Answer:
92°
Step-by-step explanation:
The exterior angle is equal to the sum of the 2 opposite interior angles, that is
2x - 2 = x + 45 ( subtract x from both sides )
x - 2 = 45 ( add 2 to both sides )
x = 47
Then
exterior angle = 2x - 2 = 2(47) - 2 = 94 - 2 = 92°
The probability would be 6/16 or 37.5% because there are 16 coins in total and 6 of them are worth more than 5 cents
Hope this helps!!!!
Answer:
2
Step-by-step explanation:
Given the average rate of change formula, we must first find the x and y values of the function.
We are provided with the two x values, 1 and 2. We now need to find the output, or y.
ƒ(x)=3^x-4x
ƒ(1)=3-4=-1
ƒ(2)=9-8=1
Then, we use the formula (ƒ(2)-ƒ(1))/x2-x1(subscripts here, in case you multiplied) which gets us 2/1, or 2. Therefore, the average rate of change(ARC) is 2. I believe you just need to find the output and subtract if they are exactly one whole number apart, but don't quote me on that.
First, set up a proportion.
![\frac{x}{12} = \frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B12%7D%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
Then, cross multiply and solve.
![36=4x36/4=99=x](https://tex.z-dn.net/?f=36%3D4x%3C%2Fp%3E%3Cp%3E36%2F4%3D9%3C%2Fp%3E%3Cp%3E9%3Dx)
Olá!
(2x - 6) + (x+ 10) + (2x + 1) = 180
2x - 6 + x + 10 + 2x + 1 = 180
2x + x + 2x = 180 + 6 - 10 - 1
5x = 175
x = 35
