1. A car bought for $20,000. Its value depreciates by 10% each year for 3 years. What is the car's worth after3 years? 2. Find the perimeter of a circle whose radius is 3.5cm. (Take pi = 22/7) 3. The volume of a cone is 1540cm³. If its radius is 7cm, calculate the height of the cone. (Take pi = 22/7) 4. What is the coefficient of b in the expression b² - 5b +18 5. Expand (x +2) (9 - x) 7. Find x and y in the simultaneous equations. x + y = 4 3x + y = 8 8. Factorize a² +3ab - 5ab - 15b² 9. The bearing of a staff room from the assembly ground is 195degrees, what is the bearing of the assembly ground from the staff room?

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
