Ascientist has two solutions which she has labeled solution and solution be each contain salt she knows that solution eight is 40% salt in solution p is 90% so she wants to obtain 30 ounces of a mixture that is 80% salt how many ounces of each solution should she use

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

12
