CD has the endpoints C(3, 2) and D(–5, –2). Charlie wants to place the point E at the point that partitions this line segment in

Ganezh [65]

So ... notice the picture below... the ratio is 3:1 from C to D, meaning the segment CE takes 3 units, whilst the ED segment takes 1

anyhow

$\bf \textit{internal division of a line segment}
\\ \quad \\\\
C(3,2)\qquad D(-5,-2)\qquad
ratio1=3\qquad ratio2=1\qquad 3:1
\\\\\\
\cfrac{C\underline{ E }}{\underline{ E }D}=\cfrac{ratio1}{ratio2}\implies 
ratio2\cdot C=ratio1\cdot D
\\\\\\
1(3,2)=3(-5,-2)
\\ \quad \\\\
{{ E=\left(\cfrac{\textit{sum of "x" values}}{ratio1+ratio2}\quad ,\quad \cfrac{\textit{sum of "y" values}}{ratio1+ratio2}\right)}}$

$\bf \qquad thus
\\\\\\
E=\left(\cfrac{(1\cdot 3)+(3\cdot -5)}{3+1}\quad ,\quad \cfrac{(1\cdot 2)+(3\cdot -2)}{3+1}\right)$

Find the surface area of the cylinder to the nearest tenth of a square u it

Rudik [331]

Answer:

Step-by-step explanation:

Surface area of a cylinder = 2 x 3.14 x rh + 2 x 3.14 x r^2

S.A. = (2 x 3.14 x 3 x 18.2) + (2 x 3.14 x 3^2)

S.A. = 399.4cm^2

Alaina measured a boarding school and made a scale drawing. The scale of the drawing was 1 millimeter = 7 meters. In the drawing

alex41 [277]

Answer:

The length of the actual building is 112 meters long.

Step-by-step explanation:

The key words we need to know are these : scale is 1 millimeter = 7 meters, and 16 millimeters long.

The question is asking for the building's actual height.

To solve this, we need to set up a ratio, have the scale being one ratio and the other 16 millimeters over blank. It's going to look like this :

$\frac{1 mm}{7 m}$ = $\frac{16 mm}{x}$

We need to make sure all the units are lined up - the mm parts of the ratio are next to each other.

Now that we have our ratio set up we can cross product to solve for x.

1(x) = 16(7)

x = 112

So x is 112, or the length of the actual building is 112 meters long.

Hope this helps, please mark brainliest if possible. Have a nice day. :)

7:3=8:x is like like 7/3=8/x
so 7x=24
24/7=x
x=~3.43
