Answer:

15/20 or 3/4

Step-by-step explanation:

9 green marbles(GM) + 5 yellow marbles(YM) + 6 red marbles(RM) = 20 marbles total(TM)

GM = 9/20

YM = 5/20

RM = 6/20

TM = 20/20

For the probability of choosing a GM or RM you just add their respective values:

9/20 + 6/20 = 15/20

Simplified this answer is 3/4

Probability of selecting a green or red marble is 3/4

Given that;

Number of green marble = 9

Number of red marble = 6

Number of yellow marble = 5

Find:

Probability of selecting a green or red marble

Computation:

Probability of selecting a green = 9 / [9 + 6 + 5]

Probability of selecting a green = 9 / 20

Probability of selecting a red = 6 / [9 + 6 + 5]

Probability of selecting a green = 6 / 20

Probability of selecting a green or red marble = [9/20] + [6/20]

Probability of selecting a green or red marble = 15 / 20

Probability of selecting a green or red marble = 3/4

Answer:

80 min = 1 hr 20 min

1 hr 20 min after 1:57 pm is 3:17 pm.

Between 3:17 pm and 4:00 pm there are 43 minutes.

Tony has 43 minutes between the end of the project and the beginning of band practice.

Step-by-step explanation:

Tony had 46 minutes between the end of the project and the beginning of band practice.

To solve this problem, we need to calculate the time Tony finished his math project and then determine how much time there was between the end of the project and the start of his band practice.

1. First, we find the time Tony finished his math project. Since he started at 1:57 pm and worked for 80 minutes, we add 80 minutes to 1:57 pm.

2. To add 80 minutes to 1:57 pm, we convert 80 minutes into hours and minutes. There are 60 minutes in an hour, so 80 minutes is 1 hour and 20 minutes (since 60 minutes is 1 hour and 20 minutes is the remainder).

3. Adding 1 hour and 20 minutes to 1:57 pm gives us 3:17 pm (1:57 pm + 1 hour = 2:57 pm, and then adding the remaining 20 minutes gives us 3:17 pm).

4. Now, we need to find out how much time is between 3:17 pm (when Tony finished his project) and 4:00 pm (when his band practice starts).

5. From 3:17 pm to 4:00 pm is a duration of 45 minutes (from 3:17 pm to 4:00 pm is 43 minutes, plus the 2 minutes from 3:17 pm to 3:19 pm).

6. However, we must remember that Tony started at 1:57 pm, which is 1 minute before 1:58 pm. So, we need to add this 1 minute to the total time between the end of the project and the start of band practice.

7. Therefore, the total time Tony had between finishing his math project and starting band practice is 45 minutes + 1 minute = 46 minutes.

Answer:

x=54

Step-by-step explanation:

Because one side of the triangle is tangent (touching) to the circle while the other is the radius itself, we can conclude that the angle that is not named is 90°.

Knowing this, we can then add 36° and 90° to get 126°.

All of the angles in a triangle add up to 180°; therefore, we can subtract 126° from 180° to get 54°.

I really hope this helps and explains it well!

Answer:

x = 54°

Step-by-step explanation:

Since the lower segment is a tangent to the circle then

the angle between the tangent and the diameter is right.

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 known angles from 180 for x, that is

x = 180° - (90 + 36)° = 180° - 126° = 54°

Easiest way, pick any two even numbers in that range, they will have at least 2 as a common factor.

Answer:

A

Step-by-step explanation:

x² + 10x + 24 = 0

Here, a = 1, b = 10, c = 24.  Factoring using the AC method:

ac = 1×24 = 24

Factors of 24 that add up to 10 are +4 and +6.

Therefore:

(x + 4) (x + 6) = 0

x + 4 = 0, x + 6 = 0

x = -4, x = -6

The roots are -4 and -6.  Added together:

-4 + -6 = -10

Answer A.

The required sum of the roots of the quadratic equation x² + 10x + 24 = 0 is -10.

In mathematics, the roots of an equation are the values of the variable that satisfy the equation.

Here,
To find the roots of the quadratic equation x² + 10x + 24 = 0, we can use the quadratic formula,

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 1, b = 10, and c = 24. Substituting these values, we get:

x = (-10 ± √(10² - 4(1)(24))) / (2(1))

x = (-10 ± √4) / 2

x = -5 ± 1

Therefore, the roots of the quadratic equation are x = -4 and x = -6.

The sum of these roots is -4 + (-6) = -10

Therefore, the sum of the roots of the quadratic equation x² + 10x + 24 = 0 is -10.

Answer:

The diagonal of a square with 90 ft. per side is 127.28 which should be rounded down to 127 and the throw from 2nd to 3rd is 90 ft totaling 217 ft

The baseball moves 217.4 feet across the field in total.

Measured from the middle of the backstop to the apex of the home plate. Place second base in the centre by drawing a line from the backstop's centre point over the pitcher's mound, through the apex. The distance that needs to be measured is between the centre of the second base and the top of the home plate.

So we are given that each side of a square is 90 feet.

By finding how far the ball will travel, we are basically finding the distance from 2nd base to home

Well, let's picture a baseball field, and we find out that they are diagonal across from one another.

Well, let's draw a diagonal connecting home to 2nd base.

Since the field is a square, it has a right angle at 1st base

We now know 2 legs in a right triangle, which calls for the Pythagorean Theorem

(You could also do a 45-45-90 special right triangle, which would give you the answer very quickly)

So we have 90²+90²=c²

Which is

16200=c²

We are finding c

, so √16200=c

We can simplify this to √162⋅100 which is 10√162

Then we can simplify this to 10√81⋅2, that is 10⋅9√2

Finally, we multiply the values outside of the root to get = 90√2

the throw from 2nd to 3rd is 90 ft

total distance covered = 90 + 90√2

total distance covered = 217.4

Therefore, baseball travels in the field a total of 217.4 feet

Answer:

The point that is being intersected is (4,2).

The answer is x=8.6 units

After simplifying the fraction, we find that x = 7/17.

In
ΔABC, J is on AB, K is on BC, and JK is parallel to AC. We're given that JB = 5, AJ = 17, BK = x+4, and KC = 5x. By the properties of parallel lines and similar triangles, we can state that ΔAJK ~ ΔACB. Considering the sides of these triangles, the ratios of corresponding sides must be equal, which gives us the proportion:

AJ/JB = AC/BC

Substituting in given values and variables, we get:

17/5 = (17 + 5)/(5x + x + 4)

Solving for x, we multiply each side by the denominators to eliminate the fraction:

17(5x + x + 4) = 5(22)

85x + 17x + 68 = 110

102x + 68 = 110

102x = 42

x = 42/102

x = 7/17

After simplifying the fraction, we find that x = 7/17.

Answer:

The graph c.

Step-by-step explanation:

We know from the function f(x) = 5sin(-2t) three things:

1. The amplitude is 5.

2. The period is π.

3. Because of the negative in the argumen, the graph will be reflected over the y-axis (Compared to the graph of sin(x))

Then, evaluating all the functions we find:

1. All of graphs have an amplitude of 5.

2. The graph b has a period of 2π.

3. The graph a is not reflected over the y-axis.

Then, the correct graph is the graph letter C.

The Graph of the function f(t) = 5 sin(-2t) is graph (b) in the image you provided.

This can be seen by noting that the function f(t) = 5 sin(-2t) is a sine function with a period of π, amplitude of 5, and horizontal shift of π/2 to the right. Graph (b) in the image matches these characteristics.

Amplitude: The amplitude of the function is 5, which is the absolute value of the coefficient in front of the sine term.

Period: The period of the function is π/2, which is the reciprocal of the absolute value of the coefficient multiplying the t term.

Phase shift: The function has a phase shift of π, which means that the graph is shifted to the left by π units.

The graph on the left has all of these features:

It has an amplitude of 5.

It has a period of π/2.

It is shifted to the left by π units.

The other graphs in the image do not match these characteristics:

Graph (a) has a period of 2π, not π.

Graph (c) has an amplitude of 1, not 5.

Graph (d) has a horizontal shift of −π/2, not π/2.

Therefore, the correct graph is graph (b).

Step-by-step explanation:

Slope is rise/run

This graphs shows the line going up by 2 and to the right 3

The graph that has a slope equal to 2/3 is Option(C) .

Slope of a straight line is defined as the inclination of the line with respect to the coordinate axis. The slope is also measure of the tangent of angle with which the line is inclined to the axis.

Slope of a straight line can be found using two given points say (x1,y1) and (x2,y2).

Slope (m) = (y2 - y1) / (x2 - x1) .

We check the graph at Option(C).

The coordinate of the point where the graph has 2 units distance with the y-axis is (4.5,2) and the coordinate of the point where the graph has 3 units distance with the x-axis is (1.5,0).

We have y2 = 2 , y1 = 0, x1 = 4.5, x2 = 1.5 .

Thus slope = (y2  y2)/(x2 - x1) = (2 - 0)/(4.5 - 1.5) = 2/3

Therefore, the graph that has a slope equal to 2/3 is the graph in  Option(C) .

tan (x) + x(sec^2(x)) = 0

Solving this equation (using a graphing calculator set to radians), it is only true when x = 0.

So, 0 is a critical point of this function.

The derivative of tan(x) is sec^2(x) and the critical points for xtanx occur at x = π/2 + nπ.

Derivative of tan(x) can be found by using the formula: d/dx(tan(x)) = sec^2(x). Critical points for xtanx can be obtained by setting the derivative equal to zero and solving for x. In this case, the critical points are where sec^2(x) = 0, which occurs when x = π/2 + nπ, where n is an integer.
