FORT JEFFERSON The outer wall of Fort Jefferson, which was originally constructed in the mid-1800s, is in the shape of a hexagon with an area of about 466,170 square feet. The length of one side is about (Hint make a quick sketch) 477 feet. The inner courtyard is a similar hexagon with an area of about 446,400 square feet. Calculate the length of a corresponding side in the inner courtyard to the nearest foot. O A. About 467 ft. O B. About 437 ft. O C, About 487 ft. O D. About 457 ft.
Answer:
D to the nearest foot
Step-by-step explanation:
Ratio problem:
outside wall 477 is to the whole area 466,170 as
inside wall ??? is to the inner courtyard 446,400
477 / ??? = 466170 / 446400 solve for ???
(477)(446400) / 466170 = ???
456.77 ft = ???
john simplified 2 square root of 96 to get an answer of 4 square root 24
Explain the error that john made and then correct his mistake
Answer:
Step-by-step explanation:
2√96 = 2* √(4 * 24)
= 2*2√24
= 4√24
That is equal to 2√96 but a simpler result is:
4√24 = 4 * √4*√6
= 4 *2 √6
= 8√6

Mallory walks 7/10 of a mile in 1/5 hour. What is her walking speed in miles per hour?
Answer:
Here walking speed is 3.5 miles per hour
Step-by-step explanation:
Here, we want to calculate the average speed in miles per hour
mathematically, we know that;
speed = distance/time
from the question, the distance is 7/10 miles
The time is 1/5 hour
Thus we have;
Speed = 7/10 divided by 1/5
speed = 7/10 * 5/1 = 7/2 = 3.5 miles per hour

Sam made 30% of goals in his last 6 games. The points his team scored in the games were 112, 89, 95, 77 and 103 points. On average how many goals did Sam score in each of the last 6 games.
Answer:
28.56
Step-by-step explanation:
First we need to calculate the mean average of the numbers
Average = 112+89+95+77+103/5
Average = 476/5
Average = 95.2
If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;
Average of the last six games = 30% of 95.3
Average of the last six games = 0.3 * 95.2
Average of the last six games = 28.56
Hence the required point average is 28.56

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch longer on all sides. What is the combined volume of the two game systems?
Answer:
Combined volume of the two game systems [tex]=416[/tex] cubic inches
Step-by-step explanation:
Volume of a cuboid = length × breadth × height
Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.
So,
Volume of Soham's video game system = 8 × 6 × 2 = [tex]96[/tex] cubic inches
As Sean's video game system measures 1 inch longer on all sides,
the video game system measures [tex]8+2=10[/tex] inches long, [tex]6+2=8[/tex] inches wide, and [tex]2+2=4[/tex] inches tall.
Volume of the video game system = 10 × 8 × 4 = [tex]320[/tex] cubic inches.
Therefore,
Combined volume of the two game systems = [tex]96+320=416[/tex] cubic inches

An object has a mass of 7.2 kg and a density of 0.9 kg/m3.
Find the volume of the object in mº.
Answer:
mass=180kg and the volume=6m³.
then the formula to find density is= mass/volume
using this formula,180kg/6m³=30kg/m³
Answer:
8 m³
Step-by-step explanation:
Let v represent the volume. Recall that density is mass/volume, which here is 0.9 kg/m³. To find the volume of this object, divide the density into the mass:
7.2 kg
--------------- = 8 m³
0.9 kg/m³

which table could represent a function
The table that could represent a function is given by the values
x = { 1 , 2 , 3 , 4 } and f ( x ) = { 2 , 4 , 6 , 2 } where the there exists one value in the range for every domain value.
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the values of x are given as
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
So , when x = { 1 , 2 , 3 , 4 }
The values of f ( x ) should be distinctive and no values of x should have different values for f ( x )
And , f ( x ) = { 2 , 4 , 6 , 2 } represents a function
Hence , the function is f ( x ) = { 2 , 4 , 6 , 2 }

The length of a rectangle is 5 centimeters less than 2 times the width.
a. Write a polynomial expression that represents ( 2 points )
the area of the rectangle.Simplify the expression.
Given:
The length of a rectangle is 5 centimeters less than 2 times the width.
To find:
The polynomial expression that represents the area of the rectangle, then simplify the expression.
Solution:
Let [tex]x[/tex] be the width of the rectangle.
The length of a rectangle is 5 centimeters less than 2 times the width.
2 times the width = [tex]2x[/tex]
5 centimeters less than 2 times the width = [tex]2x-5[/tex]
Length of the rectangle = [tex]2x-5[/tex]
We know that, the area of a rectangle is:
[tex]A=length \times width[/tex]
[tex]A=(2x-5)\times x[/tex]
[tex]A=2x^2-5x[/tex]
Therefore, the required polynomial expression is [tex]A=(2x-5)\times x[/tex] and its simplified form is [tex]A=2x^2-5x[/tex].

Help! This is my math problem
Answer:
Step-by-step explanation:
The problem is that you cannot be sure that either triangle (it actually requires both of them) contain a right angle
What you have so far is SSA which is not one of the fundamental congruency triangles. In order to be certain of congruency the angle must be made up of the 2 given sides. You are certain that SAS will produce congruency. You are not so sure of r SSA. There are proofs of this on the internet. I urge you to look into it. Though not long, following it step by step takes a lot of patience. A cup of strong coffee is a good idea.
Car rental agencey a charges $50 per day plus 10 cents per mile driven agency b charges $20 per day plus 30 cents per mile driven for a one day rental it is cheaper to rent from ange a if you drive more
Answer:
D) 150 miles.
Step-by-step explanation:
The computation is shown below:
Given that
The Cost of the car rental agency of A is $50 + 0.10 per mile
The Cost of the car rental agency of B is $20 + 0.30 per mile
Here we assume the per mile be x
Now we equate these equations
SO,
$50 + 0.10x = $20 + 0.30x
$30 = 0.20x
x = 150
SO it would be more than 150 miles

slope = 1
Step-by-step explanation:
Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope. Substitute the x and y values of (7,3) and (5,1) into the formula and solve like so:
[tex]m = \frac{(1)-(3)}{(5)-(7)} \\m = \frac{1-3}{5-7} \\m = \frac{-2}{-2} \\m = 1[/tex]
So, the slope of the line is 1.
