Answer:
At a distance of 525 km from the station both trains meet.
Step-by-step explanation:
Speed of the first train = 75
Speed of the second train = 105
Distance traveled by first train in two hours = 75 × 2 = 150 km
When the first train traveled a distance of 150 km than second train starts from the station.
Let suppose the two trains meet after T hours.
Value of T is given by
Put the value of D & & we get
T = 5 hours
Thus the two trains meet after 5 hours &
⇒ Distance from the station is = Speed of second train × 5
⇒ Distance from the station is = 105 × 5
⇒ Distance from the station is = 525 km
Therefore at a distance of 525 km from the station both trains meet.
Answer:
A
Step-by-step explanation:
please give me brainliest
Well, one line is equal to 180
Starting with the bottom half, there is a right angle so 180-90 is 90
then take the degree that is given to you(47) and subtract it 90-47 is 43
so angle 4 is 43 <span>°
given that,andgle 3 is 90</span><span>° because its equal to the right triangle on the bottom
</span>2 is equal to 4(43<span>° )
</span>which leaves 1 to be 47<span>°

Hope this helps
Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:
Each meter costs $2. So, the total cost will be:
Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:
Subtract:
So, 65.21 meters of ribbon will be left.
