X • 2 + 30 = 3800
1885 • 2 + 30 = 3800
3770 + 30 = 3800
3800 = 3800
Answer:
it will take 8 minutes
Step-by-step explanation:
Here, we want to
calculate the amount of time taken to fill the tank given the total amount of water in the tank.
Mathematically, the formula go
use is ;
w= 100 + 55t
540 = 100 + 55t
55t = 540-100
55t = 440
t = 440/55
t = 8
Answer:
d. 90°, 90°
Step-by-step explanation:
Both angles intercept 180° arc WZ. They are half the measure of the intercepted arc, hence both are 90°.
Use tI 84 calculator .
go to y= and then plug the equation in the side then you will find the answer
Step-by-step explanation:
change the unit
50 km per 1 hour
50 km/h = 50,000 m/ 3600 s = 13.8 m/s
the lorry speed is 13.5 m/s or 0.3 m slower than the limit
