Ben rolled a number cube numbered one through six. It landed on an odd number 30 times. What is the probability that it lands on an odd number on the next roll?

Answers

Answer:

1 /2

Step-by-step explanation:

Sample space of number cube : (1, 2, 3, 4, 5, 6)

Odd numbers on cube : (1, 3, 5) = 3 odd numbers

Since each roll of number cube is independent, the number of times it has landed between fire does not matter :

Therefore, probability of landing on a odd number is :

P = required outcome / Total possible outcomes

P = 3 / 6

P = 1/2

If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the frame be?

Answers

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.

what’s the perimeter of a rectangle with 6x+10 as it’s width and 4x+1 as it’s length

Answers

Answer:

the equation will be  2(6x+10+4x+1)

simplified to

12x+20+8x+2

simplified to

20x+22

The perimeter of the rectangle will be 20x+22

Thank you, Hope it helps

Answer: The length of both sides would be 12x+20 and the width of both sides would be 8x+2, so the perimeter of the rectangle would be 20x+22

A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism

Answers

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.

Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.

Answers

Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

You want to surround the perimeter of a garden with 35 stones. You need to place a certain number of large and small stones and every large stone you want to use 4 small stones. Choose the correct equation to find the number of stones for each size

Answers

Answer:

The answer is "x + 4x = 35; 7 large stones and 28 small stones"

Step-by-step explanation:

Please find the complete question in the attached file.

Let

[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]

Users want to use four small stones for each big stone:

[tex]Y = 4x[/tex]

solving the equations system:

[tex]x + y = 35\\\\y = 4x[/tex]

we find:

[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]

During a basketball game, one of the players scores 8 points for her team. If the points she scored represent 20% of the team's total points, as shown below, how many points did the team score during the game?

Answers

Answer:

40points

Step-by-step explanation:

Given data

Let the total points the team scored be x

so that

20% of x= 8 points

let us solve for x

20/100*x= 8

0.2*x= 8

0.2x= 8

Divide both sides by 0.2

x= 8/0.2

x= 40 points

Hence the time scored 40points

Answers

Answer:

The correct approach is Option A (-4).

Step-by-step explanation:

The given values are:

Vertex of the parabola,

(h, k) = (3, 5)

Passing through,

(x, y) = (-1, 6)

As we know,

The equation of parabola is:

⇒  [tex]x=a(y-k)^2+h[/tex]

On substituting the given values in the above equation, we get

⇒  [tex]-1=a(6-5)^2+3[/tex]

⇒  [tex]-1=a+3[/tex]

On substracting "3" from both sides, we get

⇒  [tex]-1-3=a+3-3[/tex]

⇒           [tex]a=-4[/tex] (coefficient of squared term)

Thus the above is the right choice.
