Answer:

You calculate the distance between the angle and the arch and you can solve your answer.

Step-by-step explanation:

For example... An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees, and we can easily convert between each with the formula π radians = 180° π r a d I a n s = 180 ° .

Write the equation of a line, in general form, that has an slope of zero and a y-intercept of (0,4).
vaieri [72.5K]

Answer:

y - 4 = 0

Step-by-step explanation:

They give you the y coordinate, 4, and the x coordinate as 0.

Put 4 in as y.

4 - 4 = 0. That means x = 0 and that is right.

To make sure it has a slope of zero, subtract 4 on both sides.

You get : y = 4. This means that the line will be straight and it will have a slope of zero.

The cost (in dollars) of making b bracelets is represented by 4 5b. The cost (in dollars) of making b necklaces is represented b
Leviafan [203]

Answer:

$(3b+2)

Step-by-step explanation:

The cost of making b bracelets = 4+5b

The cost  of making b necklaces = 8b+6.

To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.

Extra Cost = Cost of b Necklaces-Cost of b Bracelets

=(8b+6)-(4+5b)

open the brackets

=8b+6-4-5b

Collect like terms

=8b-5b+6-4

=3b+2

It costs $(3b+2) more to make b necklaces than b bracelets.
