<span>1.255 times the party bill. x = party bill s = sales tax t = tip C = total cost = the bill, plus the sales tax, and the tip C = x + s + t We know that both the sales tax and the tip are percentages based on the party bill. The sales tax is equal to 7.5% of the party bill. The tip is equal to 18% of the party bill. so, s = (0.075)*x and, t = (0.18)*x Then we replace the s and the t in our equation, C = x + 0.075x + 0.18x Then, we add the elements together. C = (1+0.075+0.18)x C = 1.255x</span>

Find the volume and surface area of this prism.
mina [271]

Answer:

V = 408 cm cubed

SA = 558 cm squared

Step-by-step explanation:

To find the volume of a prism, multiply the area of the base by the height. This is 1/2 times width times height times length.

V =1/2 l*w*h =1/2* 6*8*17 = 408

To find the surface area of a prism, find the area of the triangular base and the area of each rectangular side.

Area of the base is A = 1/2 * b*h = 1/2 * 6 * 8 = 24. Since there are 2 bases, the area is 48.

Area of the rectangular side is A = b*h = 17*10 = 170. Since there are three, the area is 3*170 = 510.

The surface area of the prism is 48 + 510 = 558.
