Answer:
About 35 trees in a state park are infected with insects
Step-by-step explanation:
we know that
7 out of 190 trees are infected with insects
so
using proportion
Find out about how many of the 950 hemlock trees in a state park are infected with insects
therefore
About 35 trees in a state park are infected with insects
Answer: Use the formula y = mx + b in order to solve for b. Then, plug in known vaules.
y= -13x -57

Answer:
4 x 1 = 4 x 3 = 12 = 4 x 3
Step-by-step explanation:
sorry I'm having trouble with this too
Answer:
4/3
Step-by-step explanation:
To know this, let's write down the formulas for the volume of cylinder and sphere.
Vs = 4/3πr³ (1)
Vc = π r² h (2)
Now, we do have a little problem here and its the fact that the sphere do not have a height like the cylinder do. But in this case so if you want to have an idea of the fraction of the volume, we will assume that the cylinder has the same height as its radius. Assuming this we have the following:
Vs / Vc = 4πr³ / 3πr²h
Vs/Vc = 4πr³ / 3πr³
From here, we can cancel out the values of π and r³:
Vs/Vc = 4/3
<h2>
Vs = 4/3 Vc</h2>
Thus we can conclude that the volume of the sphere is 4/3 the volume of a cylinder.
Hope this helps
