Answer:
7 ice cream machines can make 1,120 gallons of ice cream
Step-by-step explanation:
Divide 320 by 2
multiply 160 by 7
you should get 1,120
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.

A queen-sized mattress is 20 inches longer than it is wide. A king-sized mattress is
16 inches wider that the queen-sized mattress but has the same length. The area
of the king sided mattress is 1,280 square inches more than that of the
queen-sized mattress. Determine the dimensions (length and width) of both the
king-sized and queen sized mattresses.
Answer:
queen's width = 60 in
queen's length = 80 in
king's width = 76 in
king's length = 80 in
Step-by-step explanation:
-queen's wide = ???
-same length = queen's wide + 20
king size:
-king's wide = queen's wide + 16
-same length = queen's wide + 20
queen's area = x
king's area = x + 1280
area = width * length
let's call queen's width and king's width "qw" and "kw" respectively
let's call queen's length and king's length "ql" and "kl" respectively
Q area:
qw * (qw + 20)
qw² + 20qw = x
K area:
(qw + 16) * (qw + 20) = x + 1280
qw² + 36qw + 320 = qw² + 20qw + 1280
qw² - qw² + 36qw - 20qw = 1280 - 320
16qw = 960
qw = 960 / 16
qw = 60
ql = 60 + 20
ql = 80
kw = 60 + 16
kw = 76
kl = ql
kl = 80

Step-by-step explanation:
Molly drew a map of her town. She graphed the point L(−1.75, −3) for the library. The ice cream shop is located at L′, a reflection of L across the x-axis. The fire station is located at L′′, a reflection of L′ across the y-axis. Identify the ordered pair that describes the location of the fire station. Express your answer using decimal notation.
(__,__)
Answer:
(1.75, 3)
Step-by-step explanation:
Let's find L' first: We are reflecting L over the x axis, it means it stays on the same vertical (x=-1.75) and it's y changes sign, going to (-1,75,3).
This new point gets reflected again, over the y-axis. The horizontal coordinate (y=3) remains the same, and the x coordinate changes sign, going to it's final destination (1,75, 3)
For the equation y = -x +5, find y when x = -3
Answer:
y= 8
Step-by-step explanation:
y= -x +5
To find the value of y when x= -3, substitute -3 into x and solve the equation.
When x= -3,
y= -(-3) +5
y= 3 +5
y= 8

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(9, 3) = 9. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 3 = 27. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen ninths minus five thirds = two ninths

Answer:
I'd say the answer is cube of a binomial, because when something is specifically raised to the 3rd power, that number is being cubed. (When you square a number it has an exponent of 2, whereas when you cube a number it has an exponent of 3.)

Determine if the statement is true or false.
Justify your response.
If one vertex of a slope triangle is at (0,0), the other vertex on the line will be the point that represents the simplified unit rate or slope
The point on the line where the simplified unit rate or slope is True will be the opposite vertex of a slope triangle if one vertex is at (0,0).
Explain about the Slope triangle?A slope triangle is a hypothetical triangle that aids in determining a line's or line segment's slope. The line whose slope you are interested in learning is the triangle's hypotenuse (the diagonal). The "rise" and "run" terms used in the slope formula are the two "legs" of the triangle. Rise/run is a slope.
The slope of a triangle with a slope is positive if the hypotenuse slopes uphill from left to right. The slope of a slope triangle is negative if the hypotenuse slopes downward from left to right.
This is the Greek letter delta, which stands for change. It can be applied to math or simply to make a statement shorter.

Answer:
d = mn/F
Step-by-step explanation:
F = mn/d
multiply both sides with d
d*F = mn/d*d
dF=mn
divide F from both sides
d/F = mn/F
So..
d = mn/F
Answer:
Given:
[tex] \boxed{ \mathsf{F = \frac{mn}{d} }}[/tex]
Divide both sides by "mn":
[tex] \mathsf{ \frac{F}{mn} = \frac{mn}{d \times mn} }[/tex]
The two mn's on the RHS gets canceled out. So we're left with:
[tex] \mathsf{ \frac{F}{mn} = \frac{1}{d} }[/tex]
Invert the fractions present on either side of the "equals" sign
(In other words, flip it on its head so its numerator becomes its denominator and vice):
[tex] \mathsf{ \frac{mn}{F} = \frac{d}{1} }[/tex]
Hence, we got the value of d:
[tex] \underline{\mathsf{ d= \frac{mn}{F} }}[/tex]
