Jenny studied the characteristics of two species of bacteria.
The number of bacteria of species A, A(t), after t hours is represented by the function:
The number of bacteria of species B, B(t), after t hours is represented by the function:
N(t) denotes the difference in the number of bacteria; hence N(t) is given by after t hours as:
N(t)=A(t)-B(t)
which on simplifying gives:
Hence,
Answer:
$5.21
Step-by-step explanation:
20.00 - 14.79 = 5.21
Answer:
D. 6 1/12
Step-by-step explanation:
First add the like fractions.
3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)
Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.
<h2>
REMEMBER: You can only add and subtract fractions when they have the same denominator.</h2>
3: 3, 6, 9, 12
4: 4, 8, 12
In this case 12 is the least common multiple.
3/4 x 3/3 = 9/12 9/12
4/3 x 4/4 = 16/12
Add those two fractions then add the whole numbers and put it in front.
4 25/12
Simplify
6 1/12
280÷7=40.
280-80 = 200.
200×280=5,600
Length divided by scale length to find the amount that each inch scale size equals 40 yards per inch.
5 inches equals 200 yards
Then multiply length times width.
200x280=5,600 yds
3.60
bc using a part to whole chart you cross multiply 24*15 get 360 then divide it by 100 and get 3.60
