XZ=n, WZ=2x-5, and the perimeter of ΔXWZ is 20. What is the value of n?

Sergio039 [100]

Answer:

Step-by-step explanation:

Since it's an isosceles triangle, WX=WZ= 2n-5

Perimeter = n + (2n-5) + (2n-5)

= 5n - 10

The Perimeter is given to be 20

5n - 10 = 20

5n = 30

n = 6

Find the y-intercept from the line passing through (1, 3) and having slope m=2.

Troyanec [42]

Answer:

The y intercept is 1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation and solve for y

3 = 2(1)+b

3 =2+b

1 = b

The y intercept is 1

Peter is making an "X marks the spot" flag for a treasure hunt. The flag is made of a square white flag with sides of 12 centime

zheka24 [161]

Answer:

34 cm

Step-by-step explanation:

The actual question is How many inches of ribbon Peter will need to make the "X".

Using the Pythagorean theorem, the length of the diagonal of a square with 12 cm sides is:

$d^2=12^2+12^2\\d=\sqrt{288}\\ d=16.97\ cm$

Since the "X" requires two diagonals, the length of ribbon required is:

$L=2*16.97\\L=34\ cm$

The length required, rounded to the nearest centimeter, is 34 cm.
