Answers

Answer 1

Jessica purchased a DVD that was on sale for 12% off.

The sales tax in her county is 3%.

Let, y represent the original price of the DVD.

We can simply solve this mathematical problem by using the following mathematical process.

Here, we will form an algebraic expression, according to the given data.

So,

The original price of the DVD = y

Discount on the original price :

y * 12/100

=3y/25

Price after discount :

y - 3y/25

=25y - 3y/25

=22y/25

Sales tax amount :

22y/25 * 3/100

11y/25 * 3/50

=33y/1250

Final price including the sales tax :

22y/25 + 33y/1250

1100y + 33y/1250

1133y/1250

(This will be considered as the final result.)

3n=3(n)

ur replcing n with 2

3(2)=3x2

3x2=6

Answer:

Step-by-step explanation:

3n means you are multiplying 3 and n. since n = 2, the only thing you need to do is plug in 2 for n and then simplify by multiplying 3 · 2.

I milliliters
х
5
?

Answers

Answer:

44.1mm

Step-by-step explanation:

Given

Total solution of acis nad water = 329mm

Percentage that is acid = 13.4%

Amount that is acid = 13.4% of 329

Amount that is acid = = 13.4/100 * 329

Amount that is acid = 13.4*3.29

Amount that is acid = 44.086

Hence the amount of acids there is 44.1mm

The area of a triangle A is given as A =1/2 bh, where b is the base an h = height. (a) find h if A =30 and b=10

Answers

Answer:

h = 6

Step-by-step explanation:

Substitute the given to its corresponding places.

30 = [tex]\frac{1(10)h}{2}[/tex]

30 = 10h/2

Multiply both sides by two to remove the denominator.

2 [30 = 10h/2] 2

60 = 10h

Divide both sides by 10 to isolate h.

h = 6

To check, substitute everything to the original equation:

A = [tex]\frac{1(10)(6)}{2}[/tex]

A = 30 !
