Suppose that you measure a pen to be 10.5 cm long. convert this to meters. express your answer in meters.

Given: Length a pen = 10.5 cm.

We need to convert this value in meters.

We know,  100 cm=1 meter.

On dividing both sides by 100.

On simplifying,

1 cm= 0.01 meter.

In order to find the value of 10.5 cm in meters, we need to multiply 10.5 by 0.01 because in meter form 1 cm equals 0.01 m.

On multiplying 10.5 by 0.01, we get

10.5 × 0.01 = 0.105 meter.

Therefore, 10.5cm = 0.105 merter.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
