Which unit rate is equivalent to 15 miles per gallon?
thirty miles over three gallons
three gallons over thirty miles
four gallons over sixty miles
sixty miles over four gallons

Fourth option is correct.

Step-by-step explanation:

Since we have given that

thirty miles over three gallons  

Unit rate would be miles per gallon.

three gallons over thirty miles  

Unit rate would be miles per gallon.

four gallons over sixty miles  

Unit rate would be miles per gallon.

sixty miles over four gallons

Unit rate would be miles per gallon.

Hence, Fourth option is correct.

ok

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.
