Given that there were 30 bacteria present originally.
a=30
Also given that the number doubles every one hour.
After one hour the count =2×30=60
Since the count doubles every hour it forms a G.P. with r=2
a,ar,ar2........
The count at the end of 2nd hour=ar^2=30×2^2=120
The count at the end of 4th hour=ar^4=30×2^4=480
The count at the end of 8th hour=ar^8n=30×2^8=7680
etc.
The count at the end of n^th hour=ar^n=30×2^n
Also, the equation y=30*(2)^8/1 give the same result y= 7680

Answer:
x=2y-3
Step-by-step explanation:
x=Jan's age
y=Tritt's age
<u><em>Answer: B. m=-23 and -23=m. *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
add by 10 both sides of equation.
m-10+10=-33+10
simplify.
33-10=23
23+10=33
33-23=10
m=-23
It changes positive to negative.
Hope this helps!
Thanks!
Have a great day!
Answer:
Value of x = 7/5
Step-by-step explanation:
Given:
ΔVUW ≅ ΔUST
Find:
Value of x
Computation:
We know that;
ΔVUW ≅ ΔUST
So,
VU = US (By CPCT)
So,
5x + 11 = 18
5x = 7
Value of x = 7/5
