This is a geometric sequence of the form:

a(n)=ar^n, a=initial value, r=common ration, n=term number, if we relabel it for h(b) we have

h(b)=14(0.8^b)

h(3)=14(0.8^3)

h(3)≈7.2 ft (to nearest tenth of a foot)

Solve the inequality <br> 3x/2- 2 > 7

In-s [12.5K]

Answer:

<h3>NO SOLUTIONS</h3>

Step-by-step explanation:

To solve this problem, first, you have to isolate x on one side of the equation.

3x/2-2>7

3x/2-2-7>7-7 (First, subtract 7 from both sides.)

7-7 (Solve.)

7-7=0

3x/2-2-7>0

3x/2-2*0-7*0>0*0 (Then, multiply 0 from both sides.)

0*0 (Solve & simplify.)

0*0=0 (undefined & no solutions)

In conclusion, there are no solutions.

3) A committee has 45 members. The number of men on the committee is 6 less than twice the number of women. Which expression rep

almond37 [142]

<h2>m=(2xw)-6</h2>

Step-by-step explanation:

Let the number of women in the committee be $w$ .

Let the number of men in the committee be $m$ .

Since it is given that the number of men are 6 less than twice the number of women,

Twice the number of women is $2\times m$

Twice the number less six is $m=2\times w -6$ $-(i)$

Since it is given that the committee has a total of 45 members,

the total number of men and women is 45.

So, $m+w=45$ $-(ii)$

using (i) and (ii),

$2\times w-6+w=45$

$3\times w-6=45\\3\times w=51\\w=17$

$So,m=2\times 17 -6\\m=28$
