Answer:

(x+6) (x+6)

(x+6)^2

Step-by-step explanation:

36+12x+x^2

x^2 +12x +36

What 2 numbers multiply to 36 and add to 12

6*6 = 36

6+6 =12

(x+6) (x+6)

(x+6)^2

g Two different factories named A and B both produce an automobile part. If a part came from A, the probability that the part is

Fed [463]

Answer:

0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.

Step-by-step explanation:

Probability of a defective part:

0.04 of $\frac{100}{180}$ , that is, coming from A.

0.05 of $\frac{80}{180}$ , that is, coming from B. So

$p = 0.04\frac{100}{180} + 0.05\frac{80}{180} = \frac{0.04*100 + 0.05*80}{180} = 0.0444$

0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.

Pls help due tomorrow just numbers 7 - 12

Luden [163]

Answer:

Step-by-step explanation:

7). 5.75% = $\frac{5.75}{100}$ = $\frac{575}{10000}$ = $\frac{23}{400}$

10). $16\frac{2}{3}$ % = $\frac{50}{3}$ % = $\frac{50}{300}$ = $\frac{1}{6}$

12). $79\frac{5}{6}$ % = $\frac{479}{6}$ % = $\frac{479}{600}$

Now is you turn. You can do it!

Does anyone know how to solve this?

Bezzdna [24]

Use this version of the Law of Cosines to find side b:

b^2 = a^2 + c^2 − 2ac cos(B)

We want side b.

b^2 = (41)^2 + (20)^2 - 2(41)(20)cos(36°)

After finding b, you can use the Law of Sines to find angles A and C or use other forms of the Law of Cosines to find angles A and C.

Try it....

Where are white blue and red boat in the Marina three fourths of the boats in the Marina are white for seventh of the remaining

xeze [42]

Answer:

Step-by-step explanation:

Here is the complete question used in answering this question :

Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?

We first have to determine the fraction of the boats that are red

1 - ( $\frac{3}{4}$ + $\frac{4}{7}$ )

1 - $\frac{21 + 16}{28}$

1 - $\frac{37}{28}$

1 - 1 $\frac{9}{28}$

= 9/28

so, 9/28 of the boats are red

let b represent the total number of boats

9/28 x b = 9

to find b, divide both sides of the equation by 28/9

b = 28
