You can write it like this:
20/1 * 3/5

And then you can multiply to get this:
60/5

And then you can determine how many 5 go in 60 to figure out the exact number which is 12!

I hope that helps! Feel free to let me know if you have any questions! :3

△ABC is a right triangle with right angle at ∠B .

GuDViN [60]

We can use the tangent function to find the value of angle C.

tan ∠C = 29/38
tan ∠C = 0.76315789473

Now we will do inverse of tangent on both sides.

∠C ≈ 37°

Hope this helps :)

Answer:

Step-by-step explanation:

$\frac{-5+2 \iota}{1+7 \iota} \times \frac{1-7 \iota}{1-7 \iota} \\=\frac{-5+35 \iota+2 \iota-14 \iota^2}{1-49 \iota^2} \\=\frac{-5+37 \iota-14(-1)}{1-49(-1)} \\=\frac{9+37 \iota}{50} \\=\frac{9}{50} +\frac{37}{50} \iota$

7. Find a conversion factor between cubic meters and cubic

RUDIKE [14]

Step-by-step explanation:

We know that,

1 m = 100 cm

the conversion from m² to cm² is as follows :

(1 m)² = (100 cm)² = 10000 cm²

A conversion factor between cubic meters and cubic centimeters is as follows :

(1 cm)³ = (100 cm)³

= 1000000 cm³

To convert m³ to cm³, multiply by 1000000.

Hence, this is the required solution.

Situation: A 25 gram sample of a substance thats used for to sterilize surgircal instruments has a k-value of 0.1205. N=Noe^-kt

Naya [18.7K]

Going by the formula, Half-Life = ln(.5) / k
Half-Life = .693147 / .1205
Half-Life = 5.75 days and rounded to nearest tenth,
Half-Life = 5.8 days
