When John was six years old he hammered a nail into his favourite tree to mark his height. Ten years later at age sixteen, John returned to see how much higher the nail was. If the tree grew by five centimetres each year, how much higher would the nail be?

Answer:

12 and 14

Step-by-step explanation:

Let x represents an even integer. Another positive consecutive even integer will be (x+2).

According to question,

The difference of the squares of two positive consecutive even integers is 52 i.e.

[tex](x+2)^2-x^2=52\\\\x^2+4+4x-x^2=52\\\\4+4x=52\\\\4x=52-4\\\\4x=48\\\\x=12[/tex]

First integer = 12

Another integer = 12+2 = 14

Complete Question:

The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the  cost, C.

Answer:

[tex]C = 0.45n[/tex]

Step-by-step explanation:

Given

[tex]5\ peppers = \$2.25[/tex]

Required

Determine the relationship between C and n

[tex]5\ peppers = \$2.25[/tex]

Divide both sides by 5, to get the cost of 1 pepper

[tex]\frac{5\ peppers}{5} = \frac{\$2.25}{5}[/tex]

[tex]1\ pepper = \frac{\$2.25}{5}[/tex]

[tex]1\ pepper = \$0.45[/tex]

Multiply both sides by n to get the cost of n pepper

[tex]n*1\ pepper = \$0.45*n[/tex]

[tex]n\ pepper = \$0.45n[/tex]

So, we have:

[tex]C = 0.45n[/tex]

Answer:

3/16 of her garden are red roses

she was not correct, 2/4 is not equal to 3/16

Step-by-step explanation:

3/4 garden are roses

1/4 of those are red  (1/4 of 3/4)

3/4 (1/4) = 3/16 of her garden are red roses

Answer:

Yes she is correct because if you have the 3/4 u still have 1/4 un planted an then she adds the 1/4 an that would make it 2/4.

Answer:

Perimeter is equal to all four sides added together.

Length = 3W; L=3W

So

P = 2(W) + 2(L)  substitute the equation for length above you get

P = 2(W) + 2(3W)  and combine

P = 2W + 6W = 8W; put in what the perimeter is and solve for W

66 = 8W, so W = 8.25

W = 8.25, L = 24.75

Answer:

The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]

Step-by-step explanation:

Diagonal of a square:

The diagonal of a square is found applying the Pythagorean Theorem.

The diagonal of the square is the hypothenuse, while we have two sides.

Diagonal of 12m:

This means that [tex]d = 12[/tex], side s. So

[tex]s^2 + s^2 = 12^2[/tex]

[tex]2s^2 = 144[/tex]

[tex]s^2 = \frac{144}{2}[/tex]

[tex]s^2 = 72[/tex]

[tex]s = \sqrt{72}[/tex]

Factoring 72:

Factoring 72 into prime factors, we have that:

72|2

36|2

18|2

9|3

3|3

1

So

[tex]72 = 2^{3}*3^{2}[/tex]

So, in simplest radical form:

[tex]s = \sqrt{72} = \sqrt{2^{3}*3^{2}} = \sqrt{2^3}*\sqrt{3^2} = 2\sqrt{2}*3 = 6\sqrt{2}[/tex]

Perimeter of the garden:

The perimeter of a square with side of s units is given by:

[tex]P = 4s[/tex]

In this question, since [tex]s = 6\sqrt{2}[/tex]

[tex]P = 4s = 4*6\sqrt{2} = 24\sqrt{2}[/tex]

The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]

Step-by-step explanation:

Answer:

x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 = 9x+18

so there are 9 twos or 18 and 9x. No value is provided for x so the answer is 18+9x.

Answer:

f(3) =-1

Step-by-step explanation:

f(x) = x^2 - 5x + 5

Let x=3

f(3) = 3^2 -5(3) +5

      = 9 -15+5

      = -6+5

      =-1

Answer:

Step-by-step explanation:

x-5(x-1) = x- (2x-3)​

x  + x *(-5) + (-1) * (-5) = x +  2x*(-1) + (-3)*(-1) {use distributive property}

x - 5x + 5 = x - 2x +3   {Combine like terms}

    -4x + 5 = - x +3           {Add 'x' to both sides}

-4x + 5 + x  = -x + x + 3

       -3x + 5 = 3           {subtract 5 from both sides}

            -3x = 3 - 5

            -3x = -2           {Divide both sides by (-3)}

              x = -2/-3

               x = 2/3

Answer:

2) x = -3

Step-by-step explanation:

Collect like terms, so gather all your x's on one side, and numbers in the other.  Add -6x and +15 to both sides, so you get -2x - 6x = +9 + 15, so we have -8x = 24, divide both sides by -8 you get x = -3.

Answer:

900

Step-by-step explanation:

The area of the final triangle would be 900 cm².

Scale factor is used to compare the final and initial dimensions of the figure. Mathematically, we can write scale factor -

{K} = {final dimensions/initial dimensions}

Given is that a triangle has an area of 36 cm². The base and height are scaled by a factor of 5.

Assume the initial dimensions of the triangle be {x} and {y} respectively. So, we can write the initial area as -

{1/2}{x}{y} = 36

{x}{y} = 72

After the scaling, we can write the final area as -

A = {1/2}{5x}{5y}

A = {25/2}{x}{y}

A = 12.5 x 72

A = 900 cm²

Therefore, the area of the final triangle would be 900 cm².
