Answer 1

Answer: If you would like to find the dimensions of the box in inches, you can calculate this using the following steps:

width ... x inches
length ... (x + 5) inches
height ... (3 * x - 1) inches

volume ... 7.6 ft³
1 foot = 12 inches
7.6 ft³ = 13132.80 in³

volume = width * length * height
13133 = x * (x + 5) * (3 * x - 1)
13133 = (x^2 + 5 * x) * (3 * x - 1)
13133 = 3 * x^3 - x^2 + 15 * x^2 - 5 * x
13133 = 3 * x^3 + 14 * x^2 - 5 * x
0 = 3 * x^3 + 14 * x^2 - 5 * x - 13133
1. x ≈ 14.972 ≈ 15
2.x ≈ -9.820 + 13.998 * i
3. x ≈ -9.820 - 13.998 * i

width ... x inches = 15 inches
length ... (x + 5) inches = 15 + 5 = 20 inches
height ... (3 * x - 1) inches = 3 * 15 - 1 = 45 - 1 = 44 inches

The dimensions of the box are 15 inches, 20 inches and 44 inches.

Santino bought a book for $23.54. The price of the book was $22. What was the sales-tax rate?

Answers

We first find value of tax in dollars.

The difference between the two prices is: 23. 54 - 22 = 1.54

Therefore the sales tax in dollars is 1.54

The tax % will be (amount of tax / original cost price ) × 100

(1.54 / 22) × 100 → (0.07) × 100 = 7

So the tax rate is 7%

We can double check the answer.

7 % of 22 → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54
