On average, Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour.
sweet [91]
<h3>Stan drinks 12 ounces of water in 1 hour</h3>

<em><u>Solution:</u></em>

Given that,

Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour

Which means,

\frac{3}{4}\ of\ 8\ ounce = \frac{1}{2}\ hour

\frac{3}{4} \times 8 = 0.5\ hour\\

Therefore,

6 ounces is drank in 0.5 hour

We have to find the water he drinks in an hour

Let "x" be the water he drinks in 1 hour

Thus we get,

6 ounce = 0.5 hour

x ounces = 1 hour

This forms a proportion and we can solve the sum by cross multiplying

6 \times 1 = 0.5 \times x\\\\0.5x = 6\\\\x = \frac{6}{0.5}\\\\x = 12

Thus, he drinks 12 ounces of water in 1 hour

Which of the following points is on the graph of….
bonufazy [111]

we have the equation

y=\log_{\frac{1}{2}}x

Remember that

If an ordered pair is on the graph of the given function, then the ordered pair must satisfy the given function

Verify each option

N 1

(0,1)

x=0, y=1

Is not true, because the log of zero is undefined

N 2

(1,1/2)

x=1, y=1/2

Is not true, because the log of 1 is zero

N 3

(1/2,1)

y=\operatorname{\log}_{\frac{1}{2}}\frac{1}{2}=1

Is true

therefore

<h2>The answer is (1/2,1)</h2>
