1/2 is the simplified version
Answer:
1.81530×10⁴
Step-by-step explanation:
Keep the first 6 digits of the mantissa:
1.81530×10⁴
__
Here, the 7th digit is less than 5, so it and all to the right are dropped.
Figure are significant if they are a number greater than 0, if they're after a decimal place, or if they're a 0 in between significant numbers
190 has 2 sig figs
1.8 has 2 sig figs
26 has 2 sig figs
206 has 3 sig figs
thus, the answer is 206
Answer:
75
120
Step-by-step explanation:
Let the first mechanic's hourly rate = x
Let the second mechanic's hourly rate = y
x + y = 195
15x + 5y = 1725 Divide this equation by 5
3x + y = 345 Write the first equation below this one. Subtract
<u>x + y = 195</u>
2x = 150 Divide by 2
x = 150/2
x = 75
====================
x + y = 195
75 + y = 195
y = 195 - 75
y = 120
