This is about division of fractions.

Option C; 7 and one half

When Dividing fractions, we change the sign to multiplication sign and the make the get the reciprocal of the divisor i.e. the divisor's numerator to be the denominator and the denominator to be the numerator. Thereafter we multiply by the dividend.

Thus;

3 ÷ 2/5 = 3 × 5/2

>> 15/2

>> 7½

Thus, looking at the options, the only one that corresponds with our answer of 7½ is option C.

So, option C is the correct answer.

Step-by-step explanation:

The sum of the first n odd numbers is n^2

This can be proven, but for 5 odd numbers, 1,3,5,7,9, the sum should be 5^2, or 25, which it is

So for the first 44 odd numbers, the sum is n^2=44^2=1936

Slope problem im pretty sure it is -1/3 correct me if im wrong

Answers

Answer:
The answer is -3.

Explanation:
The slope of a line is the ratio of how many units the line moves up or down the y axis to how many units the line moves across the x axis. In other words, it’s the rise/run of a line.

In the graph in the attached picture, every time the x axis increases by one, the y axis decreases by 3. Therefore, the ratio would be -3/1.

-3/1 is equal to -3, making the slope of this line -3.

10 POINTS PLEASE HELP ASAP!!! What is the length of the altitude of the equilateral triangle below?

Answers

Step-by-step explanation:

Hey there!

Looking on figure we find that triangle ABC is a Right angled triangle.

Taking reference angle as C, we get;

Perpendicular (p) = a

Base(b) = 5

And hypotenuse (h)= 10

Now;

Using Pythagoras relation, we get;

[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]

Put all values.

[tex]a = \sqrt{ {10}^{2} - {5}^{2} } [/tex]

[tex]a = \sqrt{100 - 25} [/tex]

[tex]a = \sqrt{75} [/tex]

[tex]a = 5 \sqrt{3} [/tex]

Therefore, answer is Option E.

Find the square root of the
following numbers by prime factorisation method :
(iii) 3136​

Answers

3136 = 1568 x 2
1568 = 784 x 2
784 = 392 x 2
392 = 196 x 2
196 = 98 x 2
98 = 49 x 2
So 49 x 2 x 2 x 2 x 2 x 2 x 2 = 49 x 4 x 4 x 4 = 3136
So the square root of 3136 = the square root of (49 x 4 x 4 x 4) = 7 x 2 x 2 x 2 = 56
