1) Take the perimeter and divide it by 4.
2) Take the answer from step 1 and square it (multiply by itself)
Subtract to find the amount of tax paid:
1890 - 1800 = 90
Divide the amount of tax by the price of the computer:
90 / 1800 = 0.05
Multiply the decimal by 100:
0.05 x 100 = 5%
The tax rate is 5%
Answer:
32
Step-by-step explanation:
x^2 + 4y = 16 + 20 = 32
Just do substitution.
Hope this helps.
Good Luck
First you multiply the two equations, equaling 3000000 kg and 60000 kg respectively. Once you have those numbers, you divide the Oakland mass by the Mapleville mass, so 3000000/60000. The answer is 50, to the tree is B, 50 times as big.
950 is a real number, and it is a rational number since it can be expressed as 950/1. Therefore, it falls into all of the categories expect irrational numbers.
