Answer:
The answer is X=6 ABC=30 CBD=30
Answer:
x = 21
ABC = 105
CBD = 75
Step-by-step explanation:
3x + 12 + 5x = 180
8x + 12 = 180
8x = 168
x = 21
3(21) + 12 = 75
5(21) = 105

A,E, and D are collinear. BCDE is a parallelogram. Find m
Answers
Answer:
B. 29º
Step-by-step explanation:
Given that BCDE is a parallelogram, then [tex]BE \parallel CD[/tex] and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:
[tex]\angle D = \angle E = 51^{\circ}[/tex] (1)
In addition, the sum of internal angles in triangles equals 180º, which implies that:
[tex]\angle A + \angle B + \angle E = 180^{\circ}[/tex] (2)
If we know that [tex]\angle B = 100^{\circ}[/tex] and [tex]\angle E = 51^{\circ}[/tex], then [tex]\angle A[/tex] is:
[tex]\angle A = 180^{\circ}-\angle B - \angle E[/tex]
[tex]\angle A = 180^{\circ}-100^{\circ}-51^{\circ}[/tex]
[tex]\angle A = 29^{\circ}[/tex]
Hence, correct answer is B.

The answer would be be 29 degrees

Samuel is going to invest $4,900 and leave it in an account for 14 years. Assuming the

would be required in order for Samuel to end up with $10,300?

Answer:
Submit Answer
Answers
Answer:
0.053
Step-by-step explanation:
Using the compound formula A=P(1+r/n)^nt we can plug in the numbers we know. A being the total, P the initial amount, n is the number of compounds in a year, and t is the number of years passing. So 10300= 4900(1+ r/12)^12(14). We have to isolate r in order to find the rate. We can divide both sides by 4900, giving us 103/49= (1+ r/12)^168. Then we take the 168 square root from both sides. 1.00443… = 1 + r/12. Subtract 1 from both sides. 0.00443… = r/12. Then multiply both sides by twelve . r= 0.053

A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi
Answers
Answer:
15 inches.
Step-by-step explanation:
V = 1/3 pi r^2 h
7065 = 1/3 * 3.14 * 30 * r^2
r^2 = 7065 / (1/3 * 3.14 * 30)
r^2 = 7065 / 31.4 = 225
r = sqrt 225 = 15.

the 100th term of the sequence with the term -1-4n
Answers
Given:
The terms of a sequence are given by
[tex]a_n=-1-4n[/tex]
To find:
The 100th term of the sequence.
Solution:
We have,
[tex]a_n=-1-4n[/tex]
Putting n=100, we get
[tex]a_{100}=-1-4(100)[/tex]
[tex]a_{100}=-1-400[/tex]
[tex]a_{100}=-401[/tex]
Therefore, the 100th term of the given sequence is -401.
