The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate thei

r unit rate in miles per hour?
three-fifths over three-eights equals one and three-fifths miles per hour

three-eighths over three-fifths equals one and three-fifths miles per hour

three-eighths over three-fifths equals five over eight mile per hour

three-fifths over three-eights equals five over eight mile per hour

Velocity=distance/time

v=d/t

So in this case:

v=(3mi/5)/(3hr/8)  that's the equation you need to solve.

v=(3m/5)*(8/3hr)

8/5 mph=(3m/5)*(8/3hr)

1 3/5 mph= (3/5)/(3/8)

So the first statement is correct.

The points ????(0,0), ????(−4,1), ????(−3,5), and ????(1,4) are the vertices of parallelogram OABC Is this parallelogram a
gavmur [86]

Answer:

Yes, parallelogram OABC is a rectangle.

Step-by-step explanation:

The vertices of a parallelogram are O(0,0), A(-4,1), B(-3,5) and C(1,4).

A parallelogram is a rectangle if its any two adjacent sides are perpendicular to each other.

product of slopes of two perpendicular lines is -1.

Formula for slope is

Slope=\dfrac{y_2-y_1}{x_2-x_1}

Using the formula we get

m_{OA}=\dfrac{1-0}{-4-0}=-\dfrac{1}{4}

m_{AB}=\dfrac{5-1}{-3-(-4)}=-\dfrac{4}{1}=4

m_{OA}\times m_{AB}=-\dfrac{1}{4}\times 4=-1

It means OA is perpendicular to AB.

Since two adjacent sides are perpendicular, therefore the given parallelogram OABC is a rectangle.

What is the solution to log (9x)-log2^3= 3?
olga_2 [115]

For this case we have that by definition of properties logarithm is met:

log_ {b} (x) -log_ {b} (y) = log_ {b} (\frac {x} {y})

So, rewriting the expression we have:

log (\frac {9x} {2 ^ 3}) = 3\\log (\frac {9x} {8}) = 3

By definition of logarithm we have to:

log_ {b} (x) = yis equivalent tob ^ y = x

So:

10 ^ 3 = \frac {9x} {8}\\9x = 8 * 10 ^ 3\\9x = 8 * 1000\\9x = 8000\\x = \frac {8000} {9}

ANswer:

x = \frac {8000} {9}
