Answer:
72 kph
Step-by-step explanation:
The first sentence tells you the speeds are proportional. So, you can write the proportion ...
kph/mph = 120/75 = x/45
Multiplying by 45 gives x:
x = (45)(120/75) = 72
72 kph is 45 mph.
5. 9 - t/6 = 5
6. 12 + 8k = 48
7. 9 • 5t < 6
8. 4 • w <_ (less than or equal to) 51
Answer:
25% of 140 is 35
Step-by-step explanation:
If 35 is 25% then we can multiply it by 4 to get 100%.
35 x 4=140
This is actually a science question, this is because the air particles with the warmer temperature always go up and air particles with the cooler temperature always goes down, and this process is called convection.
I hope this could help you ;)
So y=mx+b
b is the y-intercept or where they cross the y-axis so just set a y-intercept and change the slope
so if y-intercept is 7
y=3x+7
y=2x+7
y=8x+7
y=-1/4x+7
and so on
