Given that 5 canadian dollars are worth 4 us dollars and that 9 australian dollars are worth 7 us dollars. How many canadian dollars are there to 1 australian dollar.

1 australian dollar = 0.972 Canadian dollars

Step-by-step explanation:

Given that 5 canadian dollars are worth 4 us dollars, it means that the worth of 1 US dollars would be

5/4 = 1.25 canadian dollars.

Given that 9 australian dollars are worth 7 us dollars, it means the worth of 1 Us dollars would be 9/7 australian dollars.

This means that 1.25 canadian dollars = 9/7 australian dollars.

Therefore,

1 australian dollar would be equal to

1.25 × 7/9 = 0.972 Canadian dollars

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

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.
