Answer:

Step-by-step explanation:

18 ∠CBJ ≅ ∠FHG    {AC // HD , BG is transversal. Corresponding angles are equal}

19) ∠FJH ≅ ∠ BJA   {Vertically opposite angles are equal}

20)  m∠EFD = 75°

m∠JAB = m∠ EFD { AC // HD , AE is transversal. Corresponding angles are equal}

m∠JAB = 75°

21) m∠GHF = 130

m∠ JBC =m∠ GHF    {Corresponding angles}

m∠JBC = 130

Answer:

10.717 ounces per second

Step-by-step explanation:

To simplify this, first change the gallons to ounces. 5 gallons is 643 ounces. This means that there are 643 ounces per minute. To find the number of ounces per second, divide 643 by 60 (a minute) =10.7167. The prompt says to round to the nearest hundredth, so 10.717

Answer:

750 meters per minute

Step-by-step explanation:

kilometer = 1000 meters

hour = 60 minutes

(45 x 1000)/60 = 750

Answer:

x=15/2

Hope it helps :)

Answer:

x = 7.5

Step-by-step explanation:

4 = 2/3 (2x - 9)

4 = 4/3x - 6

4 + 6 = 4/3x - 6 + 6

10 = 4/3x

10 x 3/4 = x

x = 7.5

The true equation is 10^6 = 10,000 × 100

The expressions are expressed to the power of 10 :

10^4 = 10 × 10 × 10 × 10 = 10000

10^5 = 10 × 10 × 10 × 10 × 10 = 100,000

10^6 = 10 × 10 × 10 × 10 × 10 × 10 = 10,000 × 100 = 1,000,000 (total of 6 zeros)

10^7 = 10 × 10 × 10 × 10 × 10 × 10 × 10 = 10,000,000

Hence, the only true equation is 10,000 × 100

The length of one side of the basin is 4.49 feet

The basin is cubed shaped.

A cube a three-dimensional shape that is made up of three equal square.

Volume of a cube = a³

Where a is the side length

From the volume of a cube given, the length of the side can be determined by taking the square root of the volume of the cube

side length = ∛volume

The volume is 91.125 cubic feet

∛91.125 = 4.49 feet

In order to determine the side length of a cube given the volume, determine the value of the cube root of the volume.

Answer:

40,960

Step-by-step explanation:

To find the multiplier, set up an equation like this:

[tex]5x=-10[/tex]

The above equation will allow us to find what number, when multiplied with 5 will result in -10. If we divide both sides of the equation by 5, we'll find that the number, x, is -2:

[tex]x=-2[/tex]

We need to find the 14th term. To do this, simply multiply the lattermost number in the sequence by our multiplier, -2.

[tex]20*(-2)=40[/tex]

Since 5 is the first term in the sequence, -10 is the second term in the sequence, and 20 is the third term in the sequence, 40 is the fourth term. Now we just need to find the next ten so that we can find the 14th term. To do that, repeat the process of multiplying the lattermost number by -2 ten more times:

[tex]40*-2=-80\\-80*-2=160\\160*-2=-320\\-320*-2=640\\640*-2=-1280\\-1280*-2=2560\\2560*-2=-5120\\-5120*-2=10240\\10240*-2=-20480\\-20480*-2=40960[/tex]

Therefore, the 14th term is 40,960.

Answer:

4. EF

5. D, E, F

Step-by-step explanation:

4.

Since we want endpoint as E, our first letter in naming the line will be E. Now since we also want it to pass through point F, we can call the line, Line EF or just EF.

5.

Since the definition of collinear is "on the same line" then the only 3 points on the same line in the diagram would be points D, E, and F.

En el circo, para alimentar 3 tigres se necesitan 40 kg de carne por día, entonces para alimentar 6, 9 y 12 tigres se necesitan 80, 120 y 160 kg de carne por día, respectivamente.                      

Para calcular cuántos kg de carne se necesitan para alimentar 6, 9 y 12 tigres, podemos realizar la siguiente conversión (aplicación de regla de 3):

[tex] x = \frac{40 kg}{3 \: tigres}*6\: tigres = 80 kg [/tex]

[tex] x = \frac{40 kg}{3 \: tigres}*9\: tigres = 120 kg [/tex]

[tex] x = \frac{40 kg}{3 \: tigres}*12\: tigres = 160 kg [/tex]

Por lo tanto, se necesitan 80, 120 y 160 kg de carne para alimentar 6, 9 y 12 tigres, respectivamente.
