Answer:

43.638 cubic meters

Step-by-step explanation:

The triangular prism has 5 faces - 3 rectangular and 2 congruent triangular. Calculate the area of each face then add them together to find the surface area.

The triangles are 5.3 by 1.26 so the area of the two is 6.678.

The largest rectangle face is 5.3 by 3.3 so the area is 5.3*3.3 = 17.49.

The side rectangle face that is 3.3 by 3.6 so the area is 3.3*3.6 = 11.88.

The side rectangle face that is 2.3 by 3.3 so the area is 2.3*3.3 = 7.59.

Add all the areas together.

6.678 + 17.49 + 11.88 + 7.59 = 43. 638

Solving equations <br><br> 3(2x-1)=6
Lubov Fominskaja [6]

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

distribute 3 to the 2x and -1 by multiplying

6x - 3 = 6

add 3 to both sides to get 6x by itself and it keeps both sides equal

6x = 9

divide by 6

x = 9/6 = 3/2

x = 3/2

A manager forecasts that 150 guests will be served tomorrow. The manager knows that one server can provide high quality service
iVinArrow [24]

Answer:

5 servers and 3 cooks(since a person doesn't exist in fraction)

Step-by-step explanation:

From the question provided above, the manager(who is obviously organizing some kind of party or get-togethers) is expecting a hindered and fifty guests in total .

And it also says that if a server can handle 30 guests and 150,how many of them are need?

Let X be number of servers needed:

X= 150/30 = 5 servers

AND

If a single cook can prepare meals for 60 guests,the number of cooks required to cover for 150 guest will be:

X= 150/60 = 2.5,but since a fraction of a human doesn't exist, we have to say that the manager needs 3 cooks(2 of them will handle a total of 120 guests and the other cook handles the 30 guests)
