Answer:

The value of 2 in 2000 is 10 times greater than the value of 2 in 200

Step-by-step explanation:

from the value of 2 in 200 to reach 2000, it takes 10 times as much because we're moving only one place (which is the thousand's digit).

Answer:

a) $p = 88\,cm$ , b) $p = 24\,cm$ , c) $p \approx 25.424\,m$ , d) $p \approx 39.368\,cm$

Step-by-step explanation:

a) The perimeter is the sum of the three sides of the internal square and the remaining sides of the external rectangle, that is:

$p = 3\times 8\,cm + 2\times 4\,cm +2\times 20\,cm + 16\,cm$

$p = 88\,cm$

b) The perimeter is the sum of the two sides of the internal triangle and the remaining sides of the external rectangle, that is:

$p = 2\times 4\,cm + 2\times 6\,cm + 4\,cm$

$p = 24\,cm$

c) The perimeter is the sum of the two sides of the circular section and the three sides of the lower rectangle, that is:

$p = \frac{\pi}{2}\times 6\,cm + 8\,cm + 6\,cm + 2\,cm$

$p \approx 25.424\,m$

d) The perimeter is the sum of the external sides of the triangle and rectangle, that is:

$p = 10\,cm + 12\,cm + 12\,cm + 12\,cm - \sqrt{(12\,cm)^{2}-(10\,cm)^{2}}$

$p \approx 39.368\,cm$

A florist has 45 tulips in his shop. 20% of the tulips are yellow. How many tulips are yellow?

EastWind [94]

Multiply 45 by 1/5, or 0.2, and you will get an answer of 9, which is the amount of tulips that were yellow. You will know that you need to multiply 45 by either 1/5 or 0.2 because you can make a fraction 20/100 and simplify it to 1/5, or you can move the decimal point in 20.% two times to the left getting the decimal to divide the amount of tulips by
