a dress is regulary price a $45 thedress is marked down 30 percent what is sale price of the dress

Answers

Answer 1

Answer:

$31.50

Step-by-step explanation:

So first thing, it's necessary to figure out what 30% of 45 is.

You can set this up as an algebraic expression or your can multiple 45 by 3/10 to find out what that 30% is.

The algebraic expression would be 30% of 45 is x.

Using one of these two options; we would discover that 30% of 45 is 13.5.

However, this is not the answer, yet.

The question is looking for the price of the dress after the 13.5 is taken away.

Therefore, you would subtract.

45 - 13.5 = 31.5

Sooooo... your answer is "The sale price of the dress is $31.50."

Answers

Answer:

Step-by-step explanation:

according to PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) you would do 12 minus 6 first resulting in the answer of 6 so your equation would then be 5 x 6 divided by 2. 5 x 6 comes next in the equation and thats 30 so your new equation is 30 divided by 2. 30 divided by 2 is 15.

MonarchAOP.com

Answers

Answer:

One number is 10 less than twice another.

This translates to n=2m-10

Their difference is 31

This translates to n-m=31

n-m=31

(2m-10)-m=31

m-10=31

m=41

n-41=31

n=72

Therefore the larger number is (B) 72

9. The temperature of a liquid that is increasing can be represented by the equation
f(t) = 64 + 4t, where t is the time in hours. Graph the function to show the temperatures over the
first 10 hours. Use the graph to estimate the temperature after 7 hours.

Answers

Answer:

92°F

Step-by-step explanation:

in degrees Fahrenheit,

t=7

f(7)=64 + 4(7)

=92

The required temperature of liquid after 7 hours is 92.

Given that,
The temperature of a liquid that is increasing can be represented by the equation f(t) = 64 + 4t, where t is the time in hours. Graph the function to show the temperatures over the first 10 hours. To use the graph to estimate the temperature after 7 hours.

What is a graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
f(t) = 64 + 4t
T = 7
f(7) = 64 + 4 * 7
= 64 + 28
= 92

Thus, the required temperature of liquid after 7 hours is 92.

Armed guards systematically paced around the room. Long tables with low metal dividersseparating the visitors from the visited were the only furnishings. The prisoners were marched in dressedin orange or blue jumpsuits, or gray sweat suits with "DOC" emblazoned across the chests. The uniformsreinforced the myriad other signals around us: the prisoners were owned by the state. Lucky inmateswere allowed to sit across regular tables from loved ones.
