Answer:
Step-by-step explanation:
Let
Original price = p
Less Discount = 20%
Total discount paid for the item = 20% of p
= 20/100 * p
= 0.2 * p
= 0.2p
Actual price after discount = 100% - 20%
= 80%
Total price paid for the item = 80% of p
= 80/100 * p
= 0.8 * p
= 0.8p
I think is D I am so sorry if I’m wrong
Clare would need 80 of fish, (1/3 of 240 is 80.)
Ian would need 200g of butter (If you find the amount of each ingredient needed for a one person-pie, and multiply them by the amount of people you need to feed, you will get your answer.)
We know that 80g of butter is used for 6 people, so by dividing 80 by 6, we know that for a one person-pie, you would need 13.33g of butter. Multiply 13.33 by 15 to find out how many grams of butter he would need for a pie for 15 people.
Use double angle identity:

After substituting and moving to Right side of equation:

This is a quadratic, which can be solved by factoring or quadratic formula.
It may be helpful to replace sin(x) with another variable, then solve.

Now substitute sin(x) back in, we have

Using a unit circle or inverse sine function in calculator we can find the appropriate angles.
Answer:
To show that M is really the midpoint of the line segment PQ, we need to show that the distance between M and Q is the same as the distance between M and P and that this distance is half the distance from P to Q
Step-by-step explanation:
The midpoint M is then defined by M = ((x + X)/2,(y + Y)/2)
