TEACHER DIDN'T TEACH IT AND I HAVE NO CLUE HOW TO DO THESE PROBLEMS.....1.A BUS TRAVELED FOR 2H @ R MI/H, THEN DECREASED THE SPEED BY 10 MI/H AND TRAVELED FOR 1 MORE HOUR. HOW FAR DID THE BUST GO?
2.AN ANGLE HAS MEASURE X TO THE 0 POWER. FIND THE AVERAGE OF THE MEASURES OF A COMPLEMENT AND A SUPPLEMENT OF THE ANGLE.
US V=1/3BH
3. A PYRAMID HAS A RECTANGULAR BASE. FIND THE VOLUME IF THE LENGH AND WIDTH OF THE BASE AND THE HEIGHT ARE 3 CONSECUTIVE ODD INTEGERS AND X IS THE LARGEST INTEGER.
4. JORGE BOUGHT S 40 CENT STAMPS AND TREE TIMES AS MAY 25 CENT STAMPS. HOW MANY DOLLARS DID HE SPEND?
5. THE LENGTH OF A RECTANGULAR FIELD IS 45FT GREATER THAN ITS WIDTH, W FT. HOW MUCH FENCING IS NEEDED TO ENCLOSE THE FIELD AND DIVIDE IT INTO PARTS?

1. The bus traveled 2*R miles in the first 2 hours, and
1*(R-10) miles the third hour, so the bus traveled 2*R + R - 10 = 3*R - 10 miles.
2. x^0 = 1. (I assume you are using degree measure.) Then the complemen is 90 - 1 = 89 degrees, and the supplement = 180 - 1 = 179.
3. Hint: the three consecutive odd integers are x - 4, x - 2, and x.
4. 40*S + 25*(3S) cents. Now convert to dollars.
5. You should see what's going on by now.
