Megan wanted 50 beads that were originally $9.95. She had a coupon for 25% off and paid a sales tax of 6%. What was the total she paid for the beads?
9.95(0.75)(1.06)=7.91
The .75 is the coupon and 1.06 is the sales tax.
If the sales tax is 6%, add the decimal version of 6% to 9.95.
6% ⇒ 0.06
9.95 + 0.06 = 10.01
Since Megan has a 25% off coupon, find 25% of the full price by multiplying 0.25 by 10.01.
25% ⇒ 0.25
10.01 × 0.25 = 2.50
Now subtract 2.50 from 10.01.
10.01 - 2.50 = 7.51
Answer:The total price of the beads is $7.51.
Hope this helped!

what is the perimeter, in feet (ft), of a right triangle which has an area of 12 ft^2 and one leg that has a length of 4 ft?
Answer:
P = (10 + 2√13) ft ≈ 17.21 ftStep-by-step explanation:
A = 12 ft² - area of triangle
a = 4 ft, b - legs of right triangle
c - hypotenuse (third side of triangle)
A = ¹/₂ ab
12 = ¹/₂•4•b
12 = 2b
b = 6 ft
from Pythagorean theorem:
a² + b² = c²
4² + 6² = c²
c² = 16 + 36
c = √52 = 2√13 ft
The perimeter: P = a + b + c
P = 4 + 6 + 2√13 = (10 + 2√13) ft ≈ 10 + 7.21 = 17.21 ft

What's 2 divided by 9/10? I would really like to know. :)
Answer:
[tex]\frac{20}{9}[/tex] or 2 [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
1. Set up the problem : 2 ÷ [tex]\frac{9}{10}[/tex]
2. Since 2 is a whole number we can give it a denominator of 1, transforming the problem to: [tex]\frac{2}{1}[/tex] ÷ [tex]\frac{9}{10}[/tex]
3. Change the division sign into a multiplication sign.
[tex]\frac{2}{1}[/tex] × [tex]\frac{9}{10}[/tex]
4. Find the reciprocal by swapping the numerator and denominator on the second fraction
[tex]\frac{2}{1}[/tex] × [tex]\frac{10}{9}[/tex]
5. Multiply fractions
[tex]\frac{2}{1}[/tex] × [tex]\frac{10}{9}[/tex] = [tex]\frac{20}{9}[/tex] or 2 [tex]\frac{2}{9}[/tex]
