Answer: 75

Step-by-step explanation:  

As you can see in the question, the experimental probability is 1/5. So, we take that 5 and divide it into 375. 375 divided by 5 is 75. There you go!

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:

Y=8x-1  The y intercept is -1    so mark -1 on the graph  using up/over from the y intercept you move up eight over one.

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: 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

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:

slop intercept form = y = 5/4x - 3.5

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

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:

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

Answer:

$3975

Step-by-step explanation:

Given data

base salary of $350 per week

6% commission on sales

If sales is  $3,750

Commision will be

=6/100* $3,750

=0.06* $3,750

=$225

Hence the earning for the week is

=3,750+225

=$3975

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

If $5=20% we have to find how money is the 100%.

$5-----------------20%

x------------------100%

x=($5*100%) / 20%=$25

[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.

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:

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
