B) 36 kg in the ratio 1:3:5

ale4655 [162]

9514 1404 393

Answer:

4 kg : 12 kg : 20 kg

Step-by-step explanation:

The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...

(36 kg)/9 = 4 kg

Multiplying the given ratio by 4 kg will show the appropriate division:

1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg

What is the value of AAA when we rewrite \left(\dfrac {6}{17}\right)^{9x}( 17 6 ) 9x (, start fraction, 6, divided by, 17, end

sineoko [7]

We have been given an expression $\left(\dfrac {6}{17}\right)^{9x}$ . We are asked to find the value of A when rewrite our given expression as $A^{x}$ .

To solve our given problem, we will use exponent properties.

Using exponent property $a^{mn}=(a^m)^n$ , we can rewrite our given expression as:

$\left(\dfrac {6}{17}\right)^{9x}=\left(\left(\dfrac {6}{17}\right)^9\right)^{x}$

Now, we will compare our expression with $A^{x}$ .

Upon comparing $\left(\left(\dfrac {6}{17}\right)^9\right)^{x}$ with $A^{x}$ , we can see that $A=\left(\dfrac {6}{17}\right)^9$ .

Therefore, the value of A is $\left(\dfrac {6}{17}\right)^9$ .

We can further simplify $\left(\dfrac {6}{17}\right)^9$ as:

$\left(\dfrac {6}{17}\right)^9=\frac {6^9}{17^9}=\frac{10077696}{118587876497}$

Taylor is making a mini apple pie with a radius of 3.14 in for her math class. what is the area of her mini pie?

artcher [175]

So First of all we need to know how to find the area of a circle.

Assuming that the apple pie is the shape of a circle

The formula for area is $\pi$ $r^{2}$

Well we know that the radius = 3.14

And we know that $\pi$ = 3.14 as well.

All we have to do is multiply..

3.14 x $3.14^{2}$ = 30.95

So the area of the pie is 30.95 in

Good Luck! :)

You increase the size of a page by 30%. Then you decrease it by 30%. What is the size of the page now?

kotegsom [21]

Lets use 1 to solve this problem because it is easiest to show.

Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).

Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)

Therefore the page had a 9% reduction from its original size or is 91% of its original size.
