Answer:

I hope my drawing explains well lol... h = 16

Step-by-step explanation:

So basically first you need to find x (the one in the drawing), by doing so, you just have to use the formula,

$speed = \frac{distance}{time}$

You substitute in the speed and the time given,

$0.4 = \frac{x}{30} \\ x = 12$

Then, you use the Pythagorean theorem,

$h = \sqrt{ {20}^{2} - {12}^{2} } \\ h = 16$

What is the discrimination of the quadratic equation 8x^2-2x-1=0

ELEN [110]

$D=b^2-4ac\\D=(-2)^2-4(8)(-1)\\D=4+32\\D=36$

For another information, when D > 0, there are 2 real roots.

When D = 0, there is only one real root.

And when D < 0, there are no real roots (also known as imaginary.)

Ray uses 8 pieces of wood for each box he makes. Ray writes an equation to describe how many boxes, y, he can make with x pieces

sweet-ann [11.9K]

Answer:

$x=8y$

Step-by-step explanation:

Given: Number of pieces used to make a box = 8

x denotes total number of pieces of wood with Ray

y denotes number of boxes

To find: an equation to describe how many boxes, y, he can make with x pieces of wood.

Solution:

Total number of pieces of wood with Ray = x

As Ray uses 8 pieces of wood for each box he makes,

Number of boxes made by Ray = $\frac{x}{8}$

Also, number of boxes made by Ray = y

So,

$\frac{x}{8}=y\\ x=8y$
