Eric's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Eric $5.50 per pound, and type B coffee costs $4.40 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $762.30. How many pounds of type A coffee were used?
115.2 pounds of type A coffee were used.
What is the solution of the equation?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
Let the number of pounds of type A coffee be x and the number of pounds of Type B coffee be y.
According to the question, the equations are,
5.50x + 4.40y = 762.30
x = 4y
So, the solution of the equation is obtained as follows:
5.50(4y) + 4.40y = 762.30
26.40y = 762.30
y = 762.30/26.40
y = 28.8 pounds
x = 4*28.8 = 115.2 pounds

Find (f. g)(x).
Answer:
[tex](f \cdot g)(x)[/tex] = [tex]2x^2 -1[/tex]
Step-by-step explanation:
[tex](f \cdot g)(x)[/tex], read as "f of g of x", means we have to use the function [tex]\bf g(x)[/tex] as input for the function [tex]\bf f(x)[/tex]. This means, we have to replace the [tex]x[/tex] in the definition of [tex]f(x)[/tex] with [tex]g(x)[/tex].

Mark the vertex and graph the axis of symmetry of the function.
f(x) = (x – 2)2 – 25
Answer:
Vertex (2 , -25)
Axis of symmetry: x = 2
Step-by-step explanation:
Vertex of parabola:The vertex is the highest point if the parabola open downwards and the lowest point if the parabola opens upward.
f(x) = (x - 2)² - 25
The given quadratic function is in vertex form.
f(x) = a(x - h)² + k
Here, (h , k) is the vertex of the parabola.
h = 2 ; k = -25
[tex]\sf \boxed{\bf Vertex (2 , -25)}[/tex]

The height of a door is 1.5 feet longer than its width, and its front area is 1516.5 square feet. Find the width and height of the door.
Answer:
For an exact answer the width would be the square root of 1011 and the length would be 1.5x the square root of 1011.
Step-by-step explanation:
A = lw
1516.5 = w(1.5)w
1516.5 = 1.5w^2 Divide both sides by 1.5
1011 = w^2 Take the square root of each side
Square root of 1011 = w.

Find the time required for an investment of 5000 dollars to grow to 6000 dollars at an interest rate of 7.5 percent per year, compounded quarterly.
Answer:
2.4536 years
Step-by-step explanation:
compound formula:
A=P*(1+r/n)^nt
A = 6000
P = 5000
r = rate
n = 4 times per year compounded
t = time in years
6000 = 5000(1 + .075/4)^4t
divide both sides by 5000
1.2 = (1.01875)^4t
log both sides
log(1.2) = 4t * log(1.01875)
solve for t
t = 2.4537 years

Using the Poisson distribution, there is a 0.9978 = 99.78% probability that there will be 4 or more customers at this bank in one hour.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.A bank gets an average of 12 customers per hour, hence the mean is [tex]\mu = 12[/tex].
The probability that there will be 4 or more customers at this bank in one hour is:
[tex]P(X \geq 4) = 1 - P(X < 4)[/tex]
In which:
P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
Then:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-12}12^{0}}{(0)!} \approx 0[/tex]
[tex]P(X = 1) = \frac{e^{-12}12^{1}}{(1)!} \approx 0[/tex]
[tex]P(X = 2) = \frac{e^{-12}12^{2}}{(2)!} = 0.0004[/tex]
[tex]P(X = 3) = \frac{e^{-12}12^{3}}{(3)!} = 0.0018[/tex]
Then:
P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0 + 0 + 0.0004 + 0.0018 = 0.0022.
[tex]P(X \geq 4) = 1 - P(X < 4) = 1 - 0.0022 = 0.9978[/tex]

Seven more than twice a number is six less than three times the same number
Answer:
13
Step-by-step explanation:
7+2x=3x-6
knowing this then you solve it
Step-by-step explanation:
7 more = + 7
twice a number = 2*x = 2x
6 less = -6
3 times the same number = 3 * x = 3x
Putting this together we get:
2x + 7 = 3x - 6
subtract two from both sides to isolate x
(-2x) + 2x + 7 = 3x - 6 (-2x)
7 = x - 6
add 6 to both sides to get your answer

The equation of the asymptote is y = 3x - 5. The correct answer is option C
What is Asymptote of an Hyperbola ?The distance from a point and the distance to a line in hyperbola is known as asymptote. The general equation is [tex]x^{2}/ a^{2} - y^{2}/b^{2} = 1[/tex]
From the given equation of hyperbola, which is
[tex]\frac{(x - 2)^{2}}{4}[/tex] - [tex]\frac{(y - 1)^{2} }{36}[/tex] = 1
The center (h , k) of the hyperbola = C(2, 1)
