Answers

Answer 1

Answer:

19. x = 65

20. x = 12

21. x = 35, y = 85

Step-by-step explanation:

19. 2x -10 = 120

2x (-10 + 10) = (120 +10)

2x/2 = 130/2

x = 65

20. 2x + 4x + 108 = 180

6x + (108 - 108) = (180 - 108)

6x/6 = 72/6

x = 12

21. 2x + 25 = 3x - 10

2x + (25 - 25) = 3x (- 10 - 25)

(2x - 3x) = (3x - 3x) - 35

-x/-1 = -35/-1

x = 35

3x - 10 + y = 180

3(35) - 10 + y = 180

105 - 10 + y = 180

(95 - 95) + y = (180 - 95)

y = 85

Multiply. Use the greatest common factor to write each answer in simplest form. 24 x 5/6

Answers

Answer:

120

Step-by-step explanation:

The common denominator of 24/1 and 5/6 is 6 so you multiply 24/1 by 6 which equal 144/6. Then you multiply 144/6 and 5/6 which equals 720/6. When you simplify it, it equals 120.

A patio is designed using two types of tiles. The tiles are similar isosceles triangles. The lengths of the sides of the larger triangle are 6 inches, 6 inches, and 4 inches. Which one of these could be the side measurements of the smaller triangle?

Answers

Ommited Answer Choices:

A. 4 inches, 4 inches, 4 inches

B. 3 inches, 3 inches, 3 inches

C. 3 inches, 3 inches, 2 inches

D. 2 inches, 2 inches, 3 inches

Answer:

C. 3 inches, 3 inches, 2 inches

Step-by-step explanation:

The ratio of the corresponding lengths of two similar polygons will always be equal.

Thus, the ratio of the smaller sides of both similar isosceles ∆ should equal the ratio of the other sides.

Thus, from the options given, the side measurements that could be that of the smaller triangle are: 3 inches, 3 inches, 2 inches.

This is because: ratio of one of the equal side of the larger triangle to one of the equal side of the smaller triangle equal ratio of the shortest side of the bigger triangle to the shortest side of the smaller triangle.

Thus: 6/3 = 4/2 = 2.

Answers

Answer:

x= 6

Step-by-step explanation:

3(x + 4) = 2x + 4x - 6

3x + 12 = 2x + 4x - 6

3x + 12 = 6x - 6

-3x = -18

x= 6

hope it helps

if it helps you, pls give me the brainliest.

Answer:

x = 6

Step-by-step explanation:

3(x + 4) = 2x + 4x - 6

~Distribute the left side

3x + 12 = 2x + 4x - 6

~Combine like terms on the right side

3x + 12 = 6x - 6

~Subtract 12 to both sides

3x = 6x - 18

~Subtract 6x to both sides

-3x = -18

~Divide -3 to both sides

x = 6

∠GHJ and ∠MHJ are complementary. If m∠GHJ=(6x)° and m∠MHJ=18°, find the value of x.

Answers

Answer:

The value of x = 12

Step-by-step explanation:

Here, we are to find the value of x

If the two angles are supplementary, it means that they add up to be 90 degrees

Thus;

∠GHJ + ∠MHJ = 90

6x + 18 = 90

6x = 90-18

6x = 72

x = 72/6

x = 12

Un robot en Marte tiene los siguientes desplazamientos antes de lograr encontrar el lugar con las coordenadas indicadas para empezar a analizar . Su desplazamiento es de: 25 m al Sur, 35 m a 15° partiendo del Este hacia el Norte y por último 20 m a 37° partiendo del Oeste hacia el Norte. Encuentra el desplazamiento de su recorrido

Answers

Answer:

El desplazamiento total del robot es de aproximadamente 17.4 m 12.35° al sur del este

Step-by-step explanation:

El movimiento del robot en Marte se da como sigue;

1) El desplazamiento sur = 25 m

2) El desplazamiento 15 ° al norte del este = 35 m

3) El desplazamiento 37 ° al norte del oeste = 20 m

Por lo tanto, tenemos la moción en forma vectorial;

1) -25[tex]\hat j[/tex]

2) 35·cos(15°)[tex]\hat i[/tex] + 35·sin(15°)[tex]\hat j[/tex]

3) -20·cos(37)[tex]\hat i[/tex] + 20·sin(37°)[tex]\hat j[/tex]

Por lo tanto, tenemos el desplazamiento resultante total, R, del robot está dado por la suma de los vectores como sigue;

R =  (35·cos(15°) - 20·cos(37)) [tex]\hat i[/tex] + (35·sin(15°) + 20·sin(37°) - 25)[tex]\hat j[/tex]

R = 17.8346937192 [tex]\hat i[/tex] - 3.9050329583 [tex]\hat j[/tex]  

La magnitud de R = √ ((17.8346937192) ² + (-3.9050329583) ²) ≈ 17.4 m

La magnitud de R ≈ 17,4 m

La dirección de R = Arctan ((- 3.9050329583) / (17.8346937192)) ≈ -12.35 °

La dirección de R ≈ -12,35 °

La dirección es aproximadamente 12,35 ° al sur del este

El desplazamiento total del robot es de aproximadamente 17.4 m 12.35 ° al sur del este

???????                      for 1 hour

572/22= 26 miles per hour

Answer: 26 miles

We know that Baranga drove 572 miles in 22 hours. To find how much she drove every hour, we must divide.

Let m represent miles, and h represent hours.

m ÷ h = 26

Remember to always check your answer.

26 x h = m

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 600 cubic centimeters (cc) when the pressure is 300 millimeters of mercury (mm hg) , find the volume when the pressure is 400 mm hg

Answers

Answer:

V₂ = 450 cm³

Step-by-step explanation:

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P.

[tex]V\propto \dfrac{1}{P}[/tex]

If V₁ = 600 cm³, P₁ = 300 mm hg, P₂ = 400 mm hg

We need to find a new volume. Using the above concept,

[tex]V_1P_1=V_2P_2\\\\V_2=\dfrac{V_1P_1}{P_2}\\\\V_2=\dfrac{600\times 300}{400}\\\\V_2=450\ cm^3[/tex]

So, when the pressure is 400 mm hg, its volume is 450 cubic centimeters

Step-by-step explanation:

The angles pairs and the transversal connecting them are:

a. <1 and <5: transversal r.

b. <7 and <14: transversal q

c. <8 and <11: transversal s

<6 and <15: transversal q.

<3 and <9: transversal p.

Note the following about what a transversal is:

A transversal is a line that intercepts or cut-across two straight lines.

A transversal will connect two angles that lie in two other straight lines the transversal intercepts.

The two angles connected by a transversal can lie on opposite sides of a transversal or on same side along the transversal.

Let's determine the transversal connecting the following given angles:

<1 and <5, is connected by transversal r.

<7 and <14 is connected by transversal q

<8 and <11 is connected by transversal s

<6 and <15 is connected by transversal q

<3 and <9 is connected by transversal p

Therefore, the answers are:
