Answer:
22sqrt(3)/3
You are correct.
Step-by-step explanation:
You have a 30-60-90 triangle.
In a 30-60-90 triangle, the hypotenuse is twice the length of the short leg. The long leg is sqrt(3) times the length of the short leg.
You are given the length of the long leg.
1) Find the length of the short leg.
HG = GI/sqrt(3) = 11/sqrt(3)
2) Find the length of the hypotenuse, HI.
HI = 2HG = 2(11/sqrt(3)) = 2(11/sqrt(3))*(sqrt(3))/(sqrt(3)) = 22sqrt(3)/3
Mari has a part time job. She earns $7 an hour. She makes at most $143.50 a week. What is the greatest number of hours that she works?
Mari works at most 20 hours per week.
Explanation:To find the greatest number of hours that Mari works, we can divide her total weekly earnings by her hourly wage. In this case, we divide $143.50 by $7. The result is approximately 20.5. Since Mari cannot work a fraction of an hour, we round down to the nearest whole number. Therefore, the greatest number of hours she works is 20 hours.

Which equation exemplifies the Associative property of addition?
8+2=2+8
4+(2+1) = (4+2)+1
4+5=1+8
9(5•6)=(9•5)6
Answer:
Equation which exemplifies the associative property of addition is:
4+(2+1) = (4+2)+1
Step-by-step explanation:
The associative property of addition says that:
if a,b and c are the three terms
Then,
a+(b+c)=(a+b)+c
which is given in the equation:
4+(2+1) = (4+2)+1
Hence, equation which exemplifies the associative property of addition is:
4+(2+1) = (4+2)+1

The statement " If two lines are intersected by a transversal so that the alternate interior angles are congruent, then the lines are paralle " is true.
What is Property of Parallel lines?If the corresponding angles created by any two lines are equal, then the lines are said to be parallel.If the alternate internal angles created are equal, any two lines are considered to be parallel.If the alternate outside angles created are equal, any two lines are considered to be parallel.Given:
If two lines are intersected by a transversal so that the alternate interior angles are congruent, then the lines are parallel.
We know whenever we have parallel line intersected by transversal line then we Alternate Interior Angle, Corresponding Angle, Alternate Exterior Angle, are congruent.
Thus, the statement showing when we have Alternate Interior Angle congruent then the lines were be parallel lines.

D. (1, 1/2) (2, 1/4) (3, 1/6) (4, 1/8)
The correct answer is:
C. (1, 1/2) (2, 1/4) (3, 1/8) (4, 1/16)
Explanation:
In order to be an exponential function, the y-coordinates of each point should be multiplied by a constant to get the next y-coordinate. For C, we multiply by 1/2:
1/2(1/2) = 1/4; 1/4(1/2) = 1/8; 1/8(1/2) = 1/16
This means it is an exponential function.

A line-marking machine lays down lime powder to mark two equal foul lines on a playing field. If each line for this field measures 311 feet, how many feet of lime powder will be deposited?
The machine will deposit 622 feet of lime powder to mark both foul lines on the playing field.
To solve this problem, we need to consider that the line-marking machine is laying down lime powder to mark two equal foul lines on a playing field. Each foul line measures 311 feet.
Since there are two lines of equal length, we simply need to add the lengths of these two lines together to find the total amount of lime powder deposited.
Here is the calculation:
Length of one foul line = 311 feet
Number of foul lines = 2
Total length of lime powder deposited = Length of one foul line [tex]\times[/tex] Number of foul lines
Total length of lime powder deposited = 311 feet [tex]\times[/tex] 2
Total length of lime powder deposited = 622 feet.

On a clear day you can see about 27 miles from the observation deck of the Empire State Building in New York City. Using the formula below, estimate the height in feet ,h, of the observation deck.
Answer:
Step-by-step explanation:
Alright, lets get started.
Distance we can see from the building d is given as 27 miles.
We are asked to find height of the building h
The formula is given as [tex]d=\frac{5}{6}\sqrt{h}[/tex]
Plugging the value of d
[tex]27=\frac{5}{6}\sqrt{h}[/tex]
Cross multiplying
[tex]\sqrt{h}=\frac{6}{5}*27[/tex]
[tex]\sqrt{h}=32.4[/tex]
Taking square root on both sides
[tex]h=1049.76[/tex]
So, the height of the observation desk is 1050 feet. : Answer

1. List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Answer:
Length
Step-by-step explanation:
mhm
1) The dimensions of the rectangular prism or box which I found are:
Length: 6 inchesWidth: 2.5 inchesHeight: 12 inches (1 foot)2) The shape of the cross-section when the box is cut parallel to the base will be a rectangle.
3) Surface Area of the box is234 in²
4) Surface Area of the box if scaled up by a factor of 10 is 23,400 in²
5) Volume of the box: 180 in³
6) Volume of the box if scaled down by a factor of 1/10 is 0.18 in³
Given:
Dimensions of the box to be:
Length: 6 inches
Width: 2.5 inches
Height: 12 inches (1 foot)
1) The shape of the cross-section when the box is cut parallel to the base will be a rectangle.
2) To calculate the surface area of the box:
Surface Area = 2*(Length*Width + Length*Height + Width*Height)
Surface Area = 2*(6*2.5 + 6*12 + 2.5*12)
Surface Area = 2*(15 + 72 + 30)
Surface Area = 2*(117)
Surface Area = 234 in²
3) If the box is scaled up by a factor of 10, the new dimensions would be:
Length: 6 inches * 10 = 60 inches
Width: 2.5 inches * 10 = 25 inches
Height: 12 inches * 10 = 120 inches
To find the new surface area:
New Surface Area = 2*(60*25 + 60*120 + 25*120)
New Surface Area = 2*(1500 + 7200 + 3000)
New Surface Area = 2*(11700)
New Surface Area = 23,400 in²
4) The volume of the box:
Volume = Length * Width * Height
Volume = 6 * 2.5 * 12
Volume = 180 in³
5) If the box is scaled down by a factor of 1/10, the new dimensions would be:
Length: 6 inches * 0.1 = 0.6 inches
Width: 2.5 inches * 0.1 = 0.25 inches
Height: 12 inches * 0.1 = 1.2 inches
To find the new volume:
New Volume = Length * Width * Height
New Volume = 0.6 * 0.25 * 1.2
New Volume = 0.18 in³

212.54 in3
231.56 in3
850.16 in3
867.34 in3
Answer: 212.54 in3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder: π r² h
Where:
r = radius (also r= diameter /2) h= heightReplacing with the values given:
r = 4.75/2 = 2.375 in
h = 12in
V = π r² h
V= π (2.375)² (12) = 3.14 (5.640625) 12 =212.54 in3
So, the correct option is 212.54in3

Find the derivative of f(x) = 7 divided by x at x = 1.
The solution is, the derivative of f(x) = 7 divided by x at x = 1 is -7.
What is derivative?A derivative is described as either the rate of change of a function, or the slope of the tangent line at a particular point on a function.
here, we have,
given that,
the derivative of f(x) = 7 divided by x at x = 1.
so, we get,
F(x) = 7/x
Same as..
F(x) = 7x^-1
we know that,
d/dx (x^n) = n*x^n-1
so, using this, we get,
Take derivative..
F'(x) = -7x^-2
Plug in x = 1
F'(1) = -7(1)^-2
F'(1) = -7
Hence, The solution is, the derivative of f(x) = 7 divided by x at x = 1 is -7.
