The amount of bacteria cells that would be in the petri dish after 30 minutes is 73.3
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the number of cells after x minutes, hence:
y = 4.2(1.1)ˣ
After 30 minutes:
y = 4.2(1.1)³⁰ = 73.3
The amount of bacteria cells that would be in the petri dish after 30 minutes is 73.3

Answer:
2(x + 10)
Step-by-step explanation:
The perimeter is all the sides added together so you times the length by 2, (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) add them together
16 + 2x + 4
2x + 20
take out the highest common factor of 2
2(x + 10)
Answer:
-10
Step-by-step explanation:
Answer:
Step-by-step explanation:
a square has sides that are all the same length. That means that if we have a diagonal of a square that measures 10, using Pythagorean's Theorem,
and
