1/2

If ABC ~ DEF then 12/6, 16/8, and 18/9 would equal 2
BUT since we are going from a large triangle to a small triangle, our answer needs to be less then one, making our answer 1/2

Answer:

The answer is 358.01

Step-by-step explanation:

Given:

$3\times 10^{2}+5\times 10^{1}+8\times 10^{0}+1\times \frac{1}{10^{2}}$

Now, to solve first we crack the power notation then multiply and then do the addition:

$3\times 100+5\times 10+8\times 1+1\times \frac{1}{100}$

(The value of $10^{1}$ is 10 and the value of $10^{0}$ is 1.)

$=300+50+8+\frac{1}{100}$

$=300+50+8+0.01$

$=358.01$ .

Therefore, the answer is 358.01 .

Erin is 8 years younger than twice Paula’s age. The sum of their ages is 40. How old is Erin

Lina20 [59]

You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40
