Answer:

The tree is  6.36  meters tall.

Explanation:  Let AB is tree of height  h t = ?  and CD is Tonya  h g = 1.3  meter tall at  A C =  7 meters in front of tree . The shadow  C E = 1.8  meters long .  So two similar triangles are formed , one  Δ A E B and other  Δ C E D . So  A B C D = A E C E  or  h t h g = A E A C  or   h t h g = A C + C E  AC  or  h t  1.3 = 7 + 1.8 1.8  or  h t = 8.8 ⋅ 1.3 1.8 ≈ 6.36 ( 2 d p )m

The tree is  6.36  meter tall.

a diver is 19 meters below the surface of the water use an integer to represent how far the diver will need to travel to reach t
Basile [38]

Answer:

The diver need to travel 19 meter up to reach the surface

Step-by-step explanation:

* Lets explain how to solve the problem

- For any starting point the position at it is zero

- If the moving from the starting point is vertically, then the distance

 below the starting point is negative and above the starting point

 is positive

- If the moving from the starting point is horizontally, then the

 distance left to the starting point is negative and right to the

 starting point is positive

* Lets solve the problem

- A diver is 19 meters below the surface of the water

- Assume that the surface of the water is the zero position

∵ The diver is 19 meter below the surface of the water

∴ The diver is at the position -19

- The diver need to travel 19 meters to reach the surface of the water

∵ -19 + 19 = 0

∴ The diver need to travel 19 meter up to reach the surface

Tell whether the triangle with the given side lengths is a right triangle.<br> 10in., 24in., 26in.
ra1l [238]
Answer- Yes it is a right triangle.
You can use the Pythagorean Theorem.
( a^2 + b^ = c^2 ) and replace a with 10, b with 24, and c with 26 and the equation will be balanced on both sides.

(10^2 + 24^2 = 26^2)
(100 + 576 = 676 )

Can you guys please help. I really don't know how to solve this
Nonamiya [84]

The inequalities that can be used to represent this problem are x < 0 or x > 5. On the number line, you will want to place an open circle on both 0 and 5. The open circle signifies that x is not equal to these values, but is greater or less than. On the open circle on 0, draw an arrow pointing left, toward the negative values. On the open circle on 5, draw an arrow pointing right, toward the positive values.

Hope this helps!! :)
