8.2
3 does not add 1 to 2 so it's 8.2
Answer:
sample size at the beginning was 40 bacteria.
Step-by-step explanation:
Given that a sample of bacteria experienced 5% daily growth compounded continuously for 14 days
Let C be the initial amount of bacteria.
C grows continuously compounding at the rate of 5%
The equation representing the number of bacteria at time t days would be
Now we have t = 14 days and P = 80.
Substitute to get
Approximately 40 bacteria were present at the beginning.
To get the percentage of a number, change the percentage to decimal form and multiply it by the number. So in this case,
21000 x 0.0525 = 1102.5
Make sense?
Answer:
x=6
Step-by-step explanation:
Since both have the same base,
5x-8 = 22
5x = 22+8
5x = 30
x= 30 ÷ 5
x= 6
1. 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
2. 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.
<h3>What is the Commutative Property of Multiplication?</h3>
The commutative property of multiplication states that the arrangement of change of numbers that you want to multiply does not change what you would get as the product.
For example, a × b = b × a.
In the same vein, 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
<h3>What is the Commutative Property of Addition?</h3>
The commutative property of addition also states that the order or arrangement of addends will not change the sum you would get.
For example, 3 + 2 = 2 + 3.
Therefore, the statement, 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.
