Based on the fact that the two numbers multiply to 2,400 and add up to -16, the numbers are undefined.

Assume that one of the numbers is x and the other number is y, the system of equations to represent this is given that the two numbers add up to -16 and multiplying to 2,400:
x + y = -16

xy = 2,400

Expressing y in terms of x :

xy = 2,400

y = 2,400 / x

Solving for x gives:

x + y = -16

x + (2,400 / x) = -16

x = 0

y = 0

The problem given in the question is wrong because the results of x and y are undefined.

The value of t for the angles of the given triangle will be 30.67.

The straight angle is equal to the total of the angles of a triangle. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle. For a very long period, it was unknown if there were any alternative geometries for which the total is different.

The triangle has three sides and is a two-dimensional figure having the sum of the angles of 180 degrees.

In the given image the three angles are 2t, t + 8, and t - 12. The value of t will be calculated as:-

2t + t + 8 + t - 12 = 180

4t - 4 = 180

4t = 184

t = 184 / 4

t = 30.67

Therefore, the value of t for the angles of the given triangle will be 30.67.

The inequality expression given as |-4/3x - 5| > 19 has a solution of 10.5 < x < -18

From the question, the inequality is given as

|-4/3x-5|>19

Rewrite properly as

|-4/3x - 5| > 19

Remove the absolute bracket

So, we have the following representation

-19 > -4/3x - 5 > 19

Add 5 to all sides of the inequality

So, we have

-14 > -4/3x > 24

Multiply through by -3/4

So, we have

10.5 < x < -18

Hence, the solution to the expression is 10.5 < x < -18

Using Venn diagram, if a student is chosen randomly, (a) the probability that he or she is not in any of the language classes is 0.5, (b) the probability that he or she is taking exactly one language class is 0.32, and (c) if 2 students are chosen randomly, the probability that at least 1 is taking a language class is 0.753.

Venn diagram is a diagram used to present the relationship between sets in a logical form. (See attached image)

Let A = students in the Spanish class = 28

B = students in the French class = 26

C = students in the German class = 16

Hence, the probability of each class is:

P(A) = 28/100 = 0.28

P(B) = 26/100 = 0.26

P(C) = 16/100 = 0.16

P(A ∩ B) = 12/100 = 0.12

P(B ∩ C) = 6/100 = 0.06

P(A ∩ C) = 4/100 = 0.04

P(A ∩ B ∩ C) = 2/100 = 0.02

(a) P(not A, B, C) = 1 - P(A ∪ B ∪ C)

P(not A, B, C) = 1 - [P(A) + P(B) + P(C) - P(A ∩ B) - P(B ∩ C) - P(A ∩ C) + P(A ∩ B ∩ C)]

P(not A, B, C) = 1 - (0.28 + 0.26 + 0.16 - 0.12 - 0.06 - 0.04 + 0.02)

P(not A, B, C) = 1 - 0.5

P(not A, B, C) = 0.5

(b) P(A, B, C only) = P(A only) + P(B only) + P(c only)

P(A, B, C only) = [P(A) - P(A ∩ B) - P(A ∩ C) + P(A ∩ B ∩ C)] + [P(B) - P(A ∩ B) - P(B ∩ C) + P(A ∩ B ∩ C)] + [P(C) - P(B ∩ C) - P(A ∩ C) + P(A ∩ B ∩ C)]

P(A, B, C only) = (0.28 - 0.12 - 0.04 + 0.02) + (0.26 - 0.12 - 0.06 + 0.02) + (0.16 - 0.06 - 0.04 + 0.02)

P(A, B, C only) = 0.14 + 0.10 + 0.08

P(A, B, C only) = 0.32

(c) P = 1 - (50/100 x 49/99)

P = 1 - (49/198)

P = 149/198

P = 0.753

To complete the problem, here are the questions:

(a) If a student is chosen randomly, what is the probability that he or she is not in any of the language classes?

(b) If a student is chosen randomly, what is the probability that he or she is taking exactly one language class?

(c) If 2 students are chosen randomly, what is the probability that at least 1 is taking a language class?

In the picture there is a prism with measures. The surface area of prism is 156.

Given that,

In the picture there is a prism with measures.

We have to find the surface area of prism.

The surface area of prism=(2×base area)+(Base perimeter×height)

The base is trapezoid

So, the area of trapezoid is (a+b)/2×h

=(6+12)/2×4

=18/2×4

=9×4

=36

Here base area we got is 36.

Now, we find the perimeter of trapezoid is a+b+c+d

=6+12+5+5

=18+10

=28

Here, base perimeter we got is 28.

Now surface area of prism is

=(2×36)+(28×3)

=72+84

=156

Therefore, the surface area of prism is 156.

Mang Efren's present age is 30 years.

Let's assume the present age of Mang Efren's son is x years.

Mang Efren is presently 5 times as old as his son.

So, Mang Efren's present age = 5x years

Four years ago,

Mang Efren's son's age = x - 4 years.

Mang Efren's age = 5x - 4 years

According to the question, four years ago, the product of their ages was 52.

From this information, we will create an equation.

(x - 4)(5x - 4) = 52

5x² - 4x - 20x + 16 = 52

5x² - 24x + 16 - 52 = 0

5x² - 24x - 36 = 0

Solving the quadratic equation to obtain the value of x,

5x² - 30x + 6x - 36 = 0

5x(x -6) + 6(x - 6) = 0

(5x - 6)(x - 6) = 0

x = 6

So, Mang Efren's present age is 5 × 6 = 30 years.

Since two angles on a straight line add up to 180, I used the angles given to find the adjacent angles to it by subtracting those angles from 180. Then, since the angles of a triangle add up to 180, I used the angles I just solved for to find the angle that is adjacent to n. I did the same thing I did to the first two angles by subtracting it from 180 to find n, which was 69 degrees

For the quadratic equation:

x^2 + 7x = 8x + 12

The two solutions are:

x = 4

x = -3

I'm only solving the first question, as it is how the guidelines say.

Here we have the quadratic equation:

x^2 + 7x = 8x + 12

First, we can rewrite this equation as:

x^2 + 7x - 8x - 12 = 0

x^2 - x - 12 = 0.

Using Quadratic formula we can see that the solutions (or zeros of the quadratic) are:

x = (1 ± √(  (-1)^2 - 4*1*-12))/(2*1)

x = (1 ± 7)/2

Then the two solutions are:

x = (1 + 7)/2 = 4

Clay and Jason are 600 feet far apart.

When an object goes above the surface, the altitude is measured as +ve and when an object goes below the surface, the altitude is measured as -ve.

Since Clay is flying a helicopter at an altitude of 400 feet in the air,

The Value of altitude of Clay = +400

Since, Jason is diving 200 feet below the surface,

The Value of altitude of Jason = -200

The the distance between Clay and Jason = (The Value of altitude of Clay) - (The Value of altitude of Jason)

= +400 - (-200)

= 400 + 200

= 600 feet

Therefore, the distance between Clay and Jason is 600 feet.

Answer: 51

Step-by-step explanation:

By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)

In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:

s' = (v' - v) · t

Where:

Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:

s' = (210 - 120) · (30 / 3600)

s' = 3 / 4 mi

The distance surplus of the average race car is equal to 3 / 4 miles.
