If a chemical company makes two brands of antifreeze. The first brand is 20% pure antifreeze, and the second brand is 95% pure antifreeze. The number of gallons each brand of antifreeze must be used is: 56 gallons of 20% antifreeze and 84 gallons of 95% antifreeze.
Number of gallons for each brand of antifreezeLet call x = The amount of 20% pure antifreeze needed
Let 140 - x = amount of 95% antifreeze needed
Hence,
x gallons of 20% antifreeze + (140-x) gallons of 95% = 140 gallons of 65%
Thus,
.20x + .95(140-x) = .65(140)

At a price of $180 there is demand for 2520 items and a supply of 1440 items. At a price of $330 there is demand for 1470 items and a supply of 2640 items. Assuming supply and demand are linear, find the equilibrium price and quantity.
Assuming supply and demand are linear, the equilibrium price is equal to $252 and the equilibrium quantity is equal to 2,016 items.
What is a linear function?A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
First of all, we would determine a linear function for both supply and demand by finding the slope using this formula as follows:
[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope,\;m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Note: price (p) in dollars would be the output and quantity (q) would be the input.
For supply, the points include the following:
Points (p, q) = (1,440, 180).Points (p, q) = (2640, 330).Slope, m = (330 - 180)/(2640 - 1440)
Slope, m = 150/1200
Slope, m = 1/8.
Next, we would find the y-intercept at (1,440, 180):
p = qm + c
180 = 1/8(1440) + c
180 = 180 + c
c = 0.
Therefore, the supply equation is p = q/8.
For demand, the points include the following:
Points (p, q) = (2,520, 180).Points (p, q) = (1,470, 330).Slope, m = (330 - 180)/(1,470 - 2,520)
Slope, m = 150/-1,050
Slope, m = -1/7.
Next, we would find the y-intercept at (2,520, 180):
p = qm + c
180 = -1/7(2,520) + c
180 = -360 + c
c = 180 + 360.
y-intercept, c = 540.
Therefore, the demand equation is p = -q/7 + 540.
In order to find the equilibrium price and quantity, we would set the supply equal to the demand:
q/8 = -q/7 + 540
Multiplying all through by 56, we have:
7q = -8q + 30,240
15q = 30,240
q = 30,240/15
Equilibrium quantity, q = 2,016 items.
For the equilibrium price, we have:
p = q/8
p = 2,016/8
Equilibrium price, p = $252.

Answer:x= −12/15
Step-by-step explanation:
Answer:
f(-4) = 24
Step-by-step explanation:
In order to find f(-4), set the value of x as -4 in the equation.
Given equation:
f(x) = 3(4 - x)
Substitute x = -4:
f(-4) = 3(4 - (-4))
f(-4) = 3(4 + 4)
f(-4) = 3(8)

A side of the triangle below has been extended to form an exterior angle of 125. Find the value of x
Answer:
55°
Step-by-step explanation:
The angle that is represented with x and the exterior angle with a measure 125° are supplementary angles.
As known the sum of supplementary angles is 180 so the value of x:
180 - 125 = 55 and
x = 55 is the answer to the question.
Tripling the radius of a cylinder find the dimensions, surface area, before change and after change. Help ASAP please !
The dimensions before tripling the radius of the cylinder are:
radius = 2 and height = 7 yd
and surface area = 113.1
The dimensions after tripling the radius of the cylinder are:
radius = 6 and height = 7 yd
surface area = 490.08
Given, we know that the dimensions are:
radius = 2 and height = 7 yd
therefore, surface area = 2πrh + 2πr²
= 2π2×7 + 2π(2)²
= 2×22/7×14 + 2π×4
= 88 + 25.12
= 113.1
After tripling the radius, we get:
radius = 6 and height = 7 yd
therefore, surface area = 2πrh + 2πr²
= 2π6×7 + 2π(6)²
= 2×22/7×42 + 2π×36
= 264 + 226.08
= 490.08
Hence we get the before and after dimensions of the cylinder.

Which of the following sets is NOT closed under addition.
A) Natural Numbers
B) Whole numbers
C) Integers
D) Odd numbers
The odd numbers do not follow the closure property of addition.
What is a closure property of addition?
The closure property of addition states that when any two numbers from the set of reals are added, the result will always be a real number. For example 2 + 3 = 5
Explanation
When we add any two natural numbers, the result is always a natural number, i.e. 2 + 1 = 3. Thus, it follows the closure property of addition.
When we add any two whole numbers, the result is always a whole number, i.e. 3 + 0 = 3. Thus, it follows the closure property of addition.
When we add any two integers, the result is always an integer, i.e. 2 + (-5) = -3. Thus, it follows the closure property of addition.
When we add any two odd numbers, the result is not an odd number, i.e. 3 + 1 = 4. Thus, it does not follow the closure property of addition.
Hence, the odd numbers do not follow the closure property of addition.

The final amount in Gigi's amount after two years is $637.102.
Compound interest is also known as interest on principal and interest is the practice of adding interest to the principal amount of a loan or deposit.
Gigi opened a savings account.
The principal amount she deposited, P = $600
The interest rate, r = 3% = ( 3 / 100 ) = 0.03
The formula for the compound interest is given as:
[tex]A=Pe^{rt}[/tex]
Where A is the final amount, P is the principal amount, r is the interest rate, and t is the time in years.
Then the amount in the account after t = 2 years will be:
[tex]A=Pe^{rt}\\A = 600 \times e^{(0.03 \times 2)}[/tex]
A = 600 × e⁰·⁰⁶
A = 600 × 1.06183654655
A = 637.101927927
A = $637.102
