Answer: 0.84 as a fraction is 84/100
Greatest common factor is 4
Resulting fraction is 21/25
Addition of numerator and denominator of the resulting fraction is 46
Step-by-step explanation:
From the question, the sum of 0.8 and 0.04 is written as 0.8 + 0.04 = 0.84
Convert 0.84 to fraction = 84/100
The numerator and denominator in 84/100 are both positive integers.
The greatest common factor to the numerator and denominator is 4
Divide 84 by 4 = 21
Divide 100 by 4 = 25
Therefore, the resulting fraction is 21/25
Addition of 21 and 25 equals 46.
I hope this helps.
Are we supposed to guess???
Answer:
Step-by-step explanation:
a = 5
r = -5
n = 9
t_9 = a r^(n - 1)
t_9 = (-1)^n*5 (-5) ^ 8
t_9 = (-1)^9 * 5 * (-5) ^8
t_9 = -1 ( 1953125)
t_9 = - 1953125

"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . 
"
Answer : 
Step-by-step explanation:
From the expression " y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.
we arrive at
for the expression 
we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have
.
if we make dy/dx subject of formula we arrive at
Work it exactly like the other one with Wilda and Karla.
Juan takes 15 hours to do a job ... he does 1/15 of it in an hour.
His father can do it in 6 hours ... he does 1/6 of it in an hour.
Juan works alone for 4.5 hours. In that time, he does 4.5/15 = 0.3
of the job. When his father joins him, there's only 0.7 of it to finish.
Working together, they do (1/15 + 1/6) = (2/30 + 5/30) = 7/30 of the job
each hour.
How many times do they have to do 7/30 of the job in order to finish
the 7/10 of it that remains ? That will be the number of hours they need.
(7/10) / (7/30) = 7/10 x 30/7 = <em>3 hours</em>.
Then they can knock off while it's still daylight, and go for a swim.
