Did you ever find the answer?
You can figure this out by setting up an equation and make
x= tens digit
y= ones digit
y + 8 =x (tens digit 8 more than ones)
also we know that
y>0
x>0
since the 10s digit and 1s digit cannot be more than one number, we can say
0 < y > 10
0 < x > 10
since x has to be greater than 0 but less than 10, there is only one number that would fit into the equation for y
2 + 8 = 10
(y cannot equal 2 because than x is equal to 10 and it must be less than)
1 + 8 = 9
( y can be 1 since x is less than 10)
so it would be
y= 1
x= 9
the number would be 91
hope this helped!
Answer:
1 hour and 42.8 minutes
Step-by-step explanation:
To answer this question let's call
while it takes Jenna to clean the gutters
Let's call
while it takes John to clean the gutters
h
h
t = total time
g = job = 1 (clean the gutters)
The speed of each one is:
g/ h
g/h

So:


h
Then, both together paint
of gutters for each hour.
This means that it takes
hours to clean the gutters together
Finally cleaning together takes 1,714 hours or also
1 hour and 42.8 minutes
The answer is that he spent 33 1/3% (A) on chicken.

Answer:
25.2 weeks until everyone on the planet is infected
Step-by-step explanation:
The number of infected people after t weeks has the following format:

In which P(0) is the initial number of infected people and r is the growth rate, as a decimal.
The number of infected people doubles every week
This means that 
So




So

200-person town
This means that 
So


How long will it be until everyone on the planet is infected?
This is t for which P(t) = 7700000000[/tex]
So







25.2 weeks until everyone on the planet is infected
