Which is closest to 0.5?
0.4, 0.505, 0.449, 0.48 or 0.53?

Answers

Answer 1
Answer: Let us calculate the nearness of all the numbers provided
Number        Nearnes
0.400                100
0.505                   5
0.449                  51
0.530                30

Thus 0.505 is the closest number to 0.5 in decimal terms
Answer 2
Answer: 1)|0.5-0.4|=0.1\n 2)|0.5-0.505|=0.005\n 3)|0.5-0.48|=0.02\n 4)|0.5-0.53|=0.03

As you see the seconds difference is the smallest therefore 0.505 is closest to .0.5

sales tax and purchase price: suppose the sales tax rate in a certain state is is 8% how much sales tax is charged on a new car if the purchase price is $11,900?

Answers

To calculate the sales tax of an $11,900 purchase, we simply multiply the purchase prices by the sales tax rate.

8% is 8 parts of 100, which can be shown as a fraction with 8/100 or as a decimal with .08

Let's use the decimal in this case:

Sales Tax = purchase price x sales tax rate
Sales tax = 11,900 x .08
Sales tax = $952

So if the car was purchased at $11,900 in a state with an 8% sales tax rate, the sales tax would be $952 bringing the total cost of the car up to $12,852.

Which is bigger 2/5 or 4/9

Answers

The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.

2/5 = 18/45
4/9 = 20/45

Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5

What value of x will make 3x+1=43 true

Answers

3x+1=43

x=14   (divide each side by 3)

the answer is 14

Hi there

3x + 1 = 43
3x = 43 - 1
3x = 42
x= 42/3
x =14

The value of x that will make it true is 14

If the light ray hits a mirror at a 40 degree angle what angle will the ray of light be reflected

Answers

The angle will also be 40 degrees because the reflected ray has the same angle as the incident ray.

What is the reflection of light?

When light rays reflect off a surface, migrate from one transparent medium to another, or travel through a medium whose composition is constantly changing, they change direction.

The angle of the reflected ray is equal to the angle of the incident beam when reflected off a flat surface, according to the law of reflection. (By convention, all angles in geometrical optics are measured with respect to the surface's normal, i.e. a line perpendicular to the surface.)

The reflected ray always falls in the plane specified by the incident light and the surface normal. To comprehend the pictures formed by planar and curved mirrors, the law of reflection can be applied.

As per the question, the light ray hits a mirror at a 40-degree angle.

Thus, the angle will also be 40 degrees because the reflected ray has the same angle as the incident ray.

It will be also 40 degrees as reflected ray has an equal angle to incident ray.
