6.20÷4 = 1.55
price per individual dounut =$1.55
1.55×12=18.6
12 donuts =$18.6
Answer: 12 months (1 year)
We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12
You want to divide $339.12 with $29.26 to find the total months.
339.12 / 29.26 = 11.6
CHECK:
You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.
29.26 * 12 = 351.12
It will take Alision 12 months (1 year) to buy her stereo.
Question:
Convert the angle θ=260° to radians.
Express your answer exactly.
θ = ___ radians
Answer:
260° = 13π/9 or 4.54 rad
Step-by-step explanation:
Given
θ=260°
Required
Convert from degree to radians
To convert an angle in degrees to radians, we simply follow the steps below.
1° = 1 * π/180 rad
Replace the 1° with x
So,
x° = x * π/180 rad.
Now, we assume that x = 260
This means that we substitute 260 for x. This gives
260° = 260 * π/180
260° = 260π/180
Divide numerator and denominator by 20
260° = 13π/9
We can leave the answer in this form or solve further.
Take π as 22/7. This gives
260° = 13/9 * 22/7
260° = 286/63
260° = 4.5396825397
260° = 4.54 rad (Approximated)
