A: 10,000 residents to 25 police officers
Step-by-step explanation:
400*25=10,000
Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)
1134.6x + 30634.2 = 1469.4x - 39673.8
334.8x = 70308
x = 210 mph
Answer:
x equals 10
Step-by-step explanation:
All triangles have 180 degrees
The bottom left angle is a right angle and is therefore 90°
That leaves us with x+8x=90°
9x=90°
x=10°
Answer:
2, 4 and 6 are consecutive even integers that fit the criterion.
Step-by-step explanation:
Model the problem as an equation
let a be first integer, b be second, c be third
8a = b+c+6
Since these are consecutive even integers:
b = a + 2
c = b + 2 = a + 4
Substitute these equivalents into the equation
8a = (a+2)+(a+4)+6
Combine like terms
8a = a+2+a+4+6
8a = 2a + 12
Isolate a
6a = 12 (divide both sides by 6)
a = 2
Sub a=2 into b=a+2 and c=a+4
b=a+2 = 2+2 = 4
b=4
c=a+4 = 2+4 = 6
c=6
