Answer:
Divide by 1000.
Step-by-step explanation:
For example, 1 joule is 0.001 kilo joule.
1 divided by 1000 is 0.001.
If there were 30 joules, there would be 0.032 kilo joules.
Alright, so the book is on sale for 4 dollars right? So do 32/4 and that will be 8, so the percent is 8%
52) 115-3=112 that were given away
Now divide 112 by each, seeing if they give you a non mixed number.
The only one that would give you a full number would be 28. So there are 28 kids in his class.
54) 19-4=15
Now double 15 since he sold half, so he started with 30 stamps originally.
56) 500-2*=324
-2*=-176
age=88

Pythagorean Theorem is a² + b² = c²
Answer:
x = 55
Step-by-step explanation:
In a rhombus, each diagonal bisects a pair of opposite angles.
For this parallelogram t be a rhombus, the angles with measures 2x - 40 and x + 15 must be congruent.
2x - 40 = x + 15
Subtract x from both sides.
x - 40 = 15
Add 40 to both sides.
x = 55
