Maranda praticed a total of 52 hours in 4 weeks to prepare for a piano recital. If she practiced the same number of hours each w

RUDIKE [14]

The number of practice hours per week for Maranda's piano recital is 13 hours

Overall practice hours = 52 hours

Number of weeks of practice = 4 weeks

Since, the number of practice hours per week is the same ;

Number of hours practiced each week can be obtained by dividing the overall practice hours by the number of weeks of practice.

Number of practice hours per week = Overall practice hours ÷ Number of weeks of practice

Number of practice hours = (52 ÷ 4) = 13 hours

Therefore, Marana practiced for 13 hours each week.

Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit. Select all that apply.

sergij07 [2.7K]

We can use using graphing technology to solve the system of equations here.

So draw sketch of graphs $y = 8^{(x-9)}$ and $y = log (3x) +2$ on graphing calculator. you will get sketch as shown

Take pointer to point of intersection as shown. It displays (x,y) coordinate of points of intersection as (9.597, 3.459) as show in figure.

Now round off these values to nearest tenth thats one digit after decimal dot.

so to round 9.597 to one decimal place we will see 2nd decimal digit(next to place where you have to round off) which is 9 here and as 9 is greater than 5 so we will increase 1st decimal place digit by 1, so round to one decimal place will be 9.6.

Similarly to round off 3.459 to one decimal place we will see 2nd decimal digit which is 5. Again as its equals 5 we will increase the 1st decimal digit by 1 for round off. So final round off to one decimal place will be 3.5

So final answer for solution set will be choice C (9.6, 3.5)
