Given: m∠RPQ = 23°; m∠TPR = 85°

If ∠SPR and ∠RPQ are complementary angles, then what is the measure of ∠TPS?
A. 23°
B. 18°
C. 5°
D. 67°

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

the two may have that, even a breakdown is probably offered

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
