(1.3X10^6ft/hr)(2.8X10^3hr)
(1.3*2.8)(10^6*10^3)
Rule (a^b)(a^c)=a^(b+c)
(3.64)(10^(6+3))
3.64(10^9)
3.64X10^9 ft
Technically we only had two significant figures and the answer should be:
3.6X10^9 if we were to express our answer to the correct number of significant figures....
Answer:
Mabel would have to draw a new angle that measured 97°.
Step-by-step explanation:
Supplementary angles always add up to 180°.
So, she would have to draw an angle that was 
°
°
.
So Mabel would have to draw a new angle that measured 97°.
40 dollars they each spent 40 dollars from 70 dollars
Answer:
y = 41°
Step-by-step explanation:
∡ y and 139° are adjacent angles and sum to 180° , that is
∠ 1 + 139° = 180° ( subtract 139° from both sides )
∠ 1 = 41°
