Answer:

I=\$11,911.23

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the amount that she will repay  

P is the amount borrowed  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=20\ years\\ P=\$10,000\\ r=0.04\\n=1  

substitute in the formula above  

A=10,000(1+\frac{0.04}{1})^{1*20}  

A=10,000(1.04)^{20}  

A=\$21,911.23  

Find out the interest

I=A-P

substitute the values

I=\$21,911.23-\$10,000=\$11,911.23

<h3>Answer:  The flagpole is <u>16 feet tall</u></h3>

==========================================================

Explanation:

The small markings for the angles in the diagram help us see how the angles pair up and how those pairs are congruent.

The square angle markers indicate we have 90 degree angles (aka right angles). That's one pair of congruent angles.

The other pair are the angles marked with small curves. We don't need to worry about the angle measure of these. All we care about is we have a second congruent pair of angles.

Having 2 sets of congruent angles allows us to use the AA (angle angle) similarity theorem.

The similar triangles allow us to set up the proportion below and isolate x.

-------------------

Let's solve for x.

6/x = 4.5/12

6*12 = x*4.5

72 = 4.5x

4.5x = 72

x = 72/(4.5)

x = 16

The flagpole is 16 feet tall.

This is somewhere between a 1 and 2 story building in terms of height.

In the diagram below, mpr = 140 and mqs = 106. What is the measure of ptr?
choli [55]

Answer:

Option B

m\angle PTR=123^o

Step-by-step explanation:

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

so

m\angle PTR=\frac{1}{2}[arc\ PR+arc\ QS]

substitute the given values

m\angle PTR=\frac{1}{2}[140^o+106^o]

m\angle PTR=123^o

I need help please.
JulijaS [17]

Answer:

\frac{7\sqrt{5} }{8}

Step-by-step explanation:

Using the rules of radicals

\sqrt{\frac{a}{b} } = \frac{\sqrt{a} }{\sqrt{b} }

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

\sqrt{\frac{245}{64} } = \frac{\sqrt{245} }{\sqrt{64} }

Simplifying the radicals

\sqrt{245}

= \sqrt{5(7)(7)}

= \sqrt{49(5)}

= \sqrt{49} × \sqrt{5} = 7\sqrt{5}

and

\sqrt{64} = 8

The simplified radical is

\frac{7\sqrt{5} }{8}
