First, let's get rid of the unneeded info.
Oldest brother has $108 (3/5 the total)
Youngest brother has $x (1/10 the total)
Next let's find out the total. We do this by multiplying the oldest brothers money by 5/3 (the reciprocal).
108 × (5/3) = 180.
So the total amount of money is $180.
Finally, do 180 × (1/10) to find the youngest brother's amount.
180 × (1/10) = 18.
The youngest brother has $18.
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
Answer:
c) rad 3/2
Step-by-step explanation:
If Cos 30° equals rad 3/2 then the sin 60° equals rad 3/2.
Let s represent the number of sales, and t the total pay
the equation to represent this situation is t = 2s + 50
so set t to 100, and solve for s
100 = 2s + 50
50 = 2s
25 = s
you need to make at least 25 sales
