In a right triangle ABC, CD is an altitude, such that AD=BC. Find AC, if AB=3 cm, and CD= root 2 cm.

Nata [24]

Given CD is an altitude such that AD=BC , AB=3 cm and CD= √2 cm.

Let AD=x, Since given AB=3

AD+DB=3

x+DB = 3

DB = 3-x

Since ΔBCD is rght angle triangle, let's apply Pythagoras theorem

$BC^{2} = DB^{2} +CD^{2}$

$BC^{2} = (3-x)^{2} +(\sqrt{2} )^{2}$

$BC^{2} =(3-x)^{2} +2$

Since given AD=BC,let us plugin BC=x in above step.

$x^{2} =(3-x)^{2} +2$

$x^{2} =9-6x+x^{2} +2$

6x=11

x= $\frac{11}{6}$

Now we know AD=x= $\frac{11}{6}$ and given CD=√2.

Let us apply Pythagoras theorem for ΔACD

$AC^{2} =AD^{2} +DC^{2}$

$AC^{2} = (\frac{11}{6} )^{2} +(\sqrt{2} )^{2}$

$AC^{2} =\frac{193}{36}$

$AC=\sqrt{\frac{193}{36} }$ = 2.315cm

Answer:

3. is 3 (m - 16)(m + 4)

7. is also 3. (2x + 5)(3x - 5)

12. is 4 (x - 6)(x - 4)

the last one is i dont know

Wildflower mix contains several different types of seeds.

Sveta_85 [38]

The chance would be 9.52% (rounded) because you would take the total number of seeds (63) and divide the number of poppy seeds by the total.
Then you would convert decimal fraction by multiplying it by 10.

Decrease 216 by 37 1/2%

Anon25 [30]

Step-by-step explanation:

In this question we need to decrease 216 by $37\dfrac{1}{2}\%$ or 37.5 %.

For this, firstly find 37.5 % of 216.

$37.5\%\ \text{of}\ 216=\dfrac{37.5}{100}\times 216\\\\=81$

Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.

So,

216-81 = 135

Hence, 135 is the decrease of 216 by 37.5 %.
