Answer:
90.84
Step-by-step explanation:
49.7+41.14= 90.84
Answer:
48,558
Step-by-step explanation:
The function which models the relationship between the elapsed time, t in years, since 2010 and the town's population, P(t), is given as:

Now, 2020-2010=10 Years
Therefore we are required to calculate the population of the town 10 years after.
To do this, we simply substitute t=10 in the function.

According to the model, the population in Fall River will be 48,558 in the Year 2020.
Answer:
The volume of the sphere is 14m³
Step-by-step explanation:
Given
Volume of the cylinder = 
Required
Volume of the sphere
Given that the volume of the cylinder is 21, the first step is to solve for the radius of the cylinder;
<em>Using the volume formula of a cylinder</em>
The formula goes thus

Substitute 21 for V; this gives

Divide both sides by h


The next step is to solve for the volume of the sphere using the following formula;

Divide both sides by r

Expand Expression

Substitute 



Multiply both sided by r

------ equation 1
From the question, we were given that the height of the cylinder and the sphere have equal value;
This implies that the height of the cylinder equals the diameter of the sphere. In other words
, where D represents diameter of the sphere
Recall that 
So, 

Substitute 2r for h in equation 1



Hence, the volume of the sphere is 14m³
Answer:
Okay so im seeing you need help okay I will tell you how to do number 21 as an example
Step-by-step explanation:
Look for a commen donominater of the 3/8 and 1/3 the denominater would be 24 so 8 times 3 and 3 times 3 so those would be 9/24 and 3/24 , do the 8 plus the ten and you get 18 so 18+ 9/24+3/24= 18 12/24, or 18 1/2
Answer:
<h2>The answer is 58 m</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
length = 17 m
width = 12 m
Substitute the values into the above formula and solve for the perimeter
We have
Perimeter = 2(17) + 2(12)
= 34 + 24
We have the final answer as
<h3>58 m</h3>
Hope this helps you
