Answer:
19.6
Step-by-step explanation:
The ratio of brown paint to white paint is, 5:7 or
so if he bought 14 gallons of white paint we need to figure out:

which we can as it only has one unknown:
5x=14×7
5x=98
x=19.6
So the answer is 19.6
The acceleration is defined as the ratio between the change in velocity and the time elapsed to perform such a change.
These "changes" are indicated with the capital greek letter delta,
, and when you write
you mean the difference between the finial and the inital values of the variable x:

So, the acceleration is defined as

In this case, the initial velocity is 35, the final velocity is 65. Assuming we start the clock at the beginning of the observation, the inital time is 0 and the final time is 5. So, we have
m/s^2
the real solutions for the equation
are -

Step-by-step explanation:
= 
= 0
We can write 64 as
+
= 0
using the identity (
)
we get,
= 
=
....................(1)
solving the quadratic equation ,
=0
solutions of this quadratic equation can be obtained by

let use y for factors




<u />
..................(2)
from the equation 1 we have,

which gives solution
and from equation 2 we got 
so the real solutions for the equation
are -

remember, 7 days each week, so this is a multiplication problem.
32*7=224 days
Done!
Answer:
3
Step-by-step explanation:
Pythagorean Theorem: a²+b²=c²
You can fill in the numbers you know: a²+4²=5²
(Hypotenuse must be side c)
Square those numbers and you have: a²+16=25
Subtract 16 from both sides: a²=9
Square root both sides and you get: a=3
