A sample of a radioactive element has a mass of 80 g. How much daughter materials are in the sample after two half-lives?

Answers

Answer:

60g

Step-by-step explanation:

A sample of radioactive element has a mass that weighs 80g

The amount of life spent is two half-lives

This means that after two half lives, the number of daughter materials that would be available in the sample is 60g

Hence 60g of daughter cells would be available after two half lives

Simplify: 10x+2x-3= 9
A. x=-1
B. x=-2
C. x=1
D. x=2

Answers

Answer:

C. x = 1

Step-by-step explanation:

Combine like terms

10 + 2 − 3 = 9

12 − 3 = 9

Add 3 to both sides of the equation

12 − 3 + 3 = 9 + 3

Add the numbers

12 = 9 + 3

12 = 12

[tex]\frac{12x}{12} = \frac{12}{12}[/tex]

Cancel terms that are in both the numerator and denominator

[tex]x = \frac{12}{12}[/tex]

Divide the numbers

x = 1

Therefore the correct answer is C. x = 1

Answer:

C. x = 1

Answer:

Scale factor  = 3

Step-by-step explanation:

Using similar triangles

AT/AG = AB/AC

9/3 = x+10/3x-10

Cross multiply

3(x+10) = 9(3x-10)

Expand

3x+30 = 27x-90

3x-27x = -90 - 30

-24x = -120

x = 120/24

x = 5

For the larger triangle;

AC = 3x-10

AC = 3(5)-10

AC =15-10

AC = 5

AB = x+10

AB = 5+10

AB = 15

For the scale factor;

Since AT/AG = AB/AC

9/15 = 3/5

3*3/5*3 =3/5

Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3

bags can each shelf hold?
Time
elapsed

Answers

Answer:

50 bags of sugar

Step-by-step explanation:

There are 1000 grams in 1 kilogram

We know each shelf can hold up to 30 kilograms and we know each bag of sugar weighs 600 grams.

We multiply 30 kilograms (kg) by 1000 to make it equal to grams so:

30 kg x 1000 = 30,000 grams

We should divide 30,000 by 600 to know how many bags each shelf can hold

30,000/600 = 50 bags of sugar

[tex]\sqrt{125}[/tex]

Step-by-step explanation:

Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]

225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]

Answer:

x = 5[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

x² + 10² = 15²

x² + 100 = 225 ( subtract 100 from both sides )

x² = 125 ( take the square root of both sides )

x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form
