Answer:
3.5 cm
Step-by-step explanation:
Perimeter of rectangle = 2 × (w + h)
w = width
h = height
We have: 2 x (w + 6) = 19
w + 6 = 19 : 2 = 9.5
w = 9.5 - 6 = 3.5 (cm)

=57 times 4/57 times 2
=57/1 times 4/57 times 2
=4/2 times 2 (cancel common factor:57)
=4/1 times 2 (convert element to fraction 2= 2/1)
=4/1 times 2/1
Multiply the numbers (4 times 2)
=8/1 times 1 (Multiply the numbers 1 times 1)
Apply the fraction rule: a/1 =9
=8
Answer:
C) 148.413
Step-by-step explanation:
ƒ(t) = et
Where ƒ(t) = number of bacterials present at a particular time t.
So let's determine the number of bacterial present at 5 hours
ƒ(t) = et
ƒ(5) = e(5)
ƒ(5) = 148.413
Approximately= 148 in whole numbers.
So the number of bacterial present at 5 hours is approximately 148 bacterial.
Let's remember we solved it from the equation ƒ(t) = et .
