A set of equations is given below:

I would think this is many solutions, the reason is because, there is no specific answer (y) so, x could be anything because it would have to equal to y, which could also be anything! I hope im right! Sorry if im wrong!

in 1940, the u.s. army reported a total of 17,563 commissioned officers. of these, 939 were females. find the percent of female

Kisachek [45]

Answer: The percent of female commissioned officers in the army in 1940= 5.3%

Step-by-step explanation:

We are given that ,

The number of commissioned officers reported by U.S. Army in 1940 = 17,563

The number of female commissioned officers = 939

Then , the number of female commissioned officers in the army in 1940 would be :-

$\dfrac{\text{\text{Number of Female officers}}}{\text{Total commissioned officers }}\times100$

$=\dfrac{939}{17563}\times100=5.3464670\approx5.3\%$

Hence, the percent of female commissioned officers in the army in 1940= 5.3%

This distance-time graph represents a journey made by Jo.

ioda

Answer:

Jo started decelerating at the 10th minute

His average speed for the last 30 minutes of the journey is 4/30 km/minute

Step-by-step explanation:

To get what Jo did at 10 minute, we look at the graph.

At the 10th minute, we can see that we have a sharp turn from the top to the zero position at the 20th minute

so we can say that Jo started deceleration at the 10th minute

For the last 30 minutes of the journey, he travelled a distance of 4km

So, mathematically, his average speed will be;

Distance/ time = 4km/30 minutes = 4/30 km/minute

What is the length of CD? In this diagram, <br> ABC ~ EDC.

Alex777 [14]

Hey there!

Answer:

CD = 3.

Step-by-step explanation:

Since the triangles are similar, we can set up a ratio to determine the other side-lengths:

$\frac{12-x}{18} =\frac{x}{6}$

Cross multiply:

$6(12-x) = 18x$

Distribute the '6':

$72-6x = 18x$

Combine like terms and simplify:

$72 = 24x$

$x = 3$

Therefore, the length of CD is 3.
