La of sine:
sinC/c = sinB/b==> sin 37°/8 = sin B/12 ==> sin B = 0.903
arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then
sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
Answer: A
Step-by-step explanation:
This is because...
1st. Simplify both sides of the equation (distribute the 4 and combine like terms)
6 + -x = 20 + 4x + -4 (distributed 4)
-x + 6 = 4x + 16 (combined like terms)
2nd. Subtract 4x from both sides.
3rd. Subtract 6 from both sides.
4th. Divide both sides by -5.
Answer:
percentage of seventh graders on the team is 20%
Step-by-step explanation:
given data
total girl = 25
soccer team = 5
to find out
percentage of seventh graders on the team with two different way
solution
we first make here a tape diagram
there in begin by divide the tape diagram into 5 equal part
and Each part represent 5 girls
so divide the 100% into 5 equal sections as show in figure below
and
another way is
percentage of seventh graders on the team is =
× 100%
percentage of seventh graders on the team is 20%
