Nezzie is shopping for items for her daycare because the store is having a sale where everything in the store is 10% off. Nezzie buys a playhouse for $100.29 and a music center for $59.99. She has a coupon for an additional 15% off on the playhouse. Before tax, Nezzie estimates that her total, after discounts, will be about $122. Determine if Nezzie has estimated correctly. a. Yes. Nezzie has estimated correctly. b. No. Nezzie has taken 25% off from the music center, which is not correct. c. No. Nezzie has taken successive discounts on the total, but the coupon is just on the playhouse. d. No. Nezzie has estimated 10% off the original price of the playhouse not the discounted price.

The figure below shows a parallelogram ABCD. Side AB is parallel to side DC and side AD is parallel to side BC: A quadrilateral ABCD is shown with the two pairs of opposite sides AD and BC and AB and DC marked parallel . The diagonal are labeled BD and AC A student wrote the following sentences to prove that the two pairs of parallel opposite sides of parallelogram ABCD are congruent: For triangles ABD and CDB, alternate interior angles ABD and CDB are congruent because AB and DC are parallel lines. Alternate interior angles ADB and CBD are congruent because AD and BC are parallel lines. DB is congruent to DB by _______________. The triangles ABD and CDB are congruent by ASA postulate. As corresponding parts of congruent triangles are congruent, AB is congruent to DC and AD is congruent to BC by CPCTC. Which phrase best completes the student's proof?

A city’s bus line is used more as the urban population density increases. The more people in an area, the more likely bus lines will be utilized. The population of Belmont, MA, is 24,729 and covers an area of 4.66 mi2. The population of Easton, MA, is 23,112 and covers an area of 28.4 mi2. Which city’s residents are more likely to use public buses? Explain. The residents of Belmont are more likely to use public transportation because the city has the highest population density. The residents of Easton are more likely to use public transportation because the city has the highest population density. The residents of both cities will not use the bus line because the population density is too high. The residents of both cities are equally likely to use public transportation because the population densities are equal.
