Vanessa has to sweep 4/6 of the court. If you are already 3/6 of the same court, how much do you need to sweep? Help!
exis [7]

Answer:

Step-by-step explanation:

has to sweep 4/6

already swept 3/6

it needs to sweep 1/6 because

4 / 6-3 / 6 = 1/6

Since they are fractions with the same denominator, you place the same denominator and subtract the numerators.

HELP ME PLEASE IVE BEEN STRUGGLING WITH THIS FOR SO LONG
Ber [7]

Answer:

<h2>m∠ACE = 90°</h2>

Step-by-step explanation:

Figure Interpretation:

m∠CBA + m∠CDE = 180

m∠BCA = (180-m∠CBA)/2

m∠DCE = (180-m∠CDE)/2

=======================

Then

m∠BCA + m∠DCE = (180-m∠CBA)/2 + (180-m∠CDE)/2

                                = [360-(m∠CBA+m∠CDE)]/2

                                = [360 - 180]/2

                                = 90

finally,

m∠ACE= 180 - (m∠BCA + m∠DCE)

             = 180 - 90

             = 90
