240 total
We know-
150=62.5
x = 100
Cross multiply
15,000=62.5x
/62.5 = /62.5
240 = x

Answer:

Sum of all three angles inside a triangle = 180°

Total number of parts = 3 + 10 + 7 = 20

Each part = 180 ÷ 20 = 9

Let us name the three angles of this triangle as ∠1 , ∠2 and ∠3 respectively .

Number of parts for ∠1 = 3 parts

∠1 = 3 × 9 = 27°

Number of parts for ∠2 = 10 parts

∠2 = 10 × 9 = 90°

Number of parts for ∠3 = 7 parts

∠3 = 7 × 9 = 63°

The three angles of this triangle measure 27° , 90° and 63° respectively

Measure of the smallest angle = 27°

Therefore , the measure of the smallest angle = 27° .

Convert the integral below to polar coordinates and evaluate the integral.

White raven [17]

I suppose the integral is

$\displaystyle\int_0^5\int_y^{\sqrt{25-y^2}} xy\,\mathrm dx\,\mathrm dy$

The integration region corresponds to a sector of a cirlce with radius 5 subtended by a central angle of π/4 rad. We can capture this region in polar coordinates by the set

$R=\left\{(r,\theta)\mid0\le r\le5,0\le\theta\le\dfrac\pi4\right\}$

Then $x=r\cos\theta$ , $y=r\sin\theta$ , and $\mathrm dx\,\mathrm dy=r\,\mathrm dr\,\mathrm d\theta$ . So the integral becomes

$\displaystyle\iint_Rxy\,\mathrm dx\,\mathrm dy=\int_0^{\pi/4}\int_0^5r^3\sin\theta\cos\theta\,\mathrm dr\,\mathrm d\theta=\frac{625}{16}$

Answer:

Amount ($451.9), Interest ($51.9)

Step-by-step explanation:

We need to use the formula of A = P(1 + $\frac{r}{n}$ )^n*t

A = Total Amount

P = Principle/Deposited money

R = Annual Interest Rate

N = Number of times compounder per year

T = time in years

We have P = $400, r = 2.47%, n = 1 and t = 5 years.

Now lets plug it all in!

$A = 400 (1 + \frac{0.0247}{1})^{1*5}$

$A = 400 * 1.0247^5$

$A = 400 * 1.129753$

A = 451.9

Now we need to find the interest...

We will use A = P + I since A is 451.9 and P = 400

451.9 = 400 + I

I = 451.9 - 400

I = 51.9
