Answer:
8.2.69 ≤ x ≤ 17.31
11. x-7.31 ≤ 10
12. x≤17.31
Let the amount in the other Piggybank be x.
If positive;
x-7.31 ≤ 10
x ≤ 10+7.31
x ≤ 17.31
If negative
-(x-7.31) ≤ 10
-x+7.31 ≤ 10
-x ≤ 10-7.31
-x ≤ 2.69
Multiply both sides by -1
x ≥ -2.69
The compound inequality representing the amount of money in the other bank is -2.69≤x≤17.31
Step-by-step explanation:
Answer:
perimeter = 12 miles
area = 6 square miles
Step-by-step explanation:
Since it makes a right triangle, use the Pythagorean Formula.
3^2+4^2=c^2
9+16=c^2
25=c^2
5=c, so the hypotenuse of the right triangle is 5.
Perimeter = 3+4+5 = 12 miles
area = 1/2bh (1/2 base times height)
=1/2x3x4
=6
Area = 6 square miles
For the volume you have to cube (hence the name) the edge length:
(2.7)³ = 19.683 cm³
