Answer:
Okay, so we know a number of students and the amount of girls as a bracket. So what we have to do now is multiply them with each other.
28 *4/7 = 16
So there are 16 girls in Mr. Chang´s class.
You can also determine the boys by - the students with the girls:
28-16=12 boys

Answer: 9.73 lb each chair
Step-by-step explanation:
You substract the weight of the table alone from the full weight:
235.68 - 157.84=77.84

77.84/8= 9.73 the weight of each individual chair
3 x 1/6
Simplify,
3/6 = 1/2
So, = 1/2

x=3y+8 ---> y=
y=
Answer:
x = 20.8
y = 22.3
Step-by-step explanation:
tan(21) = 8/x
or, x = 8/tan(21)
or, x = 20.8 (rounded to the nearest tenth)
sin(21) = 8/y
or, y = 8/sin(21)
or, y = 22.3 (rounded to the nearest tenth)
