Answer:
106°
Step-by-step explanation:
Given that the points B, C and D are colinear, it means that
2x + 40 = 5x + 10
collecting like terms
40 - 10 = 5x - 2x
3x = 30
x = 10
Hence the angle ∠E
= 5(10) + 10
= 60°
∠BCE = X + 4
= 10 + 4
= 14°
Given that the sum of angles in a triangle is 180°
∠D + 14 + 60 = 180
∠D = 180 - 74
= 106°
Answer:
1. 9461000000000
move the desimal in 9.461 12 places to the right to get:
9461000000000
2.
5.85 x 10^-3,
2.5 x 10^-1,
3.6 x 10^8,
8.5 x 10^8,
8.5 x 10^12
the smallest exponent is the smallest. Since 8.5 x 10^8 and 3.6 x 10^8 have the same exponent, go to the desimal
To solve this problem, plug 8250 in for b and 15 in for t and then solve for k:
<em>*Divide both sides by 1000*</em>
<em>*Take the natural log (ln) of both sides*</em>
2.1102=15k
<em>*Divide both sides by 15*</em>
0.1406=k
0.1406 rounds to 0.141 which is close to a. 0.143.
Hope this helps!!
I believe it is d: whole numbers, integers, and rational numbers
