Value of 3/4 + 1/5 is 19/20.

Do you need the steps?

First, calculate the LCM of the denominators (4 and 5) which is 20.

Now, divide 20 by 4 and 5 and multiply the quotient with the numerator.

(5×3) + (4×1)

=> 15+4

=> 19/20

Hope it helps!

Please mark as brainliest :D

Dustin is standing at the edge of a vertical cliff, 40 meters high, which overlooks a clear lake. He spots a fluffy white cloud

Licemer1 [7]

Answer:

53.33 meters

Step-by-step explanation:

Let AB represents the height of the cliff,

( where, A is top and B is bottom ),

Also, C and D represents the shadow of the cloud and cloud in the sky respectively,

Suppose E is a point in the segment CD,

Such that,

AB = DE = 40 meters,

According to the question,

$m\angle CAE = 30^{\circ}$

$m\angle EAD = 60^{\circ}$

Since,

$\tan =\frac{\text{Perpendicular}}{\text{Base}}$

$\implies \tan 60^{\circ}=\frac{DE}{AE}$

$\sqrt{3}=\frac{40}{AE}$

$\implies AE = \frac{40}{\sqrt{3}}$

Now,

$\tan 30^{\circ}=\frac{CE}{AE}$

$\frac{1}{\sqrt{3}}=\frac{\sqrt{3}CE}{40}$

$\implies CE = \frac{40}{3}$

Hence,

The height of the cloud above the lake = CE + ED

$=\frac{40}{3}+40=13.33+40 = 53.33\text{ meters}$

Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

$\to p(x\leq 2)=p(0)+p(1)+p(2)$

$=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227$

$\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}$

$\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx$

$=1-emp1-2|2.2\\\\=0.5971$

Amir stands on a balcony and throws a ball to his dog, who is at ground level.

Bumek [7]

Answer:

16 meters

Step-by-step explanation:

The height function is given by:

$h(x)=-(x+1)(x-7)\\h(x)=-(x^2+x-7x-7)\\h(x)=-x^2+6x+7$

The value of x, in seconds, for which the derivate of the height function is zero, is the time at which the maximum height occurs:

$\frac{dh(x)}{dx}= h'(x)=-2x+6=0\\x=3$

For x = 3 seconds, the height is:

$h(3)=-(3^2)+6*3+7\\h(3)=16\ m$

The maximum height that the ball will reach is 16 meters.
