Answer:

Ok so i hope this helps you.

There are 56 dogs when the number of cats is 140.

Step-by-step explanation:

The ratio of dogs to cats:

\frac{2}{5}

The other proportion:

\frac{x}{140}

\frac{2}{5} = \frac{x}{140}

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1

\frac{2}{5} * \frac{28}{28} = \frac{56}{140}

There are 56 dogs when the number of cats is 140.

Solve the equation for x, accurate to three decimal places: log3 (log2 x) = 1.
lesya692 [45]

Make both sides powers of 3:

3^{\log_3(\log_2x)}=3^1\implies\log_2x=3

Make both sides powers of 2:

2^{\log_2x}=2^3\implies x=8=8.000

Autumn measures the angle of elevation from the ground to the top of an 18-foot tall tree as 27°. To the nearest tenth of a foot
leonid [27]

Answer: she is 35.3 feet from the tree.

Step-by-step explanation:

Assuming her line of sight to the top of the tree is a straight line, then a right angle triangle is formed. The height of the tree, h represents the opposite side of the right angle triangle. Her distance, h from the tree represents the adjacent side of the right angle triangle. To determine h, we would apply the tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan 27 = 18/h

h = 18/tan27 = 18/0.51

h = 35.3 feet

worty [1.4K]

Answer:

22°

Step-by-step explanation:

Triangle KJL ≅ Triangle MJL (RHS)

[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]

we come up to the conclusion that 4x + 6 = 3x + 10

x = 4

∴angle KJL = 4(4) + 6 = 22°
