Answer:

3925 units²

Step-by-step explanation:

area of larger circle = πr² = (3.14)(250²) = 196,250

area of smaller circle = πr² = (3.14)(200²) = 125,600

area of full donut = 196,250 - 125,600 = 70,650

20/360 = 1/18 of full donut

1/18(70,650) = 3925 units²

The losing candidate in a mayoral election received 10,200 votes, which represented 30% of all votes cast in the election.
ElenaW [278]

well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.

B)

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x

A)

Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.

HELP ME (How many cubes with side length 1/2 cm does it take to fill the prism
Natalija [7]

answer:

6

step-by-step explanation:

  • for this you would find the volume and then divide by 1/2

v = l x w x h

v = (1)(2)(3/2)

v = 3

  • now, divide

3 ÷ 1/2 = 6

  • therefore, it will take 6 half cubes to fill up the container
