Answer: 46
Step-by-step explanation:
percentage scored = 92
number of correct question = x
total number of questions = 50
The formula for calculating the percentage scored
= number of correct question / total number of questions x 100
That is
92 = 
x 
cross multiplying :
x 
dividing through by 100 , we have
Therefore, she got 46 questions right
Answers:
- Distance = 20 meters
- Displacement = 4 meters North
=================================================
Explanation:
To find the distance traveled, we add the two values to get 8+12 = 20 meters.
------------
For the displacement, I recommend drawing a vertical number line. Mark the values 0, -8 and 4 on the number line. Going from 0 to -8 represents going 8 meters south. From -8, move up 12 units and you should arrive at 4 on the number line, which represents being 4 meters north of the original position 0. The displacement only cares about the start and end points, more specifically, the change between the two. The direction is also important for the displacement.
In other words, Michael started at 0, did a bunch of movements, and ended up at 4 on the number line. So we can simplify all those movements to one single movement of "move north 4 meters" to represent the displacement.
As you can see, it's possible to get a displacement of 0 meters, which is not the case for the distance traveled in the previous section.
Expand:
-3x - 9 = -3x - 3 - 5
Simplify:
-3x - 9 = -3x - 8
Add 3x to both sides:
-9 = -8
THERE IS NO VALUE FOR X THAT MAKES THIS EQUATION TRUE
$148 is how much you want. You already have $40.
$148 - $40 = $108. You need to make $108 more.
You get $12 per yard.
$108 ÷ $12 = 9. So, you will need to do 9 more yards to get your goal of $148.
Final Answer: 9 yards.
Answer:
The answer will be 54
Step-by-step explanation:
D = r x t
R equals to 6 and t equals to 9
So, substitute r with 6 and t with 9 which will give you distance = 6 x 9 = 54
