Answer:
The length of the ramp must be at least 14.71 feet
Step-by-step explanation:
Given
<em>See attachment for complete figure</em>
Required
Length of the ramp (z)
To do this, we consider sin of angle A ().
So, we have:
This gives:
Make z the subject
<em>The length of the ramp must be at least 14.71 feet</em>
Answer: x = 2
Step-by-step explanation:
1. Distribute 4 to x - 3: 4x - 12 + 5 = 1
2. Combine -12 and 5: 4x - 7 = 1
3. Add 7 on both sides: 4x = 8
4. Divide by 4 on both sides: x = 2
I hope this helps :)
so basically this is obviously easy and number 1 is australia and asustralia is the answer too 2
Answer: b)
Step-by-step explanation:
Given,
speed of train A travelling east = 55 mph
speed of train B travelling west = 70 mph
time train A travelled while train B was at rest = 45 min or
so, Distance travelled by train A while train B was at rest =
=
Now, after 'T' hour both the train will travel;
train A = 55T
train B = 70T
hence, the distance (D) between two train in miles will be;
⇒ D = 41.25 + 55T + 70T
⇒ D = 125T + 41.25
