Answer:
Amount = £37
Step-by-step explanation:
Let Rose be represented by R.
Let Haydn be represented by H.
Given the following data;
Total amount = £250
Ratio of R:H = 2:3 = 2 + 3 = 5
To find how much Rose earned;
R = 2/5 * 250
R = 500/5
R = £100.
For Haydn;
H = 3/5 * 250
H = 750/5
H = £150
Next, we calculate the amount Haydn gave to charity;
Percent = 42% = 42/100 = 0.42
H = 0.42 * 150
H = £63
To find how much more Rose gave to charity than Haydn;
Amount = R - H
Amount = 100 - 63
Amount = £37
Answer:
The question's most likely incorrect
Step-by-step explanation:
Because if it were to be rearranged as 15 being the hypotenuse, and 9 and 12 being the two other sides, that would have been more valid.
Because according to Pythagoras, 15 squared = 12 squared + 9 squared
225 = 144 + 81.
And then it WOULD form a right angled triangle.
So...
Answer:
h = 9 feet.
Step-by-step explanation:
The height at the top of a roller coaster hill is 10 times the height h feet of the starting point. The height decreases 100 feet from the top to the bottom of the hill. The height at the bottom of the hill is -10 feet.
Therefore, there is a zero elevation point between the starting point at h height and the bottom of the hill which is at - 10 feet from the zero elevation point.
Now, the elevation of the top of the hill from the zero elevation point is (100 - 10) = 90 feet.
Therefore, 10h = 90
⇒ h = 9 feet. (Answer)
Answer:
