1 answer:
Answer:
x =
Step-by-step explanation:
The bar above the 3 indicates the 3 is a repeating digit , that is
0.3333....
We require 2 equations with the repeating digit placed after the decimal point
let x = 0.3333... (1)
Multiply both sides by 10 )
10x = 3.3333... (2)
Subtract (1) from (2) thus eliminating the repeating digits
9x = 3 ( divide both sides by 9 )
x = =

The image of the arrow is missing, so i have attached it.
Answer:
A_t = 69.5 cm²
Step-by-step explanation:
In a second image attached, I have divided the arrow into triangle and rectangle.
From the second image,
A1 is area of triangle while A2 is area of rectangle
Area of triangle is; A1 = ½bh
Our triangle base is given as 9 cm.
To get the height, we will subtract the rectangle height of 8 cm from the total arrow height.
Thus; height of triangle; h = 11 - 8 = 3cm
Thus;
A1 = ½ × 9 × 3
A1 = 13.5 cm²
Formula for area of rectangle is;
A2 = length × breadth
A2 = 8 × 7
A2 = 56 cm²
Thus, total area of arrow is;
A_t = A1 + A2 = 13.5 + 56
A_t = 69.5 cm²
