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:

1)  3x+4y=8

4y=-3x+8

4y/4=-3x/4+8/4

y=-3/4x+2

slope=-3/4

Y intercept=2

2) 9x+35=-5y

-5y/-5=9x/-5+35/-5

y=-9/5x-7

slope=-9/5

y intercept=-7

3)2y-6=-6x

2y−6+6=−6x+6

2y /2−6x/2+6 /2

y=−3x+3

slope is -3x

y intercept is 3

Answer:

n, +, 2.35

So the person above me is right i just did the assignment!

The variable in the expression is = n

The operation in the expression is = addition ( + )

The constant in the expression is = 2.35

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = n + 2.35   be equation (1)

Now , the expression is simplified as

The variable in the expression is = n

Answer:

34 units

Step-by-step explanation:

Since the triangles are equal, the bottom length of triangle CAD will be the same as the bottom length of BAD. This means that the total length of the bottom of triangle ABC is 6 (3 + 3).

Next, you need to find the length of AC and again, since they're the same triangle, AB will be the same as AC, 14.

The three side lengths of the triangle will be 6, 14, and 14, so the perimeter is

6 + 14 + 14 = 34 units

Hence the earning for the week is

=3,750+225

=$3975

Answer:

the inequality function be p ≤ 13

Step-by-step explanation:

The inequality function be

p ≤ 8 + 5

p ≤ 13

Here p denotes the price

It can spend the total of $13 that lies between the $8 and $5 off coupon

Hence, the inequality function be p ≤ 13

Paper route earnings each week=($87.8-$37.8) / 10 =$5

Answer: 12ab^3

Step-by-step explanation:

The length of the rectangle will be gotten by dividing the area by the width. This will be:

Length = 72 a^3b^4 / 6a^2 b

= 72 × a × a × a × b × b × b × b / 6 × a × a × b

= 12 × a × b × b × b

= 12ab^3

Step-by-step explanation:

Answer:

m=22

Step-by-step explanation:

The angles of the triangle will be equal to 180.

m + 5m + m+26 = 180

Combine like terms

7m+26=180

Subtract 26 on both sides

7m=154

Divide by 7

m=22

Answer:

m=22

Step-by-step explanation:

Triangle has 180 degrees in total

m+5m+(m+26)=180

solve

6m+m+26=180

7m=180-26

7m=154

m=22

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

Answer: The answer is C

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
