If a radioactive isotope has a half-life of 6 hours and 12 milligrams is initially present, how much will
be present in 24 hours?
Answer:0.75 milligrams will be present in 24 hours
Step-by-step explanation:
Step 1
The formula for radioactive decay can be written as
N(t)=No (1/2)^(t/t 1/2)
where
No= The amount of the radioactive substance at time=0=milligrams
t 1/2= the half-life= 6 hours
t=24 hours
N(t) = the amount at time t
Step 2--- Solving
N(t)=No (1/2)^(t/t 1/2)
=N(t)=12 x ( 1/2) ^ (24/6)
= 12 x (1/2) ^4
= 12 x 0.0625
= 0.75 milligrams
Could someone create Equations & Explanations based on this question, because I need to solve using substitution and later modify it to create a system of inequalities.
Answer:
3 hours
Step-by-step explanation:
If both the cars are moving in the same direction,
Speed of orange sports car = 60 miles per hour
Since, this car has already moved for 1 hour,
Distance covered by the sports car = speed × time
= 60 × 1
= 60 miles
Speed of the green van = 30 miles per hour
Since, green van has already moved for the duration = 3 hours
Distance covered by the green van = speed × time
= 40 × 3
= 120 miles
Therefore, distance between sports car and green van = 120 - 60
= 60 miles
Relative speed of orange sports car with respect to green van = Speed of sports car - speed of green van
= 60 - 40
= 20 miles per hour
Time taken by the orange sports car to cover 60 miles (Distance between sports car and green van) = [tex]\frac{\text{Distance between the car and van}}{\text{Relative speed of the sports car}}[/tex]
= [tex]\frac{60}{20}[/tex]
= 3 hours
Therefore, orange sports car will take 3 hours to pass the green mini green van.
i need help with number 2.
Answer:
(1)
Step-by-step explanation:
Given
[tex]\frac{2x}{a}[/tex] + b = c ( subtract b from both sides )
[tex]\frac{2x}{a}[/tex] = c - b ( multiply both sides by a to clear the fraction )
2x = a(c - b) ← distribute
2x = ac - ab ( divide both sides by 2 )
x = [tex]\frac{ac-ab}{2}[/tex] → (1)

Solve for W: P=2L + 2W
A. W=P-L
B. W= 1/2P - L
C. W= 1/2 P + L
D. W= 2P - L
Answer:
B
Step-by-step explanation:
[tex]P=2L+2W[/tex]
[tex]P-2L=2W[/tex] (Subtract 2L from both sides of the equation)
[tex]2W=P-2L[/tex] (Symmetric Property of Equality)
[tex]W=\frac{P-2L}{2}[/tex] (Divide both sides of the equation by 2)
[tex]W=\frac{P}{2} -\frac{2L}{2}[/tex] ("Split" the fractions)
[tex]W=\frac{1}{2}P-L[/tex] (Simplify)

What are the next three terms in the sequence? 2, -3, -6, 18, … -108, -1,944, -209,952 -108, 1,944, -209,952 -108, -1,944, 209,952 108, 1,944, 209,952
Answer: -108, -1,944, 209,952
Step-by-step explanation:
The the next term in this sequence is being determined by multiplying the last two numbers of the sequence.
Next three terms are;
= -6 * 18
= -108
= 18 * -108
= -1,944
= -108 * -1,944
= 209,952

Nadine conducted an experiment with four possible outcomes. Trevor conducted the same experiment, but he doubled the number of trials. Which statements are true? Select two options. Trevor has more experimental outcomes than Nadine. Trevor’s sample space is greater than Nadine’s. Trevor’s experimental probability is more likely closer to the theoretical probability than Nadine’s. Nadine’s experimental probability is more likely closer to the theoretical probability than Trevor’s. Nadine has more experimental outcomes than Trevor.
Answer:
A and C
Step-by-step explanation:
Nadine and Trevor both conducted an experiment but Nadine conducted with four possible outcomes and Trevor doubled the trials, therefore, Trevor will have more experimental outcomes than Nadine because he doubled the trials. Moreover, Trevor's experimental probability is more likely closer to theoretical probability than Nadine's, therefore option 'A' and 'C' are correct.
Answer:
Trevor has more experimental outcomes than Nadine.
Trevor’s experimental probability is more likely closer to the theoretical probability than Nadine’s.

What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
1.The triangle is congruent by ASA postulate
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the triangles are congruent.
2. The triangle is congruent by SSS postulate
If all three sides of a triangle are congruent to corresponding three sides of other triangle then the two triangles are congruent.

a road crew can repave 1/15 miles of road each hour. they must repave a road that is 3/5 miles long. how long will it take the crew to repave the road?
Answer:
9 hours
Step-by-step explanation:
For this problem, we simply need to rewrite the goal length, 3/5 miles, into our ratio of time length equivalence, 1 hour per 1/15 miles. To do this we find the common denominator to be 15 and rewrite it as so:
3/5
= 3*3 / 5 * 3
= 9 / 15
And since it takes 1 hour per 1/15 mile of road, we can perform the division to find the amount of time:
9/15 / 1/15
= 9/15 * 15/1
= ( 9 * 15 ) / ( 15 * 1 )
= 9 / 1
= 9
Hence, it will take the crew 9 hours to repave the road.
Cheers.

Need help ASAP please
Answer:
$45
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 = 8 parts
Divide the amount by 8 to find the value of one part of the ratio.
$120 ÷ 8 = $15 ← value of 1 part of the ratio, thus
3 parts = 3 × $15 = $45 ← amount David received
Answer:
$45
Step-by-step explanation:
ratio is 3:5
David gets 3x, Jack gets 5x
So, 3x+5x=120
8x=120
x=15
David got 3x = 3*15 = $45
