A grade school has 45 students who walk to school and 150 students who ride the bus. The other 50 students are driven to school. Which ratio shows the number of students who walk to the total number of students in the school?

the ratio is 9 ÷ 49

Step-by-step explanation:

The computation of the ratio of the number of students who walk to the total number of students is shown below:

= 45 students ÷ ( 45 + 150 + 50)

= 45  students ÷ 245 students

= 9 ÷ 49

Hence, the ratio is 9 ÷ 49

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

2y+y=5

add 2y and y
