Answer:

6√2

Step-by-step explanation:

A 45 45 90 right triangle, so ratio of leg : leg: hypotenuse = a: a : a√2 (a = value of leg)

Given: leg = 6

So the ratio of leg : leg: hypotenuse = 6 : 6 : 6 √2

Answer:

x = 6√2

Answer:

B

Step-by-step explanation:

Since the triangle is right use the sine ratio to solve for x

and the exact value for sin45° = \frac{1}{\sqrt{2} }, then

sin45° = \frac{opposite}{hypotenuse} = \frac{6}{x}

Multiply both sides by x

x × sin45° = 6 ( divide both sides by sin45° )

x = \frac{6}{sin45} = \frac{6}{\frac{1}{\sqrt{2} } } = 6\sqrt{2}

A washer and a dryer cost $847 combined. The washer costs $53 less than the dryer. What is the cost of the dryer?
Natalija [7]
--------------------------------------------------------------
Define x :
--------------------------------------------------------------
Let the dryer be x.
Dryer = x 
Washer = x -53

--------------------------------------------------------------
Construct Equation :
--------------------------------------------------------------
The washer and the dryer cost $847
⇒ x + x - 53 = 847

--------------------------------------------------------------
Solve x :
--------------------------------------------------------------
x + x - 53 = 847
2x - 53 = 847
2x = 847 + 53
2x = 900
x = 450

--------------------------------------------------------------
Find cost of dryer and washer :
--------------------------------------------------------------
Dryer = x = $450
Washer = x = 450 - 53 = 397

--------------------------------------------------------------
Answer: Dryer = $450

Where do I place the coordinates for -2x-5 and -x-4
Maslowich

Step-by-step explanation:

you need to calculate coordinates first. just by having the function definitions you don't have any coordinates yet.

I typically pick x = 0 as a first point.

so, that gives

-2×0 - 5 = -5

as y result for the first line.

the point on line 1 is then (0, -5)

and we get -0 - 4 = -4 as y result for the second line.

the point for the second line is (0, -4)

for second points I typically go for x = 1.

for the first line we get

-2×1 - 5 = -2 - 5 = -7

and the second point is (1, -7) for the first line.

for the second line we get

-1 - 4 = -5

and the second point is (1, -5) for the second line.

so, make points on the chart for all 4 points, and connect them (and extend the connecting lines to the left and right to the end of the grid).

and the crossing point ?

that is where both equations deliver the same result.

so,

-2x - 5 = -x - 4

-x = 1

x = -1

and the y is then e.g. -2×-1 - 5 = 2 - 5 = -3

and the crossing point is (-1, -3)

The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x
Hunter-Best [27]

For this case we give as data the following equation:

4x + 12 = 48

Where "x" represents the cost of a ticket.

By clearing the value of "x" of the equation we can know the cost of a ticket.

If we subtract 12 from both sides of the equation, we have:

4x = 48-12\\4x = 36

If we divide between 4 on both sides of the equation:

x = \frac {36} {4}\\x = 9

Therefore, the cost of a ticket is $ 9.00
