Answer:

4/7.

Step-by-step explanation:

This the question in which marbles have to be taken out of a bag. Odds in another word for probability.

Total number of marbles in the bag = 2 Blue + 1 Green + 4 Red = 7 marbles.

Required marbles = 3 red marbles.

Therefore:

P (a red marble is selected in the first attempt) = Red Marbles / Total Marbles.

P (a red marble is selected in the first attempt) = 4/7.

Therefore, the correct answer is 4/7!!!

Find the measure of line KM.<br> A. 14<br> B. 9<br> C. 12<br> D. 10

HACTEHA [7]

$\\ \sf\longmapsto \dfrac{3}{x-4}=\dfrac{6}{x-5}$

$\\ \sf\longmapsto 3(x-5)=6(x-4)$

$\\ \sf\longmapsto 3x-15=6x-24$

$\\ \sf\longmapsto 3x-6x=-24+15$

$\\ \sf\longmapsto -3x=-9$

$\\ \sf\longmapsto x=\dfrac{-9}{-3}$

$\\ \sf\longmapsto x=3$

$\\ \sf\longmapsto KM=3+6=9$

A rectangular prism measures 225 inches by 315 inches by 2 inch.

Bas_tet [7]

Answer:

No I don't agree with Priya

The reason why I don't agree with Priya is because 25 Inch side blocks are BIGGER than 15 inch side blocks. That means that it will take less amount of 25 inch side blocks to fill up the volume of the rectangular prism rather than 15 inch side blocks.

(I'm sorry, I don't know what was your previous question, so I can't answer that part. If you comment it below, I will do it!)
