larisa [96]

Step-by-step explanation:

We dimension of the smallest cube to be made from cuboids of sides 3 m , 4 m and 5 m will be the least common multiple of 3 m, 4 m and 5 m i.e. 60 m

12 cuboidal should be stacked along 5 m edge to 60 m, 15 cuboids should be stacked along 4 m edge and 20. cuboids should be stacked along edge to make a cube of 60 m edge, Hence number of cuboids are 12× 15 ×20=3600

hope it helps

How do I find x and y
Usimov [2.4K]
First you would have to find the third angle in the triangle which you would do by adding 63+61 and subtracting the resulting number from the total degrees in a triangle. From there, you would calculate x and y using the knowledge that angles on a line equal 180.

3y - 5x = 9<br> Y= -5/3x-12<br> Are the parallel
bija089 [108]

Answer:

Both lines are not parallel

Step-by-step explanation:

Given as :

Two lines equation are as :

3y - 5x = 9   And  y = - \frac{5}{3}x - 12

First line is now written in eq y = mx + c

Or,    3y = 5x + 9

Or,      y = \frac{5}{3}x +  \frac{9}{3}

So, Slop of this line ( m 1 ) =  \frac{5}{3}

     slop of second line ( m 2) is  \frac{- 5}{3}

∵ The slop of both lines are not equal , so the line are not parallel to each other .

Hence Both lines are not parallel     Answer
