Answer:
1. 0.8 cm
2. 1.6 cm
Step-by-step explanation:
1.
The scale for 2nd map is 1 cm to 50 km, that means "1 cm on map" is "50 km in real life".
We already know distance from Cleveland to Cincinnati is 40 km, which is less than 50, so we know the distance on map would be less than 1 cm.
So we set up ratio and figure out (let x be distance on map from Cleveland to Cincinnati):
![\frac{1}{50}=\frac{x}{40}\\50x=40\\x=\frac{40}{50}\\x=0.8](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B50%7D%3D%5Cfrac%7Bx%7D%7B40%7D%5C%5C50x%3D40%5C%5Cx%3D%5Cfrac%7B40%7D%7B50%7D%5C%5Cx%3D0.8)
Hene, 0.8 centimeters would be the distance in 2nd map
2.
A scale of 1:50 means 1 cm equal 50 cm
So, 0.8m would be
0.8 * 100 = 80 cm
Hence, 80 cm would be represented by 80/50 on the map, that is:
![\frac{80}{50}=1.6](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B50%7D%3D1.6)
That is 1.6 centimeters
pacey = x
alex = 2x
paul = 3x
x + 2x + 3x = 342
6x =342
x = 342 / 6
x = 57
Pacey's fish = 57 pounds
Alex's fish = 57*2 = 114 pounds
Pauls fish = 57*3 = 171 pounds
Answer:
Density is defined as:
Density = mass/volume.
We know that:
For liquid A:
Density = 70kg/m^3
Mass = 1400kg
Then the volume is:
Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3
For liquid B:
Density = 280 kg/m^3
Volume = 30m^3
We can find the mass of liquid B as:
mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg
We know that liquid C is a mixture of liquid A and B.
Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:
Mass of liquid C = 1400kg + 8400kg = 9800kg
The same happens for the volume, then:
Volume of liquid C = 30m^3 + 20m^3 = 50m^3
Then the density of liquid C is:
Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3
