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

Alex has 175 baseball cards.Rodney has 3 times as many baseball cards as Alex.How many fewer cards does Alex have than Rodney?
The difference between Rodney's and Alex's baseball cards is 350.
Alex has 350 fewer baseball cards than Rodney.
What is subtraction?Subtracting means to take away from a group or a number of things.
When we subtract, the number of things in the group reduces or becomes less.
We have,
The number of baseball cards Alex has:
= 175
The number of baseball cards Rodney has:
= 3 x 175
= 525
We need to find out how much Alex's cards are fewer than Rodney's cards so we find the difference between the number of cards between them.
The difference between Rodney's and Alex's baseball cards:
= 525 - 175
= 350
Thus Alex has 350 fewer baseball cards than Rodney.

A soda shop owner told his employee to add 2 full cups and 1/5 of a cup of syrup to each gallon of soda. If there were 4 gallons of soda, how much syrup would be needed? Show your work.
To find the amount of syrup, multiply the amount of syrup per gallon by the number of gallons of soda. In this case, this would be 2 1/5 cups and 4 gallons.
2 1/5 x 4
(Changing the mixed number 2 1/5 to an improper fraction!)
11/5 x 4/1 = 44/5
(Change back to a mixed number after multiplying!)
8 4/5 cups of syrup

Solve the equation. What is the value of x? x-6.8=356.3
To solve the equation x - 6.8 = 356.3, add 6.8 to both sides to isolate x, resulting in x = 363.1.
To solve the equation x - 6.8 = 356.3, we need to isolate the variable x. To do this, we can add 6.8 to both sides of the equation, effectively moving the 6.8 from the left side to the right.
Step-by-step:
Add 6.8 to both sides: x - 6.8 + 6.8 = 356.3 + 6.8Simplify both sides: x = 363.1The value of x is 363.1.

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
