When two lines cross like this, sum of measures of opposite angles is 180.
this means that:
measure angle AEC + measure angle BED = 180
4x-40 + x+50 = 180
5x +10 = 180
5x = 170
x = 34
therefore:
measure angle AEC = 4x-40 = 4(34)-40 = 96
measure angle BED = x+50 = 34+50 = 84

What is the constant of proportionality in the table below?

kenny6666 [7]

Answer: $\dfrac{2}{5}$

Step-by-step explanation:

The constant of proportionality 'k' between two variables ( one independent and one dependent ) is given by :-

$k=\dfrac{\text{Value of dependent variable}}{\text{Value of independent variable}}$

In the given table, independent variable = Days

Dependent variable = Total Miles

From first row, Days = 3

Total Miles = $1\dfrac{1}{5}=\dfrac{6}{5}$

Then, the constant of proportionality in the table

$k=\dfrac{\dfrac{6}{5}}{3}=\dfrac{6}{5\times3}=\dfrac{2}{5}$

Hence, the constant of proportionality in the table is $\dfrac{2}{5}$ .

There is a light post that is 9 feet tall that casts a shadow that is 6 feet long. At the same time, there is a tree that casts

Salsk061 [2.6K]

Answer:

The height of the tree is 21 ft

Step-by-step explanation:

we know that

A light post that is 9 feet tall that casts a shadow that is 6 feet long

so

by proportion

Find out the the height of the tree if a tree that casts a shadow that is 14 feet long

Let

x ----> the height of the tree

$\frac{9}{6}=\frac{x}{14}\\\\x=9*14/6\\\\x=21\ ft$

therefore

The height of the tree is 21 ft

Answer:

She has a 4.16667% chance of having to go those days so my guess would be 4/25 (B)

Step-by-step explination

You add 2 and 4 and get 6. divide 25 by 6 then you get the answer I stated before and I rounded down.
