Answer:
It is C, line KL has a slope of 0 and line MN is undefined and they're perpendicular
Step-by-step explanation:
Answer:
a/b = 2
so , a = 2b
b/c = 3/4
so , c = 4b/3
c/a = (4b/3) / 2b
which gives 2/3
Step-by-step explanation:
Since the exponents is positive, move the decimal 7 places to the right, thus giving you 12090000
Answer:
I would say the TRIANGLE because it has none of the lines that a symmetry has.
Part (a)
The radius is r = 42 because OA = 42.
The circumference, aka distance around the circle, is
C = 2*pi*r
C = 2*(22/7)*42
C = 264
We're told that arc AB is 110 mm which is 110/264 = 5/12 of the full distance around the circle.
So we'll apply 5/12 to the full rotation 360 to get (5/12)*360 = 150

Answer: 150 degrees</h3>
==============================================================
Part (b)
Compute the area of the full circle
A = pi*r^2
A = (22/7)*(42)^2
A = 5544
Then take 5/12 of this because we only want 5/12 of the full circle area (to get the area of the shaded pizza slice)
(5/12)*(5544) = 2310
<h3>Answer: 2310 square mm</h3>
==============================================================
Side note: Both answers are approximate because pi = 22/7 is approximate.
