He must work an additional 28 hours to earn another $217.00.
Answer:
2.2%
Step-by-step explanation:
Use the percent error formula:
% error = | (approx - exact) ÷ approx | x 100
Plug in the approx. and exact values:
| (8.9 - 8.7) ÷ 8.9 | x 100
| (0.2) ÷ 8.9 | x 100
= 2.2
So, the percent error is 2.2%
Answer:
x=11
Step-by-step explanation:
5x = 55
Divide each side by 5
5x/5 = 55/5
x = 11
.85*36,000=30,600
30,600*0.09=2754
30,600-2754=$27,846
Proof: square roots of prime numbers are irrational. the square root of any prime number must be an irrational number. For example, because of this proof we can quickly determine that √3, √5, √7, or √11 are irrational numbers.
moreover, √7= 2.645751311064590
This is an irrational. number
