What is P vs NP?? Give an example?

Answer:

D y=50x + 25

Step-by-step explanation:

The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.

Answer:

D

Step-by-step explanation:

y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)

That means the equation is y = 50x + 25

Answer:

hello :

the perimeter is : p = 2 ( w + l )

The area is : A= w ×l       w : width       l : length       w ?

2 ( w + l )  = 76

w ×l  = 336

you have the system :

w + l = 38 ...(1)

w ×l  = 336...(2)

by (1) : l = 38 - w

subst in (2) : w ( 38 - w ) =336

38w - w²= 336

w² - 38w +336 = 0

delta = b² -4ac     when : a = 1   and  b= -38      c = 336

delta = (-38)² -4(1)(336) = 1444 - 1344  = 100 = 10²

w1 = (38-10)/2 = 14( the shorter sides length)

w2 = (38+10)/2 = 24( refused  )

The shorter side's length of the rectangle is 24 inches. This is determined by solving the system of equations derived from the area (336 square inches) and perimeter (76 inches) constraints, resulting in a quadratic equation with two possible solutions, and the shorter side being 24 inches.

• To find the shorter side's length of a rectangle with an area of 336 square inches and a perimeter of 76 inches, we'll use a system of equations.
• Let's denote:
• Length of the rectangle as L (in inches).
• Width of the rectangle as W (in inches).
• We have two pieces of information:
• The area of the rectangle is 336 square inches:
• L * W = 336
• The perimeter of the rectangle is 76 inches:
• 2L + 2W = 76
• Now, we can solve this system of equations for L and W.
• First, isolate L in the perimeter equation:
• 2L + 2W = 76
• 2L = 76 - 2W
• L = (76 - 2W) / 2
• L = 38 - W
• Now, substitute this expression for L into the area equation:
• (38 - W) * W = 336
• Expand and rearrange the equation:
• 38W - W^2 = 336
• Move all terms to one side to create a quadratic equation:
• W^2 -
• Now, we can solve this quadratic equation for W. We can either factor it or use the quadratic formula. In this case, let's use the quadratic formula:
• W = (-b ± √(b² - 4ac)) / (2a)
• Where:
• a = 1 (coefficient of W^2)
• b = -38 (coefficient of W)
• c = 336
• W = (-(-38) ± √((-38)² - 4 * 1 * 336)) / (2 * 1)
• W = (38 ± √(1444 - 1344)) / 2
• W = (38 ± √100) / 2
• W = (38 ± 10) / 2
• Now, we have two possible values for W:
• W = (38 + 10) / 2 = 48 / 2 = 24 inches (shorter side)
• W = (38 - 10) / 2 = 28 / 2 = 14 inches (longer side)
• So, the shorter side's length is 24 inches.

Final answer:

The original price of the notebook that Fernando paid for was $600. This is calculated by dividing the discount price of $450 by 0.75.

Explanation:

The question is about calculating the original price of an item from a given discount price. If $450 represents 75% of the original price, we can set up an equation to solve for the original price.

The equation can be set up as follows: 0.75x = $450.

To solve for x, which is the original price, we need to divide $450 by 0.75.

The calculation will be as follows: $450/0.75 equals $600, which is the original price. So, the original price of the notebook was $600.

Hope it helps ❤️

Final answer:

Yes, 2/5 is greater than 0.55.

Explanation:

Yes, 2/5 is indeed greater than 0.55.

To compare the two fractions, we can convert the decimal 0.55 into a fraction. This can be done by dividing 0.55 by 1, since any number divided by 1 is equal to itself. Hence, 0.55 is equivalent to 0.55/1.

Now, we can compare 2/5 and 0.55/1. To do this, we can find the common denominator, which is 5. Multiplying the numerator and denominator of 0.55/1 by 5 gives us 2.75/5.

Since 2.75/5 is greater than 2/5, we can conclude that 2/5 is greater than 0.55.
