<u>Statement</u> . . . . . <u>Reason</u>
1. c ║ d; ∠4 = ∠5 . . . . . Given
2. ∠4 = ∠7 . . . . . Alternate interior angles are equal
3. ∠5 = ∠8 . . . . . Vertical angles are equal
4. ∠7 = ∠8 . . . . . Substitution
5/9 divided by 3/4
5 ÷ 3
9 4
5 × 4 = 20
9 3 27
20/27 is your answer. Hope this helps.
Answer:
<u>About 8.5 mins</u>
Step-by-step explanation:
This is a compound decay problem, which goes by the formula:
Where
F is the future amount (we want it to be 380)
P is the present amount (980 now)
r is the rate of decay per minute (10.5% = 10.5/100 = 0.105)
t is the time it takes (what we want to find)
Substituting, we get our answer to be:
SO, it is going to take about 8.54 mins, rounded to nearest tenth (1 decimal), we have:
<u>About 8.5 mins</u>
45 km per hours because it is distance divided by time
