Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
Catherine walks her dog 5.25 miles because there are 7 days in one week and 3/4 x 7 = 5.25
Answer:
(b) 0.30 atm
Step-by-step explanation:
Given data
Initial pressure= 1.2atm
Initial volume= 1.0L
Final volume= 4.0L
Final pressure= ???
Let us apply the gas formula to find the Final pressure
P1V1= P2V2
Substitute
1.2*1= x*4
Divide both sides by 4
1.2/4= x
x= 0.3atm
Hence the final pressure is 0.3 atm
The value B is 7. If we apply B=7 the answer is 17 for the expression 17×
Step-by-step explanation:
The given expression is 17×
Step:1
Form an equation from given data,
17×
= 17..............................(1)
(∵ product equal to 17)
Step:2
Check for alternatives by apply the value of B in eqn (1)
Assume be value of B for check the equation
B=1
Equation becomes,
17×
= 2.4286 ≠ 17
Take, B=2,
17×
= 4.8571 ≠ 17
Take, B=3,
17×
= 7.2857 ≠ 17
similarly,
B=7,
17×
= 17 (∵ The product equals to 17)
Result:
So, the answer for B is 7.
This is easy trust me everything will be fine first drag it to the bottom right the same way you do it on the Hub and then go 4 units below and you’re all set.
