What are the minimum and maximum distances that Morgan’s dog may be from the house? (Algebra ll) *URGENT*
Mashcka [7]

Given:

The minimum and maximum distance that the dog may be from the house can be found by using the equation:

|x-500|=8

To find:

The minimum and maximum distance that the dog may be from the house.

Solution:

We have,

|x-500|=8

It can be written as:

x-500=\pm 8

Adding 500 on both sides, we get

x=500\pm 8

Now,

x=500+8 and x=500-8

x=508 and x=492

The minimum distance is 492 meters and the maximum distance is 508 meters.

Therefore, the correct option is C.

Plz help me solving this question ​
ankoles [38]

Answer:

Step-by-step explanation:

3) Surface area of cube = 6a² where a is side of the cube.

a)  a = 6 cm

Surface area of cube = 6 * 6*6 = 216 cm²

b) a = 4.5 cm

Surface area of cube = 6 * 4.5 * 4.5 = 121.5 cm²

4)  Area of cuboid = A = 2(lb + bh + hl)

a) l = 10 cm ; h = 6 cm  ; A = 376 cm²

  A = 376

2(lb + bh + hl) = 376

2(10b + 6b + 60) = 376

2*( 16b + 60) = 376

 2*16b + 2*60 = 376

     32b + 120 = 376

        32b  = 376 - 120

          32b = 256

             b = 256 / 32

b = 8 cm

5) Surface area  of cube = 150 cm²

6a² = 150

Divide both sides by 6

a² = 150/6

a² = 25 = 5*5

a = 5 cm

6)  l = 15 cm ; b = 12 cm ; h = 10cm

Lidless. so area of top portion is not included

Surface area of lidless cuboid = 2(hb + hl) + lb

                                                  = 2*(10*12 + 10*15) + (15*12)

                                                  = 2*(120 + 150) + 180

                                                  = 2* 270 + 180

                                                  = 540 + 180

                                                   = 720 cm²

What are the next three terms of the sequence below?
vichka [17]

<u>Answer:</u>

  • 64, 256, 1024 (D)

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

The sequence is following some rule. And the rule is: Multiplying the term with 4 to get the next term. Like:

  • 1 × 4 = 4
  • 4 \times 4 = 16

Similarly, the next terms are:

  • 16 \times 4 = 64
  • 64 \times 4 = 256
  • 256 \times 4 = 1024

The terms are <u>6</u><u>4</u><u>,</u><u> </u><u>2</u><u>5</u><u>6</u><u>,</u><u> </u><u>1</u><u>0</u><u>2</u><u>4</u> which matches with Option D. And that's the correct answer
