Height of another tree that cast a shadow which is 20ft long is 5 feet approximately
<h3><u>Solution:</u></h3>
Given that tree with a height of 4 ft casts a shadow 15ft long on the ground
Another tree that cast a shadow which is 20ft long
<em><u>To find: height of another tree</u></em>
We can solve this by setting up a ratio comparing the height of the tree to the height of the another tree and shadow of the tree to the shadow of the another tree

Let us assume,
Height of tree = 
Length of shadow of tree = 
Height of another tree = 
Length of shadow of another tree = 
Set up a proportion comparing the height of each object to the length of the shadow,


Substituting the values we get,

So the height of another tree is 5 feet approximately
Answer:
<h2> $430.90</h2>
Step-by-step explanation:
Given that the principal p= $290
rate r= 2.2% 2.2/100 =0.022
time t= 18years
by applying the expression

We have

Hence after 18years the money in the account will be $430.90
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C
Answer:

Step-by-step explanation:
We can start by finding the third side of the triangle/the side of the square using the Pythagorean Theorem:

In this case the side length of the square would be represented by the variable "c" as it is the hypotenuse:




Since the area of a square is the side length square then...

The square root and the squared cancel out giving us...

Answer: Yes, the highest side would be F
