Answer:
a-b=10
Step-by-step explanation:
add all the numbers then round
13+ 14+ 22+ 52+ 63+ 77=241
Round to the nearest ten
a =240
first rounding each number to the nearest ten and then add
13+ 14+ 22+ 52+ 63+ 77
10+10+20+50+60+80 =230
b= 230
a-b = 240-230
= 10
Answer:
the second one is the better deal
Step-by-step explanation:
Step-by-step explanation:
(3X-20)+(3X+5)=111(( SINCE 111 IS TOTAL ANGLE
6X-15=111
6X=126
X=21
EFG=3×21-20
=63-20=43
Answer:
318
Step-by-step explanation:
318 is the required answer

So given Figure we need to find total surface area
=Area(ABCD)+Area(BCRQ)+Area(QRSP)+Area(ADSP)+Area(ABQP)+Area(DCRS)
=(AB×BC)+(BC×CR)+(QR×RS)+(AD×DS)+(AB×BQ)+(DC×CR)
From figure,
AB=DC=PQ=SR=9 cm
BQ=CR=AP=DS=11 cm
BC=AD=QR=SP=3 cm
On substituting these values We get
Surface Area=(9×3)+(3×11)+(9×3)+(11×3)+(9×11)+(9×11)
=27+33+27+33+99+99=318
I hope it helped you
120 is the answer im pretty sure
