Answer:x =18

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

The sum of angles in this shape is equal to 360° one of the angle is given as 90°

so 90 + 5x = 360

5x = 270 divide both sides by 5

x = 54

Answer:

what

Step-by-step explanation:

Answer:

A

Step-by-step explanation: You are given a specific direction, while the rest aren't certain.

Answer:

0.005

Step-by-step explanation:

[tex]0.5 \% \: = \frac{0.5}{100} = 0.005[/tex]

Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

180 + 8x = 160 + 6x

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

180 + 8(-10) = 160 + 6(-10)

180 - 80 = 160 - 60

100 = 100

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.

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

Correct Choice: B. 294

Answer:

Answer is B = 294

Step-by-step explanation:

Answer:

The answer is 16%

Step-by-step explanation:

use the percent error formula.

[tex]\frac{|E-T|}{|T|} *100[/tex]

in this problem,

e= 75

t=90

substitute and solve.

[tex]\frac{|75-90|}{|90|} *100\\\frac{|-15|}{|90|}*100\\\\ .16667*100\\[/tex]

16%

we are dealing with percents so rounding to nearest whole number will suffice.

hope this helps!

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

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

Am I right?

Answer:

The total cost of the material was $31.35

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:

y= x+1

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).

Answer:

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

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.

la respuesta para la ecuación es -5

Answer:

Step-by-step explanation. Cccccccccccc

:

Answer:

the first one

Step-by-step explanation:

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°
