The following figure is made of six semicircles with the same diameter, and of four congruent equilateral triangles represented
Oxana [17]

6 semicircles = 3 circles

The formula of the area of a equilateral triangle:

A_\triangle=\dfrac{a^2\sqrt3}{4}

We have a = |AE| = 3cm. Substitute:

A_\triangle=\dfrac{3^2\sqrt3}{4}=\dfrac{9\sqrt3}{4}\ cm^2

The formula of the area of a circle:

A_O=\pi r^2

We have 2r = |AE| =3cm → r = 1.5cm. Substitute:

A_O=\pi\cdot1.5^2=2.25\pi\ cm^2

The area of the figure:

A=4A_\triangle+3A_O\\\\A=4\cdot\dfrac{9\sqrt3}{4}+3\cdot2.25\pi=9\sqrt3+6.75\pi=6\dfrac{3}{4}\pi+9\sqrt3\\\\=\dfrac{27}{4}\pi+\dfrac{36\sqrt3}{4}=\dfrac{9}{4}\cdot3\pi+\dfrac{9}{4}\cdot4\sqrt3=\dfrac{9}{4}(3\pi+4\sqrt3)\ cm^2

Which graph shows that Cindy reads about 3/4 of the time while riding in the car?
wolverine [178]

The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.

<h3>What is Unit Rate?</h3>

Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.

Unite rate (k) = x/y.

In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.

Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.

Richard, Angad and Paul share £108 in a ratio 2:3:1. How much money does each person get?
Natasha2012 [34]

Answer:

Step-by-step explanation:

If R, A, and P all share 108 pounds in the ratio of 2 to 3 to 1, then

2x + 3x + 1x = 108 and

6x = 108 so

x = 18.

R holds the ratio of 2x, so he gets 2(18) which is 36;

A holds the ratio of 3x, so he gets 3(18) which is 54;

P holds the ratio of 1x, so he gets 1(18) which is 18.

36 + 54 + 18 better equal 108...and it does!
