Answer:

His son is 10 years old.

Step-by-step explanation:

Now Aaron's son is s years old, and Aaron is 3s years old.

In 10 years, Aaron's son will be s + 10 years old, and Aaron will be 3s + 10 years old.

In 10 years, Aaron's age will be twice the son's age.

3s + 10 = 2(s + 10)

3s + 10 = 2s + 20

s = 10

His son is 10 years old.

The estimate would be 2+3 5+2 and 6+1 so 577 you can also just round and do 250 +300= 550 +20=570

Two points in the Cartesian plane are A(2.00 m, −4.00 m) and B(−3.00 m, 3.00 m). Find the distance between them and their polar

Brrunno [24]

The distance between the two points is $d=8.6m$

The polar coordinate of A is $\left(4.47,296.57\right)$

The polar coordinate of B is $\left(4.24,135\right)$

Explanation:

The two points are $A(2,-4)$ and $B(-3,3)$

The distance between two points is given by,

$d=\sqrt{(2+3)^{2}+(-4-3)^{2}}\\d=\sqrt{(5)^{2}+(-7)^{2}}\\d=\sqrt{25+49}\\d=8.6$

Thus, the distance between the two points is $d=8.6m$

The polar coordinates of A can be written as $(Distance, tan^{-1} \frac{y}{x} )$

Distance = $\sqrt{x^{2} +y^{2} }$

Substituting $A(2,-4)$ , we get,

Distance = $\sqrt{2^{2} +(-4)^{2} }=\sqrt{4+16 }=4.47$

$tan^{-1} \frac{y}{x} =tan^{-1} \frac{-4}{2}=-63.43$

To make the angle positive, let us add 360,

$\theta=360-63.43=296.57$

The polar coordinate of A is $\left(4.47,296.57\right)$

Similarly, The polar coordinate of B can be written as $(Distance, tan^{-1} \frac{y}{x} )$

Distance = $\sqrt{x^{2} +y^{2} }$

Substituting $B(-3,3)$ , we get,

Distance = $\sqrt{(3)^{2}+(3)^{2}}=4.24$

$tan^{-1} \frac{y}{x} =tan^{-1} \frac{3}{-3}=-45$

To make the angle positive, let us add 360,

$\theta=180-45=135^{\circ}$

The polar coordinate of B is $\left(4.24,135\right)$

velikii [3]

His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.

He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal

He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal

With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles

Your teacher has 36 carpet squares. She needs to make a new arrangement for the reading carpet. What are all of the different wa

stira [4]

Answer: The number of different ways she could arrange the carpet squares is 36!.

Step-by-step explanation:

We know that , the number of ways to arrange n things = n!

Given that , Your teacher has 36 carpet squares.

i.e. The total number of carpet squares = 36

If she needs to make a new arrangement for the reading carpet.

Then, the total number of arrangement of carpet squares would be 36!.

Hence , the number of different ways she could arrange the carpet squares is 36!
