%= (exact-appropriate)/exact
so 279.45-250.55 divided by 279.45
basically .103417 nearest tenth is 10.3%

Answer:
800,000
Step-by-step explanation:
The 9 makes the 7 round up making it 800,000.
Answer:
22 degrees
Step-by-step explanation:
158 x 2 is 316
360 - 316 = 44
44 / 2 = 22
and both are the same angles for each set of angles.
4mm
The sides of the new garden can be represented by x+9. x is the original size and 9 is the added 9mm. Multiply the sides to get (x+9)(x+9) or

this will equal the area. Create an equation to solve for the unknown original length.

Take the square root of both sides
13=x+9
Subtract both sides by 9
4=x The original side was 4mm long
Step-by-step explanation:
a=4 so 3a becomes 3x4.
3x4=12
12+6c^2
C=2 so 6c^2 becomes (6x2)^2
6x2=12 and 12x12 because of the exponent.
12x12=144
12+144=156
If it's wrong, i'm sorry
