Zoey's dog has a water bowl with a diameter of 6 inches. Sam's
dog has a water bowl with a diameter of 10 inches. What is the
approximate difference in the circumference (distance around)
ut of the two water bowls?

Answers

Answer:

12.56 inches

Step-by-step explanation:

Circumference: C = 2*pi*r

I will be using 3.14 in place of pi

Divide the diameters by 2, so 3 for Zoey and 5 for Sam

Multiply (2*3.14*3) and (2*3.14*5)

For Zoey you get 18.84 and for Sam you get 31.4

31.4-18.84= 12.56 in difference

Find the measure of each missing angle. ​Subject: Geometry
Unit 5: Relationships in Triangles
Homework 1: Triangle Midsegments

Answers

Answer:

Q10

∠1 = ∠5 = 180° - 144° = 36°∠2 = 56°∠3 = 180° - 56° = 124°∠4 = 144° - 56° = 88°∠5 = ∠1 = 36°

Q11

∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°

Measure of angles for figure 1:

∠1=36∠2=56∠3=124∠4=88∠5=36

Measure of angles for figure 2:

∠1=35∠2=145∠3=55∠4=125∠5=55

The angle is formed by two rays at a common point of the two rays.

For given figure 1:

∠1+144=180 (Sum of angles on same side of transversal is 180°)

∠1=180-144

∠1=36

∠5+144=180(Sum of angles on a line is 180°)

∠5=180-144

∠5=36

Similarly, ∠3=180-56

∠3=124

∠4+36+56=180(Sum of all angles of a triangle is 180°)

∠4=180-36-56

∠4=88

∠2+36+88=180

∠2=56

Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.

For given, figure 2:

∠1=35(Alternate angle on same side of transversal are equal)

∠2=180-35

∠5=180-35-90(Sum of all angles of a triangle is 180°)

∠5=55

∠4+55=180(Sum of angles on a line is 180°)

∠4=180-55

∠4=125

Similarly, ∠2=180-35(Sum of angles on a line is 180°)

∠2=145

∠3=180-35-90(Sum of all angles of a triangle is 180°)

∠3=55

Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55

9y-8x=63 How do I convert this into slope-intercept form?​

Answers

Answer:

turn it into y=mx+b

Step-by-step explanation:

get y alone

add 8x to both sides

9y=63+8x

divide both sides by 9

63/9=7 8x/9= [tex]\frac{8x}{9}[/tex]

simplify

y=[tex]\frac{8}{9}[/tex]x+7

Answer:

y = 0.8x + 7      or

y = [tex]\frac{4}{5}[/tex]x + 7

Step-by-step explanation:

The slope intercept formula is: y = mx + b

9y - 8x = 63

    +8x    +8x

=  9y = 63 + 8x

    9y/9 = 63/9 + 8x/9    ←                                                                                  

We're getting rid of the 9 beside the y, so we have to divde every number by 9.

=     y = 0.8x + 7     if you want the 0.8 as a fraction, it'll be [tex]\frac{4}{5}[/tex]

Answer:

y=-2x+7

Step-by-step explanation:

slope intercept form is equal to y=mx+c

where y is the y value

x is the x value

m is the gradient

and c is the y intercept

so the equation for this set of values is equal to

y=-2x+7

slope will be the m

and b is the y intercept

y＝mx＋b
