Answer:
49 third graders
Step-by-step explanation:
From the question:
The music teacher receives 9 boxes of recorders and there are six recorders in each box
The total number of recorders the teacher received =
1 box = 6 recorders
9 boxes = x
Cross Multiply
x = 9 × 6 recorders
x = 54 recorders.
She hands them out to third graders and has 5recorders left .
How many third graders received a recorder?
The amount of recorders shared =
54 recorders - 5 recorders
= 49 recorders
If 1 recorders was given to a third grader,
Therefore, the amount of third graders that received a recorder is 49 third graders
1.75 inches and how you get that is 7 Divided by 8 which equals 0.875<span> </span><span>then multiply that by 2 equaling 1.75</span>
1/4 should be the answer :)
Answer:
<em>The half life of the sample is </em><em>6301 years.</em>
Step-by-step explanation:
The function used to model radioactive decay or exponential decay is,
Where,
Q(t) = Quantity after t time
Q₀ = Initial
k = decay constant
t = time period
As after an half life, the amount becomes half so,
Taking natural log of both sides,
