Answer:

C. 5

Step-by-step explanation:

Keeping in mind that this is a right triangle, to find the length of side a, we can use the Pythagorean Theorem.

Remember, the Pythagorean Theorem is:

a² + b² = c²

where a and b are the legs of the right triangle and c is the hypotenuse.

As we can see in the image, a is one of the two legs of the right triangle. 13 is the hypotenuse and 12 is another leg. Plugging into the Pythagorean Theorem, we get:

a² + 12² = 13²

Now we solve for a.

a² + 144 = 169

Subtract 144 from both sides.

a² = 169 - 144

a² = 25

Take the square root of both sides.

a = √25

a = 5

So the length of side a would be 5.

The answer would be C. 5.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer: C. 5

Step-by-step explanation:

We'll use the Pythagorean Theorem to find the missing side.

a^2 + b^2 = c^2

a^2 + 12^2 = 13^2

a^2 +  144 = 169

a^2 = 25

(simplify)

[tex]a^2 = \sqrt{25}[/tex]

a = 5

Answer:

the answer is B. 150

Answer:

no it is not a right triangle because the lengths add up to 176 and a right triangle should add up to 190.

Step-by-step explanation:

The side measures of the triangle does not form a right triangle.

A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.

For the given situation,

The side lengths of the triangle are 44 meters, 55 meters, 77 meters.

For the triangle to be a right triangle, one interior angle should be 90°.

Based on the sides, by Pythagoras theorem,

Square of long side = sum of square of other two sides

⇒ [tex]77^{2}=44^{2} +55^{2}[/tex]

⇒ [tex]5929=1936+3025[/tex]

⇒ [tex]5929\neq 4961[/tex]

Hence we can conclude that the side measures of the triangle does not form a right triangle.

Answer:

2:3:5

Step-by-step explanation:

24:36:60

1) Find the greatest common factor

24 ⇒ 1, 2, 3, 4, 6, 8, 12, 24

36 ⇒ 1, 2, 3, 4, 6, 9, 12, 18, 36

60 ⇒ 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Therefore, the greatest common factor is 12.

2) Divide all values by 12

24 ÷ 12 = 2

36 ÷ 12 = 3

60 ÷ 12 = 5

Therefore, the simplified form of the ratio is 2:3:5.

Answer:

The final mean is higher

Step-by-step explanation:

The mean of all the scores = [tex]\frac{90 + 85 + 98 + 60 + 84 + 78}{6\\} = \frac{495}{6} = 82.5\\[/tex]

The mean of the scores with the 60 dropped = [tex]\frac{435}{5} = 87[/tex]

The final mean is higher

That will always happen when you drop the lowest score.  I worked it out for you so that you would see that it happened in your case.

Answer:

The coordinates of point y after the transformation is (-6,5)

Step-by-step explanation:

Firstly , we need to get the coordinates of the point y before the transformation

The coordinates are

(-6,-5)

By reflecting over the y-axis, we have the following change;

(x,y) becomes (-x,y)

So we have;

(6,-5)

Then we are to rotate at an angle of 180 degrees counterclockwise

The operation here will be;

(x,y) to (-x,-y)

So we have;

(6,-5) to (-6,5)

Answer:

52.94%

270 minutes

Step-by-step explanation:

1. 9 plants - 15 minutes

x plants - 75 minutes

Cross multiply

15x = 75 x 9

15x = 675

Divide both sides by 15

x = 675/15

x = 45 plants

45/85 x 100

= 52.94%

2. 90% of 180

= 90/100 x 180

= 162 plants

9 plants - 15 minutes

162 plants - x minutes

Cross multiply

9x = 162 x 15

9x = 2430

Divide both sides by 9

x = 2430/9

x = 270 minutes or 4 hours 30 minutes.

Answer:

a₁ = 37

Step-by-step explanation:

In an arithmetic progression the common difference d is

d = a₂ - a₁ = a₃ - a₂ , that is

2x - 18 - (x + 1) = 2x - 1 - (2x - 18) ← distribute and simplify both sides

2x - 18 - x - 1 = 2x - 1 - 2x + 18

x - 19 = 17 ( add 19 to both sides )

x = 36

Thus

a₁ = x + 1 = 36 + 1 = 37
