Answer:
$99
Step-by-step explanation:
First, it was on sale for 10% off. 10% = 0.1 = 1/10. 1/10 of 100 is 10, so we subtract 10 (because 10% off) to get $90. Then, the sales tax, which we add, is 10%. 1/10 of 90 is 9, so we add 9 to 90 to get our total to be $99
True. The midsegment of a triangle is halfway up the triangle, and since the top half and the full triangle are similar triangles, its dimensions are proportional.
This means half the height will give half the base (midsegment). So the midsegment is always half the length of the side it's parallel to.
Answer: 7/12
Step-by-step explanation:
1/3 + 1/3 = 2/3
2/3 - 1/3 = 1/3 (Rearrange the denominator together)
= 1/3 + 1/4
(Multiple 1/3 by 4 for the numerator and the denominator)
(Multiply 1/4 by 3 for the numerator and the denominator as well)
= 4 + 3 / 12
=7/12
