Answer:
D) 20
Step-by-step explanation:
x^2 + (y - 2)^2=100
This can be rewritten as
(x-0)^2 + (y - 2)^2=10^2
This is in the form
(x-h)^2 + (y - k)^2=r^2
The radius is 10
The diameter is 2 times the radius
d = 2*r = 2*10 = 20
Answer:
50 Students
Step-by-step explanation:
24% = 0.24
12/total amount of students = 0.24
12/0.24 = total amount of students
total amount of students = 50
<em>Answer:</em>
<em>Step-by-step explanation:</em>
<h2><u><em>
21u²</em></u></h2>
The formula for the area of a parallelogram is base times height
so
x = 7 (base)
y = 5
h = 3 (height)
7 * 3 =
21u²
We have:
5(x + 7) = 85 |divide both sides by 5
x + 7 = 17 |subtract 7 from both sides
x = 10
Answer:
180/60
1 hour is 60 min and 3 times 60 is 180.
So it’s 180/60
Also 180/60 is 3
