Answer:

\textsf{D. }x\leq-2

Step-by-step explanation:

<u>Given inequality:</u> 3(x+2)\leq5(-2-x)

Step 1: Distribute 3 and 5 through the parentheses.

\implies 3(x)+3(2)\leq5(-2)+5(-x)

\implies 3x+6\leq-10-5x

Step 2: Subtract 6 from both sides.

\implies 3x+6-6\leq-10-6-5x

\implies 3x\leq-16-5x

Step 3: Add 5x to both sides.

\implies 3x+5x\leq-16-5x+5x

\implies 8x\leq-16

Step 4: Divide both sides by 8.

\implies \dfrac{8x}{8}\leq\dfrac{-16}{8}

\implies x\leq-2

Answer:

x ≤ -2

Step-by-step explanation:

3(x + 2) ≤ 5(-2 - x)

Distribute on both sides.

3x + 6 ≤ -10 - 5x

Add 5x to both sides.

8x + 6 ≤ -10

Subtract 6 from both sides.

8x ≤ -16

Divide both sides by 8.

x ≤ -2

They are not the same but very close, the reasoning for this is that theoretical things are not 100% accurate therefore meaning that the answers with a real experiment may vary.

How many different 10 person committees can be selected from a pool of 23 people?
Salsk061 [2.6K]

We're going to be using combination since this question is asking how many different combinations of 10 people can be selected from a set of 23.

We would only use permutation if the order of the people in the committee mattered, which it seems it doesn't.

Formula for combination:

C(n,r)=\dfrac{n!}{(n-r)!r!}

Where n represents the number of objects/people in the set and r represents the number of objects/people being chosen from the set

There are 23 people in the set and 10 people being chosen from the set

C(23,10)=\dfrac{23!}{(23-10)!10!}

=\dfrac{23!}{13!\times10!}

Usually I would prefer solving such fractions by hand instead of a calculator, but factorials can result in large numbers and there is too much multiplication. Using a calculator, we get

=1,144,066

Thus, there are 1,144,066 different 10 person committees that can be selected from a pool of 23 people. Let me know if you need any clarifications, thanks!

PART - A : tent - 1 volume = 400 cubic ft

Tent -2 volume = 384 cubic ft.

PART - B : I recommend Joe to make the tent -1 with base 10x10 ft. as it has more volume

<u>Step-by-step explanation:</u>

PART - A:

tent 1 :

 Base = 10 x 10ft

 Height= 12 ft

 Volume = (1/3) (10x 10) (12)

 = (1/3) (100) (12)

= 400 cubic ft.

Tent 2:

 Base = 12 x 12 ft

 Height= 8 ft.

 Volume = (1/3) (12 x 12) (8)

= 384 cubic ft.

PART - B:

I recommend Joe to make the tent -1 with base 10x10 ft. as it has more volume
