Amare is buying museum souvenirs. He buys 3 animal figures
and 6 bookmarks for $33. Later he goes back to buy 3 more
figures and return 3 of the bookmarks, spending another $6.
In the system, fis the price of a figure and b is the price
Al Pisto
of a bookmark.
3f + 6b = 33
3f-3b = 6
How much does each figure cost? How much does each bookmark cost?

Answer:

D) 83

Step-by-step explanation:

x+7=90

x= 83

Hope it's helpful...

Answer:

D

Step-by-step explanation:

The diagonals of a kite are at right angles to each other, then

x + 7 = 90 ( subtract 7 from both sides )

x = 83 → D

[tex]\huge\boxed{Que \ es \ un \ variable \ ?\hookleftarrow}[/tex]

✐ En matemáticas, una variable es un símbolo que funciona como marcador de posición para expresiones o cantidades que pueden variar o cambiar; se utiliza a menudo para representar el argumento de una función o un elemento arbitrario de un conjunto. Además de los números, las variables se utilizan comúnmente para representar vectores, matrices y funciones.

Answer:

a) y(x) = (x + 2)^2 -2

b) minimum

c) (-2, -2)

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

• If a > 0 then vertex is minimum

• If a < 0 then vertex is maximum

Given

y = x² + 4x + 2

(a)

To complete the square

add/ subtract ( half the coefficient of the x- term)² to x² + 4x

y = x² + 2(2)x + 4 - 4 + 2

y = (x + 2)² - 2

(b)

Since a = 1 > 0 then vertex is minimum

(c)

(h, k ) = (- 2, - 2 ) ← coordinates of vertex

Cubic feet of toys box hold = 30 cubic feet

Step-by-step explanation:

Missing information;

Length of toy box = 5 feet

Width of toy box = 3 feet

Height of toy box = 2 feet

Find:

Cubic feet of toys box hold

Computation:

Cubic feet of toys box hold = Volume of rectangular box

Volume of cuboid = [l][b][h]

Cubic feet of toys box hold = [5][3][2]

Cubic feet of toys box hold = 30 cubic feet

Answer:

Add 3 to both sides of the equation

Solution:

The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left ([tex]x^2 - 8x + 13[/tex]) into an expression that is a perfect square. So what number should you add to both sides such that [tex]x^2 - 8x + (13 + j)[/tex] can be factored into [tex](x-p)^2[/tex] ? Well, we can approach it like this:

Since [tex](x-p)^2[/tex] can be turned into [tex]x^2 -2px + p^2[/tex], and our original form was [tex]x^2 - 8x + (13 + j)[/tex], we quickly realize that [tex]-2px = -8x[/tex]. From there, we can easily tell that [tex]p = 4[/tex]

Plug this into our last value [tex]p^2[/tex] to get 16. Therefore, if we compare this with our original equation again [tex]x^2 - 8x + (13 + j)[/tex], we notice that 13 + j = 16.

Thus, j = 3 for the last answer.

Add 3 to both sides of the equation.

Note: With more practice, you will quickly gain enough intuition to notice that [tex]x^2 - 8x + 13[/tex] is very close to [tex]x^2 - 8x + 16[/tex] which can be factored into [tex](x-4)^2[/tex]. But for now, the solution above will suffice. I hope this helps :))

Answer: 14:3

Step-by-step explanation:

Given

Ratio between students(s) to female(f) adults is 7:6

while ratio between female(f) to male(m) is 4:1

So, we can write

[tex]\Rightarrow \dfrac{s}{f}=\dfrac{7}{6}\quad \ldots(i)[/tex]

Also, we can write

[tex]\Rightarrow \dfrac{f}{m}=\dfrac{4}{1}\quad \ldots(ii)[/tex]

Multiply both equations

[tex]\Rightarrow \dfrac{s}{f}\times \dfrac{f}{m}=\dfrac{7}{6}\times \dfrac{4}{1}\\\\ \Rightarrow \dfrac{s}{m}=\dfrac{14}{3}[/tex]

So, the ratio of the students to male adults is 14:3 .

Answer:

8.8

Step-by-step explanation:

Normally, to find the distance between two points, you would use the distance formula, but these two points have the same x-coordinate, meaning they will form a vertical line when connected. To find the length of a vertical line you find the distance between the y-coordinates, in this case -4.7 and 4.1. Finding the distance is the same as finding the absolute value of the difference:

|4.1 -(-4.7)|

|4.1 + 4.7|

|8.8|

Answer:

[tex]\boxed {\boxed {\sf D. \ 30 \ feet}}[/tex]

Step-by-step explanation:

The area of a square is found by multiplying the base and the height, but since all the sides are equal, it is equal to multiplying a side by another side.

[tex]a=s*s[/tex]

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

We know the square garden has an area of 900 square feet. We can substitute this value in for a.

[tex]900 \ ft^2=s^2[/tex]

Since we are solving for the side, we have to isolate the variable s. It is being squared. The inverse of a square is the square root, so we take the square root of both sides.

[tex]\sqrt {900 \ ft^2}= \sqrt{s^2}[/tex]

[tex]\sqrt {900 \ ft^2}=s \\[/tex]

[tex]30 \ ft=s[/tex]

One side of the garden is equal to 30 feet and choice D is correct.

Step-by-step explanation:

Area of square garden=a^2

ATQ

➝a^2=900 sq.feet

➝a=√900

➝a=30feets

Volume = 1526.04 cubic units

Step-by-step explanation:

Formula for volume of a cone:

V = πr²h/3

If we use 3.14 for pi, we get 1526.04:

V = 3.14(9)^2(18)/3

V = 1526.04

Answer:

0.08, 8 hundreths, 8 x 1/100

Step-by-step explanation:

The first digit before the decimal is a unit.

The first digit after the decimal point is called a tenth

The second digit after the decimal point is called hundreths

The third digit after the decimal point is called a thousandths

The 8 is the second digit after the decimal point.

Therefore the answer is eight hundreths or represented by the decimal form of 0.08

It is also 8 x 1/100 because if we multiply this we get 0.08

g(x)=2x^2

Step-by-step explanation:

Multiplying by a constant will stretch the graph as shown. The graph of g(x) appears to pass through (1,2), so g(x)=2x^2 is a reasonable guess (I can't see the answer choices).
