A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs after selling 10 tickets, they were still a net loss of $800 (due to the product cost). They sold each ticket for $70 let y represent the net profit (in dollars) when they have sold x tickets

Answers

Answer:

y = 70x - 1500

Step-by-step explanation:

Price per ticket = 70

Using the relation :

y = mx + c

x = number of tickets sold

When x = 10 ; y = - 800

Hence,

-800 = 70(10) + c

-800 = 700 + c

-800 - 700 = c

Hence, c = - 1500

The equation for the net profit in dollars is :

y = 70x - 1500

Use polynomial identities to factor 64 + 27a^3

Answers

Answer:

(3a+4)(9a^2-12a+16)

Step-by-step explanation:

It's a perfect square :)

The factors of the given polynomial are (4+3a)(9a²-12a+16)

What is polynomial?

A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using mathematical operations.

Given that, a polynomial, 64+27a³

Using identity : a³+b³ = (a+b)(a²-ab+b²)

We get,

= (4+3b)(4²-4x3a+(3a)²)

= (4+3a)(16-12a+9a²)

Hence, the factors of the given polynomial are (4+3a)(9a²-12a+16)

A thermometer manufacturer compares the reading on one of its thermometers to a thermometer that they know is accurate. The accurate thermometer reads 25 degrees Celsius. Their thermometer reads 30 degrees Celsius. What is the percent error in their thermometer's reading?
A.2%
B.20%
C.83%
D.16%

Answers

Answer:

B. 20%

Step-by-step explanation:

Percentage Error = (Actual Value - Expected Value) / Expected Value * 100

Actual Value = 30

Expected Value = 25

Percentage Error = (30 - 25) / 25 * 100

Percentage Error = (5) / 25 * 100

Percentage Error = 0.2 * 100

Percentage Error = 20
