Answer:

3 nights

Step-by-step explanation:

let n equal the number of nights

6 = 2n ---> 6 cm = 2 cm x the number of nights

6/2 = 2n/2 ---> divide both sides of the equation to isolate n

3 = n ---> number of nights equals 3

6 is the number of centimeters needed divided by 2 the number of centimeters per night which would give you the number of nights.

r = 2 inches

total h of the cylinder = 6+6+6 = 18 inches

$SA = 2\pi {r}^{2} + 2\pi \: rh$

$= 2\pi \: r(r + h)$

$= 2 \times 3.14 \times 2(2 + 18)$

$= 2 \times 3.14 \times 2 \times 20$

$= 251.2square \: inches$

NEED HELP ASAPInstructions: Find the length of the missing sides. Round your answers to the

Pie

Answer:

$x = 9.4$

$y = 17.7$

Step-by-step explanation:

Given: The figure

Required: Find x and y

The relationship between length x, length 15 and angle 32 is as follows:

$tan \theta = \frac{opp}{adj}$

So, we have:

$tan\ 32= \frac{x}{15}$

Cross multiply:

$x =15*tan\ 32$

$x = 15 * 0.6248693519$

$x = 9.3730402785$

$x = 9.4$ --- approximated

Similarly:

The relationship between length y, length 15 and angle 32 is as follows:

$cos \theta = \frac{adj}{hyp}$

So, we have:

$cos\ 32= \frac{15}{y}$

Cross Multiply:

$y * cos\ 32= 15$

Solve for y

$y = \frac{15}{cos\ 32}$

$y = \frac{15}{0.84804809615}$

$y = 17.6876760506$

$y = 17.7$ --- approximated

A vessel has 4 liters and 500 ml of curd. In how many glasses, each of 25 ml capacity, can it be filled?

dalvyx [7]

Step-by-step explanation:

easy to look up : mili stands for 1/1000

so,

500 ml are 500/1000 liters.

25 ml are 25/1000 liters (a tiny glass).

and 1 Iiter is of course, 1000/1000 liters (1000 ml).

4 liters 500 ml are then

4×1000/1000 + 500/1000 = 4500/1000 l = 4500 ml.

how many glasses of 25 ml can be filled with that ?

this is the same question as into how many parts of 25 can 4500 be split ? or, how often does 25 fit into 4500 ?

all this is done by division :

4500 / 25 = 180

so, 180 of such glasses can be filled.
