Answer:
Step-by-step explanation:
using the simple interst formula;
SI = Principal * Rtae * Time/100
Given
Principal = $550
SI = $80
Time = 3 month = 3/12 years
Required
Annual interest rate
Substitute
80 = 550 * R * 3/12*100
80 = 1650R/1200
96000 = 1650R
R = 1650/96000
R = 0.017
Rate = 0.017 * 100 = 1.7%
Ok so I will do only one and only put the answer for the others
ok so nearest xmm means that you havet o find teh smalles then largest so
1. legnth times width=area
so find max and min area
5 mm eror
legnth=645
width=400
so the legnth and witdth could be area
640 (subtract 5 for rerror) and 395 (subtract 5 for error
or
650 (add 5 for error) and 405 (add 5 for error)
so areas could be
640 times 395=252800
650 times 405=263250
upper bound=263250 mm^2
lower bound=252800 mm^2
so basically subtract the error to find minimum possible area and then add error to original measues to find max possible area
2. upper bound=29 m
lower bound=27 m
3. perimiter=2(L+W)
2((145-5)+(28-1))=lower bound=334 m
2((145+5)+(28+1))=upper bound=358 m
4. (35-1)(26-1)=lower bound=850 cm^2
(35+1)(26+1)=upper bound=972 cm^2
5. 2 sig figs (not sure about this question as much)
nonzeros are significant
30 is 1 sig fig since 0 is not significant
therfor
30.9 to 30.0
18=2 sig figs so that is alreight
upper bound of width=18
30.9 times 18=upper bound=556.2 cm^2
30.0 times 18=lower bound=540 cm^2
ANSWERS
1. upper bound=263250 mm^2
lower bound=252800 mm^2
2. upper bound=29 m
lower bound=27 m
3. lower bound=334 m
upper bound=358 m
4. lower bound=850 cm^2
upper bound=972 cm^2
5. upper and lower bound o 18=18
upper bound=556.2 cm^2
lower bound=540 cm^2
Answer:
Step-by-step explanation:
2x-6=3-x
+x on both sides
3x-6=3
+6 on both sides
3x=9
/3 on each side
x=3
4344 divided by 48= 91 meaning 91 rows can be filled
Answer:
16
Step-by-step explanation:
Use PEMDAS (Parenesis, Exponents, Mutiplication, Division, Addition, Subtraction)
Using PEMDAS we add 5+3 for it is in parenesis. We get 8 from that. Finally, we multiply 8 with 2 to get 16.
