y = kx
'k' is the constant of proportionality, or otherwise known as constant of variation.
y = 90
x = 3
90 = k(3)
90 = 3k
3k/3 = 90/3
k = 30
The constant of proportionality is 30.
Answer:
55/100
Step-by-step explanation:
22 of the 40 questions are answered correctly.
To find the percentage I multiply 22/40 by 100/100(it is equal 1)
(22/40)*100/100 = (22*100/40)/100 =55/100
Answer:
ft
Step-by-step explanation:
take angle b as reference angle
using sin rule
sin 45 = opposite / hypotenuse
= 17 / BC
BC =17 /
BC = 17 * 
BC = ft
Answer:
x=ln(61)/ln(4)
Step-by-step explanation:
4^x+3=64
4^x=64-3
4^x=61
x=ln(61)/ln(4)
