19.6 rounds to 20%
19.9 rounds to 20%
19.5 rounds to 20%
14.5 rounds to 15%
No the table would not be useful, 3 of the ingredients round to 20%
So C is the correct answer
Rewrite the fractions to have a common denominator
2/5 = 6/15
1/3 = 5/15
Add together: 6/15 + 5/15 = 11/15
Subtract from 1:
1-11/15 = 4/15
4/15 of them are ripe
Answer:
Step-by-step explanation:
you have a total of 5+7+4=16 marbles in the box.
5 are red
7 are white
4 are green
If you randomly select 1 marble out of the box, the probabilities are:
5/16 chance of being red
7/16 chance of being white
4/16 chance of being green
Given:
To find:
Draw a graph of a line that is perpendicular to the given line and passing through a given point.
Explanation:
As we know that relation between two slopes of perpendicular slopes of lines:
Slope of given line y = 4x + 1 is:
So, the slope of line perpendicular to given line is:
Also, so line equation that is perpendicular to given line is:
Also, the required line is passing thorugh given point (2, 3), i.e.,
So, line equation that is perpendicular to given line is:
The required graph of line is:
Answer:
The ratio of boys to girls is
The simplified ratio of boys to girls is
So the ratio of girls to total students is
The simplified ratio of girls to total students is
Step-by-step explanation:
Ratio of a to b:
The ratio of a to b is given by:
Boys to girls:
There are 16 boys and 20 girls.
So the ratio of boys to girls is
Both these numbers can be simplified by 4, 16/4 = 4, 20/4 = 5. So the simplified ratio of boys to girls is
Girls to total students
There are 20 girls and 20 + 16 = 36 total students.
So the ratio of girls to total students is
Both these numbers can be simplified by 4, 20/4 = 5, 36/4 = 9. So the simplified ratio of girls to total students is
