Answer:
16.7
Step-by-step explanation:
We can use the Pythagorean theorem, a^2 + b^2 = c^2.
a = 11
c = 20
11^2 + b^2 = 20^2
121 + b^2 = 400
b^2 = 279
b = sqrt(279) = 16.7
Answer:
Step-by-step explanation:
Jada is making circular invitations
we have d=12 cm, the radius r=6
she needs to find out the circumference
C=2x3.14x r
C=2x 3.14x6=37.68
180/37.68=4.77
she can make just 4 invitations
Answer:
$12 per hour
Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: 
Let's use the points (1, 27) and (2, 39) in the expression:

Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
I hope this helps :)
Answer:
B
Step-by-step explanation:
When looking at the number line, we can see the distance between A and B is one unit
A |-2| + |-1| = 2+1 =3 That is not 1 unit
B 2-1 =1 that is 1 unit
C -2 + -1 = -3 that is not 1 unit
D |-1| - (-2) = 1 + 2 =3 that is not 1 unit
Even though it says all expressions, there is only 1 that shows a distance of 1 unit
