The answer is 1920 because 320 divided by two is 160 and 160 x 12 equals 1920.

"a man drove 11 mi directly east from his home, made a left turn at an intersection, and then traveled 2 mi north to his place o

Charra [1.4K]

Pythagorean therom!

east and the north make a right angle

a^2 + b^2 = c^2
(11)^2 + (2)^2 = c^2
121 + 4 = c^2
125 = c^2
11.2 miles = c

84. Use properties of exponents to rewrite each expression with only positive, rational exponents. Then find the numerical value

Yakvenalex [24]

Answer:

a) 1/27

b) 16

c) 1/8

Step-by-step explanation:

a) $x^{-3/2}$

One of the properties of the exponents tells us that when we have a negative exponent we can express it in terms of its positive exponent by turning it into the denominator (and changing its sign), so we would have:

$x^{-3/2}=\frac{1}{x^{3/2} }$

And now, solving for x = 9 we have:

$\frac{1}{x^{3/2}}=\frac{1}{9^{3/2} } =\frac{1}{27}$

b) $y^{4/3}$

This is already a positive rational exponent so we are just going to substitute the value of y = 8 into the expression

$y^{4/3}=8^{4/3}=16$

c) $z^{-3/4}$

Using the same property we used in a) we have:

$z^{-3/4}=\frac{1}{z^{3/4} }$

And now, solving for z = 16 we have:

$\frac{1}{z^3/4} } =\frac{1}{16^{3/4} } =\frac{1}{8}$

coach Park's car averages 33 miles per gallon of gasoline how many gallons of gas does he need for the trip? justify you answer

sladkih [1.3K]

Since we don't know the length of the trip, we can't find an exact answer.

However, we can write an expression for it. First, we let, T, represent the total number of miles for the trip.

Now, just divide T by 33. So our expression is T/33.

If you know the total miles of the trip, just divide it by 33 and you will have the answer.
