a) 97 93 92 90 90 90 86 =90

median of Edgars grades for his midterm is 90

99 93 93 89 88 88 86

median of Edgars grades for his trimester is 89

7)

(z+9+18)= z+27 (remember don't mix the numbers if they are attached to the x)

(z+18+9)= z+27 (because adding is both ways the same)

a) a + b =b + a

a) 6x^2

b)The surface area of a cube = 6a^2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, x is just the length of one side of a cube

c) The unit would be sq(squared) feet

Answer:

  G(0, 20)

Step-by-step explanation:

G = 2M -F

G = 2(7, 19) -(14, 18) = (14 -14, 38 -18)

G = (0, 20)

Additional comment

This formula for finding the end point from the midpoint and the other end can be derived from the fact that the midpoint is the average of the endpoints.

  M = (F+G)/2

  2M = F+G . . . . . multiply by 2

  G = 2M -F . . . . . subtract F

El área del triángulo es de 24.5 unidades cuadradas.

En este problema, procedemos a resumir el procedimiento como sigue:

1) Calculamos las longitudes de los segmentos de línea AB, BC y AC por medio de la ecuación de longitud del segmento de línea.

2) Determinamos el semiperímetro del triángulo.

3) Determinamos el área del triángulo mediante la fórmula de Herón.

Si tenemos que [tex]A(x,y) = (-3, 4)[/tex], [tex]B(x,y) = (4, 4)[/tex] and [tex]C(x,y) = (4, - 3)[/tex], entonces aplicamos el procedimiento como sigue:

Paso 1 - Longitudes de segmentos línea

Segmento AB

[tex]l_{AB} = \sqrt{[4-(-3)]^{2}+(4-4)^{2}}[/tex]

[tex]l_{AB} = 7[/tex]

Segmento BC

[tex]l_{BC} = \sqrt{(4-4)^{2}+[(-3)-4]^{2}}[/tex]

[tex]l_{BC} = 7[/tex]

Segmento AC

[tex]l_{AC} = \sqrt{[4-(-3)]^{2}+(-3-4)^{2}}[/tex]

[tex]l_{AC} = 7\sqrt{2}[/tex]

Paso 2 - Cálculo del semiparámetro

[tex]s = \frac{l_{AB}+l_{BC}+l_{AC}}{2}[/tex]

[tex]s = \frac{14+7\sqrt{2}}{2}[/tex]

[tex]s = 7 + \frac{7\sqrt{2}}{2}[/tex]

Paso 3 - Cálculo del área del triángulo

[tex]A = \sqrt{s\cdot (s-l_{AB})\cdot (s-l_{BC})\cdot (s-l_{AC})}[/tex]

[tex]A = 24.5[/tex]

El área del triángulo es de 24.5 unidades cuadradas.

Answer:

-8 and -6.

Step-by-step explanation:

Let the first even integer be a.

Since the second is a consecutive even integer, it is given by (a + 2).

Half of the smaller (i.e. a) is equal to two more than the larger (i.e. a + 2). In other words:

[tex]\displaystyle \frac{a}{2} = (a + 2) + 2[/tex]

Solve for a:

[tex]\displaystyle \begin{aligned}\displaystyle \frac{a}{2} &= (a + 2) + 2\\ \\ \frac{a}{2} &= a + 4\\ \\ a &= 2a + 8 \\ \\ a &= -8 \end{aligned}[/tex]

In conclusion, the two even, consecutive integers are -8 and -6.

Answer:

1/10

Step-by-step explanation:

8 black marbles, 5 white marbles and 12 red marbles = 25 marbles

P(red) = red/total = 12/25

Remove the marble

8 black marbles, 5 white marbles and 11 red marbles = 24 marbles

P(white) = white/total = 5/24

P(red, remove,white) = 12/25 * 5/24

                                   =12/24 * 5/25

                                   =1/2 * 1/5

                                   =1/10

Step-by-step explanation:

Total balls = 12 + 5 + 8 = 25 marbles

Probability of getting white marbles = 5/24

Probability of red marbles = 12/24 = 1/2

Now

Probability = 1/2 × 5/24 + 1

Probability = 1/2 × 5/25

Probability = 5/50

Probability = ⅒

Answer:

40-15x=18

Step-by-step explanation:

Multiply both sides of 2 - 3/4x = 9/10 by twenty to get

20*2 - 20*3/4*x = 20*9/10

which is 40 - 15x = 18

This should be as far as you need to go, but incase you need to go further,

subtract 40 to both sides

multiply both sides by -1 to get rid of the negatives infront of the x

then divide both sides by 15 to get

x=22/15

and yes, when you solve for x, it is a fraction, but just incase if its needed, I included it. Hope this helps in the future! Let me know if any more questions you have on this problem.

Answer:

y is the dependent variable and x is the independent variable

Step-by-step explanation

The number on the right of the equal sign is always the independent variable and the number on the left is always the dependent variable.

independent variable = dependent variable +5

Answer:

Ratio should be equal so ratio is 3:3

The ratio of the triangles to circles in the diagram below would be; 1: 1

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained.

Thus, there are three circles and three triangles shown in the figure.

Therefore, the ratio will be;

three circles: three triangle

3 : 3

1: 1

Hence, the ratio of the triangles to circles in the diagram below would be; 1: 1

A.)

Total Number of students = 60

Since each candidate passed in atleast one of English and Math ; the none of the students failed.

Percentage who passed :.

Mathematics only = 20%

English only = 40%

Since, no one failed ; percentage that passed both = 100% - (40+20)% = 40%

Number who passed Mathematics only :

20% × 60 = 12 students

Number that passed English only :

40% × 60 = 24 students.

Number that passed both = (40% × 60) = 24 students

Number that passed English = (Number that passed English only + Number that passed both) = 24 + 24 = 48

.Number that passed mathematics = (Number that passed Maths only + Number that passed both) = 12 + 24 = 36

2.)

Total daddy has = 50

Half given to mummy = 1/2 × 50 = 25

Amount given to houseboy = 10

Amount left = 50 - (25 + 10) = 15

Fraction of Amount left = 15/50 = 3/10

C.)

Length of cuboid = 12

Height = 8 cm

Volume of cuboid = 480

Width = w

Recall :

Volume = Length × width × height

480 = 12 × 8  × w

480 = 96w

w = 490 / 96

w = 5

Width of the cuboid = 5

The surface area of a cuboid : 2(lh + lw + hw)

Hence,

2([(12×8) + (12×5) + (8 ×5)]

2(96 + 60 + 40)

2(190)
