Mathematics

LiRa [457]2 years ago

Answer:

length = 30 cm

Breadth = 10 cm

Step-by-step explanation:

Length = x cm

Breadth = (1/3)x

Perimeter = 80 cm

2(length + breadth) = 80

2* (x + (1/3)x) = 80

2*(\frac{3}{3}x+\frac{1}{3}x) = 80\\\\2*(\frac{4}{3}x) = 80\\\\\frac{8}{3}x = 80\\\\x = 80*\frac{3}{8}\\\\x = 10*3

x = 30cm

length = 30 cm

breadth = \frac{1}{3}*30=10 cm

Write the equation 2x-3y=6in slope -intercept form​
Tcecarenko [31]

Answer:

y = 2/3 x -2

Step-by-step explanation:

Slope intercept form is y = mx+b where m is the slope and b is the y intercept

We need to solve for y

2x-3y = 6

Subtract 2x from each side

2x-2x-3y=-2x+6

-3y = -2x+6

Divide  by -3

-3y/-3 = -2/-3x+6 /-3

y = 2/3 x -2

The slope is 2/3 and the y intercept is -2

˚

. Thus, if

∠

1

and

∠

2

are complementary,

m

∠

Ace autos sell cars and pay sue each month as follows
Dima020 [189]

Sue's total pay of year will have three parts

1) Fixed Salary for 12 months

  one month salary = £1410

  so 12 month salary = £1410 x 12 = £16920

2) 26% of total profit

   Total cost to the company- £473,500

   Total income for the company - £549,000

   Profit =  Total income for the company - Total cost to the company

             =  £549,000 - £473,500 = £75500

    Sues income from profit = 26% of £75500 = (26 × 75500)/100 = £19630

3) Bonus if Sue sells at least 16 cars

   Given number of months when sue solds atleast 16 cars = 4

   So bonus income = 4 × 390 = £1560

Adding the three above parts

Sue's total pay for the year = £16920 + £19630 + £1560 = £38110
