Answer:
880m
Step-by-step explanation:
2.5cm = 400m
1cm = 400/2.5
=160m
5.5cm = 160 × 5.5
=880m
V=πr²(1/3)(h)
d=6, therefore r=3 and
90=(3)²(1/3)(h) ... I didn't include the pi because it isn't in the answer
90=3h
h=30
200 sections will cost $7439.
We first see if the rate of change, the slope, is the same between data points. If it is, the function will be linear. We use the formula
m = (y₂ - y₁)/(x₂ - x₁)
For the first two data points, we have
m = (1889-409)/(50-10) = 1480/40 = 37
For the second two data points, we have
m = (4664-1889)/(125-50) = 2775/75 = 37
Now that we know the slope is the same, we can write the equation:
y - y₁ = m(x - x₁)
y - 409 = 37(x - 10)
y - 409 = 37x - 370
Add 409 to both sides:
y = 37x + 39
Using 200 as x,
y = 37(200) + 39 = 7439
Answer:
proportional/noncongruant
Step-by-step explanation:
This is because when you dilate an image it changes size and that means the image is not congruent to the preimage but they will stay proportional since they keep the same shape.
