Nancy has $4,111 in an account that pays 3.07% interest compounded monthly. What is her

soldier1979 [14.2K]

Answer:

Ending balance after 2 years=$4,370.98

Step-by-step explanation:

To calculate her ending balance after two years, we need to get the express the total amount as follows;

A=P(1+r/n)^nt

where;

A=Total future value of the initial investment

P=Initial value of the investment

r=Annual interest rate

n=number times the interest rate is compounded annually

t=number of years of the investment

In our case;

P=$4,111

r=3.07%=3.07/100=0.0307

n=12

t=2 years

Replacing;

A=4,111(1+0.0307/12)^(12×2)

A=4,111(1.0026)^24

A=4,370.98

Ending balance after 2 years=$4,370.98

What is the measure of ∠ADC in quadrilateral ABCD?

Andreyy89

we know that

The quadrilateral ABCD is a isosceles trapezoid. The properties of the isosceles trapezoid are as follows:

-The lower base angles are congruent.

m∠A=m∠D

m∠B=m∠C

m∠A+m∠B= $180$ °

m∠D+m∠C= $180$ °

therefore

m∠D=m∠A= $115$ °

m∠B= $180$ -m∠A

m∠B= $180$ - $115$

m∠B= $65$ °

m∠C=m∠B= $65$ °

the answer is

The measure of angle ADC is $115$ °

There are 13 angles.
We know that $m\angle4=112$ and $m\angle12=105$ (11 angles)

1.

$m\angle2+m\angle3+m\angle4=180\qquad\qquad\text{linear angles}\\\\m\angle3+m\angle3+m\angle4=180\qquad\qquad m\angle2=m\angle3\\\\2m\angle3+m\angle4=180\\\\2m\angle3+112=180\\\\2m\angle3=180-112\\\\2m\angle3=68\quad|:2\\\\\boxed{m\angle3=34=m\angle2}$

(9 angles)

2.

$m\angle3+m\angle12+m\angle11=180\qquad\qquad\text{triangle}\\\\34+105+m\angle11=180\\\\139+m\angle11=180\\\\m\angle11=180-139\\\\\boxed{m\angle11=41}$

(8 angles)

3.

$m\angle12+m\angle13=180\qquad\qquad\text{linear angles}\\\\105+m\angle13=180\\\\m\angle13=180-105\\\\\boxed{m\angle 13=75}$

(7 angles)

4.

$m\angle1+m\angle2+m\angle13=180\qquad\qquad\text{triangle}\\\\m\angle1+34+75=180\\\\m\angle1+109=180\\\\m\angle1=180-109\\\\\boxed{m\angle1=71}$

(6 angles)

5.

$m\angle9=m\angle11\qquad\qquad\text{vertical angles}\\\\\boxed{m\angle9=41}$

(5 angles)

6.

$m\angle10+m\angle11=180\qquad\qquad\text{linear angles}\\\\m\angle10+41=180\\\\m\angle10=180-41\\\\\boxed{m\angle10=139}$

(4 angles)

7. $a||b\text{ and } c||d$ so we have a parallelogram.

$m\angle4+m\angle5=180\qquad\text{consecutive angles are supplementary}\\\\112+m\angle5=180\\\\m\angle5=180-112\\\\\boxed{m\angle5=68}$

(3 angles)

$m\angle8=m\angle5\qquad\qquad\text{opposite angels are congruent}\\\\\boxed{m\angle8=68}$

(2 angles)

8.

$m\angle7+m\angle8+m\angle9=180\qquad\qquad\text{triangle}\\\\m\angle7+68+41=180\\\\m\angle7+109=180\\\\m\angle7=180-109\\\\\boxed{m\angle7=71}$

(1 angle)

9.

$m\angle1+m\angle5+m\angle6=180\qquad\qquad\text{triangle}\\\\71+68+m\angle6=180\\\\139+m\angle6=180\\\\m\angle6=180-139\\\\\boxed{m\angle6=41}$
