Find the circumference and area of each circle. Include the formula thank you

Answer:

$4871.25

Step-by-step explanation:

You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:

0.88x = 4286.70

You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:

x = 4871.25

Answer:

A straight line is 180° , so if you subtract 60 from 180 you get 120, and you divide 120 by 6 so the answer is 20

Answer:

x= 20

Step-by-step explanation:

Both angles form a linear pair = 180 o

6x+60 = 180

6x = 120

x = 20

6x20 +60 = 180

120 +60 = 180

Answer:

x < 3

Step-by-step explanation:

-3 - 6(4x+6) > - 111

-3 - 24x - 36 > -111

-24x - 39 > -111

-24x > -72

dividing by a negative flips the sign

x < 3

Step-by-step explanation:

80 - 30.74 = 49.26

49.26 divided by 8.21 =6

Answer:

A and B are functions

Step-by-step explanation:

for A, none of the x's repeat which makes it a FUNCTION

for B, when it starts with x^2, it will always be a FUNCTION (its a quadratic)

for C, 10 repeats for the x so it is NOT A FUNCTION

Answer:

it would be four games because take away the 4 dollars and then add 5x4 together

Answer:

A & C

Step-by-step explanation:

for A - and + is always -

so 2.3-2.3 =0

for C - and - is always + so

-2.6--124 = -2.6+124

=121.4 which is positive

Answer:5,4

Step-by-step explanation:

Answer:

I think the answer is 4,5.

Step-by-step explanation:

in a coordinate grid your suppose to start X axis then the y axis so if you go 6 units left and going 4 units down then I think your answer might be 4,5. i really hope this helps out and this is right!-

=======================================================

Explanation:

a1 = first term

a2 = second term

a3 = third term

and so on, until we reach a37 to represent the 37th term

We don't know the first term, but we'll call it x for now. We'll also let d be the difference between each adjacent term, aka the common difference.

Meaning that,

and so on, until,

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

Add up the first three terms (a1 through a3) and set the sum equal to 12

Then do a bit of algebra to get

a1+a2+a3 = 12

(x)+(x+d)+(x+2d) = 12

3x+3d = 12

3(x+d) = 12

x+d = 12/3

x+d = 4

x = 4-d

Do the same for the last three terms, but the sum here is 318

a35+a36+a37 = 318

(x+34d)+(x+35d)+(x+36d) = 318

3x+105d = 318

3(x) + 105d = 318

3(4-d)+105d = 318 .... replace x with 4-d; isolate d

12-3d+105d = 318

102d+12 = 318

102d = 318-12

102d = 306

d = 306/102

d = 3

The common difference is 3. It means each term is increasing by 3.

Use this value of d to find x

x = 4-d

x = 4-3

x = 1

The first term is 1. That makes the second term x+d = 1+3 = 4, then the third term is x+2d = 1+2*3 = 7, and so on.

The sum of the first three terms is 1+4+7 = 12. That helps partly confirm the answer.

Also we have,

Or you could note that the 35th term is 103, and then you increase by 3 each time to get the remaining two terms.

The last part of the confirmation is adding up those three last terms: 103+106+109 = 318, so the answer is fully verified at this point.

Side note: An arithmetic sequence never ends. There technically is no "last term"; however, since we're confined to focusing on these specific 37 terms, we can get away with using the phrasing.

Answer:

diameter=14

radius =14/2=7

area =πr²

hope it helps

Step-by-step explanation:

Area of circle = 2π r²

diameter is 14 cm so radius will be 7 cm

= 2 × 22/7 × 7 × 7

= 44 × 7

= 308 cm²

Responder:

A - B = {1, 4, 5}

Explicação passo a passo:

Conjunto A - Conjunto B; Isso significa que queremos um conjunto que contém apenas elementos que estão no conjunto A, portanto, os elementos do conjunto A que também estão presentes no conjunto B estão isentos.

A = {1, 2, 3, 4, 5}

B = {2, 3, 7}

A - B = {1, 4, 5}

Portanto, apenas] 1, 4, 5} são elementos do conjunto A e não do conjunto B

Answer:

x = 3 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

there's no x in the equation you wrote.

Did you mean?

2x + 8 = 15

Subtract 8 from both sides

2x = 7

Divide both sides by 2

x = 7/2

x = 3 [tex]\frac{1}{2}[/tex]

Answer:

x = 1

Step-by-step explanation:

4x + 8 = 12x

4 (1) + 8 = 12 (1)

4 + 8 = 12

12 = 12

your answer is x = 1

Answer:

4x+8=12x

8=8x subtract 4 on both sides

1=x divide by 8 on both sides

Answer:

Perimeter of ΔABC = 16.46 units

Step-by-step explanation:

By applying cosine rule (CAH) in the given triangle ADB,

cos(∠BAC) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(55°) = [tex]\frac{3}{AB}[/tex]

AB = 5.23 units

Since, ΔABC is an isosceles triangle

AB = BC = 5.23 units

AD = DC = 3 units [Perpendicular drawn from a vertex of an isosceles triangle is a perpendicular bisector of the opposite side]

Therefore, AC = AD + DC = 6 units

Now perimeter of ΔABC = AB + BC + AC

                                          = 5.23 + 5.23 + 6

                                          = 16.46 units
