<u>Answer:</u>
The total amount that Eunice paid is $1027.2
<u>Explanation:
</u>
Given the price of the couch is $1200
She was charged a sales tax of 7% and got a discount of 20% because the store was having a sale
Price after sales tax and discount can be calculated
by the formula =
Solving,
= $1027.2
Therefore, Eunice paid a final price of $1027.2 after tax and discount.
These are both rational numbers, because they are (our could be written as) a fraction. 1.45 = 145/100
There is no smaller subset of real numbers that works, because the next smaller subset is integers, but these aren’t integers.
The answer is 5x + 10 because you have to times 5 by everything in the parenteses
Answer:
40°
Step-by-step explanation:
Ratio of two supplementary angles = 2 : 7
The angles are 2x , 7x
2x + 7x = 180 {Supplementary}
9x = 180
x = 180/9
x = 20
Acute angle = 2x = 2*20 = 40
Basically, you're solving a proportion.
the proportion would be:
40/100 = 10/x
40 goes over 100 since it's a percent, and 10 and 40% are equal since 10 of the students in the art class represent 40% of the total number of students. X represents the missing info, which is the total number of students.
Now, you just cross multiply:
40(x) = 40x
10(100) = 1000
Since that's done, you now divide 1000 by 40, which equals 25.
There are 25 students in the art class :)
