Answer:
2/9
Step-by-step explanation:
The question asks to calculate the number of boys in a group who has brown eyes given the fraction of the boys having the brown eyes.
To do this, we can take any arbitrary value for the total number of students in the math club. Let’s say this is 360 students.
Now, we are told that half of these number are boys. The total number of boys is thus 180 boys. Also, we are made to know that 4/9 of these boys have brown eyes. This means 4/9 of 180 boys have brown eyes. This is numerically equal to 4/9 * 180 = 80 boys.
Hence, the fraction of the math club with brown eyes is 80/360 = 2/9
Answer:
I think that the answer is 25,180.
Step-by-step explanation:
9 3/4 acres in 3 3/8 days = 9 6/8 acres in 3 3/8 days
(72 + 6)/8 = 78/8
(24 + 3)/8 = 27/8
78/8 divided by 27/8 = 78/27 = 26/9 or 2 8/9 acres/day
Answer: 30 inches.
Step-by-step explanation:
We need to use the formula for calculate the perimeter of a rectangle. This is:
Where "l" is the length and "w" is the width.
In this case, we know that the lenght and the width of this rectangle are:
Therefore, substituting values into the formula, we get that the perimeter of this rectangle is:
<em>a = 85 10cent coins</em>
<em>b = 117 20cent coins</em>
- Step-by-step explanation:
<em>a = 10c coins</em>
<em>b = 20c coins</em>
<em>$31.90 = c3190</em>
<em>a + b = 202 => a = 202 - b</em>
<em>10a + 20b = 3190</em>
<em>10(202 - b) + 20b = 3190</em>
<em>2020 - 10b + 20b = 3190</em>
<em>10b = 3190 - 2020</em>
<em>10b = 1170</em>
<em>b = 117 (20cent coins)</em>
<em>a = 202 - 117</em>
<em>= 85 (10cent coins)</em>
