Sale amount 399.79 sale tax 5%

Answers

Answer 1

Answer: Sale amount 399.79 sale tax 5%=> 399.79 dollars is the 100% value and the amount of the sales .Now, it is being charged with a 5% sales tax.What we need to do first is to solve for the value of 5% tax, then add it to the amount of the sales.Let's start solving this equation:=> 5% = 5% / 100% = .05=> 399.79 * .05 = 19.99Now, let's add=> 399.79 + 19. 99 = 419.78 dollars will be the new price of the sales.

10. The equation t 0.07c represents the tax, t, based on the cost, c, of an item. Which part of the equation represents the constant of proportionality? Ot 0.07

Answers

The constant of proportionality stays the same no matter what values the variables take, so in our example independently of the cost of the item (and of the tax value, which is dependent on the cost value).

Here the only value that does not change is the 0.007, the rate! - this is the correct answer.

Rachel cut a length of rope 4 and 1/3 meters into two pieces. The length of one piece of rope is 2 and 1/2 meters. what is the length of the second piece of rope

Answers

just do   4 1/3 but first we need to make the fraction'd denominator the same. 6 is     - 2 1/2 the common denominator. so: 4 2/6 =   3 8/6
-------- - 2 3/6 - 2 3/6
   ----------    --------
   1 5/6
1 5/6 meters long
If it is what you wanted please give me brainiest answer!

(4 1/3 m)- (2 1/2 m)= 1 5/6 m.

The length of the second piece of rope is 1 5/6 m~

Using rigid transformations on the trapezoid, build a pattern. Describe some of therigid transformations you used.

Answers

Using rigid transformations on the trapezoid, build a pattern can be made shown in the picture.

What is a trapezoid?

It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.

It is given that:

The trapezoid is shown in the table:

As we know,

The geometric transformation can be defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

After rotating the trapezoid about 180 degrees at the point where 60 degrees angle is formed.

Thus, using rigid transformations on the trapezoid, build a pattern can be made shown in the picture.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

What is an equation of the line that passes through point (8,0) and is parallel to the line x+y=5

Answers

The required equation of the line is y = 8 - x.

Given that,
To determine an equation of the line that passes through the point (8,0) and is parallel to the line x+y=5

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
Given equation,

x+y=5
y = -x + 5
m = -1
Since the slope of parallel lines are equals.
So the equation of the line is given as, which is passing by (8,0)
y - 0 = -1 (x - 8)
y = 8 - x

Thus, the required equation of the line is y = 8 - x.
