Find the area of the left polygon and find the area of the right polygon
charle [14.2K]

Answer:

106 m²

Step-by-step explanation:

we can see in the figure that it is made up of one square and one trapezium

Formula to calculate the area of this polygon

Area of square + Area of trapezium

Area of square

side²

5²

25

Area of trapezium

\frac{a+b}{2}(h)

<em>here a and b is the parallel sides</em>

<em>         h is the height of trapezium </em>

\frac{6+3}{2}(21-3)

\frac{6+3}{2}(18)

(6+3)(9)

(9)(9)

81

Area of the polygon

25 + 81

10m3 of air weigh 13 kg.
sleet_krkn [62]

The constant of variation is 1.3 kg per m³

Step-by-step explanation:

Direct variation is when one variable is equal to a constant times

another variable, with no additions or subtractions alongside

If y is directly proportional with x, then

  • y ∝ x
  • y = k x, where k is the constant of variation
  • The graph of the variation is a line passes through the origin

∵ The weight of air is directly proportional to its volume

∴ The weight (w) ∝ the volume (v)

∴ w = k v

∵ w = 13 kg

∵ v = 10 m³

- Substitute these values in the rule of variation above to find k

∴ 13 = k (10)

∴ 13 = 10 k

- Divide both sides by 10

∴ k = 1.3

The constant of variation is 1.3 kg per m³

Solve l 3x-7 l = 2
Lelechka [254]

Answer:

1) Solutions are x = 3 and x = 5/3

2) Solution are x ≤ 13/2 and  x ≤ -3/2

Step-by-step explanation:

1) Given absolute inequality,

|3x-7| = 2

⇒ 3x - 7 = ± 2

⇒ 3x = 7 ± 2

\implies x=\frac{7\pm 2}{3}

x=\frac{7+2}{3}\text{ or }x=\frac{7-2}{3}

\implies x = 3\text{ or }x=\frac{5}{3}

2) l 2x-5 l ≤ 8

⇒  2x-5  ≤ ±8

⇒   2x ≤ 5 ± 8

\implies x\leq \frac{5\pm 8}{2}

x\leq \frac{5+8}{2}\text{ or }x\leq \frac{5-8}{2}

\implies x \leq \frac{13}{2}\text{ or }x\leq-\frac{3}{2}
