joe measured a brick using a ruler with centimeters and got 9 cm. he then measured the same brick using a ruler with millimeters and got 90 mm. are these measurements equivalent?

yes

Step-by-step explanation:

1 cm=10mm. if 1cm=10mm what about 9cm

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
