2.40 / 8 = 0.3
0.3 * 3 = 0.9
Answer: 0.9 is 3/8 of 2.40
Answer:
V₂=28cm³
Step-by-step explanation:
<u>Way 1</u>
The volume of a cone is 
, and h₁ = 30 cm but the base (Ba₁) is 14 cm², so
, where Ba= Base area
if h₂=7cm and Ba₂=12cm² then
<u>Way2</u>
If the volume of a cone varies jointly as the height of the cone and the area of the base, then we must find the relationship between the bases and heights of the cones
Ba₁*h₁ = 30cm*14cm² = 420cm³
Ba²*h²= 7cm*12cm² = 84cm³
420/84 = 5; ratio = 5 also
V₂=V₁/5 ⇒ V₂=140cm³/5 = 28cm³
Answer:
plug in 2 everwhere you see a variable
Step-by-step explanation:
When you multiply a positive number by 0.95, the product is smaller than the number.
The function is
f(x) = 9000(0.95)^x
Choice A is false.
Choice B is true.
At 2 years, x = 2
f(x) = 9000(0.95)^x
f(2) = 9000(0.95)^2 = 8122.5
Choice C is true.
At 4 years, x = 4.
f(4) = 9000(0.95)^4 = 7331
Choice D is false.
<span>The domain values, in the context of the situation, are limited to whole numbers.
You can calculate what the bee population will be after 5.5 years.
The domain can include numbers that are not whole numbers.
Choice E is false.
</span><span>The range values, in the context of the situation, are limited to whole numbers.
The range is the number of bees alive. That has to be a whole number since you can't have a fraction of a bee alive.
Choice F is true.
