Answer:
1.) 3/5
2.) 3/10
3.) 50
Step-by-step explanation:
i believe my answers are right, they might be wrong. I'm not that old so I can't solve most of these problems.
1.) to get this, you need to multiply the remaining shirts and 2/3
2.) subtract 1/10, and 3/5 from 1, which equals 3/10
3.) is 3/10 is equal to 15, then 1/10 is equal to 5, 5*10=50
Step-by-step explanation:
1/5^(3+6)= 1/5^9

Answer:
v= 6km/h - 1km/h^2 * t
Step-by-step explanation:
From the information, it seems the runner is slowing down because the speed at 1st hour is 5km/h but at 3rd hour becomes 3km/h.
If v= velocity, v0= initial speed, t= time, and the a=acceleration then the function would be:
v= v0 + a * t
To find the acceleration you need to do this equation:
acceleration= velocity1- velocity3 / t3-t1
a = (3km/h-5km/h)/ (3 hour- 1 hour)
a = (-2km/h)/2hour= -1 km/hour^2
After that, you need to find the initial speed. Try to put the 1st-hour variable into the full equation. It would look like this
v= v0 + a * t
5km/h= v0 + (-1 km/hour^2 * 1 hour)
v0= 5km/h + 1km/h
v0= 6km/h
Then the full function would be:
v= 6km/h - 1km/h^2 * t
The graph would look like a backslash(\) from 5 gradually go down to 1.

Answer:
y = (-3/2)x + 1/2
Step-by-step explanation:
Note that slope intercept form = y = mx + b
Change the given equation so it matches the form:
3x + 2y = 1
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. First, subtract 3x from both sides:
3x (-3x) + 2y = 1 (-3x)
2y = -3x + 1
Next, Divide 2 from both sides:
(2y)/2 = (-3x + 1)/2
y = (-3/2)x + 1/2
y = (-3/2)x + 1/2 is your answer.
