Answer:

A = 94 square cm

Step-by-step explanation:

Surface Area of a Closed Box

The surface area of a rectangular prism of dimensions x, y, and z is given by:

A = 2(xy + yx + xz)

The dimensions of a closed box (a rectangular prism) with dimensions x=3 cm, y=5 cm, and z=4 cm is:

A = 2(3*5 + 5*4 + 3*4)

Calculating:

A = 2(15 + 20 + 12)

A = 2(47)

A = 94 square cm

Answer:

Costo de un taco = x = $ 92.4

Costo de una tosada = y = $ 306

Step-by-step explanation:

Representemos:

Costo de un taco = x

Costo de una tosada = y

Compraste 5 tacos y dos tostadas $ 150.50

5x + 2y = 150,50 ..... Ecuación 1

si por 4 tacos y tres tostadas tu prima pagó $ 549.00

4x + 3y = 549 ........ Ecuación 2

Combinando ambas ecuaciones

5x + 2y = 150.50 ..... Ecuación 1

4x + 3y = 549 ........ Ecuación 2

Multiplica la ecuación 1 por 4 y la ecuación 5 por 5 para eliminar x

20x + 8y = 602 ..... Ecuación 3

20x + 15y = 2745 ...... Ecuación 4

Reste la ecuación 3 de 4

7 años = 2143

y = 2143/7

y = 306.14285714

Aproximadamente = y = $ 306

Resolviendo para x

5x + 2y = 150.50 ..... Ecuación 1

5x + 2 (306) = 150.5

5x + 612 = 150

5x = 612 - 150

5 veces = 462

x = 462/5

x = $ 92.4

Por lo tanto,

Costo de un taco = x = $ 92.4

Costo de una tosada = y = $ 306

Step-by-step explanation:

The horizontal asymptote of the equation y=[tex](3x-1)/(x+3)[/tex] is 3.

Given an equation y=[tex](3x-1)/(x+3)[/tex] and we are required to find the horizontal asymptote of the equation.

Equation is like a relationship between two or more variables expressed in equal to form. It may be linear equation, quadratic equation or cubic equation. Equation of two variables look like ax+by=c.

Put x=0 in the equation,

y=[tex](3x-1)/(x+3)[/tex]

Horizontal asymptote can be found by dividing the coefficients of the leading terms of the equation. We have to divide the coefficients.

Horizontal asymptote=3x/x

=3

Hence the horizontal asymptote of the equation y=[tex](3x-1)/(x+3)[/tex] is 3

Answer:

The cost for Issac to  swim for 12 months is $250.

Hence, option 'B' is true.

Step-by-step explanation:

Given that the gym pass costs $30 for the first month, so

Each month after that, the cost is $20 per month, so the sequence becomes

a₁, a₂, a₃, a₄, a₅, ...

30, 50, 70, 90, 110, ...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]50-30=20,\:\quad \:70-50=20,\:\quad \:90-70=20,\:\quad \:110-90=20[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=20[/tex]

now, we have

so substituting a₁ = 30 and d = 20 in the nth term of the sequence

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=20\left(n-1\right)+30[/tex]

[tex]a_n=20n+10[/tex]

Thus, the nth term of the sequence is:

[tex]a_n=20n+10[/tex]

Determining the cost for Issac to  swim for 12 months:

As we have already determined the nth term of the sequence such as

[tex]a_n=20n+10[/tex]

now substituting n = 12

[tex]a_{12}=20\left(12\right)+10[/tex]

[tex]a_{12}=240+10[/tex]

[tex]a_{12}=250[/tex]

Therefore, the cost for Issac to  swim for 12 months is $250.

Hence, option 'B' is true.

[tex]\boxed {\boxed {\sf C. \ 4 \ inches}}[/tex]

Step-by-step explanation:

Circumference is the perimeter of a circle. It can be found using the formula:

[tex]c= \pi d[/tex]

However, we are given the radius.

The formula can be rewritten as:

[tex]c= \pi 2 r[/tex]

We know the circumference is 25.12 inches.

[tex]25.12 \ in = \pi 2r[/tex]

Let's round pi to 3.14

[tex]25.12 \ in = (3.14) 2r[/tex]

We want to solve for the radius, so we must isolate it.

Divide both sides by 3.14 because the inverse of multiplication is division.

[tex]25.12 \ in / 3.14= (3.14 ) 2r / 3.14[/tex]

[tex]8 \ in = 2r[/tex]

Divide both sides by 2.

[tex]8 \ in / 2 = 2r/2[/tex]

[tex]4 \ in = r[/tex]

The radius of the disc is 4 inches.

Answer:

70. g NaCl

Step-by-step explanation:

For every one mole of a substance, there is a molar mass that coincides with the values of the periodic table. NaCl has a molar mass of 58.44g (Na+Cl). You then take this molar mass and multiple it by the number of moles asked (1.2) to find the grams present.

58.44g * 1.2mol = 70.128g

Then you would round to 2 sig figs to get 70. g of NaCl

Answer: 11.4 m

Step-by-step explanation:

The scenario depicted is that of a right angled triangle with the 7 meters being the base and the 9 meters being the height.

The length of the ladder will therefore be the Hypothenuse.

Using the Pythagorean Rule:

a² + b² = c²

with c being the hypothenuse

7² + 9² = c²

49 + 81 = c²

c²= 130

c = √130

c = 11.4 m
