The answer would be : A parallelogram with congruent sides does NOT guarantee that a quadrilateral is a rectangle
Answer:
The Large Box Weighs 18 kg, and the small box weighs 6.5 kg
Step-by-step explanation:
Let a= the weight in kg of a large box
Let b= the weight in kg of a small box
Multiply both sides of (1) by 4 and subtract (2) from (1)
1. 20a+8b=412
2. -3a-8b= -106
17a=306
a=18
and
5*8+2b=103
90+2b=103
2b=13
b=6.5
Answer:
2/3
Step-by-step explanation:
Answer: I believe the answer is around/about 56.55
Step-by-step explanation: C=2πr=2·π·9≈ 56.54 or aound 56.52
Formula: C=2πr
Simplified Equation:
2 x 3.14 x 9= 56.52 - 56.55
Good luck!! I hope this helps! All you have to do is memorize the formula, break down & simplify the numbers and equation and you're golden!!
Edit: I reccomend checking out Khan Academy for math help!
