-7y=91
a/9=-4
-1/2m=-9

Answers

Answer 1
1. y= -13
2. a= -36
3. m= -18
Answer 2

Answer:

y = -13

a = -36

m = 18

Step-by-step explanation:

-7y=91

divide both sides by -7

-7y/-7 = 91/-7

y = -13

a/9=-4

multiply both sides by 9

9(a/9) = 9(-4)

a = -36

-1/2m=-9

multiply both sides by 2

2(-1/2m) = 2(-9)

-1m = -18

divide both sides by -1

m = 18

Answer:

144 or 72^2

Step-by-step explanation:

You have one leg a 5 and the other leg we don't know, well we know the hyponuse is a 13.

So the first step is

A^2 + B^2 = C^2

2 step,

5^2 + B^2 = 13^2

3 step

5 x 5 = 25 and 13 x 13 = 169

25 + B^2 = 169

4 step

169 - 25 = 144

144 divided by 2 is 72, so 72 x 72 is 144.

If you have an answer 72 squared or 144 both will work.

It does not help that you don't give the answers.

The answer would be 144. Hope this helps!!!!!

Please help how do you solve this?

Answers

Answer:

A, 120 degrees

Step-by-step explanation:

Answer:  A) 120 degrees

=============================================================

Explanation:

Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.

The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.

Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees

------------

Or another method you could use is the fact that all exterior angles of any polygon add to 360.

Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees

We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.

The interquartile range (IQR) of the data set is:

                                3.5

Step-by-step explanation:

The data points are given as follows:

       0, 1 1/2, 2 1/2, 3, 4, 4, 4, 7, 7 1/2

i.e.   0 , 1.5 , 2.5 , 3 , 4 , 4 , 4  , 7 , 7.5

There are a total of 9 data points and we know that the median of the data is the central tendency of the data and it always exist in the middle of the data.

Here we have 9 data points.

and hence the median exist at the the 5th place.

Hence, Median of data of Middle quartile i.e. = 4

Also, the  lower set of data is:

                 0 , 1.5 , 2.5 , 3

and the first quartile or the lower quartile i.e.  is the median of the lower set of data.

i.e.  

The upper set of data is:

                 4 , 4  , 7 , 7.5

and the third quartile or the upper quartile i.e.  is the median of the upper set of data.
