\large\frak{ Given :}

  • Diagonal of a rhombus = 7 cm and 6 cm

\large\frak{Find:}

  • Area of a rhombus

\large\frak{Explanation :}

\small\tt Area = \frac{1}{2}× d¹ × d²

<u>Where,</u>

  • d¹ = length of diagonal 1
  • d² = length of diagonal 2

\implies \small\tt{ \frac{1}{2}  \times 7 \times 6}

\implies\small\tt{ \frac{1}{2} \times 42 }

\implies \small\tt{Area = 21  {cm}^{2}  }

Brian &amp; Paul share a lottery win of £7800 in the ratio 1 : 4. Brian then shares his part between himself, his wife &amp; the
Elza [17]

Answer:

The wife gets £468 over the son

Step-by-step explanation:

Firstly, we shall calculate the total amount Brian made from from what he and Paul won.

The ratio is 1:4, meaning for every 2 part Brain takes, Paul takes 4

Paul’s share is thus 1/5 * 7800 = 7800/5 = £1560

Now we have another ratio for sharing the amount Brain has at home.

The total ratio here is 1+6+3 = 10

The share of the wife will be 6/10 * 1560 = 6 * 156 = 936

The son share is half of this which is 936/2 = 468

The difference between their shares is £936-£468 = £468

What is the product of z1 and z2 if
MaRussiya [10]

Answer:

308[cos(45) + isin(45)]

Step-by-step explanation:

z1×z2:

Modulus: r1 × r2

= 7×44 = 308

Argument: theta1 + theta2

= -70 + 115 = 45

z1z2 = 308[cos(45) + isin(45)]

Or

z1z2 = 154sqrt(2) + (i)154sqrt(2)

sqrt: square root
