Answer:
b^20/a^12
Step-by-step explanation:
b to the power of 20 over a to the power of 12
Let x and y be the rate per hour for Mechanic 1 and 2 respectively.
Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)
Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
-5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115
Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour
Answer:
pretty sure its D but idk
Step-by-step explanation:
First guess: 1200
Second guess: 106
So this triangle is considered a "special triangle". The 30-60-90 triangle rule states that if the short leg is n, then the hypotenuse is 2n and the long leg is n√3.
In this case, since the short leg is 7, x = 14 and y = 7√3. The correct answer that has this is B.
