Answer:
The expression is: ![\text{total thickness} = \text{cookie thickness} + \text{frosting thickness}](https://tex.z-dn.net/?f=%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Ctext%7Bcookie%20thickness%7D%20%2B%20%5Ctext%7Bfrosting%20thickness%7D)
The thickness of the cookie is:
cm
Step-by-step explanation:
The cookie is formed by two layers, the cookie and the frosting. So if we want to know the total thickness of the cookie and frosting we need to sum the thickness of each layer as shown below:
![\text{total thickness} = \text{cookie thickness} + \text{frosting thickness}\\\text{total thickness} = \frac{9}{10} + \frac{33}{100}\\\\\text{total thickness} = \frac{10*9 + 33}{100}\\\\\text{total thickness} = \frac{123}{100} \text{ cm}](https://tex.z-dn.net/?f=%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Ctext%7Bcookie%20thickness%7D%20%2B%20%5Ctext%7Bfrosting%20thickness%7D%5C%5C%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Cfrac%7B9%7D%7B10%7D%20%2B%20%5Cfrac%7B33%7D%7B100%7D%5C%5C%5C%5C%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Cfrac%7B10%2A9%20%2B%2033%7D%7B100%7D%5C%5C%5C%5C%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Cfrac%7B123%7D%7B100%7D%20%5Ctext%7B%20cm%7D)
The expression is: ![\text{total thickness} = \text{cookie thickness} + \text{frosting thickness}](https://tex.z-dn.net/?f=%5Ctext%7Btotal%20thickness%7D%20%3D%20%5Ctext%7Bcookie%20thickness%7D%20%2B%20%5Ctext%7Bfrosting%20thickness%7D)
The thickness of the cookie is:

When you have a right triangle (A triangle which has a angle of 90°), you can find the "Sine". This is one of the basi trigonometric ratios. By definition, the Sine is:
Sin(α)=Opposite leg/Hypotenuse
You want to find Sin(A), so the opposite leg will be 8√3 and the hypotenuse will be 16.
When you substitue these values, you have:
Sin(α)=Opposite leg/Hypotenuse
Sin(A)=8√3/16
When you simplify, you obtain:
Sin(A)=4√3/8
Sin(A)=2√3/4
Sin(A)=√3/2
Which is the ratio for Sin(A)?
The answer is: The ratio for Sin(A) is √3/2
Answer:
0.47/94=200?
Step-by-step explanation:
Step-by-step explanation:
<h2>a - b = a + (-b)</h2><h2>a + b = a - (-b)</h2>
for any real numbers
A+B = 2X -2
A-B = 4X -8
Add the equations,
2A = 6X - 10
A = 3X - 5
Now, 3X - 5 + B = 2X - 2
B = 2X-3X - 2 + 5
B = 3 - X
Hope this helps!
