Answer:
→Boys=6
→Girls=14
Step-by-step explanation:
Mean is the average
mode is most common number
we can do
hmm
average of 3 and 9 is 6
3,3,6,9,9 will work
we can make it vary slightly
2,4,6,9,9
mean is 6, mode is 9
Answer:
∠A=60
∠B=30
Step-by-step explanation:
∠A+∠B=90
So if then because 60+30=90
I hope that was enough explanation.
Have a nice day :) (please give me brainliest, I'm trying to reach the next rank, thank you)
Answer:
160 m²
384 m²
Step-by-step explanation:
The area of a trapezium is given by :
A = 1/2(a + b)h
h = height ; a and b = lengths
From the diagram :
A = 1/2(12 + 20)10
A = 1/2(32)10
A = 16 * 10
A = 160 m²
2.)
Area of parallelogram = base * height
Base = 24 ; h = 16
A = 24 * 16
A = 384 m²
38 + 2n = 124
2n = 124 - 38
2n = 124 - 24 - 14
2n = 86
Therefore:
n = 43
