Answer:
22801
Step-by-step explanation:
#40
No. of terms = (301 + 1)/2
No. of terms = 302/2
No. of terms = 151
Now,
Sum = n²
Sum = (151)²
Sum = 22801
All we have to do is replace n with 4.
-6-4(4-1)
Parenthesis first.
-6-4×3
Multiplication next.
-6-12
Now subtract.
-18
The 4th term is -18.

Answer:
x = 10
Step-by-step explanation:
From what we can see in the diagram, the smaller triangle dimensions were dilated by a factor of 3
So to get the dimensions of the smaller from the bigger or larger triangle, we proceed to divide what we have on the larger triangle by 3
Kindly note that we do this for the comparable sides
Mathematically, we can have x as;
30/3 = 10
Answer:
The correct option is;
B. I and II
Step-by-step explanation:
Statement I: The perpendicular bisectors of ABC intersect at the same point as those of ABE
The above statement is correct because given that ΔABC and ΔABE are inscribed in the circle with center D, their sides are equivalent or similar to tangent lines shifted closer to the circle center such that the perpendicular bisectors of the sides of ΔABC and ΔABE are on the same path as a line joining tangents to the center pf the circle
Which the indicates that the perpendicular the bisectors of the sides of ΔABC and ΔABE will pass through the same point which is the circle center D
Statement II: The distance from C to D is the same as the distance from D to E
The above statement is correct because, D is the center of the circumscribing circle and D and E are points on the circumference such that distance C to D and D to E are both equal to the radial length
Therefore;
The distance from C to D = The distance from D to E = The length of the radius of the circle with center D
Statement III: Bisects CDE
The above statement may be requiring more information
Statement IV The angle bisectors of ABC intersect at the same point as those of ABE
The above statement is incorrect because, the point of intersection of the angle bisectors of ΔABC and ΔABE are the respective in-centers found within the perimeter of ΔABC and ΔABE respectively and are therefore different points.
Answer:
0.31% = 0.0031 in decimal form.
Step-by-step explanation:
Percent means 'per 100'. So, 0.31% means 0.31 per 100 or simply 0.31/100. If you divide 0.31 by 100, you'll get 0.0031 (a decimal number).
