Work out the volume of a cube with length 6.5cm. Give answer to 3 significant figures

265

Step-by-step explanation:

It's a cube, so all sides are the same, so 6.5 x 6.5 x 6.5

This equals 264.625. They want 3 significant figures, so u round to the nearest whole number. Significant numbers are whole numbers. This becomes, 265.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
