##### 10. A soda company is testing a new sized can to put on the market. The new can is 6 inches in diameter and 12 inches in height. What is the volume of the can in cubic inches?
1. 339

4. 226

###### 1.B

The relationship can be expressed as: 15/10 =45/x; 15x = 450; x = 30.

###### 2. C

The total amount of the bill is: 3.70/x =8/100; 370 = 8x; x = \$46.25.

###### 3. B

If E + B = 225, and E = 2B + 5, then 225 – B = 2B + 5. Solving for B, 3B = 220 and B = 73.3. 225 – 73.3 = 151.7.

###### 4. B

Double the number that is added to the previous number. So, 4+2=6, 6+4=10, 10+8=18, 18+16=34, and 34+32=66.

###### 5. D

1 gallon = 128 ounces, so 8 x 128 = 1,024 ounces for 8 gallons. 1/2 = 64 gallons, and 1/4 = 32 gallons, so 64 + 32 = 96 ounces to fill the 3/4 gallons; the total ounces required is 1,024 + 96 = 1,120 ounces.

###### 6. B

If mangoes are represented by x and coconuts are represented by y, then:
x + y = 10, and 2x + 4y = 30
2(10-y) + 4y = 30
20 – 2y + 4y = 30
2y = 10
y = 5 and x = 5, or 5 of each type of fruit

###### 7. B

Given the increasing trend, the data can be extrapolated from 25 to about 31, the closest possible answer.

###### 8. A

Using the Pythagorean theorem: 252 + 352 = c2. 625 + 1225 = c2. c = ?1850 = 43.01.

###### 9. B

20/1 =240/X. 20X = 240. X = 240/20 = 12 hours.

###### 10. A

V = ?r2h. V = 3.14 x (32) x 12. 3.14 x 9 x 12 = 339.12.
