Which method is valid for proving that two circles are similar?

Mathematics

tatuchka [14]3 years ago

'a',  'c', and  'd'  are true for any two circles.  That's because
ALL circles are similar.  You don't need to prove it.  The question
is weird.

Find the area of the shape above ?
Juli2301 [7.4K]

Area of triangle = <em>A(t) </em>= 1/2(base x height)

Area of square = <em>A(s) = </em>base x height

<em>A(s) </em>= 2 x 2 = 4

<em>2(A(s))</em> = 2(1/2(2)(2) = 2(1/2(4)) = 2(2) = 4

Add the two areas together

4 + 4 = 8

8 units² is your answer

25 is 36% of what number
ch4aika [34]

Answer:

x = 69.44

Step-by-step explanation:

We have, 36% × x = 25

or, 36/100 × x = 25

Multiplying both sides by 100 and dividing both sides by 36,

we have x = 25 × 100/36

x = 69.44

If you are using a calculator, simply enter 25×100÷36, which will give you the answer.

Stan has made a $125.30 monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years. He would now
MissTica
The future value of a monthly deposit A=125.30 at annual interest i=0.015 per annum for n=35 years compounded monthly is given by
FV=A((1+i/12)^(12*n)-1)/(i/12)
=125.30(1+0.015/12)^(12*35)/(0.015/12)
=$69156.05

The annuity formula is given by
Payment = r(PV)/(1-(1+r)^(-n))
where
r=interest rate per period = 0.015/12
PV= $69156.05
n=20*12=240
so
Payment = (0.015/12)<span>69156.05/(1-(1+0.015/12)^(-240))
= $333.71  per month.</span>
