A = 16 over 49
b= 2 then 1 over 10
Answer:
ok give me brainliest ill give you brainliest :)
Step-by-step explanation:
Answer:
a = 2 [m/s²]
Step-by-step explanation:
Here we need to think back to our good old friend Newton and his second law:
F = m·a
The first thing we are given is that when m = 22 [kg], a = 3 [m/s²]. With this, we can calculate F:
F = 22 · 3 = 66 [N]
Now that we have the force acting upon the two objects, we can calculate the second object's acceleration using this force:
F = m·a
⇒ a = F / m (divide both sides by m)
⇒ a = 66 / 33 = 2 [m/s²]
Answer:4 and 9 are the numbers
Step-by-step explanation:
One way of approaching this would be to add up 3 and 2, obtaining 5, and then multiplying 15 by 3/5:
15(3/5) = 9
Then write and solve the equation of ratios:
3 9
-- = ------
2 x
Then 3x=18, and x=6. Thus, 15 divides into 9 and 6, which has the ratio 3:2.
