Answer:

1135.38

Step-by-step explanation:

Original amount  = 1015;

First decrease = 6%

Followed by an increase  = 19%

Unknown:

Final amount:

Solution:

If 100% of a value implies multiplying by 1;

        6% decrease  = 0.94

        19% increase  = 1.19

Now;

Final amount  = 1015 x 0.94 x 1.19  = 1135.38

Answer:

selling price was 6750

Step-by-step explanation:

9000 x 0.25 = 2250

9000 - 2250 = 6750

Answer:

=rs. 6750

Step-by-step explanation:

marked price=     9000   =       100%

selling price=          ?        =       75%

loss=                        ?        =        25%

as he made a loss it means that he sold the sofa for a lower price hence the selling price will be lower than the marked price.

selling price = if  100% = 9000

        what about    75%?

   75% x 9000

        100%

=rs.6750            

Answer:

[tex] - 18 {x}^{4} + 117 {x}^{3} + 71 {x}^{2} - 52x - 28 [/tex]

ans

Answer:

The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].

(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.

Step-by-step explanation:

Let [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) =(0, y')[/tex], where [tex]P(x,y)[/tex] is a point that is equidistant from F and the y-axis. The following vectorial expression must be satisfied to get the location of that point:

[tex]F(x,y)-P(x,y) = P(x,y)-R(x,y)[/tex]

[tex]2\cdot P(x,y) = F(x,y)+R(x,y)[/tex]

[tex]P(x,y) = \frac{1}{2}\cdot F(x,y)+\frac{1}{2} \cdot R(x,y)[/tex] (1)

If we know that [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) = (0,y')[/tex], then the resulting vectorial equation is:

[tex]P(x,y) = \left(1,\frac{3}{2} \right)+\left(0, \frac{y'}{2}\right)[/tex]

[tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex]

The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].

If we know that [tex]y_{1}' = -3[/tex], [tex]y_{2}' = 0[/tex] and [tex]y_{3}' = 3[/tex], then the coordinates for three points that are equidistant from F and the y-axis:

[tex]P_{1}(x,y) = \left(1,\frac{3+y_{1}'}{2} \right)[/tex]

[tex]P_{1}(x,y) = (1,0)[/tex]

[tex]P_{2}(x,y) = \left(1,\frac{3+y_{2}'}{2} \right)[/tex]

[tex]P_{2}(x,y) = \left(1,\frac{3}{2} \right)[/tex]

[tex]P_{3}(x,y) = \left(1,\frac{3+y_{3}'}{2} \right)[/tex]

[tex]P_{3}(x,y) = \left(1,6 \right)[/tex]

(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.

The product of 12 and 2 minus the quotient of 45 and 5 is 84.

An expression is combination of variables, numbers and operators.

we need to find  the product of 12 and 2 minus the quotient of 45 and 5

the quotient of 45 and 5, we can calculate it by dividing forty five divided by 5.

45/5 is 9

2 minus the quotient of 45 and 5

So subtract 2 from 9

9-2=7

Now  the product of 12 and 2 minus the quotient of 45 and 5.

12 is multiplied with seven

12×7

84

Hence, the product of 12 and 2 minus the quotient of 45 and 5 is 84.

Answer:

34.5

Step-by-step explanation:

An easy way to find this out is plug in all the answers into our equation until we get 180. So here's what you do:

A) X=25.5

So put that in the equation replacing x like this :  2(25.5)-9 =42 then multiply by three which = 126, So, A) is not our answer, now do it with the rest until you get 180,

2(34.5)-9=60 60x3=180 so your answer will be the number you plug in aka:34.5

Answer:

Step-by-step explanation:

The beetle crawled 3 times more than the spider crawled.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that daniel watched a beetle and a spider on the sidewalk. the beetle crawled 1/2 of a yard and the spider crawled 1/6 of a yard.

The beetle crawled how many times is calculated as:-

Beetle crawled  = ( 1 / 2 ) ÷ (1 / 6) x Spider crawled

Beetle crawled = 3 x Spider crawled

Therefore, the beetle crawled 3 times more than the spider crawled.

Answer:

(2n + 1)(n + 3) + (2n + 1)(n - 2)

= (2n + 1)(n + 3 + n - 2)

= (2n + 1)2n + 1)

= 4n² + 4n + 1

= 2(2n² + 2n) + 1

can see 2(2n² + 2n) is   a multiple of 2 but 1 isnt  a multiple of 2

=>  2(2n² + 2n) + 1  is not a multiple of 2

=> (2n + 1)(n + 3) + (2n + 1)(n - 2) is not a multiple of 2
