Add 2 it becomes 654

654 / = 218

Answer:

I believe the smallest you can add is two, because 654 / 3 is 218.

Step-by-step explanation:

652 / 3 = 217.333333333

653 / 3 = 217.666666667

654 / 3 = 218

Answer:

86

Step-by-step explanation:

the rectangle portion is 18*4= 72

1 triangle portion is 1/2bh where the base is 4 and height is 3.5

1/2*14=7

the 2nd triangle as the same proportions, so it is also 7

72+7+7=86

Answer:

P u s s y + p e n I s = babyyyyyyyyyy

Answer:

129 cm

Step-by-step explanation:

The total height of all the people: 150 × 4 = 600 cm

The total height of Sally, Jackson and Tina: 145 × 3 = 435 cm

David’s height: 600 – 435 = 165 cm

Tina’s height: 165 + 5 = 170 cm

Jackson’s height: 170 × 4/5 = 136 cm

Therefore, Sally’s height: 600 – 165 – 170 – 136 = 129 cm

Thenks and mark me brainliest :))

The height of Sally will be 133 centimeters and the height of Jackson is 132cm.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The average height of Sally, Jackson, Tina, and David is 150 cm per person. Then the equation is given as,

(S + J + T + D) / 4 = 150

S + J + T + D = 600  ...1

The average height of Sally, Jackson, and Tina is 145 cm per person. Then the equation will be

(S + J + T) / 3 = 145

S + J + T = 435      ...2

Tina is 5 cm taller than David. Then the equation will be

T = D + 5  ...3

Jackson is 4/5 as tall as David. Then the equation will be

J = (4/5)D    ...4

From equations, 1 and 2, then we have

435 + D = 600

D = 165 cm

From equation 4, then we have

J = (4/5) x 165

J = 132 cm

From equation 3, then we have

T = 165 + 5

T = 170 cm

From equation 2, then we have

S + 132 + 170 = 435

S = 133 cm

The height of Sally will be 133 centimeters.

Answer:

227.5 grams

Step-by-step explanation:

We know that a single 10p coin weights 6.5 g

Now we want to find the weight of a bag of 10p coins, such that the net value is £3.50  (where the weight of the bag is neglected)

The value of a 10p coin is £0.10

So the first thing we need to find, is how many coins there are in the bag.

To find that, we need to find the quotient between the total value and the value of a single coin:

£3.50/£0.10 = 35

So in the bag, we have 35 coins, and each one of them weighs 6.5 grams

Then the total weight is 35 times 6.5 grams:

35*6.5 g= 227.5 grams

Answer:

[tex] (A)\displaystyle \begin{array} {ccc} \displaystyle y = - 2 \\ x - 2y = 6\\ \end{array} [/tex]

Step-by-step explanation:

since the line is horizontal and passes -2 the equation of the blue line should be

[tex] \displaystyle \large y = - 2[/tex]

remember The form of equation of a line

[tex] \displaystyle \boxed{ \displaystyle y = mx + b}[/tex]

where m is slope of the line and b is the y-intercept we can clearly see that the red line crosses y-axis at (0,-3) therefore b=-3

to figure out m we can consider the following formula:

[tex] \displaystyle m = \frac{ \Delta y}{ \Delta x} [/tex]

from the graph we acquire ∆y=1 and ∆x=2

thus substitute:

[tex] \displaystyle m = \frac{ 1}{ 2} [/tex]

so we have figured out m and b

therefore our equation of blue line is

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

our given options are in standard form so

move -3 to left hand side and change its sign:

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

cross multiplication:

[tex] \displaystyle 2y + 6= x[/tex]

move 6 to right hand side and x to left hand side and change its sign

[tex] \displaystyle - x + 2y = - 6[/tex]

multiply both sides by -1:

[tex] \displaystyle x - 2y = 6[/tex]

hence, our system of linear equation is

[tex] \displaystyle \begin{cases} \displaystyle y = - 2 \\ x - 2y = 6\\ \end{cases}[/tex]

If its fractions, you would do 5/47

Answer: x = -30

Step-by-step explanation:

y = -20 by using process of elimination substitute y as -20 in either of the equations you get -30 for x

The solution to the system of equations is x = 390 and y = 50. The value of x is equal to 390.

To find the value of x, solve the system of equations using the method of  substitution . Let's use the method of elimination:

Given equations:

x - 12y = -210                      (1)

x - 6y = 90                          (2)

To eliminate x, we can subtract equation 2 from equation 1:

(x - 12y) - (x - 6y) = (-210) - 90

Simplifying the equation:

x - 12y - x + 6y = -210 - 90

-6y = -300

Divide both sides of the equation by -6:

y = -300 / -6

y = 50

Now, substitute the value of y back into either equation:

x - 6(50) = 90

Simplify the equation:

x - 300 = 90

Add 300 to both sides of the equation:

x = 90 + 300

x = 390

Therefore, the solution to the system of equations is x = 390 and y = 50.

Given:

Dividend = [tex]2x^2+5x-3[/tex]

Divisor = [tex]x+3[/tex]

To find:

The remainder by using the synthetic division.

Solution:

We have,

Dividend = [tex]2x^2+5x-3[/tex]

The coefficients of dividend are 2, 5, -3. Write these elements in the top row of synthetic division.

Divisor = [tex]x+3[/tex]

The value of divisor is 0 at [tex]x=-3[/tex]. So, write -3 on the left side of division.

Write down the first coefficient of dividend in bottom row, then multiply it by -3 and write the result below the next coefficient of dividend then add the coefficient and write the result in bottom row, then repeat the steps up-to last coefficient.

-3    |        2          5         -3

      |                    -6         3

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

               2         -1           0

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

Here, the first two elements of the bottom row represent the coefficient of quotient and last element represent the remainder.

Therefore, the remainder is 0.

  11. axis of symmetry: x=4; vertex: (4, 4); domain: all real numbers; range: y ≤ 4

  12. x = -4, -2

Step-by-step explanation:

10. Your graph is substantially correct. (You might do yourself a favor by adding points ±1 either side of the vertex. This will help to make the graph more rounded near the bottom.) The red graph in the attachment is the graph of this function.

__

11. The vertex form of this equation is ...

  f(x) = -(x² -8x) -12 = -(x² -8x +16) -12 +16

  f(x) = -(x -4)² +4

This tells you the vertex is (4, 4). The axis of symmetry is the vertical line through the vertex, so is x=4. The domain of all polynomial functions is "all real numbers." This has a maximum at y=4, so the range is y ≤ 4.

__

12. The vertex form of this equation is ...

  f(x) = (x +3)² -1

so the vertex is (-3, -1). Points at x = -3 ± 1 will be the x-intercepts, so the solutions to the equation f(x) = 0. The graph of it is the green graph in the attachment.

13c. [tex]( x +3 )^2 + ( y - 2 )^2 = 288[/tex]

Step-by-step explanation:

13a. Graph endpoints and find the center, and to find the center we can use the midpoint formula.

[tex]midpoint = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\ = (\frac{-9+3}{2},\frac{-4+8}{2})\\= (\frac{-6}{2},\frac{4}{2})\\ = (-3,2)[/tex]

13b. Use given points and use distance formula to find radius.

[tex]distance = \sqrt{({x_2-x_1})^2+({y_2-y_1})^2}\\= \sqrt{({3-(-9)})^2+({8-(-4)})^2}\\= \sqrt{({3+9})^2+({8+4})^2}\\=\sqrt{({12})^2+({12})^2}\\ =\sqrt{({12})^2+({12})^2}\\= \sqrt{144+144} = \sqrt{288} = 12\sqrt{2}[/tex]

13c. Refer back to 13a and 13b to setup the equation of the circle.

[tex]( x - h )^2 + ( y - k )^2 = r^2\\( x - (-3) )^2 + ( y - 2 )^2 = (12\sqrt{2})^2\\( x +3 )^2 + ( y - 2 )^2 = 288[/tex]

Answer:

  29

Step-by-step explanation:

We can use ...

  (a +b +c)² = a² +b² +c² +2(ab +bc +ca)

  9² = a² +b² +c² +2(26)

  a² +b² +c² = 81 -52 = 29

Step-by-step explanation:

We know the formula:

(a+b+c)² = a² + b² + c² + 2(ab+bc+ca)

Given:

a+b+c = 9 & ab+bc+ca = 26

Now putting the values in the above formula,

We get,

(9)² = a² + b² + c² + 2×26

81 = (a² +b² +c²) + 52

(a² +b²+c²) = 81-52

(a² + b² + c²) = 29 (Answer)

Answer:

128√5/3 mm³

Step-by-step explanation:

Since we are not told what to find, we can as well look for the volume of the pyramid

Volume of a square pyramid: V = (1/3)a²h

a is the side length of the square

h is the height of the pyramid

Given

a = 8mm

l² = (a/2)² + h²

l² = (a/2)² + h²

6² = (8/2)² + h²

h² = 6² - 4²

h² = 36 - 16

h² = 20

h = √20

Volume of a square pyramid =  (1/3)*8²*√20

Volume of a square pyramid = 1/3 * 64 * 2√5

Volume of a square pyramid = 128√5/3 mm³
