Answer:
$19,260
Step-by-step explanation:
6,000 * 7% = 420
6,000 + 420 = 6,420
6,420 * 3 = 19,260

Answer:
Greatest: Denmark
Least: U.S.
Step-by-step explanation:
The population density is calculated by dividing the population by the area.
U.S.
Population density = 272,648,000/9,364,520 = 29.1
Denmark
Population density = 5,248,000/42,077 = 124.7
Ghana
Population density = 18,339,000/237,533 = 77.2
Greatest: Denmark
Least: U.S.
Answer:
x = students
y = adults
Linear Systems of Equations :
x + y = 937
0.75x + 2y = 1,109
Step-by-step explanation:
Step 1 : eliminate one of the variables
x + y = 937
0.75x + 2y = 1,109
-2(x + y = 937) = -2x - 2y = -1874
-2x - 2y = -1874
0.75x + 2y = 1109
We can eliminate y since -2y + 2y = 0
Step 2: Find x number of students.
-2x = -1874
+0.75x = 1109
____________
-1.25x = -765
____________ = 612 students attended
-1.25
937 - 612 = 325 adults
Check Answer :
612 x 0.75 = $459
325 x 2 = $650
$650 + $459 = $1,109
Therefore, there will be 612 students attending and 325 adults.
B) 6
area of square = s^2
s^2 = 36
s = 6
11.5, when rounded to the nearest tenth the answer was 11.468 but we need to round and 6 is 5 and higher so the 4 would become a 5. The answer is 11.5
