A computer monitor is 23 inches which is the diagonal distance across the screen.If the screen measures 13 inches in height,what is the actual width of the screen to the nearest inch?

Answers

Answer:

width = 19 inches

Step-by-step explanation:

Pythagorean theorem

23^2 = 13^2+x^2

529 = 169+x^2

x^2 = 360

x = 18.97

The actual width of the screen to the nearest inches will be 18.97 inches.

What is a Pythagoras theorem?

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

A PC screen is 23 inches which is the slanting distance across the screen.

If the screen measures 13 inches in height. Then the actual width of the screen will be given as,

23² = 13² + B²

529 = 169 + B²

B² = 360

B = √360

B = 18.97 inches

The actual width of the screen to the nearest inches will be 18.97 inches.

16x^2 + 10x — 27 = -6x + 5

What are the solutions to this equation?

Answers

Answer:

x=1 or x=−2

Step-by-step explanation:

16x2+10x−27=−6x+5

Step 1: Subtract -6x+5 from both sides.

16x2+10x−27−(−6x+5)=−6x+5−(−6x+5)

16x2+16x−32=0

Step 2: Factor left side of equation.

16(x−1)(x+2)=0

Step 3: Set factors equal to 0.

x−1=0 or x+2=0

x=1 or x=−2

Choose the equation that shows the relationship of 80%, x, and 100.

Answer:

Step-by-step explanation:

so you can always put a 1 infront of a stand alone x making 1x + 6 - 6x + 10

i also like to do a little trick were you can change the subtraction sign to an addition if you make what you subtraction negitive

so we have 1x + 6 + -6x + 10

we can add 6 and 10 and 1x and -6x make an end result of

x=1

Step-by-step explanation:

You need to add the Numbers with an x together as if they were racist on each side so you'd have

4x+2 = x+5

Then to move them to either side you must do the opposite symbol of what they are so if their positive their now negative

4x-x=-2+5

then add them together

3x= 3

then divide the normal number with the number with the x

x=1

For the next problem you Multiply thr number that are in the paranthases by the number on the outside so

6-x-3 = 4(x-2)

Does anyone know this? I can't seem to figure this one out at all.

Answers

Answer:

a = 5, b = -1

Step-by-step explanation:

Simplify the left side.

Multiply both numerator and denominator by the conjugate of the denominator:

(√3 - 1)/(√3 + 1) = (√3 - 1)(√3 - 1)/(√3 - 1)(√3 + 1) =(√3² - 2√3 + 1)/(3 - 1) =(10 - 2√3)/2 = 5 - √3

Compare this to the right side to get:

5 - √3 = a + b√3a = 5, b = -1
