The diagram shows a logo made from 3 circles. Each circle has a centre 0. daisy says exactly 1/3 of the circle is shaded. is dai

marusya05 [52]

Daisy is not correct. The shaded part is 3/50 that of the whole circle.

<h3>Is Daisy correct?</h3>

In order to determine if Daisy is correct, the area of the circle and the area of the shaded part has to be determined.

Area of the circle = = πr²

Where :

π = pi = 22/7

r = radius = 4 + 3 + 3 = 10

10²π = 100π

Area of the shaded part = 3²π = 9π

Ratio of the areas = 9π / 100π

Before the election, you want to determine the number of possible president/vice-president combinations for the sorority you bel

vichka [17]

Solution: We have to choose two positions president and vice president from eight people. So, we need to use the Permutations formula in order to find the possible number of combinations.

The number of possible combinations is:

8P2 $=\frac{8!}{(8-2)!}$

$=\frac{8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1}$

$=\frac{40320}{720}$

$=56$

Therefore the possible number of combination to select two positions from 8 people is 56

Polygon C has an area of 7 square units. Jennie drew a scaled version of Polygon C and labeled it Polygon D. Polygon D has an ar

dem82 [27]

The ratio between Area of D and Area of C is 28:7.

That means the simplified version is 1:4.

From our ratio, we can derive that the scale factor is 4.
