the length of a pond is 1700 CM breadth is 14m and height is 1000 CM if a point is half filled calculate the volume of a water i

Andre45 [30]

Answer:

1190 m^3

Step-by-step explanation:

l = 1700 cm = 17 m

b = 14 m

h = 1000 cm = 10 m

Total volume = l × b × h

= 17 × 14× 10

= 2380 m^3

since it is half filled ,

Volume is half , so,

volume of water in pond = 2380 ÷ 2

= 1190 m^3

Use the data set to answer the question. {22,26,28,35,45,63,91} What is the mean absolute deviation (MAD) of the data set? Enter

shtirl [24]

Answer:

mean absolute deviation is 18.85

Step-by-step explanation:

Step 1:-

Given observation values 22,26,28,35,45,63,91

$mean (x ) = \frac{22+26+28+35+45+63+91}{7}$

mean = 44.28≅ 44

Step2:-

The deviations of the respective observations from the mean (x)

That is $x_{i}-x$

22-44, 26-44,28-44,35-44,45-44,63-44,91-44

-22, -18 ,-16 ,-9, 1, 19, 47

Step 3:-

The absolute values of the given data

$x_{i}-x$

modulus of all these values

22,18,16,9.1,19,47

Step 4:-

Mean absolute deviation M.D=∑ $\frac{x_{i} - x }{n}$

$MAD = \frac{22+18+16+9+1+19+47}{7}$

on simplification we get mean absolute deviation is 18.85

A right rectangular prism's edge lengths are 4 1 2 inches, 4 inches, and 3 inches. How many unit cubes with edge lengths of 1 3

fgiga [73]

Question:

A right rectangular prism's edge lengths are $4\frac{1}{2}$ inches, 4 inches, and 3 inches. How many unit cubes with edge lengths of $\frac{1}{3}$ inch can fit inside the prism?

Answer:

1458 cubes with edge lengths of $\frac{1}{3}$ inch can fit inside the prism.

Step-by-step explanation:

Given:

Dimensions of the rectangular prism = $4\frac{1}{2}$ inches, 4 inches, and 3 inches

length of Edge of the cube = $\frac{1}{3}$

To Find:

Number of unit cubes that can fit inside the prism =?

Solution:

Step 1: Finding the volume of the right rectangular prism

Volume of the right Rectangular prism is = $w\times h\times l$

where

w = width of theright Rectangular prism

h = height of the right Rectangular prism

l = lenght of the right Rectangular prism

Substituting the values ,

Volume of the right Rectangular prism is = $4\frac{1}{2}\times4\times 3$

Volume of the right Rectangular prism is = $\frac{9}{2}\times4\times 3$

Volume of the right Rectangular prism is = $4.5\times4\times 3$

Volume of the right Rectangular prism is = 54 $inch^3$

Step 2: Finding the volume of the cube

Volume of the cube = $(edge)^3$

Substituting the values,

Volume of the cube = $( \frac{1}{3})^3$

Volume of the cube = $( \frac{1}{27})$

Step 3: Find the number of cube that can fit in the cube.

Number of cubes = $\frac{\text{volume of the right Rectangular prism}}{\text{Volume of the cube}}$

Number of cubes = $\frac{54}{\frac{1}{27}}$

Number of cubes = $54\times27$

Number of cubes = 1458 cubes
