23 is the answer

Explanation:
6-(-2)= 8 because negative and negative becomes positive so we add them.
-3(-5) = 15 because we have to multiply -3 by -5 which is 15 because when we multiply 2 negative numbers we get a positive
Now:
15 + 8 = 23

Mrs Atkins is going to choose two students from her class to take part in a competition.
Schach [20]

Given:

Total number of girls in her class = 16

Total number of boys in her class = 14

To find:

The number of different ways of choosing one girl and one boy.

Solution:

We have,

Total number of girls = 16

Total number of boys = 14

So,

Total number of ways to select one girl from 16 girls = 16

Total number of ways to select one boy from 14 boys = 14

Now, number of different ways of choosing one girl and one boy is

16\times 14=224

Therefore, the required number of different ways is 224.

The triangles shown have the same perimeter. What is the value of x?
olga nikolaevna [1]

Answer:

18

Step-by-step explanation:

Since you know the perimeters are equal, write your equation.

x+6 + x+6 + x+6 = x + x+6 + 2x-6

combine like terms

3x + 18 = 4x

isolate your x by subtracting 3x from each side

18 = x

check your answer:

3x + 18 = 72

4x = 72

What is the sum of the lengths, in centimeters, of the two legs of a 30-60-90 right triangle, if the length of the hypotenuse is
Nesterboy [21]

The sum of the lengths of two legs of the 30°-60°-90° right triangle is 6.69 centimeters. Using the ratio of sides for the 30°-60°-90° triangle, the sum is calculated.

<h3>What is the ratio of sides for the 30°-60°-90° triangle?</h3>

The ratio for the 30°-60°-90° triangle is 1:√3:2 or x:x√3:2x

where x corresponds to the length opposite the 30° angle and x√3 is opposite of the 60° angle and 2x is opposite to the 90° angle.

<h3 /><h3>Calculation:</h3>

It is given that the triangle is a right triangle with angles 30°-60°-90°

For such a triangle, the ratio of side lengths is x: x\sqrt{3}:2x

we have the length of the hypotenuse is 2\sqrt{6}

So, 2x = 2\sqrt{6}

⇒ x = \sqrt{6}

So,

the other length of the other leg is x√3 = √6 × √3 = 3 √2

Then, the sum of these two legs = √6 + 3√2 = 6.69 centimeters.
