a road sign casts a shadow 14 meters long while a nearby tree casts a shadow 27.8 meters long. if the road sign in 3.5 meters high how tall is the tree
The height of the tree is 6.95 m
What are similar triangles?Two triangles are said to be similar triangles if their corresponding sides are in equal ratio and corresponding angles are congruent.
Given that, a road sign casts a shadow 14 meters long while a nearby tree casts a shadow 27.8 meters long and the road sign in 3.5 meters
Since, both the figures will be the similar triangles,
Then, by definition of similar triangles,
Therefore,
Let the height of the tree be x,
3.5 / 14 = x / 27.8
x = 6.95
Hence, the height of the tree is 6.95 m

Answer: Each friend will get 0.527 pound of grapes.
Step-by-step explanation:
We are given that Joe bought 5.8 pounds of grapes to have as a snack with his 10 friends.
Total persons including Joe = 10+1= 11
If he shares his grapes evenly, then by division operation , we have
Number of pounds of grapes will each of his friends get will be
[tex]5.8\div11\approx0.527[/tex] pounds
Therefore, each friend will get 0.527 pounds of grapes.

Which graph shows y=1/2⌈x⌉ ?
Answer:
Your answer is B
Step-by-step explanation:
The graph that shows y=1/2⌈x⌉ is Graph B
How to determine the graphThe function y=1/2⌈x⌉ represents the graph of y in terms of x where [x] denotes the ceiling function that rounds x up to the nearest integer.
The graph of y=1/2⌈x⌉ consists of a series of horizontal line segments with a slope of 1/2 at integer values of x, jumping to the next integer value as x increases .
Visually, this graph would show horizontal line segments positioned at integer value of x, with each segment having a slope of 1/2 and stepping up or down to the next integer value of y

For every 240 days of milking, cow's milk production decreases by 2.
Which shows the average change in cow's production?
A. -120 gallons per day
B. - (1/120) gallons per day
C. 1/20 gallons per day.
D. 120 gallons per day.
The solution is Option B.
The slope / average change in cow's production is m = - 1/120 gallons per day
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of the equation A is
For every 240 days of milking, cow's milk production decreases by 2
So , the value of y = 2 gallons
The value of x = 240 days
Now , the slope of the equation is given as
Slope m = y/x
And , The slope of a line is a measure of its steepness, slope is calculated as "rise over run" or change in y divided by change in x
Substituting the values in the equation , we get
Slope m = 2/240
Slope m = 1/120
Since the cow's milk production decreases by 2 , the slope will be negative
So , slope m = -1/120 gallons / day
Hence , the average change in cow's production is -1/120 gallons / day
