6.7 x 10 ^-6 for 0.0000067
Answer:
She would pay $2.80 in sales tax.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
Megan paid $2.52 in sales tax on an item that cost $36.00 before tax. How much in taxes for $40.00 before taxes?
$2.52 - $36.00
x - $40.00
Applying cross multiplication
![36x = 40*2.52](https://tex.z-dn.net/?f=36x%20%3D%2040%2A2.52)
![x = \frac{40*2.52}{36}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B40%2A2.52%7D%7B36%7D)
![x = 2.8](https://tex.z-dn.net/?f=x%20%3D%202.8)
She would pay $2.80 in sales tax.
Answer:
6 pounds
Step-by-step explanation:
2 1/2 + 3 /1/3 + 1/6 = 6
Hey there! :)
In order to the find the missing side length of this triangle, we'll need to use the Pythagorean Theorem!
That equation is : a² + b² = c²
a = adjacent side
b = long side of rectangle
c = hypotenuse
We're already given the values of both a & c, so let's plug everything in!
a² + b² = c² → a = 10 , b = ? , c = 20
(10²) + b² = (20²)
Simplify.
100 + b² = 400
Subtract 100 from both sides.
b² = 400 - 100
Simplify.
b² = 300
Get the square root of b² & 300.
![\sqrt{b^2} = \sqrt{300}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bb%5E2%7D%20%3D%20%20%5Csqrt%7B300%7D%20)
Simplify!
b = 17.3
So, the missing side length is the first answer choice : 17.3~Hope I helped!~
