Write the equation of a line that is perpendicular to the line that passes through (4,−3)and (−7,8).

Answers

Line perpendicular to a given line is = 1/m

To find m, use m =y2-y1/x2-x1 formula

m = (8-(-3))/(-7-4)

m = 11/-11,

m = -1

Use y= mx+c to find equation of line

Plug in a pair of values,

-3= -1(4)+ c

c= 1

Thus, equation is:

y = -x+1

Equation of line perpendicular to this line is:

You have $125.60 in quarters and
dimes. There is 956 coins
altogether. How many quarters do
you have?

Answers

Answer:

Quarters = q = 200

Dimes = d = 756

Step-by-step explanation:

Let

Dimes = d

Quarter = q

Value of each Dime = 0.10

Value of each Quarter = 0.25

d + q = 956 (1)

0.1d + 0.25q = $125.60 (2)

From (1)

d = 956 - q

Substitute d = 956 - q into (2)

0.1d + 0.25q = $125.60

0.1(956 - q) + 0.25q = $125.60

95.6 - 0.1q + 0.25q = $125.60

- 0.1q + 0.25q = 125.60 - 95.6

0.15q = 30

Divide both sides by 0.15

q = 30 / 0.15

= 200

q = 200

Substitute q = 200 into (1)

d + q = 956

d + 200 = 956

d = 956 - 200

= 756

d = 756

Therefore,

Quarters = q = 200

Dimes = d = 756

10. Six cases of paper cost $159.98. How much does one
case cost? explain
HELP!!!

Answers

Answer:

$26.6633333333

Step-by-step explanation:

You divide $159.98 by 6 lol

Answer:
$26.66 per case

Explanation:

We want to find the cost per case. Therefore we must divide the cost by the number of cases.
cost per case= cost/cases
We know that it costs $159.98 for 6 cases of paper.
cost per case= $159.98/6 cases
Divide.
cost per case= $26.66333333333333/case
Round to the nearest cent or hundredth. The 3 in the thousandth place tells us to leave the 6 in the hundredth place.
cost per case ≈$26.66

It costs about $26.66 per case of paper.

Astrid is in charge of building a new fleet of ships. Each ship requires 40 tons of wood, and accommodates
300 sailors. She receives a delivery of 4 tons of wood each day. The deliveries can continue for 100 days at
most, afterwards the weather is too bad to allow them. Overall, she wants to build enough ships to
accommodate at least 2100 sailors.
How much wood does Astrid need to accommodate 2100 sailors?

Answers

Answer:

it requires 280 ton of wood

Step-by-step explanation:

one ship can accommodate 300 sailors so for 2100 sailors you need

2100/300

7 ships

and as I ship require 40 tons of wood then 7*40

280 tons

then

he can get 4 ton of wood per day

then

280/4

70 days

therefore he needs wood for 70 days to accommodate 2100 sailors

O B. 6(49) = 6(50 – 1) = 6 - 50 – 6.1 = 300 – 6 = 294
C. 6(49) = 6(50 – 1) = 6 - 50 – 50 · 1 = 300 – 50 = 250
O D. 6(49) = 6(50 – 1) = 6.50 – 1 = 300 – 1= 299

Answers

Answer:

Correct Choice: B. 294

Step-by-step explanation:

The distributive property allows modifying expressions in the form of a(b + c) into the form ab+bc.

If we wanted to express the product 6*49 as 6*(50-1), then applying the distributive property we have:

6*(50-1)=6*50-6*1

6*(50-1)=300-6

6*(50-1)=294

SITUACIÓN 2: Confecciones
Margarita tiene un taller de confecciones y está elaborando mascarillas de tela. Esta semana sus pedidos de mascarillas han disminuido a la mitad por lo que deberá comprar 50 % menos de tela para confeccionar mascarillas. ¿Cuál de las siguientes representaciones muestra de mejor manera las cantidades de tela que necesitará Margarita cada semana? Argumenta tu respuesta.

Answers

Answer:

La representación que muestra de mejor manera las cantidades de tela que necesitará Margarita cada semana es:

Representación A.

Step-by-step explanation:

Como puedes identificar del enunciado, es ÉSTA semana en la cual los pedidos de mascarillas han disminuído a la mitad (o 50%, que sería lo mismo), por lo tanto, es en esta semana cuando el pedido de tela va a disminuir a la mitad, además debes identificar que el enunciado hace énfasis en que sus pedidos han disminuído, por lo cual puedes deducir que regularmente sus pedidos de mascarillas son el doble de lo solicitado en esta semanal, considerándose lo ocurrido en ésta semana como una anomalía, teniendo en cuenta esto, la próxima semana seguramente los pedidos volverán a la normalidad, necesitándose el doble de tela que en esta semana.

En la representación A puedes ver que se representa la cantidad de tela de ésta semana con un rectángulo, lo cual podría considerarse una unidad, y ya que sabemos que la próxima semana las confecciones de mascarillas seguramente regresarán a la normalidad, es lógico que la cantidad de tela requerida será el doble, así pues, si en esta semana se requirió una unidad de tela, en la proxima semana se requerirán dos, por lo cual la única opción que cumple con estos parámetros es la A.

Bobby charges $10. per lawn he mows, and an additional $5. per hour.
a) Find the independent and the dependent variables.
b) Write a linear function that models the wage of Bobby per lawn.
c) If Bobby work for 3.5 hours on a lawn, how much does he earn?

Answers

Answer:

a) independent = hours

   dependent = wages

b ) W = 10 + 5h

c)27.50

Step-by-step explanation:

The independent variable is the one that you change which is the number of hours that it takes

The dependent variable is the variable that changes based on the independent variable.  The wages depends on the hour worked so the wages are the independent variable

The wages equal the fixed cost plus the hourly rate times the number of hours  where W is the wages and h is the number of hours

W = 10 + 5h

W = 10 + 5( 3.5)

    = 10 + 17.5

    = 27.5

Answer:

It is B

Step-by-step explanation:

Plug each value possible into the equation

(48+x) / 31   =    x/15

If both sides are equal when you plug x in, it's correct

If they aren't equal, it is wrong.

How did I get this equation?

Lets use proportions to solve.

Since they are similar, (the two triangles are similar, meaning that they have the same ratio of the y and x axis values) you can use proportions meaning you make it so x over 15 is equal to the total length by the total bottom length.

If you plug 45 in as x, you get (48 + 45) divided by 31 is equal to 45/15

If you simplify the equation, you get 93 divided by 31 is equal to 3, of which 93 divided by 31 is 3

I think you know that 3=3

so it is correct.

Answers

Answer:

x = 21

Step-by-step explanation:

By the corresponding angle theorem, we can find that the measure of the smaller angle made by transversal and m is 54°.

Using the vertical angle theorem, we can find that the missing angle is the triangle, the two known angles are 4x and 2x, is also 54°.

Since the sum of the interior angles of a triangle is always equal to 180°, we can make the equation:

2x + 4x + 54 = 180

Now we solve for x. Subtract 54 from both sides and combine like terms.

6x = 126

Divide both sides by 6.

x = 21

and now we have found the value of x. x = 21.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

x=21°

Step-by-step explanation:

Relations Between Angles

We need to recall two basic relations:

* Two angles opposite by crossing lines are always equal.

* The sum of angles in a triangle is 180°

We'll add some variables to the image, so x is easier found. Please check the image below.

The angles U and 54° are opposite and they must be equal, thus U=54°

Since m and n are parallel and they are crossed by a line, the angles V and U are equal, thus V=54°

Finally, The sum of the angles inside the triangle RST must be equal to 180°:

2x+4x+54=180

Joining like terms:

6x=180-54=126

Solving:

x=126/6

x=21°

Jasmine is in charge purchasing tubes of silicone sealant, used for finishing restroom facilities. She finds that she is able to purchase silicone sealant in cone tubes. She knows that a jumbo cone of sealant has a top diameter of 12 inches and a height of 14 inches, and a regular cone of sealant has a top diameter of 6 inches and a height of 7 inches. Jasmine believes that with her order of sealant, that she can get the same amount of silicone sealant from two regular cones as from one jumbo cone.

Answers

The question attached is:

Is Jasmine correct about the silicone sealant cones?

If you think Jasmine is correct to explain, why.

Answer:

Jasmine is correct about the silicone sealant cones

Step-by-step explanation:

Given that:

Jumbo cone of sealant has a top diameter of 12 inches and a height of 14 inches, Suppose Jasmine orders or demands for two regular cones of regular sealant, definitely, that will be equal to the Jumbo cone of sealant.

This is because the top diameter when put together in a Jumbo cone will give an actual result as a Jumbo cone, for as much as 6 × 2 = 12 inches (top diameter) and 7 × 2 = 14 inches (height).
