Answer:

<em>The total percentage discount was 19%</em>

Step-by-step explanation:

<u>Percentages</u>

Suppose the original price of the shirt was x.

A discount of 10% reduces the price by:

10*x/100 = 0.1x

Thus, the discounted price is:

x - 0.1x = 0.9x

The second discount reduces the price by:

10*0.9x/100 = 0.09x

The new discounted price is:

0.9x - 0.09x = 0.81x

With respect to the original price, the last discounted price has been discounted by:

x - 0.81x = 0.19x

This means the total percentage discount was 0.19*100 = 19%.

The total percentage discount was 19%

Vlada [557]
Weekend just includes Saturdays and Sundays, so you don't have to count the earnings on Friday. You simply have to count the number of hours that passed from 7 am to 11 pm on Saturday. That would be a total of 16 hours. While on Sunday, the time from 9 am to 9 pm is a total of 12 hours. Hence, the total time would be 16 hours + 12 hours = 28 hours

Question 1
MAVERICK [17]
Question 1:
x - Tim`s age,  y - Coach Johnson`s age:
x + 10 = y
2 * ( x - 3 ) = y - 3
-----------------------
2 x - 6 = x + 10 - 3
2 x - x = 7 + 6
x = 13
Tim is 13 years old.
Question 2:
x - 62,500 = 0.25 * 125,000
x - 62,500 = 31,250
x = 31,250 + 62,500
x = 93,750

Which equations show direct variation between a and b? Choose all answers that are correct.
djyliett [7]
A.) b = 0.7a
d) 1a = b

These two equation shows the direct variation. with the coefficient of a as the constant of variation.

y = kx ; where k is the constant of variation. y directly varies with x at the rate of k.

b = 0.7a   where b represents y ; a represents x; and 0.7 represents k.
1a = b where b represents y ; a represents x ; and 1 represents k.

Line /is the segment bisector of PQ. What is the value of x? Round your answer
Valentin [98]

Answer:

x = 2.6

Step-by-step explanation:

Here we have that line l is the bisector of segment PQ.

According to the definition of bisector, this means that line l cuts the segment PQ into two parts of equal length.

This means that the length of PM must be equal to the length of MQ. So we can write:

|PM|=|MQ|\\5x-7=11-2x

Now we have to solve the equation to find x. First, we add +7 on both sides:

5x-7+7=11-2x+7\\5x=18-2x

Now we add +2x on both sides:

5x+2x=18-2x+2x\\7x=18

And therefore,

x=\frac{18}{7}=2.6
