Answer:
A. Perpendicular
Step-by-step explanation:
When lines and/or points are in perpendicular to one another, the perpendicularity line between them measures the distance between both points and/or lines.
So to measure the distance between point c and line AB, a perpendicular line has to be drawn from c to AB or from AB to c. Either of these will arrive at the same result.
It should also be noted that the angle at the point of intersection of perpendicular lines is 90°.
For 4. (Apples to balloons) it is really simple. All you have to do is count the amount of balloons and apples and turn into a ratio, which is a basically a fraction. The answer for that would be 4:2
For the other 4, im not sure what the answer is as i cant really see it that well.
3 and 3 are pretty easy too. All you need to do is find a common factor. For the first number 3, 6 and 8 can both be divided by 2. The will turn it in 3/4, which is as simple as the number can get. The next one can also be divided by 2, which will turn it into 5/7. Once again, this is as simple as it can get.
Answers:
3. 3/4
3. 5/7
4. ? (couldn't see it)
4. 4:2
Answer:
The decrease is 21%
Step-by-step explanation:
So lets say the Original area is Pi X (Radius^2)
Lets call Radius as R
For the new radius, it would be: R + 0.1R which is 1.1R
The new area is: Pi X 1.1R^2, which going further is 1.21 after squaring 1.1.
The Original area is: Pi X Radius^2
To find the percent decrease, subtract the new area by the original, cross out Pi X Radius squared and you are only left with 21%
I am in middle school so I don't know if it is going to be incorrect, but I ask you to give it a try and tell me if it was right or not. I have barely done this topic but recently I had a bonus homework question on a question almost exactly like this and this is the way I did it and I was correct. Thanks! Hope it helped! :)
The expression would be 34 - 1.5d
34 ounces minus 1.5 ounces multiplied by d (the amount of days that have gone by.)
