I’m pretty sure 17.3 because of you do a^2+b^2=c^2 you get a^2= 10 square root 3 and that in a decimal is 17.3205
Answer:
![5+\frac{n}{2}=11](https://tex.z-dn.net/?f=5%2B%5Cfrac%7Bn%7D%7B2%7D%3D11)
![n=12](https://tex.z-dn.net/?f=n%3D12)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Translate the sentence into an equation using n as the unknown number. Then solve the equation for n.
5 increased by half a number is 11
Let
n ----> the unknown number
we know that
The linear equation that represent this situation is
![5+\frac{n}{2}=11](https://tex.z-dn.net/?f=5%2B%5Cfrac%7Bn%7D%7B2%7D%3D11)
solve for n
Multiply by 2 both sides
![10+n=22](https://tex.z-dn.net/?f=10%2Bn%3D22)
subtract 10 both sides
![n=22-10](https://tex.z-dn.net/?f=n%3D22-10)
![n=12](https://tex.z-dn.net/?f=n%3D12)
We are given equation: 34b−23b=−9.
We can see 34b and 23b both has b's with them.
So, we can combine like terms.
Comining means addition or subtaction.
We have minus sign in between 34b and 23b.
So, we need to subtract 34b and 23b.
On subtracting, we get
11b.
Therefore, we get
11b = -9.
Now, we need to divide by 11 on both sides. We get on dividing
b = -9/11.
Therefore, -9/11 can be enter in the boxes to write an equation that is equivalent to 34b−23b=−9.

Answer:
14.09 square units
Step-by-step explanation:
The desired area is the area of the full circle, multiplied by the fraction that is shaded. That fraction is the ratio of the sector central angle to the central angle for a whole circle: 42°/360°.
A = πr²(d/360)
A = 3.14159(6.2²)(42/360) ≈ 14.09
The area of the shaded sector is about 14.09 square units.
