18.50 times 20% equals 3.7 as 20%, so 18.50-3.7=14.8

So
20% of 18.50 = ____ 

to get this you multiply 
20% is .20 in decimal form 

18.50 x .20 = $3.70 

so 20% is $3.70, which means the discount is $3.70 

so then you subtract $3.70 from the original price of 18.50 and you get 

$14.80 which is your answer (:

The city of Yorkton, Saskatchewan, has an area of 24.0 km^2. If this city were a perfect square, what would it’s exact perimeter

Elis [28]

Answer:

8 $\sqrt{6}$ inches

Step-by-step explanation:

Let l represent the length of the square

The area of a square = l^2

That means,

l^2 = 24 km^2

Take the square root of both sides

l = $\sqrt{24}$

l = $\sqrt{4*6$

l = $\sqrt{4} *\sqrt{6}$

l = 2 $\sqrt{6}$

Now lets find the perimeter

Perimeter of a square, P = 4l

P = 4* 2 $\sqrt{6}$

P = 8 $\sqrt{6}$ inches

At East Middle School, there are 585858 left-handed students and 609609609 right-handed students. The numbers of left- and right

lisabon 2012 [21]

Answer: C. Left-handed: 48 Right-handed: 504

E. Left-handed: 30 Right-handed: 315

Step-by-step explanation:

Here is the completed question:

At East Middle School, there are 58 left-handed students and 609 right-handed students. The numbers of left- and right-handed students at West Junior High are proportional to the numbers at East Middle School. Which of the following could be the numbers of left-handed and right-handed students at West Junior High?

A. Left-handed: 42 Right-handed: 483

B. Left-handed: 28 Right-handed: 378

C. Left-handed: 48 Right-handed: 504

D. Left-handed: 56 Right-handed: 560

E. Left-handed: 30 Right-handed: 315

Since it's direct proportion, we have to calculate the constant of proportionality which will simply be:

= 609 / 58 = 10.5

A. Left-handed: 42 Right-handed: 483

Constant = 483/42 = 11.5

Incorrect

B. Left-handed: 28 Right-handed: 378

Constant = 378/28 = 13.5

Incorrect

C. Left-handed: 48 Right-handed: 504

Constant = 504/48 = 10.5

Correct

D. Left-handed: 56 Right-handed: 560

Constant = 560/56 = 10

Incorrect

E. Left-handed: 30 Right-handed: 315

Constant = 315/30 = 10.5

Correct

Therefore, the correct options are C and E.

Law of reflection. Easy question please help (picture included)

PIT_PIT [208]

Simple. The Law of Reflection states that the angle of incidence is equal to the angle of reflection. These two angles are measured relative the normal line (line perpendicular to the surface). The angle of reflection is therefore 34 degrees also. However, since the question is asking for the angle relative to the mirror, then the answer is 90-54 = 36° Thus your answer is C. 36°
