Answer:
The distance between two cities is 70 km.
Step-by-step explanation:
Given that,
The distance between two cities on a map is 3.5 centimeters.
It is also mentioned that the map uses a scale in which 1 centimeter represents 20 kilometers.
We need to find the actual distance between these two cities in kilometers.
1 cm = 20 km
3.5 cm = (3.5 × 20) km
= 70 km
Hence, the distance between two cities is 70 km.
Answer:
C. (3x+12) + x = 180
Step-by-step explanation:
the 2 angles create a straight line which is 180 degrees, so (3x+12) + x = 180
Answer: d=sqrt(41) =6.4031
Step-by-step explanation:
We know that the distance between the two points (x 1 ,y 1 ) and (x 2 ,y 2
) is
d= sqrt((x2-x1)^2 +(y2-y1)^2 )
as given
x1=2 ,x2=6 ,y1=3 ,y2=8
d=sqrt((6-2)^2+(8-3)^2 )
d= sqrt((4)^2+(5)^2
d=sqrt(16+25)
d=sqrt(41) =6.4031
Answer: x > 5
Explanation: First we want to look at our variable and ask ourselves what's happening to it. Since 2 is being subtracted from 9x, we always undo addition and subtraction first so we add 2 to both sides.
That gives us 9x > 45.
Now we need to undo multiplication and division. Since 9 is being multiplied by <em>x</em>, to get <em>x</em> by itself, we need to divide by 9 on the left side of the inequality. If we divide by 9 on the left side, we must also divide by 9 on the right side.
This leaves us with <em>x > 5</em> which is the solution to this inequality.
Answer:
20 square units
Step-by-step explanation:
Area of a parallelogram is calculated with the following formula:
b*h (b: base, h: height)
5*4 = 20 square units
