Given:
A sum of money is divided between A,B and C in the ratio 9:8:7.
Total sum is 480.
To find:
The part of money A get.
Solution:
Let A, B and C get 9x, 8x and 7x respectively.
Total sum is 480.
Divide both sides by 24.
Now,
Therefore, amount received by A is 180.
Answer:
Step-by-step explanation:
The trick is not to get all caught up in Pythagoras. There is a much simpler way to do it. Find the area of the triangle two different ways. DG and DE are at right angles. That is one way to find area. The other is use the height (DF) and multiply that by the hypotenuse GE.
DG*DE/2 = GE * DF/2 Multiply both sides by 2
DG*DE = GE * DF
DG = 8
DE = 15
GE = 17
8*15 = 17* DF
120 = 17 * DF Divide by 17
120/17 = DF
DF = 7.06
Answer:
2
Step-by-step explanation:
1. "Kevin has a 15% off coupon for buying water bottles at Walmart.
One water bottle is usually $2.00. How much did Kevin pay with his coupon?"
2. $1.70.
3. The answer is $1.70, because $2.00 * 0.15 = 30 cents, which is how much the coupon is worth. The sale price is the original amount minus the coupon's monetary value (which is $2.00 - $0.30 = $1.70).
4. I'll leave that part to you lol
The answer would be B. y = 4x - 2
