[tex]827 \times 4 \approx820 \times 4[/tex]

[tex]820 \times 4 = 800 \times 4 + 20 \times 4 \\ 820 \times 4 = 3200 + 80 \\ 820 \times 4 = 3280[/tex]

[tex]827 \times 4 \approx3280[/tex]

In reality it's just that additional 4 sevens,so

[tex]827 \times 4 = 820 \times 4 + 4 \times 7 \\ 827 \times 4 = 3280 + 28 \\ 827 \times 4 = 3308[/tex]

Answer:

-2.886

Step-by-step explanation:

4.1/3y+9=12

41/10/3y+9=12

41/10=12(3y+9)

41/10=36y+108

41=10(36y+108)

41=360y+1080

41-1080=360y

-1039=360y

y= -1039/360

y= -2.886

The price of small box of tangerines is $14.43 approx. and price of large box of tangerines is $ 17

Let the price of small boxes be x and the price of large boxes be y

we need to form a linear equation in two variable

So, Kayla's equation is

7x + 4y = 166

and Shawna's equation is

7x+ 3y = 149

Subtracting equation 2 from equation 1

 7x + 4y = 166

(-) 7x +3y = 149

we get y = 17

Now substituting the value of y in equation 1

7x + 4(17) = 169

7x +68 = 169

7x = 101

x= 14.428

Hence, The price of small box of tangerines is $14.43 approx. and price of large box of tangerines is $ 17

Converting the given radicals into their exponential forms, √x³ / ³√x² = ⁶√x⁵

When work with radical numbers, sometimes it is easier to express them in exponential form first.

Recall the rules of exponent operations:

Note that the first 3 rules use the same base. If there are more than 1 base number, then group the exponent that have the same base first.

Example:

Tips: To simplify exponent numbers, sometimes it is useful to modify the base whenever possible.

The three digit number is 727 while the one digit number is 4

Given data

The sum of a three-digit number and a one-digit number is 731.

The product of the numbers is 2,908

let three digit number be x, y, and z

let the one digit be w

The sum

xyz + w =731

xyz * w = 2,908

making xyz the subject of formula

xyz = 731 - w

plugging in xyz into xyz * w = 2,908

( 731 - w ) * w = 2908

731w - w^2 = 2908

w^2 - 731w + 2908 = 0

solving the quadratic equation gives

w = 727 or 4

since w is a one digit number then w = 4

plugging in w = 4 into xyz + w =731 we have

xyz + w =731

xyz + 4 =731

xyz =731 - 4

xyz  = 727

Hence the three digit number is 727 while the one digit number is 4

The multiplication of the expression ( √5 + √11 )( √5 - √11 ) is - 6.

Multiplication in elementary algebra is the process of figuring out the outcome of multiplying a number by a number b. The product of a and b is the outcome of multiplication, and each of the integers a and b is referred to as a factor of the product ab.

Consider the expression,

y = ( √5 + √11 )( √5 - √11 )

Using the distributive property,

a( b + c ) = ab + ac

y = (√5 + √11 )( √5 - √11 )

y = √5( √5 - √11 ) + √11( √5 - √11 )

y = ( √5 )² - √5 × √11 + √11 × √5 - ( √11 )²

y = 5 - √55 - √55 - 11

y = 5 - 11

y = - 6

The value of the expression (√5 + √11 )( √5 - √11 ) when simplified is - 6.

The required expression or inequality for possible widths of the rectangle is -4 < x < 3.

Given:

A rectangle has a length 6 meters more than six times the  width.

The area of the rectangle is less than 72 meters  squared.

We have to find,

The expression or inequality that represents all possible  widths of the rectangle.

Let x be the width of the rectangle.

Length of the rectangle is 6 meters more than six times the  width.

length = 6x + 6

Area of rectangle is:

Area = length × width

Area = (6x + 6) × x

Area = 6x² + 6x

The area of the rectangle is less than 72 meters  squared.

6x² + 6x < 72

6x² + 6x -72 < 0

Divide both sides by 6.

x² + x - 12 < 0

x² + 4x - 3x - 12 < 0

x(x + 4) - 3(x + 4) < 0

(x + 4) (x - 3) < 0

It is true if one factor is negative and other is positive. So,

x - 3 < 0 ⇒ x < 3  ...(i)

x + 4 > 0 ⇒ x > -4  ...(ii)

Using (i) and (ii), we get

-4 < x < 3

Therefore, the required expression or inequality for possible widths of the rectangle is -4 < x < 3.

4 loaves of white bread for every 5 loaves of wheat bread can be written as:

4M = 5N _____(1)

Total number of bread sold = 117

M + N = 117 _______(2)

The number of white bread sold:

From (1)

N = 4M / 5 Putting in (2)

Answer: (t-r) / 21 = -0.857    where,   t= -6 and r= 12

Step-by-step explanation:

Given data,

t-r divided by 21

where, t= -6 and r= 12

So, we can write,

                            = (t-r) / 21

Let us assume,

                  (t-r) / 21 = x

So,

           x = (t-r) / 21 { t = -6 and r = 12             (eq-1)

         x = (t-r) / 21

We can substitute,    t = -6 and r = 12   values in this equation 1

so, we can write,

                            x =   (t-r) / 21

                            x = (-6-12) / 21

                            x = -18/21

                            x = -6/7

                            x = -0.857

Therefore,

                       (t-r) / 21 = -0.857    where,   t= -6 and r= 12

9/29 < 1/a + 1/b < 7/12

Here we have two expression

3 < a < 4 and 4 < b < 5

We have to find the value of the expression

   1/a + 1/b

The lower bound of the expression is when we take the maximum value of both the expression  a and b

a = 4 and b = 5

 From this we get

= 1/ 4 + 1/5

= 5 + 4 / 20

9/ 20

In the same way, we get the higher bound of the expression taken by taking  the minimum value of both the expression a and b

a = 3 and b = 4

By putting the value of a and in the expression we get:

1/ 3 + 1/4

= 4+3 / 12

= 7/12

Thus we get the possible value of the expression :

9/20 <1/a + 1/b < 7/12
