Answer:
1. Two ribbons, A and B. One third of A is equal to all of B. Draw a tape diagram to show the ribbons.
2. Half Robert’s piece of wire is equal to 2/3 of Maria’s wire. The total length of their wires is 10 feet. How much longer is Robert's wire than Maria's?
3. Half Sarah’s wire is equal to 2/5 of Daniel’s. Chris has 3 times as much as Sarah. In all, their wire measures 6 ft. How long is Sarah’s wire in feet?
The answer would be...
1/2n - 1/6n = 10 + 1/8n
^^^That would be the last one

19539 bacteria will be present after 18 hours
<u>Solution:</u>
Initial value of bacteria N = 6000
Value after 4 hours = 7800
<em><u>The standard exponential equation is given as:</u></em>
where
N is amount after time t
No is the initial amount
k is the constant rate of growth
t is time
Plugging in the values in formula we get,
Solving for "k" we get,
Taking "ln" on both sides, we get
On solving for ln, we get k = -0.0656
The equation becomes,
Now put "t" = 18,
Hence the bacteria present after 18 hours is 19539
D. 29.25 yards is your answer
The more precise the measurement, the more decimals would be given (unless it is TRULY a whole number amount)
hope this helps
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the point is ( 5 , - 2) and slope is - 2/5
The equation of the line is
We have the final answer as
