7 ice-cream machines makes 1120 gallons of ice-cream.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, two ice cream machines make a total of 320 gallons in a certain amount of time.
Here, quantity of ice cream made by 1 machine =320/2
= 160 gallons
Now, 7 ice-cream machines makes
160×7= 1120 gallons
Therefore, 7 ice-cream machines makes 1120 gallons of ice-cream.

Sweet Treats Bakery sells gourmet cookies. If three gourmet cookies cost $7.95, then
how much will it cost to buy 10 cookies?
Answer:
$26.50
Step-by-step explanation:
7.95/3=2.65
2.65*10=26.5
Answer:
$26.50
Step-by-step explanation:
If 3 cookies are 7.95, we can do 7.95/3 to find the cost of 1 cookie.
1 cookie is 7.95/3 = 2.65.
Now, we can find the cost of 10 cookies by simply multiplying 10 to the cost of 1 cookie, which is 2.65*10 = 26.5.
10 cookies will cost $26.50.
The vertices of a feasible region are (14, 2), (0, 9), (6, 8), and (10, 3). What is the maximum value of the objective function P if P = 180x 250y?.
The maximum value of the objective function is 3080
The vertices of a feasible region are given as
(14, 2), (0, 9), (6, 8), (10, 3)
The objective function is given as:
[tex]\mathbf{P = 180x + 250y}[/tex]
Substitute the ordered pairs in the objective function
Point (14,2)
[tex]\mathbf{P = 180 \times 14 + 250 \times 2}[/tex]
[tex]\mathbf{P = 3020}[/tex]
Point (0,9)
[tex]\mathbf{P = 180 \times 0 + 250 \times 9}[/tex]
[tex]\mathbf{P = 2250}[/tex]
Point (6,8)
[tex]\mathbf{P = 180 \times 6 + 250 \times 8}[/tex]
[tex]\mathbf{P = 3080}[/tex]
Lastly, we have point (10,3)
[tex]\mathbf{P = 180 \times 10 + 250 \times 3}[/tex]
[tex]\mathbf{P = 2550}[/tex]
The maximum value of P is calculated to be 3080.
Hence, the maximum value of the objective function is 3080

what multiplication fact can you double to find 4 x 7?
Answer:
2 x 7
Step-by-step explanation:
4 x 7 = 28
Since you want doubled, we have to half to find start.
28/2 = 14
Only solid equation that equals 14 is 2 x 7
And since 4 is a double of 2, the answer checks out
The multiplication fact that can be doubled to find 4 x 7 is
2 x 7.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
4 x 7 = 28
Now,
The multiplication of 2 x 7 = 14.
If 2 x 7 is double we get,
2 x (2 x 7) = 2 x 14 = 28
Thus,
The multiplication fact is 2 x 7.
