1. The dimensions of Joe’s rectangular garden are 18 feet by 12 feet. Joe wants to conduct an experiment to determine whether using fertilizer in the garden makes a difference. The fertilizer costs $0.45 per square foot of ground covered. How much will it cost to cover half of the garden with fertilizer?
A) $216.00 B) $97.20 C) $48.60 D) $24.30
2. A right triangle has measurements of 8 in., 15 in., and 17 in. What is the area of the right triangle?
B) 60 sq in B) 68 sq in C) 120 sq in D) 136 sq in
3. A middle school is selling rolls of wrapping paper for a fundraiser. The school earns $5.00 for each roll of wrapping paper sold. If the school needs to raise $3,000, what is the minimum number of rolls of wrapping paper that need to be sold?
4. Where is the point x located on the number line?
-3 x -2 -1 0 1
