The third choice.
The sides of the photo plus the margins of the border equal x.
It’d be 12.458 , rounded to the nearest tenth makes it 12.5. Hopefully, I helped.
Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²
so given
center at (9,-8)
(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²
input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r
well, the equation is
(x-9)²+(y+8)²=1000
Answer:
176 mm
Step-by-step explanation:
The circumference of a circle is the perimeter of a circle (length of a circle). The circumference of a circle is given as:
Circumference (C) = 2πr = πd, where d is the diameter
The circumference of a circle with diameter 7 mm is:
C = πd = 22/7(7) = 22 mm
The length of the paper to round the cylindrical pencil is the same as the perimeter of the pencil which is 22 mm.
To round the pencil 8 times, the length of the paper needed = 8 × 22 mm = 176 mm
Answer:
B. 8 times the difference of a number <em>z</em> and 6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Translate (z - 6)
<em>z </em>= a number <em>z</em>
- = difference
6 = six
(z - 6) = The difference between a number <em>z</em> and 6
Step 2: Translate 8(z - 6)
(z - 6) = The difference between a number <em>z</em> and 6
Since we are distributing the 8, we are multiplying.
8 times the difference of a number <em>z</em> and 6
