7, you divide the 14 by 2 because the qr is two times the length of gh, therefore 7 is two times the length of fh

Answer:

7cm

Step-by-step explanation:

See since 10 shrunk to 5

And it is the same shape but smaller, each side must be divided by 2 and 14/2 is 7

That's my reasoning for this

Rewrite the expression x^3+10x^2+13x+39/x^2+2x+1 in the form of q(x)+r(x)/b(x)

natima [27]

$\dfrac{x^3+10x^2+13x+39}{x^2+2x+1}$

$x^3=x\cdot x^2$ , and $x(x^2+2x+1)=x^3+2x^2+x$ . Subtracting this from the numerator gives a remainder of

$(x^3+10x^2+13x+39)-(x^3+2x^2+x)=8x^2+12x+39$

$8x^2=8\cdot x^2$ , and $8(x^2+2x+1)=8x^2+16x+8$ . Subtracting this from the previous remainder gives a new remainder of

$(8x^2+12x+39)-(8x^2+16x+8)=-4x+31$

$-84x$ is not a multiple of $x^2$ , so we're done. Then

$\dfrac{x^3+10x^2+13x+39}{x^2+2x+1}=x+8+\dfrac{-4x+31}{x^2+2x+1}$

A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.

Triss [41]

Answer:

650 kg/m³

Step-by-step explanation:

The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.

density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³

= 650 kg/m³

Hope this answer helps you :)

A water well rig has dug to a height of -60 feet after one full day of continuous use. if the rig has been running and is curren

Romashka [77]

Given :

A water well rig has dug to a height , H = 60 feet after one full day of continuous use .

To Find :

If the height is currently 143.6 feet how time it been running .

Solution :

It is given that height after 24 hours of use is 60 feet .

So , height loose in 1 hours is :

$h=\dfrac{60}{24}\ feet\\\\h=2.5 \ feet$

Now , time taken to cover a height of 143.6 feet is :

$t = \dfrac{143.6}{2.5}\ hours\\\\t=57.44\ hours$

Therefore , time taken is 57.44 hours .

Hence , this is the required solution .
