Answer:
$312
Step-by-step explanation:
Now, what we need to know is the cost of a melon since we know the cost of a bread fruit to be 8 yen.
What the question is simply saying is that the cost of 9 breadfruits and 10 melon equals the cost of 3 breadfruits and 12 melons.
To get her income per day, we need to get the amount she buys each melon. Let this amount be x yen.
Mathematically: 9(8 yen) + 10(x yen) = 3(8 yen) + 12(x yen)
Opening the brackets: 72 + 10x = 24 + 12x
48 = 2x , x = 24 yen
Her total daily income is thus 9(8) + 10(24) = 72 + 240 = $312
37.5/100=0.375 and 81/0.375=216
so the answer is 216
Answer:
It's 398
Step-by-step explanation.
Diameter of 8.
height of 12.
8 - .75 - .75= 6.5
6.5/2 = 3.25
3.25 x 3.25 x 12 x 3.14 = 397.995
round to the nearest whole number and you get
398
Take the diameter (8) an subtract is by both sides of the walls (0.75 each wall) that gives you 6.5. Take that 6.5 and half that, because you need to have the radius to solve volume problems, giving you 3.25. Then multiply 3.25 by 3.25 together ( I know it seems redundant but it just works easier this way) This gives you 10.5625. After that take 10.5625 then multiply it into 12, being the height, which gives you 126.75. Finally take 126.75 and multiply that into 3.14 (pie) giving you the answer.
Okay so 10. 7/10% =107/10% so in a decimal it would be .107
