Answer:

5 seconds

Step-by-step explanation:

d = 16t^2

You are given the distance, d, and you need to find the time, t. Replace d with the given distance, 400 ft.

d = 400

400 = 16t^2

Switch sides.

16t^2 = 400

Divide both sides by 16.

t^2 = 25

Take the square root of both sides.

t = 5

Answer: 5 seconds

Answer: could you please be more clear..?

Step-by-step explanation:

The probability of drawing a red marble followed by a blue marble, without replacement, is approximately 0.083.

The question is about probability in a scenario where there's no replacement after each draw. The total number of marbles is 7 (red) + 9 (white) + 5 (blue) = 21 marbles. If we are to draw two marbles without replacement, the total outcomes reduce by 1 with each draw.

Let's say we want to find the probability of drawing a red marble and then a blue marble. The probability of drawing a red marble on the first draw is 7/21. After drawing a red marble, we are left with 20 total marbles, so the probability of drawing a blue one is 5/20. Therefore, the probability of these two events happening in sequence is calculated by multiplying the separate probabilities: (7/21) * (5/20) = 7/84 ≈ 0.083.

Answer:14

Step-by-step explanation: 4+10=14

Answer: 4 + 10 = 14. So, the answer is 14 cats

Answer:

(x,y)= (-3,1)

Step-by-step explanation:

4x + 9y = -3  => eq(i)

8x + 12y = 12  => eq(ii)

We need to solve these equations to find the values of x and y.

Multiply eq (i) with 2 and then subtract both equations

8x + 18y = -6  

8x + 12y = 12

-     -          -

__________

6y = -18

y= -18/6

y = -3

Putting value of y in eq(i)

4x + 9y = -3

x = -3

4(-3) + 9y = -3

-12 + 9y = -3

9y = -3+12

9y= 9

y= 9/9

y = 1

So, the value of x = -3 and y = 1

(x,y)= (-3,1)

First you should simplify the inequality and get n by itself:

3n - 10 ≥ 2      Add 10 on both sides

3n ≥ 12       Divide 3 on both sides

n ≥ 4

When the sign is ≤ or ≥ (less/greater than or equal to), the line is a solid line.

When the sign is < or >, the line is a dotted line.

If the variable is > than the function (like y > 3x + 2, or x > 2y²) The shaded area is above the line (or going in the positive direction)

If the variable is < than the function (like x < 2, or x < 5z - 7), The shaded area is below the line.

Since we got n ≥ 4,

If n is an x value, or n = x, you would have a horizontal line at y = 4, but if n is a y value, n = y, you would have a vertical line at x = 4. The shaded area should be above the line, or to the right of the line since n is > 4. (Sorry, I don't know if n = y or n = x, hope this clarified things)

Answer:

n ≥4

Step-by-step explanation:

3n -10 ≥ 2

Add 10 to each side

3n -10+10 ≥ 2+10

3n ≥12

Answer:

k=(-7y+11)/4

Step-by-step explanation:

Given

11(k-1)= 7(k-y)

In order to find the value of K we have to separate k on one side, so

Multiplying 11 and 7 into the brackets on both sides

11k-11=7k-7y

Subtracting 7k on both sides

11k-11-7k=7k-7y-7k

11k-7k-11= -7y

Adding 11 to both sides

4k-11+11= -7y+11

4k= -7y+11

4k=-7y+11

k=(-7y+11)/4

So the value of K is (-7y+11)/4.

Answer:

P(green) = ⇒ 5/14

P(red) = ⇒ 2/14

P(green and red) = ⇒ 5/98

The probabilities are P(green) = [tex]\frac{5}{14}[/tex], P(red) = [tex]\frac{1}{7}[/tex] and P(green and red) = [tex]\frac{5}{98}[/tex].

The probability of an event is calculated as the number of favorable outcomes divided by the total number of outcomes.

In this case, Deepak is choosing two marbles one after the other with replacement, which means after drawing the first marble, he puts it back into the bag before drawing the second one.

Since these are independent events (drawing the first marble does not affect the probability of drawing the second), the probability of both events happening is the product of their individual probabilities.

So, the probability that Deepak will choose one green marble and then one red marble is [tex]\frac{5}{14} *\frac{1}{7} =\frac{5}{98}[/tex].

Complete Question:

A bag contains fourteen marbles. There are 4 purple marbles, 3 blue marbles, 5 green marbles, and 2 red marbles. Deepak randomly chooses two marbles from the bag, one at a time, and replaces the marble after each choice. What is the probability he will choose one green marble and then one red marble? Express the probabilities in fraction form.

The cost of the unfurnished and furnished apartments for 1 year would be $8,650 and $9,880 respectively. Therefore, the unfurnished apartment is the better deal for Jonathan.

The cost for the unfurnished apartment for one year would be $600 (monthly rent) * 12 (months) + $600 (one month deposit) + $350 (security deposit) + $850 (furniture cost) = $8,650.

The cost for the furnished apartment for one year would be $190 (rent per week) * 52 (weeks in a year) = $9,880.

Answer:  I and II.

Step-by-step explanation:

By definition, two solids are similar if their corresponding sides are in the same ratio.

Knowing this, let's find which solids are similar:

Corresponding sides ratio of solids I and II:

[tex]\frac{3}{2}=\frac{2}{\frac{4}{3}}=\frac{5}{\frac{10}{3}}[/tex]

[tex]\frac{3}{2}=\frac{3}{2}=\frac{3}{2}[/tex]

Corresponding sides ratio of solids I and III:

[tex]\frac{3}{\frac{9}{2}}=\frac{2}{3}=\frac{5}{8}[/tex]

[tex]\frac{2}{3}=\frac{2}{3}=\frac{5}{8}[/tex]

Corresponding sides ratio of solids II and III:

[tex]\frac{2}{\frac{9}{2}}=\frac{\frac{4}{3}}{3}}=\frac{\frac{10}{3}}{8}}[/tex]

[tex]\frac{4}{9}=\frac{4}{9}=\frac{5}{12}[/tex]

 You can observe that the solids  I and II are similar.

To find the length of line AB, the distance formula √((x2 - x1)² + (y2 - y1)²) is used, with coordinates substituted. The calculated distance is approximately 13.6 units.

To calculate the length of the line AB, we use the distance formula which is derived from the Pythagorean theorem. The formula is:

d = √((x2 - x1)² + (y2 - y1)²)

Here, (x1, y1) are the coordinates of point A and (x2, y2) are the coordinates of point B.

Now, let's substitute the given coordinates into the distance formula:

d = √((7 - (-4))² + (-2 - 6)²)

d = √((7 + 4)² + (-8)²)

d = √(11² + (-8)²)

d = √(121 + 64)

d = √185

d ≈ 13.6

The length of the line AB is approximately 13.6 units.

Final answer:

The equation can then be solved to find the value of 'm', representing the minutes of talk time. In this case, the answer is 68 minutes of talk time each month.

Explanation:

To find the minutes of talk time you use each month, we can set up an equation based on the given information. Let's assume that the number of minutes of talk time you use each month is represented by 'm'.

The total cost for all 6 months is $195.12, which is equal to the sum of the monthly costs. Each month, the cost of the cell phone plan is $23.70 for 700 minutes of talk time, plus an additional $0.06 per minute for each minute over 700 minutes. Additionally, to get email access, it costs 20% of the price for 700 minutes of talk time.

Based on this information, the equation is: 195.12 = 6(0.06m + 23.70 + 0.20(23.70))

To solve the equation, we can simplify it: 195.12 = 6(0.06m + 23.70 + 4.74)

195.12 = 6(0.06m + 28.44)

Divide both sides of the equation by 6, we get: 32.52 = 0.06m + 28.44

Subtract 28.44 from both sides of the equation, we get: 32.52 - 28.44 = 0.06m

4.08 = 0.06m

Divide both sides of the equation by 0.06, we get: m = 68

Therefore, you use 68 minutes of talk time each month.

Final answer:

After setting up the equation based on the total cost for 6 months, we calculate that the user talks for a total of 768 minutes each month. This includes the 700 minutes in the plan and an additional 68 minutes of talk time.

Explanation:

To solve for the number of minutes of talk time used each month, we first set up an equation based on the information given. The total cost for 6 months is $195.12 which includes the monthly plan cost, the additional cost per minute after 700 minutes, and the email cost which is 20% of the 700 minutes talk time plan.

The equation, therefore, is 195.12 = 6(0.06m + 23.70 + 0.20(23.70)), where m is the number of minutes used over 700. Let's solve the equation step-by-step:

Therefore, you use 68 minutes over the 700 included minutes, which means you use a total of 700 + 68 = 768 minutes of talk time each month.

To solve this problem, we find the side length of the square pool, find the inner perimeter of the sidewalk, and then calculate the difference between the outer and inner perimeters. The width of the sidewalk is 5 feet.

This is a Mathematics problem that involves some knowledge of geometry. Firstly, let's inspect the given information: The square swimming pool’s area is 225 square feet. Since the pool is square, the side length of the pool can be found by taking the square root of the area: √225 = 15 feet. So, the inside perimeter of the sidewalk is 60 feet (4*15).

However, the outside perimeter of the sidewalk is 80 feet. The difference between the outside and the inside perimeter (80 – 60) is 20. That value is twice the width of the sidewalk because the sidewalk extends around all four sides. Therefore, each side of the sidewalk must cover extra 5 feet (20 / 4). So, the width of the sidewalk is 5 feet.

4x - y = -6 ....(1)

5x + y = -21 ....(2)

(1) + (2)

9x = -27

x = -3

from (1)

4 * -3 - y = -6

we solve

y = -6

so the answer is

D ( - 3 , - 6 )

The solution to the system of equations is (-3, 6), which corresponds to option D, by using the elimination method to first find x = -3 and then substituting it back to find y = 6.So,option D is correct.

To solve the system of equations using addition (also known as the elimination method), we start with the two given equations:

4x - y = -6

5x + y = -21

Adding these equations together allows us to eliminate the y variable:

4x - y + 5x + y = -6 - 21

Combining like terms, we get:

9x = -27

Dividing by 9 to solve for x:

x = -3

Next, we substitute x = -3 into one of the original equations to solve for y. Using the first equation:

4(-3) - y = -6

-12 - y = -6

y = -6 + 12

y = 6

The solution of the system is the pair (-3, 6), which corresponds to option D.

As a quick check, we can substitute x = -3 and y = 6 into both original equations to ensure they satisfy both equations. Doing this confirms that the solution is correct.

Step-by-step explanation:

the sum of any two sides is bigger than the third side... so 5+9= 14, bigger than 6. 5+6=11, greater than 9. 9+6=15, bigger than 5.

Answer:

B

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

So, let's test each of the points:

A) We have the points: 4, 8, 2. If we sum 4 and 2, the result is 6. Which is not greater than the third side which is 8. So it does not qualify for a triangle.

B) We have the points 5, 9, 6. If we sum 5+6 = 11 which is greater than 9. The sum of any two sides from this set is greater than the third side. It could create a triangle.

C) We have the points 6, 8, 16. If we sum  6+8 = 14 which is not greater than the third side 16. So it could not create a triangle.

D) we have the points 10, 4, 3. If we sum 4+3 = 7 which is not greater than 10. For that reason, it could not create a triangle.
