Answer:

Bro i dont know if i am right but here we go

The answer most likely is 80

Step-by-step explanation:

By useing a bit of geometry instead of useing two angles to find your last angle.

So first notice how there are two of the same sides (14)but one differnt side(18) okay nice

With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.

So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80

I hope you understand and im sorry if this is wrong.

The sum of the reciprocal of two consecutive odd integers is 44/483.Write a rational equation to solve the problem.

Arturiano [62]

Answer:

Step-by-step explanation:

Let consecutive odd integers be (2x + 1) and (2x + 3)

Their reciprocals are $\frac{1}{2x + 1 }$ and $\frac{1}{2x + 3 }$

$\frac{1}{2x+1}+\frac{1}{2x+3}=\frac{44}{483}\\\\\frac{1*(2x+3)}{(2x+1)(2x+3)}+\frac{1*(2x+1)}{(2x+3)(2x+1)}=\frac{44}{483}\\\\\frac{2x + 3 + 2x +1}{(2x + 1)(2x+3)}=\frac{44}{483}\\\\\frac{4x + 4}{4x^{2}+8x+3}=\frac{44}{483}\\$

483*(4x+4) = 44*(4x² + 8x + 3)

483*4x + 483*4 = 44*4x² + 44*8x + 44*3

1932x + 1932 = 176x² + 352x + 132

176x² + 352x + 132 -1932x - 1932 = 0

Combine like terms

176x² + 352x - 1932x - 1932 + 132 = 0

176x² - 1580x - 1800 = 0

Divide the equation by 4

44x² - 395x - 450 = 0

$3 \frac{1}{2} r = 28 \\ \frac{7}{2} r = 28 \\ \frac{ \frac{7}{2} }{ \frac{7}{2} } r = \frac{28}{ \frac{7}{2} } \\ r = \frac{ \frac{56}{2} }{ \frac{7}{2} } \\ r= \frac{56}{7}$

$1 \frac{1}{2} c =6 \\ \frac{3}{2} c= \frac{12}{2} \\ \frac{ \frac{3}{2} }{ \frac{3}{2} } c= \frac{ \frac{12}{2} }{ \frac{3}{2} } \\ c= \frac{ \frac{12}{2} }{ \frac{3}{2} } = \frac{12}{3} =4 \\ c=4$

Miguel deposits 680.00 in an account that pays 3.5% simple interest. if he neither adds more money nor withdraws any money, what

quester [9]

I=PRT
I=interst
P=invested amount
R=rate in decimal
T=time in years

given
P=680
R=3.5%=0.035
T=6

I=680*0.035*6
I=142.8
that is interest

total is interest+principal=680+142.8=822.8

after 6 years, $822.80 is in the account
