Ireally need ! angle pqr is formed by segments pq and qr on the following coordinate grid: angle pqr is rotated 90 degrees counterclockwise about the origin to form angle p′q′r′. which statement shows the measure of angle p′q′r′? a. m∠p′q′r′ = 90 degrees b. m∠p′q′r′ = 180 degrees c. m∠p′q′r′ = m∠pqr d. m∠p′q′r′ = 2 ⋅ m∠pqr

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
