Charlie's Computer Company charges $0.65 per pound to ship computers. Part A: Write an equation to determine the total cost, c,

Harlamova29_29 [7]

Step-by-step explanation:

One pound = $0.65

Total cost = c

Number of pounds to ship = p

Part a:

c = 0.65p

When p = 2

c= 0.65(2)

c = $1.30

Part b:

One pound = $0.65 - $0.05 = $0.60

c= 0.6p

Answer: (a) $1.30 (b) c= 0.6p

upon his death, mr. moneybags left 1/2 of his estate to his wife 1/8 to each of his two children, 1/10 to each of his grandchild

stiks02 [169]

The picture looks confusing.
You divide 10000 by 1/10 then times that by 2 which equals 200,000 then divide that by 1/8 which is 160,000 then by 1/2 and you get 3,200,000

What is the roots of f(x)=-x^2-6x-14

Nutka1998 [239]

Answer:

$x=-3\pm i \sqrt{5}$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Algebra II

Imaginary roots: √-1 = i

Step-by-step explanation:

Step 1: Define function

f(x) = -x² - 6x - 14

Step 2: Set up

Set equation equal to 0: -x² - 6x - 14 = 0
Factor out -1: -(x² + 6x + 14) = 0
Divide both sides by -1: x² + 6x + 14 = 0

Step 3: Define variables

a = 1

b = 6

c = 14

Step 4: Find roots

Substitute: $x=\frac{-6\pm\sqrt{6^2-4(1)(14)} }{2(1)}$
Exponents: $x=\frac{-6\pm\sqrt{36-4(1)(14)} }{2(1)}$
Multiply: $x=\frac{-6\pm\sqrt{36-56} }{2}$
Subtract: $x=\frac{-6\pm\sqrt{-20} }{2}$
Factor: $x=\frac{-6\pm\sqrt{-1} \sqrt{20} }{2}$
Simplify: $x=\frac{-6\pm2i \sqrt{5} }{2}$
Factor: $x=\frac{2(-3\pm i \sqrt{5} )}{2}$
Divide: $x=-3\pm i \sqrt{5}$

Simplify. 3 ft 23 in.

sleet_krkn [62]

Answer:

4 ft 11 inches

Step-by-step explanation:

Remember that 12 inches is 1 foot, so 24 inches is 2 feet. That means, 23 inches is 1 foot 11 inches. 11/12 is one inch gone from a foot, so 23/24 much be one inch gone from 2 feet.

Since you already have 3 feet, adding the 1 foot and 11 inches leaves you with 4 ft 11 inches as a result.
