A bicycle has a listed price of $544.98 before tax. If the sales tax rate is 9.75%, find the total cost of the bicycle with sale
CaHeK987 [17]

Answer:

$598.12.

Step-by-step explanation:

First you need to make the percent into a decimal and multiply it by the price without tax: 0.0975 · 544.98, which equals 53.136 when rounded to the nearest thousandth. This means that 53.136 is 9.75% of 544.98. Then you just need to add 53.136, or 53.14 when rounded, to 544.98. This gives you $598.12.

The diagonals of a kite are in the ratio 3 : 2. The area of the kite is 27cm(squared). find the length of both diagonals.
alina1380 [7]
P= 27 \ cm^2 \\ \\P=\frac{1}{2} e * f \\ \\ f =3x , \ e = 2x \\ \\27=\frac{1}{2}*2*3x \\ \\27=3x/:3

x=3 \\ \\ f =3x =3 *3= 9 \ cm \\ \\ \ e = 2x = 2*3 = 6cm

9. Triangle Construction pays Square Insurance $5,980
xxTIMURxx [149]

The triangle pay $32 more for that day than it paid per day during the first period of time.

Step-by-step explanation:

The given is,

              Triangle Construction pays Square Insurance $5,980

               To insure a construction site for 92 days

               To extend the  insurance beyond the 92 days costs $97 per day

               Triangle extends the insurance by 1 day

Step:1

              Insurance per day from the 92 days period,

                                                                           = \frac{Total insuratio for 92 days}{Period}

               Where, Total insurance for 92 days = $ 5,980

                                                               Period = 92 days

               From the values, equation becomes,

                                                                            =\frac{5980}{92}

                                                                           = $ 65 per day

Step:2

              Insurance per day after the 92 days,

                                                                           = $ 97

               Amount Pay for that day than it paid per day during the first period of time,

                                                                            =(97-65)

                                                                           = $32

Result:

             The triangle pay $32 more for that day than it paid per day during the first period of time, if  the Triangle Construction pays Square Insurance $5,980 to insure a construction site for 92 days and to extend the  insurance beyond the 92 days costs $97 per day.

What are the solutions of the equation x6 – 9x3 + 8 = 0? Use u substitution to solve.
Natalka [10]
X6 – 9x3 + 8 = 0
let u = x^3
u^2 - 9u + 8 = 0 
(u-8)(u-1) = 0
u = 1,8
back substitute 
1 = x^3
8 = x^3
