Answer:
Obi's age is 18 and Oba's age is 9
Step-by-step explanation:
Let Obi's age be x and Oba's age be y
<u><em>Condition 1:</em></u>
x = 2y -----------(1)
<u><em>Condition 2:</em></u>
(x-4) = 3(y-4)
=> x -4 = 3y-12
=> x - 3y = -9 -----(2)
<u><em>Putting eq (1) in (2)</em></u>
2y - 3y = -9
=> -y = -9
=> y = 9
Now,
x = 2y
=> x = 2(9)
=> x= 18

Answer:
∠A=123°.
Step-by-step explanation:
From the given figure it is clear the CD and CE are two tangent lines on circle with center A.
Radius is perpendicular to the tangent at the point of tangency.
Smaller arc DE = (5x-2)°
It means central angle DAE is (5x-2)°.
Now, ADCE is a quadrilateral and sum of all angles of a quadrilateral is 360 degrees.
The value of x is 25.
Therefore, the measure of ∠A is 123°.
Answer:
189 seconds
Step-by-step explanation:
16% shorter,
Left side first and second group is 2.5% and 13.5% = 16%
189 is the max of that group
1.
18.98 per 1000
320,000 / 1000 = 320
18.98 x 320 = $6073.60
2. smoker: 9.36 * 100 = 936
non smoker: 7.85 * 100 = 785
936 - 785 = $151
