Arianna has a large piece of fabric that she wants to use to make some scarves. the number n of scarves she can make is inversely proportional to the area a of each scarf. if the area of each scarf is 4 square feet, then she can make 15 scarves. if the area of each scarf is 5 square feet, how many scarves can she make?

arianna can make blank scarves.

12 Scarves

Step-by-step explanation:

Given.

number of scarves is N

Area of scarves is A

N ∝

-------------(2)

where k is the constant value of the above equation

If area of each scarves is 4 square feet, then she can make 15 scarves.

If area of each scarves is 5 square feet, then how many scarves can she make.

Area of scarves is 5 square feet that means

Put the A, k value in equation 2

Therefore, Arianna can makes 12 scarves.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
