1. We assume, that the number 45 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 45 is 100%, so we can write it down as 45=100%.
4. We know, that x is 80% of the output value, so we can write it down as x=80%.
5. Now we have two simple equations:
1) 45=100%
2) x=80%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
45/x=100%/80%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 80% of 45
45/x=100/80
(45/x)*x=(100/80)*x - we multiply both sides of the equation by x
45=1.25*x - we divide both sides of the equation by (1.25) to get x
45/1.25=x
36=x
x=36
now we have:
80% of 45=36

Answer:
v = 1.62 m/s
Step-by-step explanation:
Given that,
Distance covered by the mouse is 5.56 m is in 3.42 seconds.
We need to find the velocity of the mouse. It is equal to the total distance covered divided by time taken. So,
So, the velocity is 1.62 m/s.
Answer:12 guest
Step-by-step explanation:
It cost $25, plus an additional $1 per guest. She wants to spend $37 on everything.
Let work this out:
37-25=12
She can invite 12 guest and meet her budget of $37.
The vertex is where the bottom(or top of the U) If you look at the picture the Vertex is (3, 1)
The vertex it a maximum because the parabola points down( the maximum it y=1)
Hope this helps :)
