Answer:
2.5
Step-by-step explanation:
1st Quartile (Q1): 1
2nd Quartile (Q2): 2
3rd Quartile (Q3): 3.5
IQR = Q3 - Q1 = 3.5 - 1 = 2.5
Answer:
Base = x = 18ft
Height = x - 4 = 14ft
Step-by-step explanation:
The formula for the area of A the triangle is given by the following equation:
1) A = (base * heigth)/(2)
From this problem, we know that
base = x and that the height is 4ft less than the base, so height = base - 4 = x - 4.
We also know that the area is 126ft², so A = 126 ft². Now we can replace these informations in equation 1).
126 = (x(x-4))/2
x² - 4x = 252
x² -4x - 252 = 0
The roots of this equation are x = 18 or x = -14. But we know that a triangle cannot have negative dimensions, so we use x = 18.
The base is x, so base = 18ft.
Height is 4ft less than the base, so height equals 18-4 = 14ft
Answer:
rectangle, square, circle
Step-by-step explanation:
Rectangle: length: 10 feet, Width: 50/10=5 feet
Square: length: 50/4=12.5 feet
Circle: 2pi(r)=50, radius=25/pi
7-foot
EXPLANAT
Given:
14 foot tree
8foot shadow
4foot shadow
Let h be the height of a tee that casts a 4 foot long shadow.
Using proportion;
14 foot = 8 ft shadow
h = 4 ft shadow
Cross - multiply
8h = 56
Divide both-side by 8
h = 7 foot.
Hence, the tree is 7-foot.
