Answer 1

Answer:

A. 442.05

Step-by-step explanation:

✔️First find the radius of circle J:

θ = 43°

Acr length = 52.8

Thus,

Acr length = θ/360*2πr

Plug in the values

52.8 = 43/360*2*π*r

52.8 = 0.751r

Divide both sides by 0.75

52.8/0.75 = r

r = 70.4 (nearest hundredth)

✔️Find the Circumference of circle J:

Circumference = 2πr

Radius (r) of circle J = 70.4

Plug in the values

Circumference = 2*π*70.4

= 442.34

This is close to the answer in option A. Therefore, the answer is 442.05.

In the equation of a straight line, y = mx + c. what does the 'c' represents

Answers

Answer:

Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).

Find an equation for the perpendicular bisector of the line segment whose end points are (-9,-8) and (3,-2)

Answers

Answer:

[tex]y=-2x-11[/tex]

Step-by-step explanation:

Slope of the line segment = [(-8)-(-2)]/[(-9)-3]=-6/-12=1/2

Slope of the perpendicular bisector x slope of line segment = -1

Slope of perpendicular bisector = -2

Mid-point of line segment = ((-9+3)/2, (-8+(-2))/2) = (-3, -5)

The perpendicular bisector passes through the mid-point.

By point-slope form,

[tex]\frac{y-(-5)}{x-(-3)} = -2\\y+5=-2x-6\\y=-2x-11[/tex]

Ivan has 6 times as many blue beads as red beads. he has 49 red and blue beads in all. how many blue beads does Ivan have

Answers

Answer:

Ivan has 42 blue beads.

Step-by-step explanation:

We need to find how many blue beads Ivan has.

Blue beads = 6 times as many as red beans

b = 6r

r + b = 49

r + (6r) = 49

7r = 49

Divide both sides by seven to isolate r

r = 7

b = 6(7)

b = 42
