The cost of a pair of pants was reduced from $50 to $40. By what percent did the cost of the pair of pants decrease? 2% 10% 20% 40%

Answers

Answer:

C. 20%

Step-by-step explanation:

50*2=100

40*2=80

100-80=20

A percentage is a number or ratio that represents a fraction of 100. 

The percentage decrease in the cost of the pair of pants is 20%.

What is a percentage?

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50/100 = 1/2

10% = 10/100 = 1/10

25% = 25/100 = 1/4

20% = 20/100 = 1/5

We have,

The initial cost of pair of pants = $50

The final cost of pair of pants after reduced = $40

The percentage decrease in the cost of pair of pants:

= [( Initial cost - Final cost ) / Initial cost] x 100

= [(50 - 40) / 50] x 100

= (10/50) x 100

= 20%

Thus,

The percentage decrease in the cost of the pair of pants is 20%.

The factored form of a quadratic function is f(x)=(x-p)(x-q).The standard form of a quadratic function is fX)=ax^2+bx+c. The factored
form for a quadratic function tells us the x-intercepts of the quadratic function, while the standard form for a quadratic function tells us they
intercept of the quadratic function.
If p=2 and q=-3, use what you have learned about multiplying polynomials to
1) write the factored form of the quadratic function f(x)
2) write the standard form for the quadratic function f(x)

Answers

Answer:

(1) f(x)=(x-2)(x-3)

(2) f(x)=x²-5x+6

Step-by-step explanation:

(1) f(x)=(x-p)(x-q)

   f(x)=(x-2)(x-3)

(2) f(x)=x²-3x-2x+6

    f(x)=x²-5x+6

The Walter family budgets a maximum amount of $124 for a camping trip.
Mr. Walter already spent $40. How many people x can go canoeing if the
cost is $21 per person?
A- 21x + 40 >_ 124
B- 21x + 40 <_124
C- 40x + 21 < _124
D- 21x + 40 > 124

Answers

Answer:

B. 21x + 40 ≤ 124

Step-by-step Explanation:

Maximum amount budgeted = $124 (this means they can't spend more than this)

x = number of people

Cost per head = $21

Given that Mr Walter already spent $40, which is part of the money budgeted, the number of people that can go canoeing cam be expressed with the following inequality:

21x + 40 ≤ 124

(note: the amount total to be spent will either be equal to or greater than $124, because it's the maximum amount budgeted for spending).

Working simultaneously, four fudge machines complete a big order in 32 hours. All the machines at the fudge factory work at the same pace. a If only half of the machines are working, in how many hours will the order be complete?

Answers

If only half the machines are working at the same rate as before, the order will be finished in 64 hours.

When the four big fridges were working simultaneously, they were able to finish the order in 32 hours.

With only half of these fridges, they will only be half as fast. This means that they will complete the order in double the time:

= 32 x 2

= 64 hours

In conclusion, the order will be completed in 64 hours.

Answers

The correct answer for the given subtraction is:

3.5 - 2.46 = 1.04

How to solve the subtraction?

Here we want to find the subtraction between two numbers in decimal form:

3.5 - 2.46 = 1.16

Now, this is clearly wrong, as 0.46 is smaller than 0.5, so the decimals after the decimal point are incorrect, now let's solve it again.

First, we can rewrite these two numbers as:

3.5 = 3 + 0.5

2.46 = 2 + 0.46

Then the subtraction can be rewritten as:

3.5  - 2.46

(3 + 0.5) - (2 + 0.46)

Now we group like terms:

(3 - 2) + (0.5 - 0.46)

1 + (0.50 - 0.46)

1 + (0.04)

Now we group that, so we get:

1 + (0.04) = 1.04

This is the correct answer to the given subtraction.
