Answer:To find 85% of a number multiply the number by .85
Step-by-step explanation: .85 = 85%
First, you would find out how much 1 gallon of gas would cost
You would calculate $19.46 divided by 14 gallons
Your quotient is $1.39
Then, you would divide how much money you actually have ( $8.70 ) by how much 1 gallon is ( $1.39 )
You get 6.25...
But since you cannot by 1/4 a gallon, you would round your quotient down to 6
Solution : 6 gallons
Mark brainliest if this helped :D
Answer:
4x - 2y = -8--------equation 1
y = 2x + 4
or, -2x+y=4---------equation 2
multiply equation 2 by 2 and solving equation 1and2 we get,
4x - 2y = -8
-4x+2y=8
---------------=
impossible
4 P 4 = 24
4 P 4 = 4! (4-4)! = 4!/1 = 4*3*2*1
you are doing combinatorics, yes?
Given :
Salt is poured from a container at 10 cm³ s-¹ and it formed a conical pile whose height at any time is 1/5 the radius of the above.
To Find :
At what rate is the height of the cone increasing when the height is 2 cm form the base of the cone.
Solution :
We know, volume of a cone is given by :
Also, h = r/5
r = 5h
Differentiating above equation w.r.t h, we get :
Hence, this is the required solution.
