     7x^2 + 11x - 6
--------------------------
    7x^2 - 10x + 3

        (7x - 3)(x + 2)
=  -----------------------
        (7x - 3)(x  - 1)
             
        x + 2
=  --------------

Answer:

\frac{(x-\frac{3}{7})(x+2)} {(x+\frac{2}{7})(x-1)}

Explanation:

We have been given the expression\frac{7x^2+11x-6}{7x^2-10x+3}

given two expressions are quadratic

Using the formula to solve the quadratic equation is

D=b^2-4ac

Now, to solve the equation for x where

x=\frac{-b\pm\sqrt{D}} {2a}

general quadratic equation is ax^2+bx+c

Comparing the numerator and denominator with general quadratic expression we will get

a=7,b=11,c=-6 in numerator

And a=7,b= -10,c=3 in denominator

And after substituting the values we will get

D=289 for numerator

and x=\frac{-11\pm17}{14} \\\\\Rightarrow\frac{3}{7} ,-2

And D=16 in denominator

and x=\frac{-(-10)\pm4}{14} \\\\\Rightarrow\frac{-2}{7} ,1

finally we will get \frac{(x-\frac{3}{7})(x+2)} {(x+\frac{2}{7})(x-1)}

441 is 63% of what number
blagie [28]
<span>Question: 441 is 63% of what number?
=> 63% = 63% / 100% = 0.63
Since 441 is the 63% let’s find the value of 37% to get the toal of 100%
Solution, follow the formula
=> 0.63x = 441 – where x will be the value of the missing 100% value.
=> x = 441 / 0.63
=> x = 700 – the 100% value that have 441 as 63%
let’s check if we have the correct answer:
=> 700 * .63 = 441 </span>

10. A road roller takes 750 revolutions to move once to
GarryVolchara [31]

Answer:

Step-by-step explanation:

Use consistent units. The length of the roller is 2.8 m. The diameter is 168 cm = 1.68 m

Circumference of roller = 1.68π m

Contact area of roller = 1.68π × 2.8 = 4.704π m²

Each rotation levels 4.704π m² of the playground.

Area of playground = 750 rotations × (4.704π m²)/rotation

= 3528π m²

≈ 11,084 m²

(a) Find the remainder when 15! is divided by 17. (b) Find the remainder when 2(26!) is divided by 29, Thatermine whether 17 is
dlinn [17]

Answer:

Step-by-step explanation:

a) We have 15! as the product of 1 to 15 natural numbers.  Since 17 is prime there will be no factor common to these

By actual division we find

15! (mod 17) =16

From this we deduce

even 16! mod 17 = 16 = -1

According to Wilson theorem

(17-1)! = -1 mod 17

Thus verified 17 is prime

Hence 15! (mod 17) =-1=16

-----------------------

b) 2(26!) is divided by 29

Since 29 is prime

(29-1)! = -1 mod 29

28! = -1 mod 29 = 28

When divided this gives 25 as remainder
