Answer:
Step-by-step explanation:
2π = 360
2π/2 = 360/2
π = 180
π/6 = 180/6
π/6 = 30°
sin π/6 rad = sin 30° = 1/2 or 0,5

<span>When you figure out what y is, multiply it by 7, and then divide 7y ÷ 119. Use the decimal you get, multiply it by 100 and you have the percent.
</span>and also <span>The easiest way to do this type of problems is to use the formula: </span>
<span>is/of = %/100 and substitute into the equation the values associated with each part of the proportion. </span>
<span>119/7y = %/100 </span>
<span>Now cross multiply: </span>
<span>119 * 100 = 7y% </span>
X = 4 y = - 3
Substitute x for 4 and y for - 3
<u>x² - 4y
</u> 2
<u>4² - 4 *(- 3</u><u>)
</u> 2
<u>16 - ( - 12 )</u>
2
<u>16 + 12</u>
2
<u>28</u> = 14
2
Solution: 14
Since 6 lbs of apples cost $12, 1 lb will cost $2.
8 times 2 = 16
8 lbs of apples cost $16

Write their age ratio
E : F : G = 9 : 13 : 18
From the ratio above, we know that the sum of the ratio is
9 + 13 + 18 = 40
Count their money
For Eli, the ratio is 9
Eli's money = Eli's ratio/the sum of ratio × the sum of money
Eli's money = 9/40 × 800
Eli's money = 180
For Freda, the ratio is 13
Freda's money = Freda's ratio/the sum of ratio × the sum of money
Freda's money = 13/40 × 800
Freda's money = 260
For Geoff, the ratio is 18
Geoff's money = Geoff's ratio/the sum of ratio × the sum of money
Geoff's money = 18/40 × 800
Geoff's money = 360
So the answer:
Eli = £180
Freda = £260
Geoff = £360
