Answer:

AC = 52.8

Step-by-step explanation:

33/20 = 1.65

12*1.65 = 19.8

BA = 19.8

CB + BA = AC

33 + 19.8 = 52.8

Answer:

AC = 52.8

Step-by-step explanation:

Since BE is parallel to CD and intersects the 2 sides of the triangle then it divides those sides proportionally, that is

\frac{BC}{AB} = \frac{DE}{AE}, substituting values

\frac{33}{AB } = \frac{20}{12} ( cross-  multiply )

20AB = 396 ( divide both sides by 20 )

AB = 19.8

Thus

AC = AB + BC = 19.8 + 33 = 52.8

The ratio of height : shadow =44/1313

Therefore height of the tree,x=3434*(44/1313)
=115.08 ft

If you meant 13 and 34 as the length of shadows respectively, then also x=115.08 ft

Match the concept with its definition and characteristics. i. A set of instructions (codes) that perform a specific task. ii. A
kogti [31]

First definition matches with expression, second matches with equation ,third matches with algorithm and fourth matches with equation.

Given  four definitions of equation, expression, algorithm but mixed.

We have to match the definitions with appropriate term.

We know that expression is a combination of numbers, symbols, fraction, coefficients, indeterminants mostly not found in equal to form. It exhibits a behaviour only.

Algorithm is a computer programming to do a specific task in a predetermined way.

Equation is a relationship between two variables expressed in equal to form. In this we have to put the value of variables and the equation gives us a value.

Hence  First definition matches with expression, second matches with equation ,third matches with algorithm and fourth matches with equation.

The mean of the data is 11

now we find the difference between the mean and each number
1, 2, 3, 0.5, 0.25, 1.25, 1. 

now we square the numbers 
1, 4, 9, 0.25, 0.0625, 1.

now we find the mean of the new numbers
which is 2.1875

2.1875 is your standard deviation.
