Isn't that simply asking you to compute 30% of 20?

30 x

----- = ------

100 20

100x = 600

x = 6

So, out of those 20 numbers, you would expect that 6 of them would begin with the digit 1.

A rhombus has its diagonals 7cm and 6 cm whats its area

ipn [44]

$\large\frak{ Given :}$

Diagonal of a rhombus = 7 cm and 6 cm

$\large\frak{Find:}$

Area of a rhombus

$\large\frak{Explanation :}$

$\small\tt Area = \frac{1}{2}× d¹ × d²$

Where,

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

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

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

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

X^2 -50x+456=0 solve this algebraiclly find x

bagirrra123 [75]

Answer:

$x=-406$

Step-by-step explanation:

$x^2-50x+456=0$

$x^2-50x=-456$

This is because we subtract 456 from each side.

$x-50=-456$

We then divide the whole equation by x .

$x=-406$

Adding 50 to both sides gives us x by itself, hope this helps :D
