The circumference is 16 pi what is the area

Answer:

yeah it easy

Step-by-step explanation:

Answer:

5, 9

Step-by-step explanation:

let

x= first number

y = second number

x- y= 4( equation 1)

xy=45( equation 2)

From equation 1

x= 4+y( equation 3)

put equation 3 into equation 2

( 4+y)y=45

4y+y^2=45

( y-5)(y+9)=0

y=5,-9

Then put y=5 into equation 3

x=9

Answer:

-9 and 5

Step-by-step explanation:

Let's call the first number N1 and the second number N2.

So, let's call N1 the smaller number and N1=x

Let's call N2 the larger number and N2=x+4.

 X(X+4)=45

x^2+4x=45

x^2+4x-45=0

(x+9)(x-5)=0

X=-9, X=5

Answer:

Width = 46 yards, Length=175 yards.

Step-by-step explanation:

Perimeter of rectangle = 2(length) +2(width)

We know that the length is 4width-9, so we can substitute that in for the length.

442= 2(4w-9)+2w, Next distribute

442=8w-18+2w, Now add like terms

442=10w-18, Move 18 to the other side

460=10w, solve for w

width= 46 yards.

Now we have 442=2(length)+2(46), subtract 92 to the left

350=2(length), divide by 2

Length= 175 yards.

Check your work with P=2(175)+w(46)

P=442 yards.

Answer:

x = 1 is not a solution to the equation

Step-by-step explanation:

2x + 4 = -3x - 2            x = 1

2(1) + 4 = -3(1) - 2

2 + 4 = -3 - 2

6 = -5 FALSE

Answer:

Total no of bracelets = 5s+28

Step-by-step explanation:

Let Sarah made s bracelets.

Maria made 7 more than Sarah i.e. 7+s

Julie made 3 times as many as Maria i.e. 3(7+s)

Total no of bracelets made is equal to the sum of the bracelets made by Sarah, Maria and Julie.

Total = s+ 7 + s + 3(7+s)

= 2s+7+21+3s

=2s+3s+21+7

= 5s+28

So, there are (5s+28) bracelets.

Answer:

75, 77

Step-by-step explanation:

Let the first odd number = 2x -1

Let the second odd number = 2x + 1

2x - 1 + 2x + 1 + 18 = 170           Combine like terms on the left.

4x + 18 = 170                             Subtract 18 from both sides.

4x = 170 - 18                             Combine like terms on the right

4x = 152                                     Divide by 4

4x/4 = 152/4

x = 38

2 * 38 - 1 = 75

2 * 38 + 1 = 77

649 divided by 2 is equal to 347

Answer:

-15

Step-by-step explanation:

10 x -15 = -150

-150 + 50 = -100

5 x -15 = -75

-75 - 25 = -100

Step-by-step explanation:

brainliest me

Answer:

15 or 16. 54 is not listed.

Step-by-step explanation:

pretend that 11 is 0. that means 54 is 43.

then you do 43 divided by 3 or 43/3  

but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.

Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.

Answer:

see explanation

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = a₂ - a₁ = 14 - 11 = 3, then

[tex]a_{n}[/tex] = 11 + 3(n - 1) = 11 + 3n - 3 = 3n + 8

Thus

a₅₄ = 3(54) + 8 = 162 + 8 = 170

The Answer should be C.) Y=x-20

Answer:

9.6 ft

Step-by-step explanation:

Sin=opposite/hypotenuse

The required height of the ladder is 9.6 feet.

Given that,
The sliding board is 15 feet long and meets the ground at a 40-degree angle.The height of the ladder is to be determined.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.



Here,
Let the height of the ladder be p
Now, applying trigonometric operations,
sin 40 = p / 15
p = 15 sin40
p = 0.64 * 15
p = 9.6

Thus, the required height of the ladder is 9.6 feet.

Answer:

= x^2 ( 2x^3- 3x^2 - 8x + 12)

Step-by-step explanation:

(x^3-4x) (2x^2-3x)

= x^3(2x^2-3x) -4x(2x^2-3x)

= 2x^5-3x^4-8x^3+12x^2

= x^2 ( 2x^3- 3x^2 - 8x + 12)
