find each unit price and decide which is a better buy (cheaper) Treated lumber $3.79 for an 8 foot board. or $6.18 for a 12 foot board?
Answer:
$3.79 for an 8 foot board
Step-by-step explanation:
The way to find the answer is calculating the price per foot.
Part 1
$3.79 for an 8 foot board.
one foot would cost:
$3.79 ÷ 8 = 0.47375
Part 2
$6.18 for a 12 foot board?
Price of one foot would be:
$6.18 ÷ 12 = 0.515
$0.47375 is less than $0.515. So, the cheaper treated lumber is the one costing $3.79 for an 8 foot board.
The equation of a line is given by 4x-3y=12.How do you solve for x
Simplifying
4x + -3y = 12
Solving
4x + -3y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
4x + -3y + 3y = 12 + 3y
Combine like terms: -3y + 3y = 0
4x + 0 = 12 + 3y
4x = 12 + 3y
Divide each side by '4'.
x = 3 + 0.75y
Simplifying
x = 3 + 0.75y

convert 84 inches to yards
Answer:
The answer is 2.333 yards
Step-by-step explanation:
In every one yard there's thirty-six inches.
84/36= 2.333
Hope this helps :)
To convert 84 inches to yards, first convert inches to feet by dividing by 12, resulting in 7 feet. Then, convert feet to yards by dividing by 3, resulting in approximately 2.33 yards.
To convert 84 inches to yards, we need to use the relationships between inches, feet, and yards.
Start by converting inches to feet, and then convert feet to yards.
1. Convert inches to feet:
There are 12 inches in a foot, so divide the number of inches by 12.
84 ÷ 12
= 7 feet
2. Convert feet to yards:
There are 3 feet in a yard, so divide the number of feet by 3.
7 ÷ 3
= 2.33 yards
Thus, 84 inches is equal to approximately 2.33 yards.

If b2 + 2b − 24 = 0, and b < 0, what is the value of b?
A) −6
B) −4
C) −2
D) 0
The value of b is -6.
Explanation:To find the value of b, we need to solve the quadratic equation b2 + 2b - 24 = 0.
Since b < 0, we can eliminate the positive solution.
We can factor the equation by finding two numbers whose product is -24 and sum is 2.
The numbers are -4 and 6.
So, the factored form of the equation is (b - 4)(b + 6) = 0.
Setting each factor equal to zero, we find that b = -6 or b = 4.
Since b < 0, the value of b is -6.

#SPJ12
Final answer:
Using the quadratic formula, we find that b = -6 (option A), considering the requirement that b < 0 for the equation b² + 2b - 24 = 0.
Explanation:
To find the value of b given the quadratic equation b² + 2b − 24 = 0 and knowing that b is less than zero, we can use the quadratic formula:
The quadratic formula is −b ± √(b² − 4ac /2a), where a, b, and c are coefficients from the quadratic equation in the form ax2 + bx + c = 0.
In this case, a = 1, b = 2, and c = −24. Applying these values to the quadratic formula, we have:
−(2) ± √((2)² − 4(1)(−24) /2(1))
The discriminant part of the formula, b² − 4ac, equals (2)² − 4(1)(−24) = 4 + 96 = 100. Therefore, the square root of the discriminant is 10.
Simplifying further, we have:
(−2 ± 10) / 2 = −6 or +8
Since b < 0, we disregard the positive solution and consider b = −6, which is option A.

In the right triangle ABX
[tex]AB=90\ ft[/tex]
[tex]BX=(3/4)90=67.5\ ft[/tex]
XA --------> is the distance the player throws the ball (hypotenuse of the right triangle)
Applying the Pythagoras Theorem
[tex]XA^{2}=AB^{2}+BX^{2}[/tex]
substitute the values
[tex]XA^{2}=90^{2}+67.5^{2}[/tex]
[tex]XA^{2}=12,656.25[/tex]
[tex]XA=112.5\ ft[/tex]
The distance player throws the call was calculated using Pythagoras theorem and it is 112.5 feet.
It is given that
Side of the square = 90 feet
Distance of point x from the second base = 3/4 * 90 = 67.5
The distance the player throws the call let us say D will be the shortest distance between x and 1st base.
Distance D can be calculated by Pythagoras theorem
What is Pythagoras theorem?
In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the perpendicular and the base.
[tex]D = \sqrt{90^{2} +67.5^{2} }[/tex]
[tex]D = \sqrt{8100+4556.25} \\\\D = \sqrt{12656.25\\}\\[/tex]

Which of the following is the solution to the following system of inequalities? Let the green region represent the solution set. X+2y<=4 3x-y>2
Answer:
See picture attached.
Step-by-step explanation:
To find the solution, graph each equation using the y = mx + b form.
Start by converting to this form.
x + 2y < 4 becomes y < -1/2x +2
3x - y > 2 becomes y < 3x - 2
Then mark each y-intercept. These points are (0,2) and (0,-2).
Using the slope mark the next points at (-1,4) and (1, -1) respectively.
Connect using dash lines since this is not equal to in either inequality.
Test a point no on either line like (-1,-1).
If the inequality holds true, shade the area.
Where the areas overlap is the solution. See picture.
Inequalities are used to represent unequal expressions.
The solution to the inequality is [tex]x \le \frac 87[/tex] and [tex]y < \frac{10}7[/tex]
The inequalities are given as:
[tex]x + 2y \le 4[/tex]

[tex]3x -y = 2[/tex]
Make y the subject in [tex]3x -y = 2[/tex]
[tex]y = 3x - 2[/tex]
Substitute [tex]y = 3x - 2[/tex] in [tex]x + 2y \le 4[/tex]
[tex]x + 2(3x - 2) \le 4[/tex]
Open brackets
[tex]x + 6x - 4 \le 4[/tex]
[tex]7x - 4 \le 4[/tex]
Collect like terms
[tex]7x \le 4+4[/tex]
[tex]7x \le 8[/tex]
Divide both sides by 7

the table shows how much jake charged for the last 4 orders of pup cakes. what is the constant of proportionality in cost per pup cake?
Answer:
$2.50
Step-by-step explanation:
Let's take a look at the 4 orders and check the price per pup cake in each order:
Order 1: $5 for 2 cakes, so $2.50 per cake.
Order 2: $7.50 for 3 cakes, so $2.50 per cake.
Order 3: $12.50 for 5 cakes, so $2.50 per cake.
Order 4: $20.00 for 8 cakes, so $2.50 per cake.
Jake has a very consistent pricing of his cakes... they're always $2.50 each.
That price is the relation between the price asked and the number of cakes sold, that's the constant of proportionality in this case.
Answer:
Option 3rd is correct
$2.5 is the constant of proportionality in cost per pup cake
Step-by-step explanation:
The direct proportionality states that:
[tex]y \propto x[/tex]
then the equation is in the form of :
[tex]y = kx[/tex] ....[1]
where, k is the constant of proportionality.
As per the statement:
The table shows how much Jake charged for the last 4 orders of pup cakes.
Let y represents the cost and x represents the pup-cakes
Consider any values of x and y from the given tables.
x = 3 and y = $7.5
To find constant of proportionality in cost per pup cake.
Substitute these in [1] we have;
[tex]7.5 = 3k[/tex]
Divide both sides by 3 we have;
2.5 = k
or
k = 2.5
Therefore, $2.5 is the constant of proportionality in cost per pup cake
