1. One way to work mixture problems like this is to consider the effect of all sales being for the smaller amount. In that case, revenue would be 135*$185 = $24,975. That is $2250 less than actual revenue. For each large system sold instead of a small one, there is $50 in additional revenue. The $2250 in additional revenue requires that 2250/50 = 45 large systems be sold.

2. We know that Rafael's overtime pay is $912.60 - 40*$14.40 = 336.60. None of the offered answers computes to the correct pay amount.  

If you made a typo and the correct total pay is $921.60, then an overtime rate of 1.5 times base pay will require 16 hours of overtime; an overtime rate of 3 times base pay will only require 8 hours of overtime. Overtime hours = $921.60/$14.40 = 64 equivalent hours. Subtracting 40 hours of straight time, the resulting product of hours and multiplier will be 64 - 40 = 24. That is it could be 16 hours at 1.5 times, or 8 hours at 3 times.

3. One of the problems here is to figure the number of hours in a month. If you consider there to be 4 1/3 weeks in a month, Robin needs to work $3280/(13/3)/14.90 = 50.80 equivalent hours. The 10.80 equivalent overtime hours will be 10.80/1.5 = 7.20 clock hours, closest to 7.25 among the answers. (Other choices for weeks/hours in a month give answers that match none of those offered.)

4. $750/$19.50 = 38.46, closest to 38.50 among the answers offered.

Answer:

Step-by-step explanation:

Given: d= 12 and h= 14

formula for the volume of a cone:

V= (1/3) · π · r² · h

V= volume

r= radius

h= height

to find the radius of the cone, we will use this formula r = 1/2 · d

r = 1/2 · 12

r = 6

Now that we know the value of the radius we can now plug it in in our formula.

V= (1/3) · π · 6² · 14

V= 1π · 6² · 14 / 3

V= 1π · 2²· 3² · 14 / 3

V= 2² · 14 · 3π

V= 2² · 14 · 3π

V= 2² · 42π

V= 4 · 42π

V= 168π

V=527.79

The time needed for light to travel 42000 Km is 0.14 second.  

Given that,

The speed of the light is = 3 × 10⁸ m/s

Distance travelled by light is = 42000 km = 42 × 10⁶ m [since 1 km = 10³ m]

We have to find the time needed to travel the distance 42000 km by the light.

We know that from the velocity formula,

Speed = Distance/Time

Time = Distance/Speed

Time = (42 × 10⁶)/(3 × 10⁸) = 14 × 10⁻² = 0.14 second.

Hence the time needed for light to travel 42000 Km is given by 0.14 second.

The function d/dx (f/g) = 2 gives the value of c as -4.

The denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the square of the denominator, is how the Quotient Rule defines the derivative of a quotient.

Given:

f(x) = 1/2x and g(x) = 1/ (3x + c)

Using Quotient rule

d/ dx (f/g)

= g f' - f g- / g²

So, d/dx ( 3x+c / 2x )

Answer:

The answer is D

Step-by-step explanation:

The x-intercept is any point where y crosses 0 on a table graph.

The function is decreasing and at a maximum at t=2.

At t=2, the function C(t)=15te-.4t evaluates to approximately 9.42. To determine whether the function is at the inflection point, increasing, at a maximum, or decreasing, we need to examine its first and second derivatives. The first derivative is C'(t) = 15e-.4t(1-.4t) and the second derivative is C''(t) = -6e-.4t.
At t=2, the first derivative evaluates to approximately -2.16, indicating that the function is decreasing. The second derivative evaluates to approximately -3.03, which is negative, confirming that the function is concave down. Therefore, the function is decreasing and at a maximum at t=2.

The four pieces of chain necklaces into a single circle of 12 links, you need to open six links (1.5 links for each necklace) and then close two links, which will cost $18.

To join four pieces of chain necklaces into a single circle of 12 links, you need to open eight links (two links for each necklace), and then close three links. Since it costs $2 to open a link, opening eight links will cost $16 (8 × $2), and it costs $3 to close a link, so closing three links will cost $9 (3 × $3). Therefore, the total cost will be $16 + $9 = $25.

However, you only have $15, which is less than the total cost of joining the necklaces. Therefore, you need to find another solution to join the necklaces.

Answer:

Step-by-step explanation:

To find the percent you need to divide 1,170 by 2,600.

Using the P-value method of testing hypotheses with a significance level of 0.05, the sample provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.

To test the claim that the mean score of job applicants from the university is greater than 160, we will perform a one-sample t-test using the P-value method. The null hypothesis (H0) assumes that the mean score is equal to 160, while the alternative hypothesis (Ha) assumes that the mean score is greater than 160.

First, we calculate the test statistic, which is the t-value. The formula for the t-value is:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

Plugging in the given values, we have:

t = (183 - 160) / (12 /   √(25))

  = 23 / (12 / 5)

  = 23 * (5 / 12)

  ≈ 9.58

Next, we find the P-value associated with the test statistic. The P-value represents the probability of obtaining a test statistic as extreme as the observed value, assuming the null hypothesis is true. Since the alternative hypothesis is one-sided (greater than 160), we calculate the P-value by finding the probability of the t-distribution with 24 degrees of freedom being greater than the calculated t-value.

Consulting statistical tables or using software, we find that the P-value is very small (less than 0.0001).

Since the P-value (less than 0.0001) is less than the significance level (0.05), we reject the null hypothesis. This provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.

The third angle of the triangle is 80 degrees. If two angles in a triangle are 55∘ and 45∘, the third angle can be calculated by using the following formula:

Third angle = 180 - (Sum of the other two angles)

Let's put the given values in the above formula.

Third angle = 180 - (55 + 45)Third angle = 180 - 100

Third angle = 80Hence, the third angle of the triangle is 80 degrees.

A triangle is a closed figure consisting of three sides. The sum of the angles of a triangle is always equal to 180 degrees. This means that if two angles in a triangle are known, then the third angle can be calculated by subtracting the sum of the known angles from 180 degrees.

In this question, the two angles of the triangle are 55 degrees and 45 degrees. The third angle can be found by using the formula Third angle = 180 - (Sum of the other two angles). By substituting the given values in the formula, we get the third angle as 80 degrees.

g(4) = 1 * g(4), which means that q(4) is equal to g(4). y(-4) = f(-4) * h(-4) = 1 * (-4) = -4. Therefore, the values of q(4), y(-4), and y(4) are determined as follows: q(4) = g(4), y(-4) = -4, and y(4) = 0.

For the first part of the problem, we are given f(t) = u(t), g(t) = 2tu(t), and g(t) = f(t - 1) * g(t). To determine q(4), we need to substitute t = 4 into the equation g(t) = f(t - 1) * g(t). This gives us g(4) = f(3) * g(4). Since f(t) = u(t), we know that f(3) = u(3) = 1 because u(t) is a unit step function that equals 1 for t ≥ 0. Therefore, we have g(4) = 1 * g(4), which means that q(4) is equal to g(4).

For the second part of the problem, we are given f(t) = u(-t), h(t) = tu(-t), and y(t) = f(t) * h(t). To determine y(-4) and y(4), we substitute t = -4 and t = 4 into the equation y(t) = f(t) * h(t). For y(-4), we have y(-4) = f(-4) * h(-4). Since f(t) = u(-t), we have f(-4) = u(4) = 1 because u(t) is a unit step function that equals 1 for t ≥ 0. Similarly, h(-4) = -4u(4) = -4. Therefore, y(-4) = f(-4) * h(-4) = 1 * (-4) = -4.

Similarly, for y(4), we have y(4) = f(4) * h(4). Since f(t) = u(-t), we have f(4) = u(-4) = 0 because u(t) is a unit step function that equals 0 for t < 0. Thus, y(4) = f(4) * h(4) = 0 * h(4) = 0.

Therefore, the values of q(4), y(-4), and y(4) are determined as follows: q(4) = g(4), y(-4) = -4, and y(4) = 0.

Substituting the values, we get u = v/m, and using the mirror formula, the distance of the object from the mirror is 10.15 cm.

Given data: Radius of curvature of a concave mirror, r = +31.5 cm Magnification produced by the mirror, m = 3.40

We know that the formula for magnification is given by:

m = v/u where, v = the distance of the image from the mirror u = the distance of the object from the mirror We also know that the formula for the focal length of the mirror is given by :

f = r/2where,f = focal length of the mirror

Using the mirror formula:1/f = 1/v - 1/u

We know that a concave mirror has a positive focal length, so we can replace f with r/2.

We can now simplify the equation to get:1/(r/2) = 1/v - 1/u2/r = 1/v - 1/u

Also, from the given data, we have :m = v/u

Substituting the value of v/u in terms of m, we get: u/v = 1/m

So, u = v/m Substituting the value of u in terms of v/m in the previous equation, we get:2/r = 1/v - m/v Substituting the given values of r and m in the above equation, we get:2/31.5 = 1/v - 3.4/v Solving for v, we get: v = 22.6 cm Now that we know the distance of the image from the mirror, we can use the mirror formula to find the distance of the object from the mirror.1/f = 1/v - 1/u

Substituting the given values of r and v, we get:1/(31.5/2) = 1/22.6 - 1/u Solving for u, we get :u = 10.15 cm

Therefore, the distance of the mirror from the face is 10.15 cm. The units are centimeters (cm).Answer: 10.15 cm.
