No, because the sum of two sides must be larger than the third.

assume the substance has a half-life of 11 years and the initial amount is 126 grams.How long will it be until only 15 % remains
Mumz [18]
(126) times (1/2 to the x/11 power) = 15% times 126

(1/2) to the x/11 power = 0.15

Take the log of both sides :

(x/11) times log(1/2) = log(0.15)

Multiply both sides by 11 :

'x' times log(1/2) = 11 x log(0.15)

Divide both sides by " log(1/2) " :

x = 11 x log(0.15)/log(1/2) = <em><u>30.107 years</u></em> (rounded)

That's the time it takes for <em><u>any-size</u></em> sample of this substance
to decay to 15% of its original size.

The circumference of a circle is about 37.7 cm and the diameter is about 12 cm. What expression best represents the value of π ?
Yakvenalex [24]

Answer:

Step-by-step explanation:

Circumference of a circle means the perimeter of a circle and it is given be

Perimeter=2πr

P=2πr

Though π is a constant

But this question want us to find π

Make π the subject of the formula

Then, divide both side by

π=P/2r

Given that P=37.7cm

And diameter =12

And radius is half of diameter.

Therefore, radius =12/2=6cm

Then

π=P/2r

π=37.7/2×6

π=37.7/12.

Then, the last option is the correct option
