Ateacher needs 256 lengths of string cut to 40 cm each. if balls of string are 30 cm long how many balls will be needed

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

Given: and prove: what is the missing reason in the proof? given transitive property alternate interior angles theorem converse alternate interior angles theorem

Can someone plz me understand how to do these. plz, show work. in exercises 1-4, rewrite the expression in rational exponent form.[tex]\sqrt[4]{625} \sqrt[3]{512} (\sqrt[5]{4} )³ (\sqrt[4]{15} )^{7}\\ (\sqrt[3]{27} )^{2}[/tex]
