Find the circumference of the circle.

Answer:

[tex]y = -3+ rx[/tex]

Step-by-step explanation:

Given

[tex]Base = -3C[/tex]

[tex]Time = x[/tex]

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

[tex]y = Base + Rate * Time[/tex]

[tex]y = -3+ r* x[/tex]

[tex]y = -3+ rx[/tex]

Step-by-step explanation:

Answer: 6.4

Step-by-step explanation:

d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)

d = sqrt (41)

d = 6.4

Answer:

D  (x,5y)

Step-by-step explanation:

Answer:

x > 2

Step-by-step explanation:

Since the dot is not filled in, it does not include 2. Since it is moving to the right, it means it is more than 2.

Hope that helps!

Answer:

x>2

Step-by-step explanation:

since the circle on the number two is a hollowed-out circle then it is less than greater than so it is not equal to anything. and since the arrow is pointed greater than 2.

So all values of x are greater than 2

Hope this helps :)

Answer:

two times the sum of a number and 5

Step-by-step explanation:

Answer:

Total students = 460+320+165=945

Key stage 3 ... asafraction = 460 divide by 945

the number in a sample of 100 = 460 divide by 945 x 100= 48.67

So 48 or 49 (are both, acceptable answers).

Answer:

3

Step-by-step explanation:

The answer is Option One

Answer: A. f(n) = 4 ∙ 2n-1

Step-by-step explanation:

because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.

Answer:

TV Price: 776.25

DVD Player Price: 258.75

Step-by-step explanation:

Television:

1,035 -  258.75 = 776.25

DVD Player:

1,035/2 = 517.5

517.5/2 = 258.75

The answer is 35.1 cm².

Hope this helps; have a great day!

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (√3/4)s²

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

Answer:

x = -2

Step-by-step explanation:

Answer:

x= -2

Step-by-step explanation:

(2x-1)= 5(x+1)

2x - 1 = 5x + 5

-2x -2x

- 1 = 3x + 5

-5 -5

-6 = 3x

-6/3= 3x/3

Answer: 45$

Step-by-step explanation:

Given

Principal [tex]P=\$500[/tex]

Rate [tex]R=6\%[/tex]

time [tex]t=18\ \text{months or}\ 1.5\ \text{years}[/tex]

Simple interest is given by

[tex]\Rightarrow S.I.=\dfrac{P\times R\times T}{100}[/tex]

In the question, time is taken in months which is incorrect

Putting values

[tex]\Rightarrow S.I.=\dfrac{500\times 6\times 1.5}{100}=45\$[/tex]

Answer:

I think the area is 38

Step-by-step explanation:

area =38

Step-by-step explanation:

eqn of line : y = mx+ c

m = slope or gradient

c = y-intercept.

Lets take (1,6) = (x1,y1) and (2,3) = (x2,y2)

[tex]m \: = \frac{y1 - y2}{x1 - x2} \\ = \frac{6 - 3}{1 - 2} \\ = \frac{3}{ - 1} \\ = - 3[/tex]

Substitute x = 1 and y = 6 into equation,

[tex]6 = ( - 3)(1) + c \\ 6 = - 3 + c \\ c = 6 + 3 \\ = 9[/tex]

Therefore substituting m and c value, equation of line is

[tex]y = - 3x + 9[/tex]

Answer:

The missing value = [tex]23\frac{1}{24}[/tex]

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

              the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + [tex]59\frac{5}{8}[/tex] = [tex]82\frac{2}{3}[/tex]

⇒x = [tex]82\frac{2}{3}[/tex] - [tex]59\frac{5}{8}[/tex]

     = [tex]\frac{248}{3} - \frac{477}{8}[/tex]

     = [tex]\frac{1984 - 1431}{24}[/tex]

     = [tex]\frac{553}{24}[/tex]

     = [tex]23\frac{1}{24}[/tex]

⇒x = [tex]23\frac{1}{24}[/tex]

∴ we get

The missing value = [tex]23\frac{1}{24}[/tex]

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.

Answer:

n - 21

Step-by-step explanation:

"difference" implies subtraction here.  

The difference between a number and 21 is n - 21.

Answer:

420 x .1 = 42

420 + 42 = 462

400 x .2 = 80

400 + 80 = 480

The first one is cheaper

144. Use the formula for the volume of a cone, since the answer is in terms of pi disregard the pi in the formula and solve using (r^2)(h/3) which will give you the answer in terms of pi.

Answer:

$67.2

Step-by-step explanation:

8% of $52.50

52.5 × 8/100 = $4.2

20% of $52.50

52.5 × 20/100 = $10.5

total

$52.5 + $4.2 + $10.5 =$67.2
