Answer:

y=\frac{2}{5}x-5

Step-by-step explanation:

y=\frac{2}{3}x+4

the line parallel  to this line is

y=\frac{2}{3}x+k ; k ∈ R

the line passes through the point (3,6)

so,

6=\frac{2}{3} (3)+k\\6=2 +k\\k=4

∴the line that passes through point (2, -1) and is parallel to the line described y = (2/3)x - 6 is

y=\frac{2}{3}x+4

Answer:

\boxed{0.2}

Step-by-step explanation:

Convert \dfrac{12}{60} to a decimal

Step 1. Reduce the fraction to its lowest terms.

Divide both numerator and denominator by their greatest common factor (12)

\dfrac{12}{60} =\dfrac{1}{5}

Step 2. Convert the denominator to a power of 10

Multiply both numerator and denominator by 2.

\dfrac{1}{5} \times \dfrac{2}{2} = \dfrac{2}{10}

Step 3. Divide the numerator by the denominator

Dividing by 10 moves the decimal point one place to the left.

\dfrac{2}{10} = \boxed{0.2}

Can someone please help with this
mash [69]

Answer:

   3. 43.96 cm

  4. 81.64 ft

Step-by-step explanation:

3. The formula for the circumference of a circle in terms of radius is ...

  C = 2πr

When π is approximated by 3.14, this becomes ...

  C ≈ 6.28r

The only answer choice even close to 6.28×(7 cm) is the one shown above.

___

4. The formula for the circumference of a circle in terms of diameter is ...

  C = πd

When π is approximated by 3.14, this becomes ...

  C ≈ 3.14d

The only answer choice anywhere close to 3.14×(26 ft) is the one shown above.

_____

<em>Comment on the solution</em>

For questions like these, you only need to be able to estimate the answer to 1 or 2 significant digits. The answer choices are not so close together as to cause any confusion.

6×7 = 42, so the answer will be a few more than 42.

3×26 = 78, so the answer will be within a few numbers larger than that.

In each case, the answer is the largest value on the list. The other choices differ by a factor of 2, so aren't even close.

Answer:

Total area to be painted in gold = 24000 cm²

Step-by-step explanation:

Total height of the stairs = 120 cm

Total standing stairs = 4

Therefore, height or width of one standing stair as shown in the picture,

= \frac{120}{4}

= 30 cm

Length of every stair has = 100 cm

Every horizontal and vertical stair has the same area.

Area of one stair = Length × Width

                            = 100 × 30

                            = 3000 cm square

There are 4 horizontal and 4 vertical similar stairs to be painted in gold.

Total area to be painted in gold = 8 × Area of one stair

                                                     = 8 × (3000)

                                                     = 24000 cm²

Total area to be painted in gold = 24000 cm²
