}{3}x - 12[/tex]
-Take [tex]\frac{2}{3}c[/tex] and subtract it from [tex]\frac{8}{3}c[/tex]:
[tex]\frac{8}{3}c - 2 - \frac{2}{3}c = \frac{2}{3}c - \frac{2}{3}c - 12[/tex]
[tex]2c - 2 = -12[/tex]
-Add [tex]2[/tex] to both sides of the equation:
[tex]2c - 2 + 2 = -12 + 2[/tex]
[tex]2c = -10[/tex]
-Divide both sides by [tex]2[/tex]:
[tex]\frac{2c}{2} = \frac{-10}{2c}[/tex]
[tex]\boxed {c = -5}[/tex]
So, the value of [tex]c[/tex] is [tex]-5[/tex].
Suppose three riders rode a total of 182 miles. If they used a total of 13 horses, and rode each horse the same number of miles, how many miles did they ride before replacing each horse? They rode _____ miles before replacing each horse. I REALLY NEED HELP
Answer:
They rode 14 miles before replacing each horse
Step-by-step explanation:
We will be working under the assumption that all three riders sat on one horse at a time and rode it while the other horses rested.
From the problem, we can understand that the horses were each ridden for the same distance. This means that to get the total distance a horse rode before it was changed, we can divide the total distance by the number of horses that were used for the journey.
Distance each horse rode = 182/ 13 = 14 miles.
Therefore, each horse was ridden for 14 miles before it was changed.
