Answer:

39 units

Step-by-step explanation:

area of polygon = area of rectangle VERD + area of triangle MVR

[length of rectangle (6) * width of rectangle (5)] + [1/2 * 3 (height of triangle) * 6 (height of triangle)] = area of polygon

(6*5) + (1/2*3*6) = area of polygon

30 + 9 = area of polygon

area of polygon = 39

$\bf f=k\sqrt{t}\quad \textit{we also know that }

\cfrac{300}{\sqrt{8}}=k\implies \cfrac{300}{\sqrt{2^2\cdot 2}}=k\implies \cfrac{300}{2\sqrt{2}}=k\implies \cfrac{150}{\sqrt{2}}=k

When 31 times a number is increased by 40, the answer is the same as when 200 is decreased by the number. Find the number.

natulia [17]

Answer:

The Answer is: 5.

Step-by-step explanation:

Let n = number.

The number times 31 plus 40 is equal to 200 minus the number:

31n + 40 = 200 - n

32n = 200 - 40

32n = 160

n = 5

Proof:

31(5) + 40 = 200 - 5

155 + 40 = 195

195 = 195

Hope this helps! Have an Awesome Day!! :-)

Answer:

The only option 3 is correct

Step-by-step explanation:

See the given diagram.

1. ∠ D = ∠ B {Since AB ║ DE and DB is transverse line. So, they are alternate angles.}

So, ∠ D = 43° ≠ 28°

2. Now, ∠ A = ∠ CED {Again they are alternate angles}

⇒ ∠ A = ∠ CED = 180° - ∠ CEF = 180° - 152° = 28° ≠ 43°.

3. Again, ∠ ACD = 180° - ∠ ACB = ∠ A + ∠ B = 28° + 43° = 71°.

4. ∠ BCE = ∠ ACD {Vertically opposite angles}

⇒ ∠ BCE = 71° ≠ 109°

Therefore, the only option 3 is correct. (Answer)
