Answer and explanation:

1. 9:12 or [tex]\frac{9}{12}[/tex] or 9 to 12

It has 9 first because there are 9 lions and then 12 after because there are 12 elephants.

2. 8:16 or [tex]\frac{8}{16}[/tex] or 8 to 16

It has 8 first because there are 8 giraffes and then 16 after because there are 16 otters.

3. 9:10 or [tex]\frac{9}{10}[/tex] or 9 to 10

It has 9 first because there are 9 lions and then 10 after because there are 10 seals.

4. 10:12 or [tex]\frac{10}{12}[/tex] or 10 to 12

It has 10 first because there are 10 seals and then 12 after because there are 12 elephants.

5. 12:9 or [tex]\frac{12}{9}[/tex] or 12 to 9

It has 12 first because there are 10 elephants and then 9 after because there are 9 lions.

6. [tex]\frac{8}{6}[/tex] or [tex]\frac{40}{30}[/tex] or [tex]\frac{16}{12}[/tex]

I just multiplied it first the first one by 2, second one by 10, and 3rd one by 4.

7. [tex]\frac{6}{7}[/tex] or [tex]\frac{42}{49}[/tex] or [tex]\frac{60}{70}[/tex]

I just simplified it first, then I multiplied the simplified one by 6 for the second one, and for the 3rd one I multiplied the simplified by 10.

8. [tex]\frac{2}{3}[/tex] or [tex]\frac{4}{6}[/tex] or [tex]\frac{20}{30}[/tex]

I just simplified it first, then I multiplied the simplified one by 2 for the second one, and for the 3rd one I multiplied the simplified by 10.

9. 3:4 is equivalent to 6:8, 30:40, 12:16

I multiplied it first by 2, then by 10, then by 4.

10. 5:7 is equivalent to 10:14, 50:70, 25:35

I multiplied it first by 2, then by 10, then by 5.

11. 9:2 is equivalent to 18:4, 90:20, 27:6

I multiplied it first by 2, then by 10, then by 3.

12.

a. 48

So first, the ratio we know is 5:4 which in other words is 5x:4x. We also know that there are 60 clownfish. So that means 5x = 60 --> x = 12. So then 4x has to equals 12 x 4 which is 48.

b. 36

So first, the ratio we know is 4:3 which in other words is 4x:3x. We also know that there are 48 angelfish. So that means 4x = 48 --> x = 12. So then 3x has to equals 12 x 3 which is 36.

Answer:

m∠K = 43°

Step-by-step explanation:

By the properties of a parallelogram,

1). Opposite sides of a parallelogram are equal and parallel.

   (6y - 13) = 32 - 3y

   6y + 3y = 32 - 13

   9y = 45

   y = 5

2). Consecutive interior angles are supplementary.

   m∠M + m∠J = 180°

   (6x + 17) + (2x + 3) = 180°

   8x + 20 = 180°

    8x = 160°

    x = 20

    m∠M = (2x + 3)°

              = 2(20) + 3

              = 43°

3). Opposite angles of a parallelogram are equal in measure.

   m∠M = m∠K = 43°

Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. Consecutive angles in a parallelogram are supplementary. The value of x is 20, the value of the y is 5 and value of the angle K is 43 degrees.

Length of the  line XL is 2y+23.

Length of the  line Ml  is 32-3y.

Length of the  line JK is 6y-13.

Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. Consecutive angles in a parallelogram are supplementary.

As the sum of the consecutive angles is equal to the 180 degrees (supplementary). Thus,

[tex]\angle J+\angle M=180\\ 6x+17+2x+3=180\\ 8x+20=180\\ x=\dfrac{180-20}{8}\\ x=20[/tex]

Thus the value of x is 20.

As the the opposite sides of the parallelogram are equal. Thus,

[tex]\begin{aligned}\\ ML&=JK\\ 32-3y&=6y-13\\ 6y+3y&=32+13\\ 9y&=45\\ y&=\dfrac{45}{9} \\ y&=5\\ \end[/tex]

Thus the value of the y is 5.

Opposite angle are equal thus,

[tex]\angle K=\angle M\\ \angle K=2x+3\\ \angle K=2\times20+3\\ \angle K=43[/tex]

Thus the value of x is 20, the value of the y is 5 and value of the angle K is 43 degrees.

4.121216129m

Step-by-step explanation:

use sohcahtoa

tan(70) x 1.5m = 4.121216129m

The height of the tree is 4.12 m.

Given,

I put a ladder 1.5m away from a tree.

The ladder is inclined at 70 degrees about the horizontal.

We need to find out what is the height of the tree.

It is given by:

Tan Ф = Perpendicular / Base

Draw a figure of the given statement.

                       /   | A

                  /        |

(ladder) /             | (tree)

         /.                |

     /.                    |

C /_70°_______ | B  

<--------1.5m-------->              

Find the AB.

AB = height of the tree.

TanФ = AB / CB

Tan 70° = AB / 1.5m

2.7474 = AB / 1.5m

AB = 2.7474 x 1.5m

AB = 4.12 m

Thus the height of the tree is 4.12 m.

r = -189

Step-by-step explanation:

multiply both sides by 9 to get rid of the fraction.

-117=r+72

now subtract 72 from both sides.

-117-72=r

r = -189

Answer:

840 minutes

Step-by-step explanation:

We solve this question using the LCM Method

Find and list multiples of each number of minutes which is given in the quest as 140, 210 and 280 minutes until the first common multiple is found. This is the lowest common multiple.

Multiples of 140:

140, 280, 420, 560, 700, 840, 980, 1120

Multiples of 210:

210, 420, 630, 840, 1050, 1260

Multiples of 280:

280, 560, 840, 1120, 1400

Therefore,

LCM(140, 210, 280) = 840

Therefore, they would have to wait after their first break together to get together again after 840 minutes
