The volume of a cube is 985cm3. Work out the length of its side rounded to 1 DP.

9.9 cm

Step-by-step explanation:

The volume of a cube is a³.

a³ = 985

The volume is already given. Take the cube root of both sides.

a = ∛985

a = 9.9497478956

Round the answer to 1 decimal place.

The side length is 9.9 centimeters.

9.9 cm

Step-by-step explanation:

Length = V^1/3

Length = 3√985

Length = 9.94975

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
