How does 1/8 divided by 1/4 equal 1/2?

1 answer:

6 0

When you divide a fraction by a fraction, you're really just multiplying by a reciprocal. A reciprocal is the fraction flipped around.
So, 1/8 <span>÷ 1/4 is the same thing as 1/8 x 4/1
Now, you just multiply. 1 times 4 is 4. 8 times 1 is 8.
1/8 x 4/1=4/8
4/8 simplified is 1/2
So that is how 1/8</span><span>÷1/4=1/2</span>

The area of a square shaped yard is 201.5 ft2. Which measurement is closest to the side length of this yard in feet?

Aleonysh [2.5K]

Answer:

a = 14.19 feet

Step-by-step explanation:

Given that,

The area of a square shaped yard is 201.5 ft²

We need to find the side length of this yard in feet.

The area of a square shaped object is given by :

A = a², a is the side length of the object

Put A = 201.5 ft² in above formula,

$201.5=a^2\\\\a=\sqrt{201.5 } \\\\a=14.19\ \text{feet}$

So, the side of the square yard is 14.19 feet.

How do solve angle PRQ and angle QRS

ruslelena [56]

PRQ and QRS should add to PRS

(3x-8)+(2x+6)=98
5x-2=98
5x=100
x=20

Plug 20 into both expressions:
3(20)-8
60-8
52 degrees= PRQ. <===========

2(20)+6
40+6
46 degrees= QRS. <==========

Rearranging literal equations!! really confused ASAPplease

valina [46]

Answer:

b = $\frac{8a-55}{5-a}$

Step-by-step explanation:

To clear the radicals square both sides

$\frac{1}{6-a}$ = $\frac{8+b}{b-7}$ ( cross- multiply )

(6 - a)(8 + b) = b - 7 ← expand factors on left using FOIL

48 + 6b - 8a - ab = b - 7 ( subtract 48 from both sides )

6b - 8a - ab = b - 55 ( add 8a to both sides )

6b - ab = b - 55 + 8a ( subtract b from both sides )

6b - ab - b = 8a - 55, that is

5b - ab = 8a - 55 ← factor out b from each term on the left side )

b(5 - a) = 8a - 55 ← divide both sides by (5 - a)

b = $\frac{8a-55}{5-a}$
