TiliK225 [7]3 years ago

8 0

Answer:

the interest is 960.

Step-by-step explanation:

the formula: I=prt i=interest p= pricipal [the money you start with]

r= rate t= time

I=? I= 800 (0.02) (10)

P= $800 I= 160+ 800 {because $160 is added}

R= 2% --> 0.02 [as a decimal] I= $960

T= 10 years

Triangles LMN and NWR are right triangles. What is

Sever21 [200]

Answer:

NW = 15.6 cm

Step-by-step explanation:

If ΔLMN ~ ΔNWR then:

$\sf LN : LM = RN : RW$

$\implies \sf \dfrac{LN}{LM}=\dfrac{RN}{RW}$

$\implies \sf \dfrac{10}{24}=\dfrac{6}{RW}$

$\implies \sf 10RW=6 \cdot 24$

$\implies \sf RW = 14.4\:cm$

Find NW by using Pythagoras' Theorem:

$a^2+b^2=c^2$

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

a = RN = 6 cm
b = RW = 14.4 cm
c = NW

Substituting the given values into the formula and solving for NW:

$\implies \sf 6^2+14.4^2=NW^2$

$\implies \sf NW^2=243.36$

$\implies \sf NW=\sqrt{243.36}$

$\implies \sf NW=15.6\:cm$

$Given: l=5 ~units , b=4 ~units,h=3 ~units$

$Area=2(5*4+4*3+3*5)$

$=2(20+12+15)$

$=2(47)$

$=94$

In ∆PTQ

Apply Pythagorean theorem

$\\ \tt\hookrightarrow PT^2=PQ^2+QT^2$

$\\ \tt\hookrightarrow PT^2=15.4^2+9.3^2=323.16$

$\\ \tt\hookrightarrow PT=17.9$

In ∆TRQ

$\\ \tt\hookrightarrow tan44.4=\dfrac{QT}{TR}=\dfrac{9.3}{TR}$

$\\ \tt\hookrightarrow 0.9=\dfrac{9.3}{TR}$

$\\ \tt\hookrightarrow TR=\dfrac{9.3}{0.9}=10.3$

PR=PT+TR=10.3+17.9=28.2cm

Now

Area:-

$\\ \tt\hookrightarrow 1/2bh$

$\\ \tt\hookrightarrow 1/2(28.2)(9.3)$

$\\ \tt\hookrightarrow 14.1(9.3)$

$\\ \tt\hookrightarrow 131.13cm^2$
