Osamuyipeace:
its 340 not 440

yeah thanks.

Ada96:
plz how

total cost for 4 bag s of rice ---4x( t 56)


total cost for 3 bags of beans---3x(t 26)


convert 56 & 26 base 7 to base 10.


56 base 7 = 41 base 10


26 base 7= 20 base 10


hence the total cost of 3 bags beans = 3(20)= 60


total cost of 4 bags of rice = 4(41)= 164


total cost of food= 164 + 60= 224 base 10


thequestion says in MINO (M) base 8


therefore convert 224 base ten to MINO base 8

= 8 / 224

8/ 28 R 0

8/ 3 R 4


0 R 3



SO ITS 340 MINO

u no maths ohh

i just dey learn from my boss (robin clitonpa...)
good evening ma.

RobinHez:
maths questions
solve for p in the following equation given in base two: 11(p+110) = 1001p.
a. 10
b. 11
c. 110
d. 111

open bracket. 11P+ 110(11) = 1001P 11p + 10001= 1001p 10001= 1001p - 11p 10001= p(1001- 11) P= 10001/ (1001-11) P = 10001/110
recall 110(11)= 10001
P= 110(11)/110
P= 11

physics @ McHenry99. Range P/Range Q= SIN 2 @/ SIN 2@ =SIN2 (30) / SIN 2 (60) = SIN 60/ SIN 120. = SIN 60/SIN 60 (SINCE SIN 120= SIN60) = 1

@ clitonopa
T= W - Ma a= v/t v= o a= o (not all cases though)
so T= W- m(0) T= W
so its same as the weight of the man.
