Answer:
$33.60
Step-by-step explanation:
First we take 80% of $40.
1. $40 * 0.80 = $32
Next we take 105% of $32.
2. $32 * 1.05 = $33.60
Answer:
12
Step-by-step explanation:
Answer:
Yes, 4 18/12 is equal to 5 6/12.
Step-by-step explanation:
Given that
4 18/12 = 5 6/12
11/2 = 11/2
Yes both are equal.
The two angles are x and 9x/5
<h3 /><h3 />
Let the two angles we require be x and y.
<h3 /><h3>Ratio of both angles</h3>
We have that the ratio of both angles are x:y
Since both angles are in the ratio 5:9, we have that,
x:y = 5:9
⇒ x/y = 5/9
<h3 /><h3>Value of the other angle</h3>
So, we Make y subject of the formula
Multiplying both sides by y, we have
y × x/y = 5/9 × y
x = 5y/9
Multiplying both sides by 9, we have
9 × x = 5y/9 × 9
9x = 5y
Dividing both sides by 5, we have
9x/5 = 5y/5
y = 9x/5
So, the two angles are x and 9x/5

Today: x=19
y=67+19=86
9 years ago: x=19-9=10
y=86-9=77
The total age 9 years ago: x+y=10+77=87
