Answer:

The correct answer is B. point

Step-by-step explanation:

We know that a line has a length so option a cannot be correct.

A point is represented by a dot which has no length, width and height.

A ray is formed by a collection of points which altogether make its length.

Similarly an angle is formed by two rays.

So, angle, ray and line, all of them have length, width or height.

Hence, B. Point is the right answer ..

Five years ago, a typical 70” TV cost about $2400. Now a similar TV costs approximately $1680. What is the percent decrease in T

Archy [21]

Answer:

The percentage decrease in TV price after five years is 6.89

Step-by-step explanation:

Given as :

The cost of TV five years ago = $ 2400

The present cost of TV = $ 1680

Let The decrease percentage in five years = x

So, The cost of TV after T year = Present cost × $(1-\frac{Rate}{100})^{Time}$

Or, $ 1680 = $ 2400 × $(1-\frac{Rate}{100})^{5}$

Or, 0.7 = $(1-\frac{Rate}{100})^{5}$

Or, $(0.7)^{\frac{1}{5}}$ = 1 - $\frac{x}{100}$

Or, 0.9311 = 1 - $\frac{x}{100}$

Or, $\frac{x}{100}$ = 1 - 0.9311

∴, $\frac{x}{100}$ = 0.0689

I.e x = 0.0689 × 100 = 6.89

Hence The percentage decrease in TV price after five years is 6.89 Answer

What is 3/4 + 1/2 inches

zzz [600]

Answer:3/4+1/2 = 1 1/4

Step-by-step explanation:

First you want the denominators ( the bottom numbers ) to be the same so you have to find the lowest common denominator, which is four.

3/4+2/4= 5/4, or 1 1/4 or 1.25 the second fraction is changed to 2/4 which is the equivalent of 1/2.
