Answer: The tree was 27 feet tall
Step-by-step Explanation: First of all Sally was standing 30 feet away from the tree and she looks up at an angle of elevation of 38 degrees to the top of the tree. With this bit of information we can determine that a right angled triangle has been formed with the reference angle as 38 degrees, the side facing it as h (the height of the tree) and the adjacent side as 30. We shall apply the trigonometric ratio as follows;
Tan 38 = opposite/adjacent
Tan 38 = h/30
0.7813 = h/30
0.7813 x 30 = h
23.4 = h
We remember at this point that Sally’s eyes were 4 feet above the ground. What we have just calculated is the height of the tree from “4 feet above the ground” (where her eyes were). Hence the actual height of the tree is calculated as 23.4 plus 4 which gives us 27.4
Therefore the tree was 27 feet tall (approximately to the nearest foot)
If you would like to solve the inequality x - 8 > -3, you can do this using the following steps:
<span>x - 8 > -3
</span>x > -3 + 8
x > 5
The correct result would be x > 5.

An irrational numbers are numbers that cannot be expressed as simple fractions.
The square root of 37 is irrational.
Since it cannot be expressed as a simple fraction because if turned into a decimal
= 6.08276253
Answer = irrational.
Good Luck! :)

For the pizza that needs 1/3 of a block you know that with 1 block you can make 3 pizzas so if each block gives you 3 pizzas and you have 9 blocks then you would show 3 x 9 = 27 so you could make 27 pizzas
for the pizzas that need 1/5 you can make 5 pizzas with 1 block so same thing
5 x 9 = 45 so 45 pizzas
