On a typical day flight at a local airport arrive at a rate of 10 every 15 minutes at this rate how many flights would you expect to arrive in one hour

60/15 = 4

10 x 4 = 40

so 40 flights

Step-by-step explanation:

There are 60 minutes every hour. That means there are 4 intervals of 15 minutes in one hour (60/15 equals 4). Each interval brings in 10 flight, so if we multiply the 10 flights by the 4 intervals, we end up with 40, which is our answer

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!

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
