Jacob has 27.5 pounds of coffee beans to grandpa's got too much coffee is Jacob is able to fill container with 2.5 lb of coffee each time he grinds the beans, how many times do we have to fill container to grind all the beans?

Step-by-step explanation:

The answer is 30  times to fill the container to grind beans.

11 times

Step-by-step explanation:

27.5 divided by 2.5 is 11

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
