Answer:
The ratio of the number of boys to the number of girls in the class 1 to 2 or 1/2.
Step-by-step explanation:
Consider the provided information.
Let g is number of girls, and b is number of boys.
The total number of students is b + g.
It is given that, In a certain English class, 1/4 of the number of girls is equal to 1/6 of the total number of students.

Solve the above equation.




Hence, the ratio of the number of boys to the number of girls in the class 1 to 2 or 1/2.
Any number as the denominator and 0 as the numerator can be replaced in the place of 0.
Ten and seventy-three hundredths
9514 1404 393
Answer:
16.8°
Step-by-step explanation:
The Law of Cosines can be rearranged to give the angle measure.
angle Q = arccos((p² +r² -q²)/(2pr))
angle Q = arccos((690² +450² -290²)/(2×690×450))
angle Q = arccos(594500/621000) ≈ 16.7985°
The measure of angle Q is about 16.8°.
