Let p be the percent decrease in the price of a DVD recorder that is marked down from $500 to $400. Which proportion can be used

Effectus [21]

The correct answer is C. $400-$500/$500=p/100.

The formula for percent change is as follows.

New - Old/ Old = Percent change.

With 500 being the old score, we would look for it to be subtracted and on the bottom. C is the only option that has that.

A relative frequency table is made from data in a frequency table.

Dafna11 [192]

Answer:

k = 11 let me know if you don't understand how I got this.

Step-by-step explanation:

I'm gonna write it out

U V total

S 26 42 68

T 21 k 32

Total 47 53 100

So, you want to look at the column and row labeled total, this is the key. for the row total, it sums up everything in the column above it. so for the u column, the total value is 47 while the two values above it are 26 and 21. These two values sum to 47. This is the same for all other columns, and you can use the same reasoning with the total column as well summing rows.

This gives you two ways to solve for k. either 21 + k = 32 or 42 + k = 53. Either way gets you the answer k = 11

How do you find the solution of an inequality using a graph?.

Oksi-84 [34.3K]

To graph an inequality, consider the < or > sign to be a = sign and graph the equation. If the inequality is < or >, draw a dotted line to represent the equation.

Graph the equation as a solid line if the inequality is ≤ or ≥, This line divides the xy-plane into two regions: one that meets the inequality and one that does not.

When inequalities are graphed on a coordinate plane, the solutions are found in a region of the plane that is shaded. If the points on the line satisfy the inequality, as in the case of and, the boundary line for the inequality is drawn as a solid line.

Linear inequalities are not the same as linear equations, but what you know about equations can help you understand inequalities. Equations and inequalities are both mathematical statements that compare two values.

You have two pieces of string. One is 8 cm long. The other is 20 centimeters long. You want to cut each piece if string into sma

Minchanka [31]

ah, basically what length can you divide each string to get a certain length

factor each

8=2*2*2

therefor:

8=1*8=2*4=4*2=8*1

so you can have 1 length of string 8cm long

2 lengths of string 4cm long

4 lengths of string 2cm long

8 lengths of string 1cm long

20cm string

factor

20=1*2*2*5

so 20=1*20=2*10=4*5=5*4=10*2=20*1

you can have 1 string 20cm long

2 strings 10cm long

4 strings 5cm long

5 strings 4cm long

10 strings 2cm long

20 strings 1cm long

we need greatest common length

in 8cm stirng, we have 1,2,4,8

in 20cm string, we have 1,2,4,5,10,20

greatest common length is 4

answer is 4cm

alternately, you could have done this:

8=2*2*2

20=2*2*5

common grooup is 2*2=4 so 4 is answer

Solve to find x and y in the diagram.

Kipish [7]

Considering the given information in the question, the value of x is $12^{o}$ , and that of y is $7.5^{o}$ .

A transversal is a line that cuts through two given parallel lines. Thus it intersects each parallel line at a point, forming four angles each.

From the given information in the question, it can be inferred that:

the given bottom right angle of the first intersection and the bottom right angle with the second intersection are congruent (corresponding angle property).

So that,

$(5x+4y)^{o}$ = $(12y)^{o}$
