The diagram below shows the contents of a jar from which you select marbles at random.

An illustration of a jar of marbles is shown. Four of the marbles are labeled with an upper R, seven of the marbles are labeled with an upper B, and five of the marbles are labeled with an upper G. The key identifies upper R to represent red marbles, upper B to represent blue marbles, and upper G to represent green marbles.

What is the probability of selecting a red marble, replacing it, and then selecting a blue marble? Show your work.

Answer:

The smallest number is 7

Step-by-step explanation:

Using simultaneous equation;

x+y = 18.....(1)

4x-y = 17.....(2)

from equation (1)..

x+y = 18

y = 18-x...(3)

substitute y into equation (2)

4x-y = 17

4x-(18-x) = 17

4x-18+x = 17

4x+x = 17+18

5x = 35

x = 35÷5

x = 7

substitute x into equation (3)

y = 18-x

y = 18-7

y = 11

Therefore; x=7

y=11

11+7=18

(4×7)-11=17

the smallest number is 7

Answer:

9.5 seconds

Step-by-step explanation:

0-4 seconds => 20 meters

4-9.5 seconds => 55 meters

total = 75 meters

A horse run a distance of 75 metres in 9.5 seconds.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time.

Here, From the graph,

when, t = 4 sec.

    distance = 4 X 10 X 1/2

                    = 20 meters

Now, 75 - 20 = 55 meters

So, 55/10 = 5.5 seconds

Total time = 5.5 + 4

                 = 9.5 sec.

A horse run a distance of 75 metres in 9.5 seconds.

Thus, A horse run a distance of 75 metres in 9.5 seconds.

Answer:

66mm

Step-by-step explanation:

A diagram of a coin is shown.

Radius = 10.5 mm

The approximate circumference of the coin is calculated using the formula

2πr

Use 3.14 as an estimate for it.

r = 10.5mm

Hence:

2 × 3.14 × 10.5

= 65.94

Approximately = 66mm

O A 21 mm

O B. 33 mm

O c. 66 mm

O D. 84 mm

Answer:

y=0.5x+3

Step-by-step explanation:

So the point of this is to make y the only thing on one side. So first you have to add 6 on both sides. That would make is x+6=2y. Next you need to divide 2 on both sides. That would equal 0.5x+3=y.

Hope this helped!!! :D

The required equation is  [tex]y=0.5x+3[/tex].

Given equation is,

[tex]x=2y-6[/tex]

We have to rearrange the equation in terms of y.

Here, [tex]x=2y-6\\[/tex]

Adding 6 to both sides of the equation,

[tex]x+6=2y-6+6[/tex]

[tex]x+6=2y[/tex]

Now dividing the equation by 2 both sides, we get

[tex]\frac{x+6}{2} =y\\[/tex]

[tex]y=0.5x+3[/tex].

Hence the required equation is [tex]y=0.5x+3[/tex].

Answer:

The first 8 letters of the alphabet are:

{A, B, C, D, E, F, G, H}

To find the number of permutations, we can think of 8 positions. In each one of these positions, we can put one of the letters, now we need to find the number of possible options for each one of these positions, the total number of permutations will be equal to the product between all of these options.

Now, taking one letter at a time (to assign at each position)

For the first position, we have 8 options.

For the second position, we have 7 options (because one letter is already taken)

For the third position, we have 6 options (because two letters are already taken, one in the first position and another in the second)

For the fourth position, we have 5 options.

For the fifth position, we have 4 options.

For the sixth position, we have 3 options.

For the seventh position, we have 2 options.

For the last position, we have 1 option.

Then the total number of permutations is:
