The percentage profit is 140%

What is percentage?

Percentage can be described as the expression of a number in hundredth.

The formula for calculating percentage profit is

profit/cost price × 100

cost price=  $50
selling price= $15
number of mats produced= 8

selling price of the mat= 15 × 8
= 120

Profit= selling price-cost price

= 120-50
$70

Therefore the percentage profit can be calculated as follows

= 70/50 × 100
= 1.4 ×100
= 140

Thus, the percentage profit is 140%

Help with this question
Sholpan [36]

With some simplification,

cos⁻¹(x) - 5 cos⁻¹(x) - π/3 = 2π/3

becomes

-4 cos⁻¹(x) = π

or

cos⁻¹(x) = -π/4

However, the inverse cosine function has a range of 0 ≤ cos⁻¹(x) ≤ π, so there are no solutions to this equation.

deff fn [24]

Answer:

[see below]

Step-by-step explanation:

Volume of a triangular prism is: V=\frac{1}{2}bhl

We are given the base of 5, the length of 12, and the height of 8. All measurements are in meters.

V=\frac{1}{2}(5*12*8)\\\\V=\frac{1}{2}(480)\\\\V=240

The volume of the prism should be 240 square meters.
