) Find the area of a circle with radius, r = 53cm.
Give your answer rounded to 3 SF.

Answers

Answer 1

Area of a circle = pi r^2
= 3.14 x 53^2
= 3.14 x 2809
Area of circle = 8820.26 cm^2

Therefore area of circle to 3 significant figures is 8820 cm^2

[2] 4v = -32
// Solve equation [2] for the variable v

$4, 230
$4, 302
$4, 203

Answers

Answer:

$4,230

Step-by-step explanation:

There are 846 puzzles sold and including tax, it is $5 per puzzle. Multiply the amount of puzzles by cost and you get the total cost of all puzzles sold including tax.

$4,230 if you multiply 846x5 you will get $4,230 which is the total cost of the puzzle

2. Solve the system of equations using the substitution method.
y = 10 - 4x

2x + 3y = 20
Please show how you got it

Answers

Answer:

x = 1

Step-by-step explanation:

2x + 3y = 20

2x + 3(10-4x) = 20

2x + 30 - 12x = 20

combine like terms

-10x + 30 = 20

-30 -30

-10x = -10

divide both sides by -10

x = 1

The solution of the linear equations y = 10 - 4x and 2x + 3y = 20 will be (1, 6).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equations are given below.

y = 10 - 4x ...1

2x + 3y = 20 ...2

Substitute equation 1 in equation 2, then we have

2x + 3(10 - 4x) = 20

2x + 30 - 12x = 20

10x = 10

x = 1

Then the value of the variable 'y' will be given as,

y = 10 - 4(1)

y = 10 - 4

y = 6

The solution of the linear equations y = 10 - 4x and 2x + 3y = 20 will be (1, 6).

What is the solution to the equation 36 – 5x = 5 – 6(x - 4) ?

68bpoints

Answers

Step-by-step explanation:

36-5x=5-6(x-4)

36-5x=5-6x+24

-5x+6x=24+5-36

x=29-36

x=-7

Answer:

x = -7

Explanation:

36 − 5x = 5 − 6(x − 4)

[ Simplify both sides of the equation ]

36 − 5x = 5 − 6(x − 4)

36 + −5x = 5 + (−6)(x) + (−6)(−4) [ Distribute ]

36 + −5x = 5 + −6x + 24

−5x + 36 = (−6x) + (5 + 24) [ Combine Like Terms ]

−5x + 36 = −6x + 29

[ Step 2: Add 6x to both sides ]

−5x + 36 + 6x = −6x + 29 + 6x

x + 36 = 29

[ Step 3: Subtract 36 from both sides ]

x + 36 − 36 = 29 − 36

x = −7

Can you find the slope-intercept equation of each line and type the correct code? Please remember to type in ALL CAPS with no spaces.

Answers

Answer:

The answer for the code is CGIA

Step-by-step explanation:

The slope- intercept of each line is

First line,

y= x+ 2

Second line,

y = 2x +2

Third line,

y= -x +1

Fourth line,

y= -2x - 2

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

First line,

slope intercept form

(y - 3)= 1(x-1)

y= x+ 2

Second line,

slope intercept form

(y - 2)= 2(x-0)

y = 2x +2

Third line,

slope intercept form

(y + 2)= (-1)(x - 3)

y= -x +1

Fourth line,

slope intercept form

(y + 2 )= -2(x-0)

y= -2x - 2

If the value of the function g(x) is 4. Then the value of the variable 'x' is 3.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The function is given below.

g(x) = 3x - 5

The degree of the function is one. Then the function is a linear function.

If the value of the function g(x) is 4. Then the value of the variable 'x' is calculated as,

g(x) = 3x - 5

4 = 3x - 5

4 + 5 = 3x

9 = 3x

3x = 9

x = 9 / 3

x = 3
