To get the secret blend, you should mix 18 pounds of the Rift Valley coffee with the 60 pounds of Mexican Shade Grown coffee.
Explanation:To find out how many pounds of the Rift Valley blend you should mix with the 60 pounds of Mexican Shade Grown coffee, we need to set up a proportion based on the ratio of the two blends. The ratio of the Mexican Shade Grown blend to the Rift Valley blend is 80:24, which can be simplified to 10:3. We can then set up the proportion: 10/3 = 60/x. By cross-multiplying, we get 10x = 180. Dividing both sides by 10, we find that x = 18. Therefore, you should mix 18 pounds of the Rift Valley coffee with the 60 pounds of Mexican Shade Grown coffee to get your secret blend.

Write an equation for a rational function with: vertical asymptotes at x = -4 and x = 4 x-intercepts at x = -6 and x = 5 horizontal asymptote at y = 8
A rational function with the required characteristics is f(x) = 8(x + 6)(x - 5) / (x + 4)(x - 4), considering vertical asymptotes, x-intercepts, and a horizontal asymptote.
Explanation:To write an equation for a rational function with given characteristics, we need to incorporate the vertical asymptotes, x-intercepts, and horizontal asymptote into our function.
Firstly, vertical asymptotes at x = -4 and x = 4 suggest that the denominator of our function will be in the form (x + 4)(x - 4), as setting x to -4 or 4 will make the denominator zero, which creates the asymptotes.
Secondly, x-intercepts at x = -6 and x = 5 indicate that the numerator will have factors that become zero at these x-values. Hence, the numerator should be(x + 6)(x - 5).
Finally, for the function to have a horizontal asymptote at y = 8, the degree of the numerator and denominator must be the same, and the leading coefficients of the numerator and denominator must have a ratio that equals 8. To achieve the horizontal asymptote, we multiply the numerator by 8, thus the leading coefficients of the numerator and denominator are in the ratio 8:1.
Combining all these elements gives us our rational function: f(x) = 8(x + 6)(x - 5) / (x + 4)(x - 4)

If the police have 9 suspects how many different ways can they select 5 for a lineup
The number of ways 5 suspects can be selected from 9 by the police is 126.
The number of ways the police can select 5 suspects from 9 is calculated using combinations. In this case, it is a combination problem because the order in which the suspects are selected does not matter. The formula for combinations is:
C(n, k) = n! / (k! * (n - k)!)
where n is the total number of suspects and k is the number of suspects to be selected.
Therefore, substituting n = 9 and k = 5 into the formula:
C(9, 5) = 9! / (5! * (9 - 5)!)
C(9, 5) = 126 ways
Mary babysits for $4 per hour. She also works as a tutor for $7 per hour. She wants to make at least $65 dollars. She is only allowed to work 13 hours per week. Write and graph a system of inequalities to represent this situation.
Answer:
inequalities are x + y ≤ 13 and 4x + 7y ≥ 65
Step-by-step explanation:
Given: Mary babysits for $4 per hour. She also works as a tutor for $7 per hour. She wants to make at least $65 dollars. She is only allowed to work 13 hours per week.
We have to write and graph the system of inequalities to represent this situation.
Let she babysits for x hours per week
and she works as a tutor for y hours per week
Then given she is allowed to work for 13 hours per week.
this inequality is stated as x + y ≤ 13
Mary babysits for $4 per hour if she babysits for x hours then she get 4x
She also works as a tutor for $7 per hour if she teach for y hours then she get 7y
also, she wants to make at least $65 dollars.
Then, this inequality is represented as 4x + 7y ≥ 65
Plotting of this two inequality is represented as graph shown below.

Two airplanes leave chicago's midway airport at the same time, traveling in opposite directions. one travels at 25 miles per hour faster than the other. after 2 hours they are 490 miles apart. find the speed of each airplane.
Final answer:
The first airplane travels at 110 miles per hour, and the second airplane travels at 135 miles per hour.
Explanation:
The question deals with two airplanes leaving Chicago's Midway Airport at the same time and heading in opposite directions.
One travels at a speed that is 25 miles per hour faster than the other.
After 2 hours, they are 490 miles apart, and we need to find the speed of each airplane.
Let's define the speed of the slower airplane as x miles per hour.
Then, the faster airplane's speed would be x + 25 miles per hour.
Since they are traveling in opposite directions for 2 hours, we can set up the equation:
2x + 2(x + 25) = 490
Solving for x will give us the speed of the slower airplane, and x + 25 will give us the speed of the faster airplane.
2x + 2x + 50 = 490
4x + 50 = 490
4x = 440
x = 110
Thus, the speed of the slower airplane is 110 mph, and the faster airplane is 135 mph (110 mph + 25 mph).

P(x) = x2 – 1 and q(x)=5(x-1), which expression is equivalent to (p – q)(x)?
Answer: The required expression is [tex]x^2-5x+4.[/tex]
Step-by-step explanation: We are given that
[tex]p(x)=x^2-1,\\\\q(x)=5(x-1).[/tex]
We are to find the expression that is equivalent to (p-q)(x).
We know that for any two functions f(x) and g(x), we have
[tex](f-g)(x)=f(x)-g(x).[/tex]
Therefore we get
[tex](p-q)(x)\\\\=p(x)-q(x)\\\\=(x^2-1)-(5(x-1))\\\\=x^2-1-5x+5\\\\=x^2-5x+4.[/tex]
Thus, the required expression is [tex]x^2-5x+4.[/tex]
Jack and jill ran a 200 meter race. jill ran the race in in 25 seconds and won by 1010 âmeters; that is jack had run only 190190 meters when jill crossed the finish line. they decide to raceâ again, but this time jill starts 1010 meters behind the starting line. assuming that both runners run at the same pace asâ before, who will win the second race and by how manyâ seconds?
the speed of jack = 190m/25s
= 7.6 m/s
the speed of jill = 200m/25s = 8 m/s
the distance travelled by jack in 2nd race= 200m
the distance travelled by jill in 2nd race= 210m
the time taken by jack in 2nd race = 200m/(7.6 m/s) = 26.3158
s
the time taken by jill in 2nd race = 210m/(8 m/s) = 26.25 s
therefore jill will still win and lead by 26.3158s – 26.25s = 0.0658 seconds

Given △ABC≅△JKL , m∠B=55° , and m∠L=25° , what is the measure of ∠J ? Enter your answer in the box.
Answer:
m∠J = 100° is the answer.
Step-by-step explanation:
Given : ΔABC ≅ ΔJKL,
m∠B = 55°
m∠L = 25°
To find : ∠J
Since in both the triangles ABC and JKL
m∠A ≅ m∠J
m∠B ≅ m∠K = 55°
m∠C ≅ m∠L = 25°
Since measure of ∠K and ∠L are known then we can calculate the third angle j
m∠J + m∠K + m∠L = 180°
55° + 25° + m∠J = 180°
80° + m∠J = 180°
m∠J = 180 - 80
= 100°
Therefore, m∠J = 100° is the answer.

carlotta is constructing an equilateral triangle. she has already constructed the line segment and arc shown.
Answer:
Place the point of the compass on point Q and draw an arc that intersects the first arc, using the same width for the opening of the compass as the first arc.
Step-by-step explanation:
She is constructing an equilateral triangle. This means that all 3 sides must be congruent. She has drawn an arc by placing her compass on point P and setting it to the width of segment PQ. This arc passes through point Q.
In order to ensure that the sides are congruent, she must keep her compass the same width. She will now go to the opposite end of the segment, point Q, and construct an arc that runs through point P. The goal is to intersect her first arc at a point that will serve as the third vertex of the triangle.
The next step in constructing an equilateral triangle after drawing the line segment and the first arc is;
Option B; Place the point of the compass on point Q and draw an arc that intersects the first arc using the same width for the opening of the compass as the first arc.
To answer this question, we will enumerate all the steps required to construct an equilateral triangle.
Step 1; Construct a line segment PQ to serve as the length of the side of the equilateral triangle and label the 2 endpoints P and Q.
Step 2; Place one leg of the compass at point P and with the other leg at point Q, swing an arc above line PQ
Step 3; Without Changing the width of the compass, place the first leg at point Q and with the second leg now at point P, swing another arc to intersect the first arc.
Step 4; Label the point of intersection R and draw a straight line from P to R and from Q to R to complete the equilateral triangle.
Looking at the given options, the one that tallies with step 3 which is the next step for the question is Option B.
