Answer:
Cluster random sample
Step-by-step explanation:
Oranges: 2x3.50=7
Apples: 4x3.25=13
Carrots: 2x1.90=3.80
Potatoes: 1.20
Cost: 7+13+3.8+1.2=25
Discount: 25x0.05=1.25
Total cost: 25-1.25=23.75
He spent $23.75 at the farmers market.
Given that y varies inversely as x then:
y=k/x
where
k is the constant of proportionality given by:
k=yk
but
y=27 when x=2
thus
k=27×2=54
hence the function will be:
y=54x
The value of x when y is 9 will be:
9=54x
thus
x=9/54
x=1/6
For the blue picture, use Pythagorean theorem. So 8.7^2 + x^2 = 32^2. Now solve for x and that’ll give you the missing side
