Answer:
0.9 yd³
Step-by-step explanation:
Information given:
Length = 18 ft
Width = 1.5 ft
Height = 1 ft
What to find/do:
First, convert the measurement from feet to yards. (3 ft = 1 yard)
Length = 18 ft = 6 yd
Width = 1.5 ft = 0.5 yd
Height = 1 ft = 0.3 yd
Next, find the volume of the shape given. The volume would give us the amount of concrete to use in yards.
Formula for volume = L*W*H
Plug in the values into the formula
V = 6*0.5*0.3 = 0.9 yd³
0.9 cubic yard of concrete must be ordered to pour on the given section.
Area of the volume
The best and most correct answer among the choices provided by the question is the fourth choice "d=square root of (x^2+x^1)+(y^2-y^1)^2"

Answer:
Therefore, the the world's predicted population in the year 2020 is 7,911×10^6 people.
Step-by-step explanation:
Given:
P₀ = 5,642×10^6 people,
i = 1.3% = 0.013 per year,
n = 2020 - 1994 = 26 years,
We get:
Pn = P₀ e^(i.n)
. . .= 5,642×10^6×e^(0.013×26)
. . .= 7,911×10^6 people
Answer:
greatest - romania; least - us; proof below
Step-by-step explanation:
to answer this question we must first find all the population densities by dividing the population by the area
for the us
272648000/9364520 = 29.115
for romania
22609000/237391 = 95.2394994
for ghana
18339000/237533 = 77.2061145
this means that the us has the lowest population density
this also means that romania has the highest population density
