Answer:

a = 5

Step-by-step explanation:

A wooden crate in the shape of a cube has a volume of 1

ladessa [460]

ANSWER

B. 8

EXPLANATION

Volume of wooden crate is

$\frac{1}{27} {ft}^{3}$

The cubic blocks have side length,

$l = \frac{1}{6} ft$

The volume of each cubic blocks is,

$v = {l}^{3}$

$= ( \frac{1}{6} )^{3} = \frac{1}{216}$

Number of blocks that can go into the crate is,

$= \frac{ \frac{1}{27} }{ \frac{1}{216} }$

$= \frac{1}{27} \times \frac{216}{1}$

$= 8 \: blocks$

Y=-|x+3| domain and range

Serjik [45]

Answer:

the domain is that x is a set of real numbers.

the range is y ≤ -3

Step-by-step explanation:

y = -|x + 3|

y is either positive or equal to zero.

Now, x is all real numbers because any value of x used will yield a valid value of y.

Thus, we can say that the domain is that x is a set of real numbers.

Now, for the range:

The minus sign in front of the absolute value indicates that the function has a maximum value.

Thus, the range is y ≤ -3
