Un carpintero quiere cortar una hoja de madera de 256 cm de largo y 96 cm de ancho, en cuadrados lo más grandes posible. A) ¿Cuál debe ser la longitud del lado de cada cuadrado? B) ¿Cuántos cuadrados se obtienen de la plancha de madera?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the dimension :
256 cm by 96 cm
To know the largest number of possible squares obtainable, we calculate the Greatest common factor of 256 and 96
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
96 : 2, 3, 4, 6,, 8, 16, 32, 48, 96
The greatest common factor is 32
Hence, length of side of each square = 32cm
Number of squares obtained :
Area of rectangle :
Length * width
256cm * 96cm 24,576cm²
Area of square :
s² ; s = side length
32² = 1024cm²
Number of squares :
24,576cm² / 1024cm²
= 24 squares

Step-by-step explanation:
Given: 3x - 14 = 43
Prove: x = 19
Step-by-step explanation:
Because you're trying to prove the value of X, you work backwards. here's what you do
When working backwards, PEMDAS becomes SADMEP
First, add 14 to 43 (57).
Then, divide 57 by 3 to get 19.
x = 19!
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 14 to both sides of the equation:
3x - 14 (+14) = 43 (+14)
3x = 43 + 14
3x = 57
Next, divide 3 from both sides of the equation:
(3x)/3 = (57)/3
x = 57/3
x = 19
~
Proof: Plug in 19 for x in the equation for x:
3(19) - 14 = 43
First, multiply:
(3 * 19) - 14 = 43
(57) - 14 = 43
Next, subtract:
57 - 14 = 43
43 = 43 (True).

Complete Question
Marissa found a shirt that had a 20% markdown on it if the price of the shirt is represented by x how much does the shirt cost excluding tax select all that apply
select all that apply
A. 0.20x
B.0.80x
C.x-0.20
D.x-0.80x
E.x(0.2+1.00)
F. x(1.00-0.20)
Answer:
B. 0.80x
F. x(1.00-0.20)
Step-by-step explanation:
The Formula for Selling Price when you have percent markdown is;
Selling price = (1 - percentage mark down)× Original price
From the question:
Selling price= Cost of the shirt(excluding tax)
Original price = x
Percentage markdown = 20%
= 0.20
Hence,
Cost of the shirt(excluding tax)
= (1 - 20%)x
= (1 - 0.20)x
= 0.80x

Thomas went to the store to buy video games for $13.50 each and controllers that cost $55 each. Write and equation where c represents the total cost, g is the number of games he bought, and p is the number of controllers he bought.
Answer:
c = 13.50g + 55p
Step-by-step explanation:
You multiply the cost of the item by the amount you bought.
An equation for the total cost of video games and controllers is c = 13.50g + 55p.
Given that, Thomas went to the store to buy video games for $13.50 each and controllers that cost $55 each.
We need to write an equation where c represents the total cost, g is the number of games he bought, and p is the number of controllers he bought.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, the total cost of video games=13.50g
The total cost of controllers=55p
Total cost =c = 13.50g + 55p
Therefore, an equation for the total cost of video games and controllers is c = 13.50g + 55p.

Janice put $5823.00 into a savings account that pays 2.25% interest.If she leaves that money in the account for 4 years,how much will the balence of her account be?
Given:
Principal value = $5823.00
Rate of interest = 2.25%
Time = 4 years
To find:
The amount in the account after 4 years.
Solution:
The formula for amount is
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
where, P is principal, r is rate of interest and t is time period.
Putting P=5823, r=2.25 and t=4 in the above formula.
[tex]A=5823\left(1+\dfrac{2.25}{100}\right)^4[/tex]
[tex]A=5823\left(1+0.0225\right)^4[/tex]
[tex]A=5823\left(1.0225\right)^4[/tex]
[tex]A=5823(1.0930833)[/tex]
[tex]A=6365.0240559[/tex]
[tex]A\approx 6365.024[/tex]
Therefore, the amount in the according after 4 years is about $6365.024.
