Step-by-step explanation:

Take your given equation

w+w+w+b+b+b+b

There are 3 w's and 4 b's

Combine like terms

w+w+w=3w

b+b+b+b=4b

3w+4b

R+q-r; use q=6,and r=2

Anastasy [175]

Answer:

so you would replace all r with 2 which is 2+q-2

then replace the q with 6 so it would be: r+6-r

combined both of these to get

2+6-2

which would equal to 6

add the 2 and the 6 to get 8

then subtract 2 to get 6

A skier is on the top of a 350 meter tall mountain looking down at a tree. The direct path from the tree to the skier is 505 met

denpristay [2]

Answer:

$43.87^{\circ}$

Step-by-step explanation:

We are given that

Height of mountain=350 m

Distance from the tree to the skier=505 m

We have to find the angle of depression from where the skier is standing to the base of the tree.

In triangle ABC

$\frac{AB}{AC}=sin\theta$

By using the formula

$\frac{Perpendicular\;side}{Hypotenuse}=sin\theta$

$\frac{350}{505}=sin\theta$

$sin^{-1}(\frac{350}{505})=\theta$

$\theta=43.87^{\circ}$

Hence, the angle of depression from where the skier is standing to the base of the tree= $43.87^{\circ}$
