It looks like you have to do distance formula. It's basically this:

D = \sqrt{(y_{2}-y{1})^{2} + (x_{2}-x{1})^{2}   } (ignore the A, i dont know how to get rid of it sorry)

I would then plug in the points of A(1,7) and B(10,3).

D = \sqrt{(7-3)^2 + (10-1)^2  }

Then I would get the square root of 4^2 + 9^2

= square root of 16 + 81

= square root of 97

So the length of AB would be the square root of 97

1)A new iPad costs $229 and is on sale for 7% off. How much is deducted from the original price? 2)A sweatshirt regularly sells
Novosadov [1.4K]
The first one is 212.97 You would do (229 x 7)/100=16.03 So because you got 16.03 you would do 229 - 16.03 = 212.97 The second one is 40.08 And you would do the samething here. But instead of 7 you would do 15 (48.00 x 15)/100 =7.2. So you would do 48.00 - 7.2 = 40.08 So the second one is 40.08 And The first one is 212.97

Here are the ingredients for making fish pie for 6 people.
yarga [219]
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.
