Answer:
Number of Significant Figures: 3
The Significant Figures are 9 0 5
Step-by-step explanation:
Answer:
Smaller Number = 10
Larger Number = 33
Step-by-step explanation:
Let the smaller number be "x" and the larger number be "y"
5 TIMES smaller is SUBTRACTED from TWICE larger, the result is 16, we can write:
2y - 5x = 16
and
Larger increased by 3 TIMES SMALLER, result is 63, so we can write:
y + 3x = 63
We can write this in terms of x, as:
y = 63 - 3x
Now we put this in equation 1 and solve for x first:
2y - 5x = 16

Now,
y = 63 - 3x
y = 63 - 3(10)
y = 63 - 30
y = 33
Smaller Number = 10
Larger Number = 33
Area of a square is a².
4² = 16
Now find the area of the semicircle.
(πr²)/2
(3.14)(2)²/2
12.56/2
6.28
Now add the areas to find the total area.
6.28 + 16 = 22.28
Hope this helps :)
