Answer:
5/8
Step-by-step explanation:
The volume after 30 minutes is:
(4.5 gal/min) (30 min) + 115 gal = 250 gal
The fraction of total capacity is:
250 gal / 400 gal = 5/8
<span>y=-40x+100 This equation says your friend lives 100 miles away and travels 40 miles per hour. He takes 2.5 hours to get there.
y = -40x + 100 If y=0 then x = 100/40 = 2.5 hours and if x=0 then y=100.
You are 150 miles away and it takes you 2.5 hours to get there so your equation is:
0 = -2.5v + 150 You are solving for velocity.
v = 150/2.5 = 60 miles per hour. Now we can write the answer to the problem.
y = -60x + 150 Compare that to the original statement.
y = -40x + 100 Your buddy's speed is 40 and yours is 60. He has 100 miles to go and you have 150. Otherwise it's the same equation.</span><span>

Answer: thanks for the points 1=1==1=1=14+6-3=2
Step-by-step explanation:
The answer:
we observe that <span>m∠DBC = 130°
</span><span>
we should find the value of </span>mEDB to answer this question
Angle ABC is a straight angle, so m ABC= 180°, but
mABD + <span>m∠DBC = 180° (look at the figure)
</span>
so mABD= 180° - m∠DBC = 180 - 130 = 50°
therefore, mABD= 50°,
and BE bisects ∠ABD imiplies mEBA = mEDB, and mABD= mEBA + mEDB= 50°, it does mean 2x mEBA = 50°
and from where mEBA = 50°/2=25°
y/3 = h
Multiply both sides by 3:
y = 3h
