How many 6in fence slats are required to make an 8 ft long section of privacy fences?

1 answer:

5 0

1 Foot has 12 inches.

Since the privacy fences are 8 foot long.
Multiply 8 with 12 to find the total inches required which comes out to be 96 inches.

Since fence slats are 6 inches, divide 96 by 6 to find your answer which comes out to be 16.
Thus you require 16 fence slats to make 8 foot long privacy fences.

Hope this helps!

If ( f ∘ g)(x) = x2 - 6x + 8 and g(x) = x - 3, what is f(x)?

DochEvi [55]

$\bf \begin{cases}
(f\circ g)(x)=x^2-6x+8\\\\
(f\circ g)(x)=f(~~g(x)~~)\\\\
g(x)=x-3\\
\end{cases}
\\\\\\
\textit{now, one probability is }x^2-1
\\\\\\
f(x)=x^2-1\implies f(~~g(x)~~)=(x-3)^2-1
\\\\\\
f(~~g(x)~~)=(x^2-6x+9)-1\implies f(~~g(x)~~)=x^2-6x+8$

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x becaus

Iteru [2.4K]

solve the equation ax – c = bx + d for x:

1) Group the x terms together on the left: ax - bx - c = d

2) Group the constant terms together: ax - bx = c + d

3) factor out x: x(a - b) = c + d

4) Divide both sides of the equation by (a - b) to obtain a formula for x:
c+d
 x(a - b) = c + d => x = ---------
a-b

This shows that the given equation CAN be solved for x, but there is a restriction: a must NOT equal b, because if a-b = 0, we'd have division by zero (which is not defined).

Where is Victoria's solution? Please share it if you want to discuss this problem further. Thank you.

Look at the question

ziro4ka [17]

Answer:

Step-by-step explanation:

The better buy is the one where you get more area of pizza per dollar (area/price).

Since the problem gives diameter, we assume the pizzas are circle-shaped.

Circle Area = pi x (radius)², and radius r = 1/2 of diameter d.

*************************************************************************************

Pizza 1: d = 8 and price is $10

r = 1/2 x d = 4

Area of Pizza 1 = πr² = π(4)² = 16π

*** area/price for Pizza 1 = 16π/$10 = 1.6π area per dollar

**********************************************************************************

Pizza 2: d = 14 and price is $16

r = 1/2 x d = 7

Area of Pizza 2 = πr² = π(7)² = 49π

*** area/price for Pizza 2 = 49π/16 = 3.0625π area per dollar

***********************************************************************************

Pizza 2 is the better buy, with more pizza per dollar.
