Answer: 57%
Step-by-step explanation:
Davis's monthly expenditure and his monthly salary was 3 : 7.
This means that for every $7 he received, he spent $3 out of it.
The amount he saved is therefore:
= 7 - 3
= $4
For every $7 received, he saved $4.
Percent = 4/7
= 57%
Answer:
(A)The height of each pyramid is One-half h units.
Step-by-step explanation:
Height of the Cube = h units
Volume of the Cube 
If Base of the cube =Base of the square pyramid
Base of the square pyramid = h units
Since Volume of the Cube = Volume of Six Square Pyramids
Then:
Answer:
1) - 2 / (cos x + sinx)^2.
Step-by-step explanation:
1) I assume you want the derivative of (cos x - sin x) / ( cos x + sin x).
y' = (cosx + sinx)( -sinx - cosx) - (cosx - sinx)(-sinx + cosx)
---------------------------------------------------------------------------
(cosx + sinx)^2
= -sinxcosx - cos^2x - sin^2x - sinxcosx - (-sinxcosx+cos^2x+sin^2x-sinxcosx
-------------------------------------------------------------------------------------------------------
(cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= - 2 / (cos x + sinx)^2.
Answer:
$57.8
Step-by-step explanation:
Horseshoe ranch charges $12.95 ranch entrance fee
$14.95 is paid per hour to rent the horse
Therefore since Mary is going to rent the horse for 3 hours then the total amount she will spend can be calculated as follows
= $12.95 + $14.95×3
= $12.95 + $44.85
=$57.8
