Margarita [4]3 years ago
3 0

Answer: 1. False

2. True

3. True

4.False


Step-by-step explanation:

1. False, because 6 is a multiple of 3 but 6 is not an odd number.

2. True, all even numbers are multiple of 2, and thus divisible by 2. Any number that is divisible by 2 must be a multiple of 2. hence,the given biconditional statement in true.

3. True, all multiples of 5 has 0 or 5 in the ones place.

Thus the given biconditional statement is true.

4.False, because 6 is not a multiple of 4 but 6 is not a prime number.

The radioactive isotope radium has a half-life of 1,600 years. The mass of a 100-gram sample of radium will be______ grams after
Olenka [21]
To solve this we are going to use the half life equation N(t)=N_{0} e^{( \frac{-0.693t}{t _{1/2} }) }
Where:
N_{0} is the initial sample
t is the time in years
t_{1/2} is the half life of the substance
N(t) is the remainder quantity after t years 

From the problem we know that:
N_{0} =100
t=200
t_{1/2} =1600

Lets replace those values in our equation to find N(t):
N(200) =100e^{( \frac{(-0.693)(200)}{1600}) }
N(200)=100e^{( \frac{-138.6}{1600} )}
N(200)=100e^{-0.086625}
N(200)=91.7

We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be 91.7 grams.

If the circumference of a circle is 24, and the angle measure of an arc is 120°, which is the length of the arc?
kupik [55]
<span>Using radian meansure
theta = (arc length)/radius
---
arc length = radius*theta
----
Your Problem:
120 degrees = 120(pi/180) = (2/3)pi radians

----
circumference = 2pi*r
24 = 2pi*r
r = 12/pi
-------------
arc length = (12/pi)(2/3)pi = 8 units

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!</span>
