The pH of water is a measure of its acidity. The pH of the water on the Seal Slide can vary up to 0 3 from the target of a pH of 75. Use this information to write an equation that would tell you the highest and lowest pH values that are allowable.

7.5 - t = 0.3

p0.3 = 7.5

P-7.5 = 0.3

17,5 - 0,3)=P

think about it deeply and passionately about this property

i am sorry

eve and marks ratios are equivalent

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
