Maya cut 3 1/4 yards of fishing line from a new reel. How much is this in inches

ikadub [295]

1 yard = 3 feet:

3.25 yards x 3 feet per yard = 9.75 feet.

1 foot = 12 inches:

9.75 feet x 12 inches per foot = 117 inches.

An equilateral triangle has a height of 32. Find the length of the sides of the triangle. Round to the nearest hundredth.

telo118 [61]

Let each side=x
Use pythagorus
As height at mid of other side
Then: 32=sqrt(X^2-X^2/4)
Therefore X=36.950

Answer:

Step-by-step explanation:

Use the distance formula with the two points Q and P, then simplify and match the pattern of the answer.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d=\sqrt{(b-0)^2+(-c-(-a))^2}\\\\\boxed{d=\sqrt{b^2+(-c+a)^2}}$

The value b goes in the green box.

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 – 10x?

Marina86 [1]

we have

$6 = x^{2}- 10x$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2}- 10x+25=6+25$

$x^{2}- 10x+25=31$

Rewrite as perfect squares

$(x-5)^{2}=31$

$(x-5)=(+/-)\sqrt{31}\\ x1=5+\sqrt{31} \\ x2=5-\sqrt{31}$

therefore

the answer is

the solutions are

$x1=5+\sqrt{31} \\ x2=5-\sqrt{31}$
