They currently give me 15 euros a week, but I have convinced my parents to raise it for me by 12%. What will be my weekly money from now on.

Answers

Answer:

16.80 euros.

Step-by-step explanation:

12% = 0.12

So it will now be 15 + 15 * 0.12

= 16.80.

Answer:  16.80 euros

===========================================================

Explanation:

There are two approaches

The slightly slower approach is to do this

12% of 15 = 0.12*15 = 1.80

So you get an 1.80 euro raise and the new amount you get is 15+1.8 = 16.80 euros

The shortcut is to do this

1.12*15 = 16.80

This works because increasing by 12% is the same as taking 112% of that original amount.

Step-by-step explanation:

d = √[(-7+1)²+(-1-5)²]

= √[(-6)²+(-6)²]

=√(36+36)

=√72

= 8.5

Answer:

8.5

Step-by-step explanation:

we can plug those coordinates into the distance formula

d =  √(x2 - x1)2 + (y2 - y1)2

d= √((-7)-(-1)^2+((-1)-(5)^2

d = √36+36

d=√72 = 8.48 or 8.5
