Answer: Mass of trunk = 6100 kg

Step-by-step explanation:

The trunk of the tree is cylindrical. We would apply the formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

h represents the height of the cylinder.

r represents the radius of the cylinder.

π is a constant whose value is 3.14

From the information given

Height = 38 meters

Diameter of circular base = 0.62 meters.

Radius = diameter/2 = 0.62/2 = 0.31 meters

Therefore,

Volume of trunk = 3.14 × 0.31² × 38 =

11.47 m³

Mass = density × volume

Mass of the trunk = 520 kilograms per cubic meter

Mass of trunk = 520 × 11.47 = 6056.16 kg

Rounding to the nearest hundred,

Mass of trunk = 6100kg

Fun fact:

Answer:

The relationship is positive.

The model predicts a score of 60.

Not sure what part b is.

Step-by-step explanation:

Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.

By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.

15(15b−7)=3b−9 plz help meee
Romashka-Z-Leto [24]

Answer:

B=16over37

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15(15b−7)=3b−9

(15)(15b)+(15)(−7)=3b+−9(Distribute)

225b+−105=3b+−9

225b−105=3b−9

Step 2: Subtract 3b from both sides.

225b−105−3b=3b−9−3b

222b−105=−9

Step 3: Add 105 to both sides.

222b−105+105=−9+105

222b=96

Step 4: Divide both sides by 222.

222b

222

=

96

222

Then simplify
