Hello,

$2^{\frac{2}{3}}=\sqrt[3]{2^2} =\sqrt[3]{4}$

The correct answer is the first option. Two to the power of 2 over 3 is best defined by <span>Cube root of 4. It is best understood when written in numbers.

2^(2/3)

The denominator here represents the radical and the numerator is the power by which the base is raised. Therefore, it can be written as:

</span>∛2^2 or ∛4<span>

A jet flies over the Air Force Base at 10:20 a.m. At 10:32 a.m., the plane passes over the Navy Base Station, 120 miles away. Ho

kati45 [8]

So first calculate the time between the plane flied over the Air Force Bases (AFB) and Navy Base Station (NBS):
(time passed Air Force Bases) - (time passed Air Force Bases) = 10:32 - 10:20 = 12 mins
Since we know the distance that plane travel from AFB to NBS is 120 miles and the plane traveled that distance within 12 minutes.
We have
120 miles / 12 minutes = 10 miles / minute
Calculate it into miles per hour (60 minutes):
10 miles/minute x 60 minutes = 600 miles per hour.
ANSWER : 600 mph

The average of a data set is the number "in the middle" of all of the numbers. This is a measurement of the center of a data set. Another word for average is mean.

How to Calculate the Average

The average or mean is calculated by adding all of the values together. Then, divide this sum by the number of data points. For example, if the sum of 5 different data points is 10, then the average would be 10/5.

Finding the Average

Now, let's find the average of this specific data set. First, add all of the data together.

30+35+40+41+42+45+47 = 280

Then, count the number of terms. There are 7 different terms within this data set. So, next divide the sum by the number of terms.

280/7 = 40

This means that the average of the set is 40.

Other Measurements of Center

The mean is not the only measurement of center. There are 3 common measures of center.

The mean is found by adding all the terms and then dividing by the number of terms.
Another measurement is the median is found by ordering the terms from least to greatest, and then taking whatever number is left in the middle. The median of this set is 41.
Finally, the mode is the term that appears the most often. Many times there can be more than one mode. This set has no real mode because all of the terms only appear once.

1. m – 7 < 6 A) m < –1 B) m > 1 C) m < 13 <---------------------- D) m < –13 2. x + 4.5 ≥ 5.5 A) x ≥ 10 B) x ≥

ikadub [295]

1) m - 7 < 6
Add 7 to the both sides,
m - 7 + 7 < 6 + 7
m < 13

So, Option C is your answer for this part.

2) x+4.5 ≥ 5.5
Subtract 4.5 from both sides,
x ≥ 1

So, Option B is your answer for this part.

3) p +12 > 9
Subtract 12 from the both sides,
p > -3

So, Option D is your answer for this part.

4) x - 5 ≥ 9
So, Option A is your answer for this part

Hope this helps!

Betty can drive her car 400 miles at a steady speed using 20 gallons of gasoline. at this rate how many gallons of gas will she

ch4aika [34]

Answer:

80 gal

Step-by-step explanation:

20 gal takes her 400 mi

Vol. of gas = 1600 ×20/400

Vol. of gas = 1600 ×1/20

Vol. of gas = 80 gal

Betty will use 80 gal of gas.
