Write the expanded notation for 15,729?

pshichka [43]

Step-by-step explanation:

15,729 = 10 000 + 5 000 + 700 + 20 + 9

= (1 x 10000) + (5 x 1000) + (7 x 100) + (2 x 10) + (9 x 1)

We can also write it like this :

(1 x 10⁴) + (5 x 10³) + (7 x 10²) + (2 x 10¹) + (9 x 10⁰)

Two complementary angles are represented by x and x+14 . find the value of x

qaws [65]

Answer:

$x=38\textdegree$

Step-by-step explanation:

Remember that complementary angles <em>always </em>add up to 90°.

We know that the two complementary angles are represented by (x) and (x+14). In other words:

$(x)+(x+14)=90$

So, let's solve for x.

First, combine like terms:

$2x+14=90$

Let's isolate the x by subtracting 14 from both sides:

$(2x+14)-14=(90)-14$

The left cancels. Subtract on the right:

$2x=76$

Divide both sides by 2:

$\frac{2x}{2}=\frac{76}{2}$

The left side cancels. Divide on the right:

$x=38\textdegree$

So, the value of x is 38°.

And we're done!

Answer:

3. 3 : 5; 3: 5

Step-by-step explanation:

First, let's find the leght of the sides of each octagon.

$A= 18in^{2}$

The area of an octagon is defined by

$A=2(1+\sqrt{2})l^{2}$

Replacing the area

$18=2(1+\sqrt{2})l^{2}\\\frac{18}{2(1+\sqrt{2})} =l^{2}\\l=\sqrt{\frac{18}{3.4} } \approx 2.3 \ in$

Therefore, the side of the first octagon is 1.6 inches long.

Its perimeter is: $P=8(2.3in)=18.4in$

$A=50 in^{2}$

$50=2(1+\sqrt{2})l^{2}\\\frac{50}{2(1+\sqrt{2})} =l^{2}\\l=\sqrt{\frac{50}{3.4} } \approx 3.8 \ in$

Therefore, the side of the second octagon is 3.8 inches long.

Its perimeter is $P=8(3.8in)=30.4in$ .

Now, let's divide to find each ratio:

$\frac{3.8}{2.3} \approx 1.65$ (the ratio between sides).

$\frac{30.4}{18.4} \approx 1.65$ (the ratio between perimeters).

Therefore, the closest ratio is 3. 3 : 5; 3: 5
