Jess made 3 different stacks of wooden blocks The first stack was 7 blocks high the second stack was 3 blocks higher than the first and the the final stack was 7 blocks higher than the second In the total how many blocks did Jess use for all 3 stacks

Jess used 34 blocks

Step-by-step explanation:

the first stack =7

second stack =7+3=10

third stack =10+7=17

total: 7+10+17=34

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
