Achef can bake 15 pies in one hour. what is the rate in pies per minute? (a) 0.25 pies/min (b) 0.625 pies/min (c) 4 pies/min (d) 1.6 pies/min

The chef can bake (a) 0.25 pies/min.

Step-by-step explanation:

1 hour = 60 minutes

1 hour = 15 pies

15=60m

15/60 = 60/60 m

0.25 = m

5

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
