If a price decreases by 20% I can calculate 20% of the price and subtract it from the original price or I can calculate it in one step and find blank percent of the original price

Answers

Answer 1

Answer:

both statements are fine

Step-by-step explanation:

To find the price of a product after decreasing it, they can be done in the two ways that the statement tells us,

First, calculate that% that was decreased and then subtract it from the original price or simply multiply that original price by the percentage in which the new price would remain.

For example:

let "x" be the original price

in the first case it would be:

0.2 * x and then subtract from x, i.e .:

x - 0.2 * x

in the second case it is:

1 - 0.2 = 0.8

that is, the new price would be 0.8 * x

2. f(3) = 2000

   g(2000) = 45,000

3. g(3,500) = 44,400 and f(6) = 3,500 so the answer is 44,400 - 3,500 = 40,900.

4. From the table when f(x) = 2,500, x = 4.

5. From the table when g(x) = 44,200, x = 4,000.

Answer:

1. when f(x) = $ 3000 the loan still 44,600

2. f(3) means her saving in 3rd month. so f(3) is 2000 then g(2000) is 45000

3. g(3500) - f(6) = 44400 - 3500 = 40,900

The vector v with initial point (0,0) is shown below. Write v in the form v=a i + b j, where a and b are integers.

Answers

Answer:

[tex]v=-3i+5j[/tex]

Step-by-step explanation:

In the representation of a vector we must take into account the coordinate in which its tip is located.

In this case the vector tip is at [tex](-3,5)[/tex] and starts at the coordinate origin.

When expressing a vector in the following form:

[tex]v = ai + bj[/tex]

the numbers [tex]a[/tex] and [tex]b[/tex] represent the components of the vector, that is, the vector measurements when projecting it onto the axes.

The number that accompanies i ([tex]a[/tex]) is the component of the vector on the x-axis, in this case it is 3 units:

[tex]a = -3[/tex]

And the number that accompanies j ([tex]b[/tex]) is the component of the vector in the y-axis, in this case 5:

[tex]b = 5[/tex]

thus, the result is is:

[tex]v=-3i+5j[/tex]

You have 1200 feet of fencing and you want to make two fenced in enclosures by splitting one enclosure in
half. What are the largest dimensions of this enclosure that you could build?

Answers

Let x = length and y = width

You would have 2 lengths, so 2x and 3 widths, so 3y

Those need to equal total length of fence:

2x + 3y = 1200

The 3 widths would equal total fence minus the 2 lengths:

3Y = 1200-2x

Solve for y: y = 400 -2/3x

Area = length x width = xy. Replace y :

Area = x(400-2/3x) = 400x-2/3x^2

Differentiate:

400-4x/3 =0

4x/3 = 400

4x = 1200

X = 300

Y = 400-2/3(300) = 200

The dimension would be 300 ft x 200 ft

Answer:

y + 2 = -2(x - 3)^2

Step-by-step explanation:

We can see immediately that the vertex is at (3, -2).  

The vertex form of the equation of a parabola is

y - k = a(x - h)^2.

If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2.  But seeing that this particular parabola opens downward, the equation is

y + 2 = -2(x - 3)^2.

Check:  Does the point (2, -4) satisfy this equation?

-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.

Given the equation,D=m/v if D=6/7 and =m+3 then m=.

Answers

Answer:

[tex]m=18[/tex]

Step-by-step explanation:

The equation given is [tex]D=\frac{m}{v}[/tex]

and also we have that [tex]D=\frac{6}{7}[/tex], thus:

[tex]\frac{6}{7}=\frac{m}{v}[/tex]

------------

I think the question is missing which variable is defined as [tex]=m+3[/tex], so I will solve for [tex]v=m+3[/tex] since is the only other variable in the equation.

substituting [tex]v=m+3[/tex]  into [tex]\frac{6}{7}=\frac{m}{v}[/tex]:

[tex]\frac{6}{7}=\frac{m}{m+3}[/tex]

and we solve for m:

[tex](m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m[/tex]

m is equal to 18.

Answers

Answer:

The correct option is (B) 69.7%.

Step-by-step explanation:

The table provided represents the probabilities of a positive response to two government programs from citizens in eight cities.

The probabilities mentioned in the table are conditional probabilities, i.e. the probability of a positive response for program 1, given that the individual is from city x.

The probability a positive response for program 1 from an individual from Houston is 69.7%.

Then the conditional probability of a positive response for program 1, given that the individual is from Houston is 69.7%.

Thus, the correct option is (B).

Sidney is eating lunch at a salad bar where you create your own salad. An 8-ounce salad costs $2.49. Each additional ounce of salad costs $0.25. How much does Sidney's salad cost if it weighs 1 pound, 8 ounces?

Answers

Answer:

6.49

Step-by-step explanation:

2.49 + 0.25(16)

2.49+4

6.49

Answer:

$6.49

Step-by-step explanation:

1 lb = 16 oz

His salad weighs 1 lb, 8 ounces which is the same as 16 ounces plus 8 ounces.

8 ounces cost $2.49

His salad weighs 16 ounces more than 8 ounces, so in addition to the $2.49, he needs to pay $0.25 per ounce for 16 extra ounces.

16 * 0.25 = $4.00

Total cost = $2.49 + $4.00 = $6.49

The bottom part of this block is a rectangular prism. The top part is a square pyramid. You want to cover the block entirely with paper. How much paper do you need?

Answers

Answer:

Total paper required = 165 cm²

Step-by-step explanation:

Paper required to cover the entire block = (Surface area of the prism at the base - area of the top of the prism) + Lateral surface area of the pyramid

Surface area of the rectangular prism = 2(lb + bh + hl)

(here l, b, h are the length, width and height respectively)

                                                               = 2(5×5 + 5×4 + 4×5)

                                                               = 2(25 + 20 + 20)

                                                               = 2×65

                                                               = 130 cm²

Area of the top of the prism = (side)²

                                              = 5²

                                              = 25 cm²

Lateral area of the square pyramid = 4 × Area of one lateral side

                                                          = 4 × [tex][\frac{1}{2}(\text{Base})(\text{Height})][/tex]

                                                          = 4 × [tex][\frac{1}{2}(5)(6)][/tex]

                                                          = 60 cm²

Total paper required = (130 - 25) + 60

                                   = 105 + 60

                                   = 165 cm²

The orchestra tickets cost $2 more than the mezzanine tickets, while the mezzanine tickets cost $1 more than the balcony tickets. Twice the cost of an orchestra ticket is $1 less than 3 times the cost of a balcony ticket. Determine the price of each kind of ticket.

Answers

Answer: an orchestra seating ticket cost $10

A mezzanine seating ticket cost $8

A balcony seating ticket cost $7

Step-by-step explanation:

Let x represent the price of an orchestra seating ticket.

Let y represent the price of a mezzanine seating ticket.

Let z represent the price of a balcony seating ticket.

The orchestra tickets cost $2 more than the mezzanine tickets. It means that

x = y + 2- - - - - - - 1

The mezzanine tickets cost $1 more than the balcony tickets. It means that

y = z + 1 - - - - - - -2

Twice the cost of an orchestra ticket is $1 less than 3 times the cost of a balcony ticket. It means that

2x = 3z - 1- - - - - - - - -3

Substituting equation 2 into equation 1, it becomes

x = z + 1 + 2

x = z + 3 - - - - - - - - - -4

Substituting equation 4 into equation 3, it becomes

2(z + 3) = 3z - 1

2z + 6 = 3z - 1

3z - 2z = 6 + 1

z = 7

x = z + 3 = 7 + 3

x = 10

y = z + 1 = 7 + 1

E. Log(2)/log(7)

Answers

Answer:

D

Step-by-step explanation:

Using the changing base formula, log base 2 raised to 7 can be written as log7/log2

The correct answer is D. log(7) / log(2).

To find the equivalent of log2(7), you can use the change of base formula for logarithms.

The change of base formula states that log base a of b is equal to log base c of b divided by log base c of a.

In this case, we want to find the equivalent of log2(7), so we can use the change of base formula with base 10 as follows:

log2(7) = log(7) / log(2)

Therefore, the correct answer is D. log(7) / log(2).
