Math it's just multiplying and dividing fraction. just 7 & 8
1 answer:
7.
find a common denominator
it will turn into 54 over 45 times -50 over 45
multiply across, leaving the denominator the same
divide the numerator by the denominator
leaving you with 60
ANSWER: 60
8.
Turn the whole number into a fraction by multiplying 3 by 8, also write an 8 under your answer, put the negative in front of the fraction
now we have -24 over 8 divided by 7 over 8
divide -24 by 7
now we have -3 over 8

Answer:
a) θ = b) r = 31.27 inch
Step-by-step explanation:
(a)
area of sector: * r² * θ
384 = * r² * θ
384 = * (24)² * θ
θ = 384/288
θ =
(b)
384 = * r² *
r² = 384 * 2 *
r² = 977.848
r = √977.848
r = 31.27 inch
