Math question 3 and 4

3.) B = 72 m^2

4.) V = 564 m^3

Step-by-step explanation:

3.) Find the area of the base:

The base is shaped like a triangle so we need to use this formula: A = bh/2

A = bh/2

A = (9)16/2

A = 144/2

A = 72

The base measures 72 square meters.

4.) Find the volume of the pyramid:

V = Bh/3

V = (72)23.5/3

The height is listed as 23 1/2, but it can be written as a decimal as shown above.

V = 1,692/3

V = 564

The volume is 564 cubic meters.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
