Answer:

we have.

11x=½(16x+16+50)

22x=16x+66

22x-16x=66

6x=66

x=66/6

x=11

118°=½(6x-11+181)

236=6x+170

6x=236-170

x=66/6

x=11°

34°=½(arcAK-arc LN)

34×2=(110-arc LN)

arc LN =110-68

arc LN=42°

<L=½(arc EN-arc KM)

<L=½(139°-73°)

<L=33

4/5=27/x using two different methods. Explain each method

Andrei [34K]

Metathod 1
4/5=27/x
mutiply 4/5 by 27/27 and multily 27/x by 4/4
108/135=108/4x
therefor
108:135=108:4x
therefor
135=4x
divide by 4
33.75=x

metahod 2

4/5=27/x
multiply oht sides by x
4/5x=27
multiply both sides by 5/4 to clear fraction
x=135/4
x=33.75

Given the conversion factor which cube has the larger surface area?

Eduardwww [97]

Given the surface area of a cube as

$\begin{gathered} SA=6l^2 \\ \text{where l is the length} \end{gathered}$

Given Cubes A and B

$\begin{gathered} \text{Cube A} \\ l=19.5ft \end{gathered}$ $\begin{gathered} \text{Cube B } \\ l=6m\text{ } \\ \text{ in ft}\Rightarrow\text{ 1m =3.28ft} \\ l=6\times3.28ft=19.68ft \end{gathered}$

Find the surface area of the cubes and compare them to know which one is larger

$\begin{gathered} \text{Cube A} \\ SA=6\times19.5^2=6\times380.25=2281.5ft^2 \end{gathered}$ $\begin{gathered} \text{Cube B} \\ SA=6\times19.68^2=6\times387.3024=2323.8144ft^2 \end{gathered}$

Hence, from the surface area gotten above, Cube B has a larger surface area than Cube A
