The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.
The answer is A. :). Have a great day!
Answer:
Strawberry > Rasberry
6.18 > 6.1
Step-by-step explanation:
Data provided in the question
Strawberry = 6.18 pound
Raspberry = 6.1 pound
Based on the above information
As we can derive that the number of pounds in strawberry is greater than the number of pounds in Rasberry
So, equality would be represented as a
a. Strawberry > Rasberry
6.18 > 6.1
Therefore we use the greater sign to show the inequality
Answer:
yes
Step-by-step explanation:

The value of 5.7 x 10⁸ is 570,000,000 CHOICE C.
The value of 8⁴ is 8 * 8 * 8 * 8 = 4,096 CHOICE C.
Prime factorization of 1,260
1260 ÷ 2 = 630
630 ÷ 2 = 315
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
2 x 2 x 3 x 3 x 5 x 7 CHOICE D.
Composite numbers are numbers that have more factors other than 1 and itself.
91 / 1 = 91
91 / 7 = 13 CHOICE C. 91 is a composite number.
