Answer:
z = 2.7x/r²y
Step-by-step explanation:
z = kx/r²y
½ = k × ⅓ ÷ (3² × ⅕)
½ = ⅓k × 5/9
k = 27/10 = 2.7
z = 27x/10r²y
z = 2.7x/r²y
Answer:
45% decrease
Step-by-step explanation:
The formula for percent of decrease/ increase is
Original - change/ original
So 40 - 22 = 18
18/40 = 0.45
Turn 0.45 to percent by moving the decimal two spaces to the right
45%
You can check by multiplying the original number by the percentage. So,
40 x 0.45 = 18
5 1/8 8 goes into 41 5 times with 1 left over
