Every time Luisa bakes a batch of brownies, she uses 12 cup of chocolate. If she has 32 cup(s) of chocolate remaining, how many batches of brownies can Luisa make? Input your answer as a whole number.
This question was not properly written
Complete Question
Every time Luisa bakes a batch of brownies she uses 1/2 cup of chocolate if she has 3/2 cups of chocolate remaining how many batches of brownies can Luisa make
Answer:
3 batches of brownies from 3/2 cups of chocolate left.
Step-by-step explanation:
From the question, we know that:
1/2 cups of chocolate = 1 batch of brownies
3/2 cups of chocolate = x
Cross Multiply
1/2 × x = 3/2
x = 3/2/1/2
x = 3/2 × 2/1
x = 3 batches.
Approximately as a whole number , he can make 3 batches of brownies from 3/2 cups of chocolate left
Graph 8x−4y=16. From Big Ideas Math
Solve for y.
8x−4y=16
-4y = -8x + 16
y = (-8x + 16)/-4
y = (-8x)/-4 + (16/-4)
y = 2x - 4
We only need two points to graph linear equations.
Now let x be 0 and solve for y.
y = 2(0) - 4
y = -4
This leads to the point (0, -4).
We need another point.
Let y = 0 and solve for x.
0 = 2x - 4
4 = 2x
4/2 = x
2 = x
This leads to the point (2,0).
Plot these two points on the xy-plane and connect the points with a straight line.
I'll let you do that.
Understand?

A container holds 4 gallons of lemonade. A large lemonade contains 16 ounces. How many large lemonades could the restaurant cell before they ran out of lemonade?
Given:
A container holds 4 gallons of lemonade.
A large lemonade contains 16 ounces.
To find:
The number of large lemonades that the restaurant can cell before they ran out of lemonade.
Solution:
We know that,
1 gallon = 128 ounces
4 gallon = 512 ounces
So, a container holds 512 ounces of lemonade.
A large lemonade contains 16 ounces. So,
[tex]\text{Number of large lemonades}=\dfrac{\text{Total lemonade in container}}{\text{Lemonade in a large container}}[/tex]
[tex]\text{Number of large lemonades}=\dfrac{512}{16}[/tex]
[tex]\text{Number of large lemonades}=32[/tex]
Therefore, the required number of lemonades is 32.

Explanation:
The rule for reflecting over y = x is [tex](x,y) \to (y,x)[/tex]
The x and y coordinates swap places.
Point E' is located at (6, -2) so that means point E must be located at (-2, 6)

Step-by-step explanation:
A children clothing manufacturer has 500 yards of material to make shirts and skirts. A shirt requires 0.5 yards of fabric, and a skirt requires 1 yard of fabric. It takes 1 hour to make a shirt and 1.5 hours to make a skirt. The manufacture has 800 hours available to make shirts and skirts.
Answer:
C) x ≥ 0 and y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
Step-by-step explanation:
A children clothing manufacturer has 500 yards of material to make shirts and skirts. A shirt requires 0.5 yards of fabric, and a skirt requires 1 yard of fabric. It takes 1 hour to make a shirt and 1.5 hours to make a skirt. The manufacture has 800 hours available to make shirts and skirts.
Which system of inequalities represent the constraints for this situation? Let x = number of shirts, and let y = number of skirts.
A) x ≤ 0 and y ≤ 0
0.5x + y ≤ 800
x + 1.5y ≤ 500
B) x ≤ 0 and y ≤ 0
0.5x + y ≥ 800
x + 1.5y ≥ 500
C) x ≥ 0 and y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
D) x ≥ 0 and y ≥ 0
0.5x + y ≥ 500
x + 1.5y ≥ 800
number of shirts,x and number of skirts,y must be greater than 0 since it can not be a negative value
x ≥ 0 ; y ≥ 0
Inequality for number of yards
x = 0.5 yards ; y = 1 yard
Total yards = 500
The inequality is
0.5x + y ≤ 500
Inequality for hours of production
x = 1 hour ; y = 1.5 hours
Total available hours for production = 800
The inequality is
x + 1.5y ≤ 800
Therefore, the system of inequalities which represent the constraints for this situation is
x ≥ 0 ; y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
x ≥ 0 and y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
When graphed the system shows that the manufacturer should make 200 shirts and 400 skirts for a maximum profit.
Mason can plant 12 bushes in 60 minutes. How many can he plant in 3 hours?
Well first-
Mason planted 12 bushes in one hour, so basically all you have to do is multiply the amount of bushes planted in a hour (12) by the hours (3) so-
12 x 3 = 36 plants for 3 hours

Sally found the deal of the century when buying a TV. • The store advertised the TV for 1/3 off. • At the register she handed the cashier a coupon for an additional 1/4 off. If the TV originally cost $320 how much did she pay for it?
Answer:
$160
Step-by-step explanation:
These discounts would be added one after the other. Therefore, we would first apply the first discount of 1/3 to the original price. Since it is a discount it means that from the original price we would pay 2/3. We do this by multiplying this fraction by the original price like so...
$320 * (2/3) = $213.33
Now we add the second discount of 1/4. Again, since it is a discount it means that we would be paying 3/4 of the current price.
$213.33 * 3/4 = $160
Finally, we can see that Sally would have ended up paying $160 for the TV.

Answer:
(-1, 2)
Step-by-step explanation:
The salaries of a random sample of a company's employees are summarized in the frequency
distribution below. Approximate the sample mean.
Salary (5) Employees
3.001-10,000 14
10.001-15,000 16
15.001-20,000 14
20.001-25.000
17
25.001-30.000
19
The required approximate sample mean salary is $17750.725.
How to find the sample mean?
To approximate the sample mean, we first need to find the midpoint of each salary range and then multiply it by the number of employees in that range to get the total salary for that range. Then we can sum the total salaries and divide by the total number of employees to get the sample mean.
The midpoint of each salary range can be found by taking the average of the lower and upper bounds of the range. For example, the midpoint of the first range (3.001-10,000) is (3.001 + 10,000) / 2 = 5001.5005.
Using this approach, we can construct the following table:
Salary (5) Employees Midpoint Total Salary
3.001-10,000 14 5001.5005 70021.007
10.001-15,000 16 12500.5000 200008.000
15.001-20,000 14 17500.5000 245007.000
20.001-25.000 17 22500.5000 382511.500
25.001-30.000 19 27500.5000 522510.500
To find the sample mean, we add up the total salaries and divide by the total number of employees:
[tex]$\bar{x} = \frac{\sum_{i=1}^n x_i}{n} = \frac{70021.007 + 200008.000 + 245007.000 + 382511.500 + 522510.500}{14 + 16 + 14 + 17 + 19} \approx 17750.725$[/tex]
Therefore, the approximate sample mean salary is $17750.725
