Divide 132kg in a ratio of 3:3:5

Answers

Answer 1
Answer: 3 + 3 + 5 = 11 (11 total parts of the ratio.)

132 ÷ 11 = 12 (one part of the ratio)

Multiply 12 by the number of parts in the ratio:

12 × 3 = 36
12 × 3 = 36
12 × 5 = 60

Therefore, the final answer is 36:36:60 kg. 
Answer 2
Answer: Let the common multiple be x

So, according to the ratio, we will have parts as

3x
3x
5x

Here, they add up to 132

Writing equation.
132 = 3x + 3x + 5x
132 = 11x
x = 12

Now, putting the values !!

3x = 3 × 12 = 36 kg
3x = 3 × 12 = 36 kg
5x = 5 × 12 = 60 kg

(x+2) is one of the factors of the polynomial x³+13x²+32x+20. Find its remaining factors.A little help....​

Answers

Answer:

x^2+11x+10

or

(x+1)(x+10) since you can factor x^2+11x+10

Step-by-step explanation:

Let's do synthetic division.

We are dividing by x+2, so -2 will be on the outside. Like this:

-2 |         1          13          32         20

   |                     -2        -22         -20

   |___________________________

             1          11           10            0

The remainder is 0, so (x+2) is indeed a factor of x^3+13x^2+32x+20.

The other factor we found by doing this is (x^2+11x+10).

You can find more factors by factoring x^2+11x+10.

Two numbers that multiply to be 10 and add to be 11 is 10 and 1 so the factored form of x^2+11x+10 is (x+10)(x+1).

Answers

Answer:

A. x = 2

E. x = -5

Step-by-step explanation:

Step 1: GCF

2(x² + 3x) = 20

x² + 3x = 10

Step 2: Complete the Square

x² + 3x + 9/4 = 10 + 9/4

(x + 3/2)² = 49/4

Step 3: Solve

√(x + 3/2)² = √49/4

x + 3/2 = ±7/2

x = -3/2±7/2 or x = -5, 2

Barbara claims that her horse can do simple addition problems. She showed her horse 8 different cards with simple addition problems, and the horse was able to tap his foot to indicate whether the answer was correct or incorrect. The horse correctly identified all 8 cards. Eric didn't believe Barbara's horse could do addition, so he set up a trial to test whether the horse was just guessing. He flipped 8 coins to see how many would land tails up. He did this 53 times, and the results are shown in the dot plot below:
