Answer:

The wide of river is $50\ ft$

Step-by-step explanation:

In this problem we know that

Triangles DEG and DEF are congruent by ASA (Angle-Side-Angle) Congruence

therefore

EG=EF

$EG=20*(2\frac{1}{2})=20*\frac{5}{2}=50\ ft$

Find x using completing the square method x^2+16n+28 = 0

Nezavi [6.7K]

Answer:

x=√−16n−28 or x=−√−16n−28

Step-by-step explanation:

Step 1: Add -16n to both sides.

x2+16n+28+−16n=0+−16n

x2+28=−16n

Step 2: Add -28 to both sides.

x2+28+−28=−16n+−28

x2=−16n−28

Step 3: Take square root.

x=√−16n−28 or x=−√−16n−28

Write an equation to represent the following: Three consecutive integers add up to 11 more than the smallest.

mr Goodwill [35]

Answer:

Step-by-step explanation:

First we have to assume the smallest integer.

Let,

the smallest integer is x

So, the other two integers are-

x+1 and x+2

Now,

the sum of these 3 integers is greater than smallest integer by 11

So, we get

x+(x+1)+(x+2) =x+11

This is the required equation.

The dot plots show rainfall total for several spring storms in highlands areas an lowlands areas what is the median rainfall for

tankabanditka [31]

*See attached picture showing the dot plots referred to

Answer:

16mm

Step-by-step Explanation:

Given the dot plot showing rainfall for Highlands storms, we can find out the median rainfall for Highlands storms by mere observing the dot plot and locating where the middle value falls within the data set that is represented on the dot plot.

Thus, we have 44 data sets that is being represented on the plot, with one dot representing one data set for rainfall. This means, since the total number of data set is even, our median lies between the 22nd and the 23rd dot or data set that is being plotted.

From the dot plot for Highlands, the 22nd and 23rd dots are 16 and 16 respectively.

Therefore, median rainfall for Highland storms = (16 + 16) ÷ 2 = 16.
