How you could use paper folding to construct the bisector of an angle

1 answer:

8 0

<span>This really works well with wax paper. It is transparent and it leaves a visible white line on the crease. For the perpendicular bisector of a line segment, fold the endpoints of the line segment onto each other. The crease is the perpendicular bisector. This of course also gives you the midpoint, because that is where the perpendicular bisector intersects the line segment. For an angle bisector, put the crease through the vertex of the angle and lay the sides of the angle over top of each other. The crease is the angle bisecto

What is the simplified Expression of -2/3(12c-9)+14c

Stells [14]

Answer:

=6(1 + c)

Step-by-step explanation:

Given that:

= -2/3(12c-9)+14c

By simplifying:

Negative sign before bracket will alter the inner signs

=-24c/3 + 18/3 +14c

= -8c + 6 + 14c

= 6 + 6c

By taking 6 common:

=6(1 + c)

I hope it will help you!

Each shelf holds 5 hermit-crab cages and 3 hermit-crab care booklets. If there are 23 hermit crab cages and 12 booklets to displ

Harrizon [31]

1. Each shelf holds 5 hermit-crab cages. There are 23 hermit crab cages to be displayed. Divide the number of hermit crab cages to be displayed by the number of hermit crab cages that can be displayed on each shelf:

$23=5\cdot 4+3.$

This means that you need 5 shelves (4 shelves is not enough, because 3 hermit crab cages will be not displayed).

2. Each shelf holds 3 hermit-crab care booklets. There are 12 hermit-crab care booklets to be displayed. Divide the number of hermit-crab care booklets to be displayed by the number of hermit-crab care booklets that can be displayed on each shelf:

$12=3\cdot 4.$

This means that you need 4 shelves.

Answer: first, you have to divide 23 by 5 and find the quotient and remainder and divide 12 by 3 and find the quotient and remainder. Then you have to determine the number of shelves needed. You need 5 shelves.

What is .40 = .25 X

leva [86]

Answer:

x=1.6

Step-by-step explanation:

.40=.25x

you move .25 to the other side which would look like this .40/.25=x and then you solve for x, which you would get 1.6.
