A plumber has a 2.5 metre long copper pipe
Anastaziya [24]

We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.

Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.

1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>

We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.

250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left

An elevator containing 3 people can stop at any of the five floors. What is the probability that no two people get off at the sa
olasank [31]

Answer:

48%

Step-by-step explanation:

We have 3 people and 5 floors

We can't have two or more people leaving in the same floor.

So, the first person to leave has 5 possibilities (all 5 floors)

Then, the second person will have only 4 possibilities, as this person can't leave in the same floor as the first one.

Lastly, the third person will have only 3 options (the 3 remaining floors that weren't selected).

The total number of possible choices, without restrictions, is 5 possibilities for each person, so 5*5*5 = 125 combinations

The combinations we want is 5*4*3 = 60 combinations

So the probability of all people choosing different floors is 60/125 = 0.48 = 48%

What is the area of the two-dimensional cross section that is parallel to face ABC ?
Umnica [9.8K]

Answer:

The area of the two-dimensional cross section is 30\ ft^{2}

Step-by-step explanation:

we know that

The two-dimensional cross section that is parallel to face ABC is a triangle congruent with the triangle ABC

Therefore

Calculate the area of triangle ABC

A=\frac{1}{2}(BC)(AB)

we have that

Triangles ABC and DEF are congruent

so

BC=EF=12\ ft

AB=5\ ft

substitute

A=\frac{1}{2}(12)(5)=30\ ft^{2}
