PLEASE HELP NOW Ava spends about 45 minutes studying each day. She also practices the piano for an average of 20 minutes per day, and she practices soccer 1.5 hours three times a week. If Ava decides to reduce the time she does each activity by 16, find the total number of hours she spends studying and practicing in a year with a reasonable level of accuracy.

1. Ava spends 45min per day studying

reduce this amount be 16min we have=45-16=29min

in a year she will spend 365*29= 10585min

2. She also practices the piano for an average of 20 minutes per day

reduce this amount be 16min we have=20-16=4min

in a year she will spend 365*14= 5110min

3. She practices soccer 1.5 hours three times a week.

in minutes 1.5hours is 90min three times a week

in a day 90*3/7= 270/7=38.57

reduce this amount be 16min we have=38.57-16=22.57min

in a year she will spend 365*22.57= 8238.05min

in total for the year she spends studying and practicing

=10585+ 5110+8238.05

=23933.05min to hours =23933.05/60

=398.88hours

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

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!
