I'm thinking you would have to add the probabilities that you choose a boy with you choose someone in the science club minus a boy in the science club. You can't count these people twice. I'm getting 59% (11+10-2)/32

Need a little help with one please

Pani-rosa [81]

Answer:

That would be the side-side-side (SSS) postulate, which states that if all the sides of a triangle are in a fixed ratio to all the corresponding sides of another triangle, then the two triangles are said to be congruent.

Step-by-step explanation:

Looking at triangles ABC and DEF, we notice that:

$\frac{AB}{DE} = \frac{AC}{DF}=\frac{BC}{EF}$

since

$\frac{3}{18} = \frac{6}{36}=\frac{7}{42}=\frac{1}{6}$

Let me know if you have further questions.

The length of a rectangle is increasing at a rate of 6 cm/s and its width is increasing at a rate of 5 cm/s. When the length is

Rudiy27

Answer:

Area of the rectangle is increasing with the rate of 84 cm/s.

Step-by-step explanation:

Let l represents the length, w represents width, t represents time ( in seconds ) and A represents the area of the triangle,

Given,

$\frac{dl}{dt}=6\text{ cm per second}$

$\frac{dw}{dt}=5\text{ cm per second}$

Also, l = 12 cm and w = 4 cm,

We know that,

A = l × w,

Differentiating with respect to t,

$\frac{dA}{dt}=\frac{d}{dt}(l\times w)$

$=l\times \frac{dw}{dt}+w\times \frac{dl}{dt}$

By substituting the values,

$\frac{dA}{dt}=12\times 5+4\times 6$

$=60+24$

$=84$

Hence, the area of the rectangle is increasing with the rate of 84 cm/s.

If a person stands 40 ft from a tree and the angle of elevation made from their eyes (5 ft above the ground) to the top of the t

goldenfox [79]

Using the given information, the height of the tree is 48 ft

<h3>Trigonometry </h3>

From the question, we are to determine the height of the tree

In the given diagram, the height of the tree is (x + 5) feet

First, we will determine the value of x

tan 47° = x / 40

x = 40 × tan47°

x = 42.89 ft

∴ The height of the tree = (42.89 + 5) ft

Height of the tree = 47.89 ft

Height of the tree ≈ 48 ft

Hence, the height of the tree is 48 ft.
