Substitute n=3 into the problem

6([tex]3^{3}[/tex])-2([tex]3^{2}[/tex]) +3-4

Then figure out squared and power by 3

6(27)-2(9)+3-4

Next multiply

162-18+3-4

Finally, add and subtract

144+3=147

147-4=143

Given is the figure of a kite.

In a kite, diagonals intersects each other at right angles.

Therefore,

[tex](2x + 6) \degree + 4x \degree + 90 \degree = 180 \degree \\ \\ (2x + 6 + 4x) \degree = 180 \degree - 90 \degree \\ \\ (6x + 6) \degree = 90 \degree \\ \\ 6x + 6 = 90 \\ \\ 6x = 90 - 6 \\ \\ 6x = 84 \\ \\ x = \frac{84}{6} \\ \\ x = 14 \\ \\ (3x + 6) \degree = (3 \times 14 + 6) \degree = 48 \degree \\ \\ 4x\degree = 4 \times 14 \degree= 56 \degree \\ \\ (2x + 6) \degree = (2 \times 14 + 6) \degree = 34\degree[/tex]

Two point form

Answer:

There are 76 students:

g + b = 76

girls is 13 more than twice the boys:

g = 2b + 13

replace g with 2b + 13 in 1st equation

2b+13+b = 76

3b + 13 = 76

3b = 63

b = 21 boys

g = 76-21 = 55 girls

Step-by-step explanation:

Una ecuación cuadrática es una ecuación que tiene la siguiente forma:

ax² + bx + c = 0

Donde:

a, b y c: coeficientes numéricos que acompañan a la incógnita.

Ahora bien, una función cuadrática es basicamente la misma ecuación cuadrática pero representada graficamente en un plano cartesiano.

Para que una ecuación o función sea cuadrática es absolutamente necesario y obligatorio que su expresión en forma de ecuación tenga el elemento "ax²", pues el "cuadrado" que es el exponente 2 que eleva la incógnita es lo que le da la característica de ecuación o función cuadrática.

Si el coeficiente que acompaña al x², es decir, el valor de a es cero, automaticamente pierde la condición de ser una función o ecuación cuadrática pues dicho término se hace cero su valor. En otras palabras, si x es un número cualquiera y está representado como incógnita, ¿qué sucede cuando multiplicas cualquier número por cero?, en este caso, el resultado es igual a cero:

Ejemplo:

0x² = 0 * x² = 0.

Por tanto, si el término cuadrático se hace cero, ya pierde la condición de cuadraticidad, y su gráfico no sería de forma parabólica, solo quedaría los términos bx + c, pero eso ya pertenece a una ecuación lineal o función afín.

Espero esto te sirva.

Answer: 50 students

Step-by-step explanation:

Let the number of students who went on the trip be x

The information given in the question can be formed into an equation as:

30% of x = 15

30/100 × x = 15

0.3 × x = 15

0.3x = 15

x = 15/0.3

x = 50

50 students went on the trip

Answer: 45 liters

Step-by-step explanation:

If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.

15 / 2 = 7.5.

Roger can jar 7.5 liters of jam every day.

Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.

7.5 x 6 = 45.

Therefore, Roger can jar 45 liters of jam in 6 days.

7) A regular quadrilateral is a square, so any angle on a square is 90°, A

8) Looking at the shape, it appears to be B (4 sides and symmetrical)

9) The shape appears to be B (4 sides, opposite angles are equal, all sides are equal)

I forgot the formula for a trapezoid, but I'm sure you use it or their properties to find the rest.

Solution 1.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 4 appeared = 8

Probability

= No. of preferred outcomes/Total number of outcomes

= 8/80

= 1/10

= 0.1

Solution 2.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 2 appeared = 22

Probability

= No. of preferred outcomes/Total number of outcomes

= 22/80

= 11/40

= 0.275

2s to expect if dice is rolled 400 times

= 0.275 × 400

= 110

Step-by-step explanation:

Answer:

Q2)

We have food for 400 people, and it will last for 23 days.

Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:

23 days = K/400 people.

Then we get:

(23 days)*(400 people) = K = 9200 days*people.

Now if we increase the number of people by 60, we get.

people = 460

Then the number of days that this will last is:

D = (9200 days*people)/460 people = 20 days.

The food will last for 20 days.

Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:

40 = k*200

With this, we can find the value of k

40/200 = k = 0.2

Then the proportional relationship is:

y = 0.2*x

a) We need to replace x by 15.

y = 0.2*15 = 3

y = 3

b) We need to replace y by 8.

8 = 0.2*x

8/0.2 = x = 40

x = 40

Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.

Then we get:

8 = k/30

Then the value of k is:

8*30 = k = 240

then the relationship is:

y = 240/x

a) we need to replace x by 4

y = 240/4 = 60

y = 60

b) we need to replace y by 360

360 = 240/x

360*x = 240

x = 240/360 = 0.666...

x = 0.666...
