So,
1400 people in total. Though, subtract 200 for the amount of extra adults. This makes 1200. Divide that by two. You get 600
You need to add 200 to the 600 to get the amount of adults. The amount of adults on board is 800.
The amount of children on board is 600.
600 plus 800 equals 1400, it makes sense. :P
Answer:
Area = pi r squared
Step-by-step explanation:
If you need to, sometimes your teacher will ask you to leave you answers in terms of pi, or keep pi as 3.
The slope is -3/2
Use the two ordered pairs (-2,0) and (0,-3) and do y2-y1/x2-x1
-3-0/0+2= -3/2
Answer:
6. x + x + 14 = 90
2x + 14 = 90
2x = 76
x = 38
angle b = 38 + 14 = 52°
7. angles on a straight line add up to 180°
x + x - 32 = 180
2x = 212
x = 106°
angle d = 106 - 32 = 74°
8. vertically opposite angles are equal
7x - 80 = 3x
-80 = -4x
20 = x
angle 1 = 7(20) - 80 = 60°
angle 2 = 3(20) = 60°
Answer:
13
Step-by-step explanation:
This triangle appears to be 5 units wide and 12 units tall.
Using the pythagorean theorem, a^2 + b^2 = c^2, we get 25 + 144 = 169 or 13^2.
Therefore the answer is 13.
