Answer:

The volume of the prism is of 1368 cubic m.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism is the multiplication of the lengths of its dimensions.

In this question:

Dimensions of 8m, 9m and 19m. So

8*9*19 = 1368.

Dimensions in meters, so volume in cubic meters.

The volume of the prism is of 1368 cubic m.

uranmaximum [27]

Answer:

It'd be 4/15

Step-by-step explanation:

The total marbles is 6, so for black it's 4/6, but it's not being put back in so for the next one, the denominator would be 5. For green it's 2/5

4/6 times 2/5 equal 4/15

Hope this helps!

I really need help bad!!

Answer:

5. x = 17

7. x = 2

Step-by-step explanation:

The applicable relation is, "the product of the near distance to the circle and the far distance to the circle is the same for each secant." Distance is measured from the point where the secants intersect.

Using the rule, we have ...

7(7+x) = 8(8+13)

7+x = 24 . . . . . . . . . divide by 7

x = 17 . . . . . . . . . . subtract 7

The same rule applies.

7(7 +6x -1) = 9(9 +x +3)

42x +42 = 9x +108 . . . . . . simplify

33x = 66 . . . . . . . . . . . . . subtract 9x+42

x = 2 . . . . . . . . . . . . . . divide by 33

Answer:

(22,2) and (18,6)

Step-by-step explanation:

Heyyyy so the equation is y=24-x

So let's do 24-x to get y

24-18=6

Same thing

24-22=2

I also did this on Khan so yeah its right :D

denpristay [2]

Answer:

total number of distinct combination is 82

Step-by-step explanation:

Given data:

green marbles 3

red marbles = 2

number of distinct colors is 5

different cases of combination of 5 marbles is

case -1 when there is 5 distinct color marble - $^7C_5 = 21$

case - 2 when there is 3 different color and two are of same color $^6C3_ \times 2 = 30$

case 3 - when 2 are of different type and 3 are of same color $= ^6C2_ = 15$

case 4 - when 1 are of different color and 2 are of different color $=^5C1_ \times \frac{4!}{2! 2!} = 15$

case 5 when three are of same type and 2 are of different color = 1

total number of distinct combination is 82
