maths angles- please help asap

Answers

Answer:

x = 20

Step-by-step explanation:

These angles are same-side supplementary, therefore they add up to 180°.

[tex]4x + 5x = 180 \\ 9x = 180 \\ x = 20[/tex]

Answer:

4x + 5x = 180

because of interior angle

hence, 9x = 180

x = 180/9

x = 20

one angle = 20*4 = 80

another angle = 20*5 = 100

3(2x+d)+c(x+5)=10x+17 find c and d

Answers

Answer:

c = 4, d = - 1

Step-by-step explanation:

Expand and simplify left side, then compare coefficients of like terms on the right side, that is

3(2x + d) + c(x + 5) ← distribute parenthesis

6x + 3d + cx + 5c

= x(6 + c) + 3d + 5c

Compare terms with those on the right side

coefficients of x- terms

6 + c = 10 ( subtract 6 from both sides )

c = 4

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

constant terms

3d + 5c = 17, that is

3d + 5(4) = 17

3d + 20 = 17 ( subtract 20 from both sides )

3d = - 3 ( divide both sides by 3 )

d = - 1

The value of c and d if 3(2x+d)+c(x+5)=10x+17  is 4 and -1 respectively

Given the equation:

3(2x+d)+c(x+5)=10x+17

Expand the bracket

6x + 3d + cx + 5c = 10x + 17

Collect the like terms

6x+cx + 3d + 5c = 10x + 17

x(6+c) + 3d + 5c = 10x + 17

Compare the coefficients of x on both sides

x(6+c) = 10x

6+c = 10

c = 10 - 6

c = 4

Similarly:

3d + 5c = 17

3d + 5(4) = 17

3d + 20 = 17

3d = 17 - 20

3d = -3

d =-3/3

d = -1

Hence the value of c and d if 3(2x+d)+c(x+5)=10x+17  is 4 and -1 respectively

Volume

= 1/3 * π* r² * h

= 1/3 * 3.14 * 5² * 5

= 1/3 * 3.14 * 25 * 5

= 130.83 units ³

Hope it will help :)❤

Answer:

V = 130.83

Step-by-step explanation:

The equation for the volume of a cone is:

[tex]V =\frac{ \pi r^2h}{3}[/tex]

we can see that r = 5, and h = 5

we will use 3.14 for the value of pi

so, we just fill in the equation with the values we know and solve :)

[tex]V=\frac{\pi r^2h}{3} \\V=\frac{(3.14) (5)^2(5)}{3}\\V=\frac{(3.14) (25)(5)}{3} \\V=\frac{392.5}{3} \\V= 130.8333 (approx.)[/tex]

the question wants the nearest hundred, so the final answer is

V = 130.83

Answers

Answer:

( x, y ) = ( 4, 1/3)

Step-by-step explanation:

x - 3y = 3

2x +9y = 11

1. substitute the value of x

   x= 3 + 3y

   2x + 9y = 11

2. solve equation

   2 (3 + 3y) +9y = 11

3. substitute the value of y

  y = 1/3

4. solve equation

  x = 3 + 3 x 1/3

   x = 4

5. check solution

 (x, y)  = ( 4, 1/3 )

 check  x ---->  4 - 3 x 1/3 = 3

  check y ------> 2 x 4 + 9 x 1/3 = 11

    for x----> 3=3

     for y----> 11=11

   

A bicycle factory produces 1505 bicycles in a week . How many bicycles will it produce in 30 days

Answers

Answer:

6450

Step-by-step explanation:

Because 1505 ÷ 7 = 215

The bicycle factory produces 215 bikes in 1 day.

So: 215 • 30 = 6450

Hope this helps!

The answer would be 6450 because 1505/7(days in a week)=215 so 215*30=6450

Hope this helps
