Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine
Answer:
2) 1.77 in squared
3) 508.68 in squared
4) 50.24 ft squared
5) 562.6
6) 170.3
Step-by-step explanation:
2) A=r^2pi
d= 2r
3in= 2r
r= 3/2
(3/2)^2pi
7.06858/4
1.77 in^2
3) (18)^2pi
324(pi)
1017.876/2
508
4) (8)^2pi
64pi
201.062/4
50
5) A= 1/2(b1+b2)h
25 -4.2= 20.8
1/2(18+26)20.8
1/2(44)(20.8)
22(20.8)
457.6cm^2
A=lw
25(4.2)
105cm^2
105+457.6= 562.6
6) 2 triangles(1/2(6.2(5)))
31 m^2
18.3(11)
201.3m^2
201.3 -31= 170.3m^2
50.27 rounded to the nearest hundredth is 50.30
