Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re

DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ $2 red= blue\ balloon$

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ $\frac{1}{2} \ white= blue\ balloon$

As above equation, we can understand that:

$2\ red= \frac{1}{2} \ white\ balloon$

multiplying both side by 2

⇒ $4\ red= white\ balloon$

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= $2+4+1= 7$

Now, checking how many number of times combination can we have in 49 balloon.

$\frac{49}{7}= 7 \ times$

Next, finding number of balloon in each color.

Red color= $4\times 7= 28\ balloon$

Blues color= $2\times 7= 14\ balloon$

White color= $1\times 7= 7\ balloon$

Answer:

14π or 43.98

Step-by-step explanation:

Area of the whole semi-circle is about 21π

Divide 42 into thirds and 1/3 is the diameter of the small semi-circle (14 in) now the area of the small semi circle is: 7π

The area of the shaded region is 14π or about 43.98

(this may be slightly off because I actually used π)
