Find the value of x.

VMariaS [17]

$\huge{ \bold{ \bigstar \: pythagoras \bigstar}}$

Pythagoras :

${10}^{2} = {x}^{2} + {x}^{2}$

$100 = 2{x}^{2}$

$100 \div 2 = {x}^{2}$

$50 = {x}^{2}$

$x = \sqrt{50}$

$x = \sqrt{25 \times 2}$

$\red{x = 5 \sqrt{2} }$

You are given a cell phone bill. You are charged $52 for the month. There is a $40 monthly fee and you are charged $4 per megab

The equation for the problem is y = 4x + 40. The slope is 4 and the y intercept is 40

The standard equation for a linear equation is given by:

y = mx + b

Where m is the slope of the equation, b is the y intercept, y is a dependent variable and x is the independent variable.

Let x represent the charge per megabyte used and let y represent the total charge for the month

since there is a $40 monthly fee and you are charged $4 per megabyte of data used, hence:

y = 4x + 40

Comparing with the standard linear equation:

The y intercept is 40, this means that even if no data is used, $40 must be paid.

The slope is 4, that is for every megabyte used, $4 is paid.

The amount to pay for 10 MB is:

y = 4(10) + 40 = $80

$80 is paid to use 10 megabytes

I beg help me finish this HW

Answer: The mixed number 16 1/3

Some books write this as 16 & 1/3 to help separate out the whole part (16) and the fractional part (1/3) better.

On paper, you'd write it as $16 \frac{1}{3}$

===========================================================

Explanation:

The three angles mentioned (AOC, DOC, EOD) all combine to form a straight angle AOD = 180 degrees

So we can say,

(angle AOC) + (angle DOC) + (angle EOD) = angle AOD

(angle AOC) + (angle DOC) + (angle EOD) = 180

(7x-2) + (2x+8) + (27) = 180

7x-2 + 2x+8 + 27 = 180

(7x+2x) + (-2+8+27) = 180

9x+33 = 180

9x = 180-33 ... subtract 33 from both sides

9x = 147

x = 147/9 .... divide both sides by 9

x = 16.333333 .... use calculator here

The stuff to the left of the decimal (16) is the whole part

The decimal part 0.33333 where the 3's go on forever converts to 1/3

We can see this if we multiply 0.33333 with 9 getting 0.33333*9 = 2.99997

and that rounds to 3, so 3/9 = 1/3

In short, 16.333333 = 16 & 1/3

Answer:

160 dollars

Step-by-step explanation:

So you would add 6.19 and 9.81 together. Then divide it by 2. You would get 8. Then multiply it by 20 and you would get 160 dollars
