Mitch has a swimming pool in his backyard. The rectangular swimming pool has a volume of 243 m cubed. The length of the pool is

9 m. His neighbor is building a pool with the same dimensions except the length of the pool will only be 3 m. What is the volume of his neighbor's pool?

Answer:

81m^{3}

Step-by-step explanation:

Since the question states that the only difference would be the length of the neighbor's pool then this is basically a ratio problem. Therefore, since the question provides 3 values and one variable we can solve this using the Rule of Three which takes the diagonal values multiplies them together, and divides by the last sole value to get calculate the variable like so...

243 m^{3} volume  <=====>  9 m length

x m^{3} volume  <=====>  3 m length

(3* 243) / 9 = 81m^{3}

Therefore, the volume of the neighbors pool will be 81m^{3}

Which of the following is the statement of the triangle inequality theorem?
kupik [55]

we know that

<u>The triangle inequality theorem</u> states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

so

Let

a,b,c------> the length sides of a triangle

The theorem states that three conditions must be met

<u>case 1)</u>

a+b > c

<u>case 2)</u>

a+c > b

<u>case3)</u>

c+b > a

therefore

<u>the answer is the option</u>

B. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Find the first five terms of the recursive sequence <br> an=-6an-1 where a1=4.5
grandymaker [24]

Answer:

4.5, -27, 162,-972, 5832

Step-by-step explanation:

The given recursive definition is,

a_n=-6a_{n-1}, a_1=4.5

This will form a geometric sequence with first term 4.5 and common ratio r=-6.

When n=2, we have:

a_2=-6a_1 \\  \implies \: a_2=-6 \times 4.5 =  - 27

When n=3, we get:

a_3=-6a_2 \\  \implies \: a_3=-6 \times  - 27 =  162

When n=4, we get:

a_4=-6a_3 \\  \implies \: a_4=-6 \times 162 =  - 972

When n=5, we get:

a_5=-6a_4 \\  \implies \: a_5=-6 \times  - 972 = 5832

Therefore the first five terms are:

4.5, -27, 162,-972, 5832

Solve for x: (5 points) -6/5x - 4 = -46
Alecsey [184]

Answer:x5

Step-by-step explanation:Let's solve your equation step-by-step.

4x+2=2x+12

Step 1: Subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

Step 2: Subtract 2 from both sides.

2x+2−2=12−2

2x=10

Step 3: Divide both sides by 2.

2x

2

=

10

2

x=5
