The discount was 48%. The original price was $28.00, but the new price was $14.60.
Answer:
Step-by-step explanation:
2x²+8=80
2x²=80-8=72
x²=72/2=36
x=±√36
x=±6
so x=6 is one solution other is x=-6
Answer:
B and C
Step-by-step explanation:
For the first one, any two shades of paint will be different if they're different numbers, and the same shade if they're the same numbers. Knowing this, we can see:
A , D, and E are all the same number (1/3) so they're all the same shade.
The remaining shades (B and C) are both 1/2 so they're the same shade.
Therefore there are two different shades of paint.
For the second one, we know that the more red the shade is, the larger the fraction will be. So we just need to look for the shades with the largest fraction. These are shades B and C, because they are both 1/2 (aka 50% red), whereas all the others are 1/3 (aka 33.3% red).
Answer:
1.01*10^-4
Step-by-step explanation:
first nonzero digit is 4 places to the right of the decimal point
.000<u>1</u>01
move decimal point 4 places to the right
1.01
multiply by 10^-4 since it was 4 places to the right
1.01*10^-4
Answer:
y-1=2(x-3)
Point slope form is Y-y1=m(X-x1)
M= slope
y1= the y co-ordinate of your point
x1= the x co-ordinate of your point
