Answer:

Step-by-step explanation:

The one with the line that has a steep positive slope. (The slope is the x-coefficient, 3.5. This means the line goes up 3.5 units for each unit it goes to the right.)

What is the sum of the

Dahasolnce [82]

Answer:

360 degree

Step-by-step explanation:

The sum of all the exterior angles is 360 for any polygon.

This can be proved for polygon with 20 sides also.

We know that sum of all the angles of polygon is given by formula = (2*n -4) *90

where n is the no. of sides of polygon

for 20 sides polygon sum of sum of all the angles = (2*20 -4) * 90

= (40-4)*90 = 36*90 = 3240 degree

measure of each angle of polygon = sum of total angles of polygon/ no of sides of polygon = 3240/20 = 162

We also know that sum of interior and exterior angle of triangle is 180 degree, as interior and exterior angle lies on straight line and they are supplementary

162 + value of exterior angle = 180

=> value of exterior angle = 180 - 162 = 18

Value of one exterior angle is 18 degree

in 20 sided polygon there are 20 exterior angle

therefore, value of 20 exterior angle is 18*20 degree which is 360 degree.

__________________________________________________________

As a general point one can memorize than sum of all the exterior angle for a polygon with any number of side is 360.

Y=2/3x-4 and y=-3/2x+1 are perpendicular lines. Jack notices that the product of the two perpendicular slopes is -1. If a line h

lana66690 [7]

Answer:

Slope = -b/a.

Step-by-step explanation:

Note that the relation between 2/3 and -3/2 is that their product is -1.

If the slope is a/b then we have a/b * m = -1 where m is the slope of the perpendicular line .

So m = -1 / a/b

= -b/a.

The produce = a/b * -b/a = -1.

Marguerite is building a box. She needs 78 pieces of wood that are 29 cm long. The wood comes in boards that are 6 meters long.

ser-zykov [4K]

First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:
$78*29cm=2262cm$

Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:
$2262cm* \frac{1m}{100cm} =22.62m$

Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:
$\frac{22.62m}{6m} =3.77$
Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.

We can conclude that Marguerite will need 4 boards of wood.
