9 pounds of ground beef cost $40.32. What is the price per ounce?
The price per ounce of ground beef, when 9 pounds cost $40.32, is $0.28.
Calculating Price per Ounce of Ground Beef
To calculate the price per ounce for ground beef when given the price for 9 pounds, we will first need to know how many ounces are in 9 pounds. Since there are 16 ounces in 1 pound, 9 pounds is equivalent to 144 ounces (9 pounds × 16 ounces/pound).
Next, we divide the total cost of the 9 pounds of ground beef by the total number of ounces to find the price per ounce. The total cost given is $40.32.
Price per ounce = Total cost \/ Total number of ounces
Price per ounce = $40.32 \/ 144 ounces
Price per ounce = $0.28
Therefore, the price per ounce of ground beef is $0.28.
If the area A of a triangle is 45 m2 (square meters) and the altitude h is 15 m, what's the base b?
Answer:
The base b is 6m
Step-by-step explanation:
The area A of a triangle with base b and height h is given by the formula;
[tex]A=\frac{1}{2}*b*h[/tex]
The area of the triangle is given as 45 while the height h is 15. We substitute these known values into the formula above and solve for the unknown base;
[tex]45=\frac{1}{2}*b*15\\\\90=15*b[/tex]
We finally divide both sides by 15 to solve for b;
b = 90/15 = 6
Therefore, the base of the triangle is 6 m
Answer:
[tex]b = 6\ m[/tex]
Step-by-step explanation:
The area of a triangle is
[tex]A = 0.5b * h[/tex]
Where b is the base of the triangle and ha is the height.
In this case we have a triangle with area
[tex]A = 45\ m ^ 2[/tex]
and with height:
[tex]h = 15\ m[/tex]
So the base of the triangle is:
[tex]45 = 0.5b (15)\\\\b=\frac{45}{15*0.5}\\\\b=6\ m[/tex]
Finally the base of the triangle is b = 6 meters

If f(x)=2x and g(x)= 1/x, what is the domain of (f*g) (x)
Answer:
The domain of (f*g) (x) is the set of all real numbers; ( -∞, ∞)
Step-by-step explanation:
(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;
f(x)=2x
g(x)= 1/x
(f*g) (x) = f(x) * g(x)
(f*g) (x) = 2x * 1/x = 2
This is a horizontal line defined everywhere on the real line. The domain of (f*g) (x) is thus ( -∞, ∞)
Answer:
All real numbers
Step-by-step explanation:
Given : [tex]f(x)=2x[/tex]
[tex]g(x)= \frac{1}{x}[/tex]
To Find : the domain of (f*g) (x)
[tex]f(x)=2x[/tex]
[tex]g(x)= \frac{1}{x}[/tex]
[tex](f\cdot g)(x)=2x \times \frac{1}{x}[/tex]
[tex](f\cdot g)(x)=2[/tex]
Since the value of [tex](f\cdot g)(x)=2[/tex]
So, the domain of the function is [tex](f\cdot g)(x)[/tex] is all real numbers .

a Potter uses 3/5 of a pound of clay to make a bowl how many bowls could the Potter make from 10 lb of clay
Answer:
16
Step-by-step explanation:
Let's say x is the number of bowls. If each bowl needs 3/5 pound of clay, then the total clay needed is 3/5 * x. We know the total amount is 10 pounds. Therefore:
10 = 3/5 x
Divide:
x = 10 / (3/5)
To divide by a fraction, we need to multiply by the reciprocal:
x = 10 * (5/3)
x = 50/3
x = 16 ⅔
We can't have part of a bowl, so we must round down. The potter can make 16 bowls.

paige and her family went to the movies. They bought 4 tickets and paid $12 for popcorn. They spent $40. How much did each ticket cost?
____________________________________________________
Answer:
7 dollars
____________________________________________________
Step-by-step explanation:
To make solving this equation easier, lets turn the the information we got in the question into an actual equation.
Key information:
4 tickets
$12 popcorn
Spent a TOTAL of $40.
With the information above, we can use it to make an equation.
We would use the equation: y = mx + b
Since our "y" value would represent our total value, our total value is 40, so we would plug 40 into y.
Your equation should look like this:
40 = mx + b
Our "b" value represents our start value, and our start value would be 12 because we started with one $12 popcorn.
Your equation should look like this:
40 = mx + 12
Our "m" value would represent how many tickets we bought, so we would plug in 4 in m.
Our equation would be:
40 = 4x + 12
Now we can solve the equation:
We would move the 12 over to the left side of the equal sign by subtracting, then we would divide by 4.
[tex]40=4x+12\\\\28=4x\\\\7=x[/tex]
We should get ther answer of 7, that means that each ticket cost $7 dollars.
7 dollars should be your FINAL answer.
____________________________________________________
Answer:
One ticket = $7
Step-by-step explanation:
Forming the equation,
→ 4x + 12 = 40
Now the value of x will be,
→ 4x + 12 = 40
→ 4x = 40 - 12
→ x = 28/4
→ [ x = 7 ]
Hence, the value of x is 7.

Step-by-step explanation:
Final answer:
The product of the binomials (x + 3)(x - 8) is simplified using the FOIL method to get x² - 5x - 24. We multiply each term in the first parenthesis by each term in the second and combine like terms.
Explanation:
To multiply and simplify the expression (x + 3)(x - 8), we will use the FOIL method (First, Outer, Inner, Last). This method involves multiplying each term in the first parenthesis by each term in the second parenthesis.
First: x times x = x²
Outer: x times -8 = -8x
Inner: 3 times x = +3x
Last: 3 times -8 = -24
Next, combine like terms (-8x and +3x):
x² - 8x + 3x - 24 = x² - 5x - 24
The simplified form of the given expression is x² - 5x - 24, which corresponds to option C).
what is the other binomial?
Answer:
11x² -3x
Step-by-step explanation:
We have the product of a sum, of two binomials and one of the initial binomials but we'd like to know the other one.
It's very much like A + B = C, and we have both B and C, but looking to find A.
What would you do in the ABC scenario?
You'd isolate A by transforming the equation to: A = C - B
In this case, C = 12x² - 5x and B = x² - 2x...
A = (12x² - 5x) - (x² - 2x) = 12x² - 5x - x² + 2x
A = 11x² -3x
