<h3>Answer: 920</h3>

=================================================

Explanation:

The front face is a triangle with area of base*height/2 = 15*8/2 = 60 square feet.

The back face is identical to the front face, so we have another 60 square feet.

The left rectangular wall is 20 ft by 8 ft tall. Its area is 20*8 = 160 ft^2

The right slanted rectangular face is 20 ft by 17 ft. Its area is 20*17 = 340 ft^2

Lastly, the bottom rectangle floor is 15 ft by 20 ft to give an area of 15*20 = 300 ft^2

------------------

To summarize so far

Front face = 60 ft^2
Back face = 60 ft^2
Left face = 160 ft^2
Right slanted face = 340 ft^2
Bottom floor = 300 ft^2

Add up those areas to get the overall surface area.

60+60+160+340+300 = 920

I may be wrong but I think the answer should be 920ft squared. Maybe wait for someone else to confirm this. Good luck!

The sum of the reciprocals of two consecutive odd integers is 24/143. find the two integers.

nordsb [41]

Let one integer be x, the consecutive odd integer is x+2
reciprocals are 1/x and 1/(x+2)
1/x +1/(x+2)=24/143
make the denominators the same:
(x+2)/[x(x+2)] +x/[x(x+2)]=24/143
143(2x+2)=24(x)(x+2)
286x+286=24x²+48x
24x²-238x-286=0
use the quadratic formula: x=22 this doesn't work because 22 is not an odd number.
or x=-2.1666666666 (this is not an integer)

weird.

A number sentence is shown below:

d1i1m1o1n [39]

Number sentence is simply a sentence, that uses numbers and arithmetic signs.

The context that can be created from the sentence is: How many bits are there, in $32\frac 14$ bytes
The verbal meaning of $32\frac 14 \div \frac 18 = 258$ is: When $32\frac 14$ is divided by $\frac 18$ , the result is $258$
