Answer:
144°
Step-by-step explanation:
First, find the area of the circle, with the formula A = 
r²
Plug in 10 as the radius, and solve
A = r²
A = (10²)
A = 100
Using this, create a proportion that relates the area of the sector to the degree measure of the arc.
Let x represent the degree measure of the arc of the sector:
= 
Cross multiply and solve for x:
100x = 14400
x = 144
So, the degree measure of the sector arc is 144°
I hate study island lol and are those supposed to be powers? Like 3 to the power of 8
Answer:
C. (-4x^2)+2xy^2+[10x^2y+(-4x^2y)
Step-by-step explanation:
A. [9-4x2) + (-4x2y) + 10x2y] + 2xy2 : in this polynomial the first term is not a like term, then this is incorrect.
B. 10x2y + 2xy2 + [(-4x2) + (-4x2y)] : in this polynomial, the terms that are grouped, are not like terms, then is incorrect.
C. (-4x2) + 2xy2 + [10x2y + (-4x2y)] ; This polynomial is the right answer because the like terms are grouped.
D. [10x2y + 2xy2 + (-4x2y)] + (-4x2): This polynomial is incorrect because one of the terms that are grouped is not a like term.
Oh um... well let's see... okay I do NOT know this. SO sorry. Hope you get an answer soon.
Answer:
False
Step-by-step explanation:
Given
Required
True or False
The above numeral can be split as follows:
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
In Roman numerals;
Substitute 40 for XL and 4 for IV.
Hence;
<em /><em> is false</em>
