Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles
The value of 54% as a fraction is 27/50.
The value of 0.22 as a fraction is 11/50.
<h3>What is a fraction?</h3>
A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.
In this case 54% will be:
= 54 / 100
= 27 / 50
Also, the value of 0.22 will be:
= 22 / 100
= 11 / 50

Answer:
30.89cm³
Step-by-step explanation:
Given that:
Side length, s of square = 12cm
Area of square = s² = 12² = 144cm²
Since the circle touches the edge of tbe square, then the diameter of the circle = side length of square = 12 cm
Area of a circle = πr²
Radius, r = diameter / 2 = 12/2 = 6cm
A = 3.142 * 6^2
A = 3.142 * 36
A = 113.112 cm²
Area of shaded portion = area of square - area of circle
= 144cm² - 113.112cm³
= 30.89cm³
