One pipe can empty a tank in 45 minutes while a second pipe can empty it in 60 minutes. If both pipes are opened at the same tim

Ludmilka [50]

Answer:

It will take 25.7 minutes when they are working together

Step-by-step explanation:

Here, we want to know how long it will take both pipe working together to drain the tank

Let the volume of water to be drained be xL

for the first one, rate is

x/45 L/minutes

for the second x/60 L/minutes

Joint rate will be

x/45 + x/60 = 4x + 3x/180 = 7x/180

Now go get the time involved here, we simply divide the volume by the rate

That would be;

x divided by 7x/180

= x * 180/7x

= 180/7 = 25.7 minutes

Find the volume of the figure 14cm,8cm,10cm,10cm,10cm,8cm pls!

Alexeev081 [22]

Step-by-step explanation:

If all of these are supposed to be a length in a different dimension (a 6d object), then just multiply all of them like you would do in 3d.

14*8*10*10*10*8 = 896000 cm^6

If this is supposed to be a 3d object and all the sides with equal length are just supposed to be going in the same direction, multiply one of each of the lengths.

14*8*10 = 1120 cm^3

You would divide 141 by 3 because there was three sweatshirts bought, so the answer from that would be the price of one.

Estimate how many books can be shelved in a college library with 3500 m2 of floor space. Assume 8 shelves high, having books on

matrenka [14]

Answer:

This college library would hold approximately $6*10^{5}/tex] books.Step-by-step explanation:Having books on both sides, and each book being 25 centimeters (there is 100 cm in a meter, so 25 cm=0.25 m) deep, shelves must be around 50 cm (or 0.5 m) wide.If corridors must be 1,5 m wide, every two linear meters (perpendicular to corridors and shelves) of floor space there is 1.5 m of corridors and 0.5 m of shelves and that sequence repeats itself, i.e. there is 75% (1.5 of every 2 meters) of space occupied by corridors and 25% (0.5 of every 2 meters) occupied by shelves, that is:[tex]Floor space_{shelves}=Total floor space*proportion of shelves=3500m^{2} *0.25=875m^{2}$

Knowing that every square meter of floor space occupied by shelves is in reality eight (because of being 8 shelves high) square meters of shelve space where to put books and that the average area of a book is

$Area occupied=depth*width=0.25m*0.05m=0,0125m^{2} per book$

Having all the necessary data, we estimate how many books would this college library hold:

$Books=\frac{Shelve space}{area_{book} } =\frac{875m^{2}*8 }{0.0125\frac{m^{2} }{book} } =560000 books$

As it is an estimate, we round it up to the nearest hundred-thousand, i.e., approximately [tex]6*10^{5}/tex] books can be shelved on this library
