Answer: 3 : 5 and 6 : 10

Explanation: First rewrite the ratio 12 : 20 as the fraction 12/20.

Next, we can find an equal ratio by

simply writing this fraction in lowest terms.

If we divide both the numerator and denominator of 12/20

by their greatest common factor of 4, we get the equal ratio 3/5.

Now we can use 3/5 to find another equal ratio.

If we multiply both the numerator and denominator

of 3/5 by 2, we get the equal ratio 6/10.

So 12 : 20 is equal to 3 : 5 and 6 : 10.

Make sure to write your final answers

using the same form as the original problem.

Answer:

2 *( 3+7-9) =(1+5) - ( 8 -4 )

Step-by-step explanation:

2 _( 3_7_9) = (1_ 5) _ ( 8 _4 )

I just started playing with things

2 *( 3+7-9) = (1_5 ) _ ( 8 _4 )

2 * (10-9)

2*1

So the left side is 2

Now to make the right side 2

(1+5) - ( 8 -4 )

6 - 4

2

Find an angle between 0 and 2pi that is coterminal with the following angle.<br><br> 32pi/9
never [62]
<span>To do these you will be adding or subtracting  2pi (or integer multiples of .

Since the given angles are in fraction form, it will help to have 2pi  in fraction form, 2pi=10/5=6pi/3=4pi/2=18pi/9     NOTE: this>(/) stands for over like 1 over 2 EX. 1/2

too, so the addition/subtraction is easier.

Hint: When deciding if you have a number between 0 and 2pi, compare it to the fraction version of 2pi that you've been adding/subtracting.


For 17pi/5...
First we can see that 17pi/5 is more than 10pi/5 (aka 2pi). So we need to start subtracting: 17pi/5 - 10pi/5 = 7pi/5

Now we have a number between 0 and 10pi/5. So 7pi/5 is the co-terminal angle between 0 and 2pi.

I'll leave the others for you to do. Just remember that you might have to add or subtract  multiple times before you get a number between 0 and 2pi.
P.S don't add or subtract at all if the number starts out between 0 and 2pi.</span>

the table shows the cost of the daycare for Lucy's dog this week her dog went 3 full days of day care and 2 half days of day car
drek231 [11]

An expression for the total cost of the daycare for Lucy's dog this week is T = 3F + 2H and the total cost is equal to $114.

<h3>How to write an expression for the total cost?</h3>

In this exercise, you're required to write an expression for the total cost of the daycare for Lucy's dog this week. Thus, we would assign a variable to the cost for full-day and half-day day care as follows:

  • Let the cost for full-day be F.
  • Let the cost for half-day be H.
  • Let total cost be T.

Thus, the total cost of the daycare is given by:

T = 3F + 2H

Evaluating the expression, we have:

T = 3(28) + 2(15)

T = 84 + 30

T = $114.
