The one all the way to the left matches with 1/7

1/18 matches with 0.05

0.5 matches with square root of 0.25

2/3 matches with 0.6

That's all I can help with.

A $900 notebook computer is discounted 5% what is the sale price of a notebook computer

fenix001 [56]

The sale price of computer is $855

Step-by-step explanation:

First of all the discount is calculated and then subtracted from the original price to calculate the sale price

Given

price of notebook computer = $900

Discount = 5%

So,

$Discount = 5\%\ of\ 900\\= 0.05 * 900\\= \$45$

Now,

$Sale\ price = Original\ price - Discount\\= 900-45\\=855$

Hence,

The sale price of computer is $855

Yes, I also happen to go to RSM. (6b)

Equation: 7x+2(15-x)=5*15

7x+(2)(15)+(2)(−x)=(5)(15)

7x+30+(−2x)=75

(7x+(−2x))+(30)=75

5x+30=75

5x=45

Now, calculate the sugar candies.

15-9=6lb sugar candies

Simplify: A fraction. The numerator is the fourth root of x cubed. The denominator is the cube root of x squared.

Anarel [89]

First it would be helpful to remove the radicals found in the numerator and denominator. We can do this by the property $\sqrt[n]{x^m} = x^{\frac{m}{n}}$ .

This means that our fraction now becomes:

$\dfrac{x^{\frac{3}{4}}}{x^{\frac{2}{3}}}$

Now, we can subtract the exponents of $x$ because of the fact that the numerator and denominator both have a base of $x$ :

$x^{\frac{3}{4} - \frac{2}{3}}$

$x^{\frac{1}{12}}$

Our answer is $\boxed{x^{\frac{1}{12}}}$ .
