If a man had black hair and blue eyes and the woman had blond hair blue eyes can the child come out with brown eyes blond hair if the grandmother had brown eyes?
Blue eyes are a recessive trait. If at least one of the parents had a blue/hazel eyes with a mixture of blue and brown, then the couple's offspring could have brown eyes. If both parents had solid blue eyes, neither would have the dominant brown gene to pass to the baby, and it would have blue eyes, regardless of the grandmother's eye color.

In a class of 150 students 55 speak En glish 85 speak Telugu and 30 speak neither English nor Telugun How many speak both English and Telugu?
55 students speak English, 85 students speak Telugu, and 30 students speak neither. To find out how many students speak both English and Telugu, we can use the formula: Total = English + Telugu - Both + Neither. Plugging in the values: 150 = 55 + 85 - Both + 30. Solving for Both, we get: Both = 10 students.

There are 10 students receiving honors credit in a class. This number is exactly 20 percent of the total number of students in the class. How many students are in the class?
Here are 10 students getting honors credits in a class, and they make up 20% of the class. How do we find the number of students in the class? Let's look. We have a class, and 20% of the class are getting honors credit, and that turns out to be 10 students. Now we can generate a formula that we can use to discover our answer. Let's assign letters to the things we know or are finding out. Nclass = number of students in the class. Nhonors = number of honors students in the class. And Nhonors = 10 students. Nclass x 20% = 10 students 20% = 20/100ths (because % = hundredths) or 0.20 or just 0.2 for simplicity. Nclass x .2 = 10 students Now divide both sides by .2 so the .2 will cancel out (or drop out) on the left side of the equation and we'll have isolated the answer we are looking for, which is Nclass. Nclass = 10 students divided by .2 Nclass = 10/.2 students = 50 students There are 50 students in the class. As .2 equals 2/10 or 1/5, we can find 1/5th of 50 just by thinking about it to check our work. And 1/5th of 50 equals 10, which is in agreement with the information we were given in the problem.
