Answer:
A
Step-by-step explanation:
To find the value you can just find 12% of each number (trial and error), until one of them gives you 90 as an answer:
A) 750
750 * 0.12 = 90
B) 1080
1080 * 0.12 = 129.6
C) 360
360 * 0.12 = 43.2
D) 1168
1168 * 0.12 = 140.16
This tells you that 90 is 12% of the 750, and that is why it is your answer
I hope this helps!
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
Answer:
Monique made an error when writing the factored expression.
Correct factored
expression=4x(1+4y)
Step-by-step explanation:
factoring the expression 4 x + 16 x y.
Factors of 4x: 1, 2, 4, x
Factors of 16xy: 1, 2, 4, 8, 16, x, y
GCF: 4x
Factored expression: 4 x (0 + 4 y)
Monique made an error when writing the factored expression.
The correct factored expression should be:
4x+16xy
=4x(1+4y)
Contrary to 4x(0+4y)
Correct factored
expression=4x(1+4y)
Answer:
350km
Step-by-step explanation:
If a map has a scale of 1: 500000, then 1 cm on the map is 500000 cm
So 7 cm on the map is 35000000 cm = 350 km
Answer:
yes because when you multiply 3000 by 10 that gives you a total of 30000 that you paid off
