Answer: 20.833mph.
Step-by-step explanation:
Using the motion Formula,
speed = distance/time.
This means:
distance = speed * time.
To find the value of "s" in the question, we have to calculate the distance both trains travelled in terms of "s" and sum it to give us 300miles.
For train A,
Speed = S miles per hour
time taken to reach current position= 7hours.
Hence, the distance travelled by train A
Distance A = 7s.
For train B,
Speed= (S + 10)miles per hour.
time taken to reach current position= 5hours (since train B left two hours after the departure of train A)
Distance = speed * time
Distance B = (S + 10) * 5
Distance B = 5s + 50.
Hence, adding both distance to sum up to 300miles, it becomes:
300 = 7s + 5s + 50
300-50 = 12s
250 = 12s
s = 20.833mph.
Answer:
Step-by-step explanation:
b/c they are similar triangles and b/c you know one has an angle of 59 and the other has an angle of 75 that they both have those angels.. and that the total is 180
they are asking what is angle S .. that looks like it's the same one as angle P on the other triangle so ...
S= 59°
Answer:
yes it's similar triangle because it has same shape but size is not equal
Answer:
An exponent
Step-by-step explanation:
look at PEM/DA/S
Parenthesis
EXPONENTS
and then you can stop the first operation is 7^3
this is an exponent
(also brainliest if this helped please!)
About Reciprocal:
It's when a fraction is flipped.
Example:
- 2/3..... The reciprocal for 2/3 is 3/2.
- 3/5.... The reciprocal for 3/5 is 5/3.
