This refers to the actual value. Therefore you can plug it into the calculator:
Sin of 30= 1/2
Cos30=√3/2
6x^2+3x+9. (combine the two X^2 then the other two don’t have pairs)
The sales tax is the additional cost with a value of a fraction of the gross cost. Let's compute first the gross cost:
Gross cost = 3($1.59) + 2($3.25) = $11.27
The sales tax is, therefore, 7.25% of $11.27.
Sales Tax cost = $11.27(0.0725) = $0.817
The total purchase is equal to the gross cost and the sales tax cost.
Total Purchase Cost = $11.27 + $0.817 = $12.09

Find attached to this question the diagram of the cube.
Reference for the attached image: This diagram was obtained from Education Quality and Accountability Office (EQAO) PDF
Answer:
128cm³
Step-by-step explanation:
The diagram of the box shows it has a side length of 9.2cm
Volume of a cube =( Length)³
Volume of a cube =( 9.2cm)³
= 778.688cm³
We are told in the question that the decoration packed in the cube has a volume of 651 cm³.
The amount of empty space remaining in the box is calculated as:
778.688cm³ - 651cm³
= 127.688cm³
Approximately to the nearest whole number = 128cm³
