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
Answer:
need pictures of the graphs
Step-by-step explanation:
basically, you'll be looking for a graph that has shifted to the RIGHT 4 units and down 2 units
Complementary angles are adjacent angles which add to equal 90 degrees (a right angle). To find m∠A in these figures, set the sum of the known angle measure and the unknown angle measure, A, equal to 90 and solve.
10)
90 = 67 + A
23 = A
m∠A = 23°
11)
90 = 57 + A
33 = A
m∠A = 33°
12)
90 = 44 + A
46 = A
m∠A = 46°
Tan330:
Apply the reference angle ( 360-330 = 30)
Now you have tan(30).
Make it negative because tangent is negative in the 4th quadrant:
-tan(30)
The value of -tan30 is -√3 /3
