Something on sale for $725. The original price was $1299. To the nearest tenth of a percent, what was the rate of discount?
ElenaW [278]

Answer:

44.2%

Step-by-step explanation:

Rate of discount = (difference in prices / original price) x 100

Difference in price = $1299 - $725 = $574

Original price = $1299

($574 / $1299) x 100 = 44.187837%

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

the hundredth figure is 8, which is greater than 5. 1 would be added to the tenth figure.

So it becomes 44.2%

5sin²α+3cos²α / 3sin²α-5cos²α = <br> if tgα=√2
fiasKO [112]
Tgα = tan(α) = sqrt(2)/1 = opposite/ adjacent
opposite = sqrt(2)
adjacent = 1
hypotenuse = sqrt(opposite^2 + adjacent^2)
= sqrt(sqrt(2)^2 + 1^2) = sqrt(3)

sin(α) = opposite/hypotenuse
= sqrt(2)/sqrt(3)

cos(α) = adjacent/hypotenuse
= 1/sqrt(3)

now we can calculate the value of
5sin²α+3cos²α / 3sin²α-5cos²α
... do the math

How do you write this in numerical expression and in a answer statement
-Dominant- [34]
To write this as a numerical expression, you will think of the different parts of the math story that are occurring and put them together in one math statement.  You have 12 books being ordered that are $9 each AND are paying a $15 shipping charge.  This can be written as 12 x $9 + $15.  There are 2 terms here - these are the 2 parts!  Multiply 12 times 9 first to get $108, then you can add the $15 shipping fee.  You can only add units that are the same, so you must multiply first. Your answer statement is a sentence that gives your final answer in a complete sentence.  For example, the total cost of Lannie's order is $123.
