Answer:

Simple interest at 2.1%

Step-by-step explanation:

If you had $200 to start

Simple would be $200 x 2.1% = $4.2

$4.2x3 years = $12.60

Total money after 3 years $212.60

Compound would be $200 x 2.7% = $5.40 1st year

$205.40 x 1.4% = $2.8756 (2.88 rounded) 2nd year

$208.28 x 1.4% = $2.9159 (2.92 rounded) 3rd year

3 years total = $211.20

$212.60 greater then $211.20

Consider the 30°-60° right triangle shown whose hypotenuse is equal to one. Clearly this triangle is half of an equilateral tria

Bad White [126]

Answer:

Step-by-step explanation:

Given triangle ABC is a right triangle.

m∠ACB = 60°

m∠CAB = 30°

m(AC) = 1 unit

A). Shorter side of the given triangle = Side BC

By applying cosine rule,

cos(∠C) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(60°) = $\frac{BC}{AC}$

BC = $\frac{1}{2}(AC)$

BC = $\frac{1}{2}$

Length of the shorter side = 0.5 units

B). Longer side of the given triangle = side AB

By applying Pythagoras theorem in the given triangle,

AC² = AB² + BC²

1² = AB² + $(\frac{1}{2})^2$

1 = AB² + $\frac{1}{4}$

AB = $\sqrt{1-\frac{1}{4}}$

AB = $\sqrt{\frac{3}{4}}$

AB = $\frac{\sqrt{3} }{2}$

Length of the longer side = $\frac{\sqrt{3}}{2}$

Verifique se os numeros 15,20 e 30 sao diretamente proporcionais aos numeros 24,32 e 48

Vikki [24]

We are given to check

whether these numbers are proportional

we know that any set of numbers are proportional when their ratios are equal

so, firstly we will ratios

First set of numbers:

We are given first set of numbers as 15 , 20 and 30

so, it's ratio is

$15:20:30$

now, we can simplify it

$5\times 3:5\times 4:5\times 6$

Since, common factor is 5

so, we can cancel 5

and we get

$3:4:6$

Second set of numbers:

We are given first set of numbers as 24 , 32 and 48

so, it's ratio is

$24:32:48$

now, we can simplify it

$8\times 3:8\times 4:8\times 6$

Since, common factor is 8

so, we can cancel 8

and we get

$3:4:6$

We can see that both sets of numbers are having same ratios

so, they are proportional.........Answer
