Answer:

18 inches

Step-by-step explanation:

volume of a cuboid = length x breadth x height

the following equation can be derived from the question

let h = unknown height

1/3(24 x 15 x h) = (12 x 18 x 10)

Multiply both sides of the equation by 3

(24 x 15 x h) = (12 x 18 x 10) x 3

Divide both sides of the equation by (24 x 15)

h = 18 inches

Answer:

TQ=SR [since it is isosceles trapezoid]

6x+1.2=9x-48

48+1.2=9x-6x

3x=49.2

x=49.2/3=16.4

now

QR=3×16.4+2.5=51.7

SR=9×16.4-48=99.6

ST=4×16.4-2=63.6

TQ=6×16.4+1.2=99.6

As it's isosceles trapezoid

Now

QR=3(2)+2.5=8.5

RS=9(2)-4.8=13.2

ST=4(2)-2=6

QT=6(2)-1.2=10.8

When you have an irregular figure, you can divide it so that it becomes multiple normal figures. You already did this in the picture, now you just have to find the area of each shape and then add them all together.

From bottom to top:

A=1/2 (b1+b2)h

A= 1/2 (4+2.24)(2)

A= 6.24

(you have two of these on either side)

A=bh

A=6(4)

A=24

A=1/2 bh

A= 1/2 (4)(4)

A=8

(NOTE: there is an error in your drawing. The height of the triangle cant be determined because the 10 value spans over the entire figure when the wings of the rocket are 4 units long and then the body is 6 units long, making it equal 10 already. I'm assuming that the 10 is supposed to go from the bottom of the rectangle to the top of the triangle)

Total figure= 6.24 + 6.24 + 24 + 8

total figure = 44.48

Answer:

F=2x^2+24

Step-by-step explanation:

F=2x^2+18+6

F=2x^2+24

Step-by-step explanation: If the scale factor of a dilation is between 0 and 1, the image will be smaller than the object, a reduction. It would only be an enlargement if the scale factor is greater than 1.

Answer:

b ≈ 8.49

Step-by-step explanation:

A^2 + b^2 = c^2.   (Pythagorean theorem)

c is the hypotenuse or the longest side of a triangle.

a and b are the other 2 sides.

17^2 + b^2 = 19^2

289 + b^2 = 361

289 + b^2 - 289 = 361 - 289

b^2 = 72

b ≈ 8.49

Have a great day!

Given:

w be the weight in pounds of a baby tigers.

To find:

The inequality if baby tigers can be no larger than 4 pounds.

Solution:

Baby tigers can be no larger than 4 pounds. It mean weight of baby tigers cannot be greater than 4. In other words, the weight of the baby tigers must be less than or equal to 4.

Let w represents weight in pounds and the weight of the baby tigers must be less than or equal to 4. So,

[tex]w\leq 4[/tex]

Therefore, the required inequality is [tex]w\leq 4[/tex].

Answer:

m<3 = 108

Step-by-step explanation:

Since <1 and <2 are supplementary, the equation is:

<1 + <2 = 180

Since <1 and <3 are vertical angles. the equation is:

<1 = <3

To find m<3:

<2 + <3 = 180

72 + <3 = 180

<3 = 180 - 72

<3 = 108

The measure of angle ∠3 is 108 degrees.

Supplementary angles are those angles that sum up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

For the given situation,

∠1 and ∠2 are supplementary angles.

∠1 and ∠3 are vertical angles.

Measure of angle, m ∠2 = 72

From definition, we know that

∠1 + ∠2 = 180 (supplementary angles) ------- (1)

and

∠1 = ∠3 (vertical angles) --------- (2)

From (1) and (2),

⇒ [tex]\angle3 + \angle2 = 180[/tex]

⇒ [tex]\angle3=180-72[/tex]

⇒ [tex]\angle3=108[/tex]

Hence we can conclude that the measure of angle ∠3 is 108 degrees.

Answer:

79 minutes

Step-by-step explanation:

A plane is travelling at 180 meters per seconds

Convert to km/hr

180× 18/5

= 648 km/hr

Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is

= 1/648 × 800

= 1 hour 19 minutes

Conver the time to full minutes

60 minutes = 1 hour

= 60+19

= 79 minutes

Hence the minutes required for the plane to travel 800km is 79 minutes

Answer:

El porcentaje de descuento fue del 10%.

Step-by-step explanation:

Para encontrar el porcentaje de descuento, puedes calcular la variación entre los dos precios ya que este será el porcentaje aplicado. Para hacerlo debes calcular la diferencia entre los dos precios restando el precio final menos el precio original y luego, debes dividir este resultado entre el precio original y multiplicar por 100:

Precio original=50

Precio final=45

((45-50)/50)*100

(-5/50)*100=-0.1*100=-10%

De acuerdo a esto, la respuesta es que el porcentaje de descuento fue del 10%.

Step-by-step explanation:

Given:

Expression

2 - 50x²

Find:

Factorization of the given expression

Computation:

2 - 50x²

By taking 2 as common

⇒ a² - b² = (a + b)(a - b)

In given expression;

⇒ a = 1

⇒ b = 5x

⇒ 2[(1)² - (5x)²]

2[(1 + 5x) (1 - 5x)]
