Answer:

x = \frac{32}{45}

Step-by-step explanation:

Given

1 * (2\frac{2}{3}) = \frac{1}{2}x + 3\frac{1}{4}x

Required

Solve for x

Express all fractions as improper

1 * \frac{8}{3} = \frac{1}{2}x + \frac{13}{4}x

Take LCM

1 * \frac{8}{3} = \frac{2 + 13}{4}x

\frac{8}{3} = \frac{15}{4}x

Cross Multiply

15x * 3 = 4 * 8

45x = 32

Make x the subject

x = \frac{32}{45}

During a fireworks show, a rocket is fired vertically upward with an initial velocity of 200 meters per second. The height in me
My name is Ann [436]

Answer:

<h2>The rocket can safely explode in 10 ≤ t ≤ 30 seconds (see the last line of explanation).</h2>

Step-by-step explanation:

The height of the rocket is shown by s = 200t - 5t^{2}, where t is the time in seconds.

\frac{ds}{dt} = 200 - 10t. The height will be maximum when, \frac{ds}{dt} = 0 that is t = \frac{200}{10} = 20.

At t = 20, s = 4000 - 2000 = 2000.

The rocket can go 2000 meter maximum.

In order to explode safely, the rocket must be in a height equal or above 1500 meter.

When s = 1500, 1500 = 200t - 5t^{2} \\t^{2} - 40t + 300 = 0\\t^{2} - 30t - 10t + 300 = 0\\t = 30,10.

Hence, at 10 \leq t \leq 30, the height s \geq 1500.

Organizing a data set allows you to do each of the following except:
kicyunya [14]

Answer:

B. take up less space than when the data set is not organized

Step-by-step explanation:

Well, in this question, you can analyze one answer after the other.

In A see important values in the data set, this makes sense when determining mode and median of a data set.Median is the center value in a data set, while mode is the repeated value in the set.When data set is arranged from smallest to the largest, the median and mode can be seen clearly.These can be the important values in the data set

In C. More easily see the maximum and minimum values in the data set, is possible especially when data is arranged in an increasing order.The smallest value will start, where as the largest value will be at the end.This applies to D too.

However in B, it will depend with the manner you would like to analyze the data.For example organizing data using tables will make your data easy to understand and present your analysis.Another person will group the data in intervals to identify the frequency of in data set.So, you see, its not about space taken by data but how you would like to present your data when analyzing it.

Hope this helps.
