At the end of the school year, a high school chemistry teacher asks one of the students to stay after school and help clean the storage room. While cleaning, the student finds a rectangular block of metal that is not labeled and is therefore unknown. a) The student wants to identify the metal using density. The student measures each side of the block (using a centimeter ruler) and determines the length is 3.00 cm, height is 5.00 cm, and width is 5.00 cm. The student then takes the mass of the block using an electronic balance and reports the mass as 337.50 g. What is the density of the rectangular block

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.

Acar travels at an average speed of 52 miles per hour. how long does it take to travel 299 miles

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
