The area of the arrow given in the figure is 610 square cm
<h3>Area of composite figure</h3>
The given figure is made up of rectangle and triangle. The area is expressed as:
Area = Area of rectangle + area of triangle
Substitute the given parameters
Area of the arrow = (15*20) + 0.5(31 * 20)
Area of the arrow = 300 + 310
Area of the arrow = 610 square cm
Hence the area of the arrow given in the figure is 610 square cm

Answer:
138.80
Step-by-step explanation:
I took 149.99 times 15% then times that by the tax rate to get your final answer.
Answer:
x = 4
Step-by-step explanation:
1.3x - 10 = 0.8x - 8
Add 10 to both sides.
1.3x = 0.8x + 2
Subtract 0.8x from both sides.
0.5x = 2
Divide by 0.5.
x = 4.
Proof:
1.3x - 10 = 0.8x - 8
1.3(4) - 10 = 0.8(4) - 8
5.2 - 10 = 3.2 - 8
-4.8 = -4.8
- The number of girls is 24.
- The number of boys that study French is 24.
- The numbber of boys that study German is 12.
- The number of girls that study French is 16
- The number of girls that study German is 8.
<h3>How to fill the frequency tree?</h3>
The number of girls = total number of students - total number of boys
60 - 36 = 24
The number of boys that study French = 2/3 x 36 = 24
The numbber of boys that study German = 36 - 24 = 12
The number of girls that study French = 40 - 24 = 16
The number of girls that study German = 24 - 16 = 8

Answer:
E) 6
Step-by-step explanation:
a/b = 6
36/b = 6
6b = 36
b = 36/6 = 6
b/x = 36
6/x = 36
36x = 6
x = 6/36 = 1/6
hence 1/x = 6
