Answer:

Lowest grade is 70.

Step-by-step explanation:

To have an average of 80 the total score is 4 * 80 = 320.

So the score for the next test must be 320 - (85 + 74 + 91)

= 70.

Answer:

The density of cube is 6.17959 $\frac{g}{cm^{3} }$

Step-by-step explanation:

The density is given by ration of a mass of body and volume occupied by a body.

$\rho = \frac{m}{V}$

Where,

$\rho$ is density.

m is mass of a body

V is the volume of a body

Given that one side of the cube is 0.53cm

Hence, the volume of a body is V= $0.53^{3}$ =0.148877 $cm^{3}$

Now, the Density of the cube will be

$\rho = \frac{m}{V}$

$\rho = \frac{0.92}{0.148877}$

$\rho =6.17959$

Thus, The density of cube is 6.17959 $\frac{g}{cm^{3} }$

Answer:

a = c - 3b/2

Step-by-step explanation:

2a + 3b - 3b = c - 3b

2a = c - 3b

2a/2 = c/2 - 3b/2

therefore your answer is a = c - 3b/2
