Answer:

120000

Step-by-step explanation:

5 x 20 = 100%

6000 x 20 = 120,000

Answer:

Adults= 110

Children= 340

Step-by-step explanation:

Given data

let adults be x

and children be y

x+y= 450----------1

2x+y=680---------2

from 1

x= 450-y

put this in 2

2(450-y)=680

900-2y=680

900-680=2y

220=2y

y= 220/2

y= 110

x+110= 450

x= 450-110

x=340

Option A is ur answer

as

5^2 + 12^2 = 25 + 144

= 13^2

Answer:

5, 12, 13

Step-by-step explanation:

because

5²+12²=169

root 169= 13

basically it's this because the numbers are still whole

Answer:

1/2 kg

Step-by-step explanation:

m = 0.5 or 1/2

Answer:

−36.89

31.22

Step-by-step explanation:

Answer:

p = 2

Step-by-step explanation:

Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.

Therefore, plug x = 2p - 1 & y = p in the above equation.

9p + 12 = 10(2p - 1)

9p + 12 = 20p - 10

12 + 10 = 20p - 9p

22 = 11p

p = 22/11

p = 2

Step-by-step explanation:

Answer:

x (11 unit) is the longest side

Step-by-step explanation:

Given:

Sides;

7, x, and x−1

Perimeter = 28

Find:

Longest side

Computation:

Perimeter = sum of all sides

So,

7 + x + (x -1) = 28

2x + 6 = 28

x = 11

So,

x -1 = 11 - 1 = 10 unit

x (11 unit) is the longest side

Answer:

7.) x = 21

8.) y = 6

9.) angle F = 62 degrees

10.) TS = 10

Step-by-step explanation:

5y-2 = 28

5y = 30

y = 6

4x+6 = 90

4x = 84

x = 21

angle F = 90-28

angle F = 62 degrees

3z-8 = z+4

2z = 12

z = 6

TS = z+4 = 10

Answer:

4ab

Step-by-step explanation:

(a+b)^2-(a-b)^2

=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)

=a^2 + 2ab + b^2 - a^2 + 2ab - b^2

=2ab + 2ab

=4ab

Step-by-step explanation:

1st=8+4=12

2nd the answer is to the nearest 7.06

3rd =2+2³.7=2+13=15

4th=(36÷(4+5))+25=36÷9+25=4+25=29

5th=16÷16+8-3=1+8-3=9-3=6

6th=8-2.4=5.6

Answer:

(0,7)

Step-by-step explanation:

This equation is already in slope-intercept form, (y=mx+b), where m is the slope, and b is the y-intercept.

From the equation, we see that (0,7) is the y-intercept.

Answer:

James = 119 points

Sarah = 357 points

Roberts = 51 points

Step-by-step explanation:

Given that :

James = x points

Sarah = 3x points

Roberts = x - 68 points

Each point = 3 pence

All students have a total of £15.81

1 pound = 100 pence

£15.81 pound = 1581 pence

3x + 3(3x) + 3(x - 68) = 1581

3x + 9x + 3x - 204 = 1581

15x - 204 = 1581

15x = 1581 + 204

15x = 1785

x = 1785 / 15

x = 119

Hence,

James = 119 points

Sarah = 119 * 3 = 357 points

Roberts = 119 - 68 = 51 points

Answer:

The value of a = 4 , b = 3

Step-by-step explanation:

Given the equation,

x⁴ - 4[tex]x^{b}[/tex] + 6x² - ax + 1

so, the coefficients are -      1     4      6     a     1

the Pascal's triangle is as follows :

                                         1

                              1                     2

                   1                   2                        1

         1                   3                   3                         1

 1                4                   6                      4                       1

So,

from Pascal's triangle ,

we can see that , after comparing with given equation , we get

Row n = 4

The coefficient be 1 4 6 4 1

∴ we get

a = 4

and

(x+y)⁴ = x⁴ + 4x³y + 6x²y² + 4xy³ + y⁴

Now, as given equation be x⁴ - 4[tex]x^{b}[/tex] + 6x² - ax + 1

By comparing we get y = -1 and b = 3

So, we get

a = 4 , b = 3

Answer:

e. 9 ft

Step-by-step explanation:

Answer: No solutions

Step-by-step explanation:

You can either use substitution or elimination

You can plug in y to the first equation to get x-(x-4)=6 to get 4=6 which is not possible so no solutions
