Fifteen percent of the pigment in paint color A is black. Sixty percent of the pigment in paint color B is black. An unknown amount of paint color B is mixed with 40 ml of paint color A, resulting in a paint that contains 25% black pigment.
Which equation can be used to solve for x, the total amount of paint in the mixture of the two colors?
A. [tex]$0.15(40)+0.6 x=0.25(40+x)$[/tex]
B. [tex]$0.15(40)+0.6(x-40)=0.25(x)$[/tex]
C. [tex]$0.15(40)+0.6 x=0.25(40-x)$[/tex]
D. [tex]$0.15(40)+0.6(x+40)=0.25(x)$[/tex]
Answer (3)
Well, you could get the mass as m = g 0 ā G 0 ā ā ad then g 1 ā = m G 1 ā ā , where G 0 ā is the sea level weight, g 0 ā the sea level accel., g 1 ā the accel. above while G 1 ā the weight above.
Well, you could get the mass as m=\frac{G_0}{g_0} ad then g_1=\frac{G_1}{m}, where G_0 is the sea level weight, g_0 the sea level accel., g_1 the accel. above while G_1 the weight above ;
The mass of the object was calculated to be approximately 0.5205 kg using its weight at sea level. The acceleration due to gravity 1,000 km above sea level, where the object weighs 3.81 N, is approximately 7.32 m/sĀ². Thus, the gravitational force acting on the object in the spaceship is weaker than at sea level.
