Opposite interior angles are equal, so
4x - 10 = 2x + 20
2x - 10 = 20
2x = 30
x = 15
Yes. They are both right.
Answer:
V = 113.04
Step-by-step explanation:
Volume of a sphere:
V = 4/3πr³
V = 4/3(3.14)3³
V = 4/3(3.14)27
V = 113.04
Answer:
0.36
Step-by-step explanation:
Percentage of boys = 60%
Percentage of girls = 100 - 60 = 40%
Percentage of boys that arrive by car
= 20% of 60%
= 0.2 x 60 = 12%
Percentage of girls that arrive by car
= 60% of 40%
= 0.6 x 40
= 24%
Total Percentage of children arrive by car
= 12 + 24
= 36%
P(Arrive by car)
= 36%
= 0.36
Use the formula A = p( 1 + x)^n.
A = 1831.84(1 + 0.14)^6
You can finish.
