Answer the following
Amanda [17]

The set A satisfying the given inequality is A = (-\infty, -10].

<h3>What are some properties of an inequality relation? </h3>

Following are some facts which are true for an inequality relation:

  • Equal numbers can be added or subtracted from both sides of an inequality without affecting the inequality sign.
  • The Inequality sign is unchanged if both sides are multiplied or divided by a positive number, but when multiplied or divided by a negative number the inequality sign is reversed.

\frac{5x-2}{8} - \frac{3x-5}{10} &\ge& x+y\\\\\Rightarrow\;\; \frac{13}{40}x + \frac{1}{4}&\ge& x+y\\\\\Rightarrow\;\;\;\;\;\; -\frac{27}{40}x &\ge & y - \frac{1}{4}\\\\\Rightarrow\;\;\;\;\;\;\;\;\;\; -x &\ge & \frac{40}{27}\left( y-\frac{1}{4} \right).\hspace{1cm}(1)

Since y ∈ B, -2 ≤ y ≤ 7. So,

\;\;\;\;\;\;\;\,-2 - \frac{1}{4}\; \le\; y - \frac{1}{4} \;\le\; 7 - \frac{1}{4}\\\\\Rightarrow\;\;\;\;\;\;\;\;\; -\frac{9}{4}\; \le\;  y - \frac{1}{4} \;\le\; \frac{27}{4}\\\\\Rightarrow\;\;\; -\frac{9}{4}\cdot \frac{40}{27} \;\le\; \frac{40}{27} \left( y-\frac{1}{4} \right) \;\le \;\frac{27}{4}\cdot \frac{40}{27}\\\\\Rightarrow\;\;\;\;\;\;\;\; -\frac{10}{3} \;\le\; \frac{40}{27}\left( y - \frac{1}{4} \right)\; \le\; 10.

The set {-x | inequality (1) holds ∀ y ∈ B} is [10, \infty) i.e.

10 ≤ -x ≤ \infty.

Multiplying -1 throughout gives

-10 ≥ x ≥ -\infty.

x, thus, lies in the range A = (-\mathbf{\infty}, -10}.

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%

What does 8 yards equal in inches
melisa1 [442]
To do this, convert 8 yards to feet

Since there are 3 feet in a yard, multiply 8 by 3. You get 24

Then, since there are 12 inches in a foot, multiply 12 by 24

You get 288

Hope this helps!!
