Answer:
c. 6 units
Step-by-step explanation:
The diameter of a circle with a circumference of 18.84956 is 6 units.
Use the formula: C=2πr
d=C
π=18.85
π≈6
This is FACTORISATION.
To solve this problem we have to find the common terms in this equation.
Firstly, between the 5x³ and 10x² the like terms are 5. But the question is, where did the 5 come from? Well in Factorisation, we have to find the HCF between two terms. Here is my answer:
5x³+10x²-25x-50
5x²(1x+2)-25(x+2)-› HCF of 5 and 10 is 5, HCF of 25 and 50 is 25
(1x+2)(5x²-25)-› Add the numbers from the brackets and the numbers outside the brackets.
SO THE ANSWER IS (1x+2)(5x+25)
HOPE THIS HELPS!!!! ;)
Answer:
C.
Step-by-step explanation:
as 0.05 is 1/10 of a number, multiplying 0.05 by 10 will give you the number that when divided by 10 will give you 0.05. Hence just multiply 0.05 by 10 and you get 0.5.

Answer:
157286400 bacteria
Step-by-step explanation:
We are given the following in the question:
The bacteria increases 4 times every 6 hours.
Initially there are 150 bacteria.
Thus, we can write the function for number of bacteria after x hours,
We have to find the number of bacteria in 2.5 days.
1 day = 24 hours
Thus,
Putting x = 60 in the above equation, we get,
Thus, there will be 157286400 bacteria in two and a half days.
