$10^{12}$ means 1 followed by 12 zeros, which is 1 trillion.

$10^{-8} = 0.00000001$ which is a lot smaller.

So the biggest number is the first one,

Answer:

Sipho is 10 years old.

Litha is 19 years old.

Step-by-step explanation:

We will use variables as their age.

x for Sipho

y for Litha

Here's what we know:

$x + y= 29$

$6 + x = y - 3$

Now we just need to isolate a variable in order to begin a system of equation.

$6 + x = y - 3 \\ + 3 \\ 9 + x = y$

Now that we have y in terms of x we just need to plug in

$x + y = 29 \\ x + (9 + x) = 29 \\ x + 9 + x = 29 \\ 2x + 9 = 29 \\ - 9 \\ 2x = 20 \\ \div 2 \\ x = 10$

Now that we know x we now must find y.

$x + y = 29 \\ (10) + y = 29 \\ 10 + y = 29 \\ - 10 \\ y = 19$

We are done! Sipho is 10 years old and Litha is 19 years old.

Answer:

$\large\boxed{P=5\dfrac{3}{10}\ cm=5.3\ cm}$

Step-by-step explanation:

If you want find the perimeter, then you must add all lengths of sides of the given polygon.

$P=AB+BC+CD+DE+EA\\\\AB=1\dfrac{3}{4}\ cm,\ BC=1\dfrac{1}{10}\ cm,\ AE+DC=1\dfrac{1}{5}\ cm,\ DE=1\dfrac{1}{4}\ cm\\\\P=1\dfrac{3}{4}+1\dfrac{1}{10}+1\dfrac{1}{5}+1\dfrac{1}{4}=\left(1\dfrac{3}{4}+1\dfrac{1}{4}\right)+1\dfrac{1}{10}+1\dfrac{1\cdot2}{5\cdot2}\\\\=2\dfrac{4}{4}+1\dfrac{1}{10}+1\dfrac{2}{10}=3+2\dfrac{3}{10}=5\dfrac{3}{10}$

Other method.

Convert the mixed numbers to the decimal:

$AB=1\dfrac{3}{4}\ cm=1.75\ cm\\\\BC=1\dfrac{1}{10}\ cm=1.1\ cm\\\\AE+DC=1\dfrac{1}{5}\ cm=1.2\ cm\\\\DE=1\dfrac{1}{4}\ cm=1.25\ cm\\\\P=1.75+1.1+1.2+1.25=5.3\ cm$
