Answer:

132 square centimeter

Step-by-step explanation:

Formula of a triangle: Area= base*height/2

Formula of a rectangle: Area=base * height

Triangle: base:8cm*height:3cm=24/2=12

Since there are two triangle that matches the same area, 12+12

Side Rectangle: base:6cm*height:5cm=30

Since there are two side rectangle with the same area, add 30+30

Bottom rectangle: base:6cm*height:8cm=48

Add all of them together:

12+12+30+30+48=132 square cm

Rodger put $1,000 in a bank account that pays 5% annual simple interest. At the end of four years, how much interest has he earn
Kryger [21]

Answer: He has earned $200 interest and the balance of his account is $1,200.

Step-by-step explanation:

Given: Principal : P = $1,000

Simple interest rate : r = 5% = 0.05

Time: t = 4 years

Simple interest = Prt

=1000\times0.05\times4=200

i.e. Simple interest = $200

Balance of account = Principal + Simple interest

=  $1,000 + $200

= $1,200

Hence, he has earned $200 interest and the balance of his account is $1,200.

Given sin0= 3/7, and tan0 <0, what is the value of coso?
spin [16.1K]

sin θ = 3 / 7 = .429

sin^2 θ + cos^2 θ = 1      trig identity

9/49 + cos^2 θ = 1

cos^2 θ = 40 / 49 = .816       cos θ = .903

Check .429^2 + .903^2 = 1

cos .903 = 25.4 deg

In the second quadrant sin = +, cos = -, tan = -

So 25.4 deg in the second quadrant = 180 - 25.4 = 154.6 deg

Check:

sin 154.6 = .428

cos 154.6 = -.903

tan 154.6 = -.475
