The volume of a regular hexagonal pyramid will be 554.3 cubic inches.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height, and A be the base area of the pyramid. Then the volume of the pyramid will be given as,
Volume = (1/3) × A × h
The base area is calculated as,
A = 6 x (1/2) x 8 x 8 x sin 60°
A = 3 x 8 x 8 x 0.866
A = 166.28 square inches
The volume of a regular hexagonal pyramid is calculated as,
V = 1/3 x 166.28 x 10
V = 554.3 cubic inches

Answer: 132.7 square inches
Area of a circle formula: [tex]\pi r^{2}[/tex]
Because we know that a diameter is twice the size of the radius and the diameter is 13 inches, we can divide 13 by 2 to get 6.5
Plug in this value into the formula, to get [tex]\pi (6.5^{2})[/tex]. Simplify the equation to get [tex]\pi (42.25)[/tex]. Multiply to get 132.7.
Answer:
It's A
Step-by-step explanation:
To find area= pie*raduis*radius
To find raduis you'll divide diameter by two
so 13 divided by 2 is 6.5
6.5*6.5*3.14=132.7

Based on data taken from airline fares and distances flown, it is determined that the equation of the least-squares regression line is ŷ = 102.50 + 0.65x, where ŷ is the predicted fare and x is the distance, in miles. One of the flights was 500 miles and its residual was 115.00.
What was the fare for this flight?
102.50
312.50
427.50
542.50
Answer:
542.50
Step-by-step explanation:
Given:
Least square regression equation :
y = 102.50 + 0.65x + residual
y = predicted fare
x = distance in miles
Intercept = 102.50
Slope = 0.65
Distance in miles, x = 500 miles
y = 102.50 + 0.65(500) + 115
y = 102.50 + 325 + 115
y = 427.5 + 115
y = 542.50
Answer:
Don't know why everyone downvoted the first answer. Maybe you guys suck at clicking. It's correct.
Your answer is 542.50 (D)
102.50 + 65(500) = 427.5
427.5 + 115 = 542.50
You add the residue.

Please find x and y!!!!!! URGENT! Bots taken down
Answer:
x = 11, y = 22
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{11\sqrt{3} }{x}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by x )
11[tex]\sqrt{3}[/tex] = x × [tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
11 = x
Using Pythagoras' identity in the right triangle
y² = x² + (11[tex]\sqrt{3}[/tex] )² = 11² + 363 = 121 + 363 = 484 ( square root of both sides )
y = [tex]\sqrt{484}[/tex] = 22

Which equation is equivalent to 3(1 – x) = 2x - (6x+3)?
Answer:
3-3x=-4x-3
Please correct me if I am wrong.
Step-by-step explanation:
Option A is equivalent to 3(1 – x) = 2x - (6x+3) That is :
3 – 3x = -4x+3
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
The given equation is :
3(1 – x) = 2x - (6x+3)
multiply 3 with inside the parenthesis in the left side of equation :
3 – 3x = 2x - (6x+3)
subtract 2x with 4x and simplify :
3 – 3x = 2x - 6x+3
3 – 3x = -4x+3
this result is equivalent to option A which will give the same result.
Therefore, Option A is equivalent to 3(1 – x) = 2x - (6x+3).

Cara leaves her house at 10:03 and arrives at the library at 10:17. Irena leaves her house at 11:55 and arrives at the library at 12:06. Who takes longer to get to the library? How many minutes longer? Blank takes longer. She takes blank minutes longer
Answer: Cara takes longer to get to the library. She used 3 minutes more
Step-by-step explanation:
Cara leaves her house at 10:03 and arrives at the library at 10:17. The number of minutes used by Cara will be:
= 10.17 - 10.03
= 14 minutes
Irena leaves her house at 11:55 and arrives at the library at 12:06. The number of minutes used by Irena will be:
= 12.06 - 11.55
= 11 minutes
Cara takes longer to get to the library. She used (14 - 11) = 3 minutes more

Shannon went to an auto repair shop and paid $339.50, which included parts that cost $112 and 3.5 hours of labor. Joni went to an auto repair shop and paid $455, which included parts that cost $310 and 2.5 hours of labor. Which correctly compares the cost of the labor?
Answer:
Option A, Shannon paid $ 7 per hour to labor than Joni
Step-by-step explanation:
Total amount paid by Shannon = $339.50
Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)
Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5
Total cost of 1 hours of labor paid by Shannon $65 per hour
Total amount paid by Joni = $455
Total cost of 2.5 hours of labor paid by Joni = $455- $$310
Total cost of 1 hours of labor paid by Joni = $145/2.5
Total cost of 1 hours of labor paid by Joni = $ 58
Hence, Shannon paid $ 7 per hour to labor than Joni

The image of the hexagon is missing, so i have attached it.
Answer:
∠1 = 36°
Step-by-step explanation:
From the image attached, we can see that the polygon is regular and has 10 sides.
Formula for an interior angle of a regular polygon is;
θ = 180(n - 2)/n
Where n is the number of sides of the polygon.
Thus;
θ = 180(10 - 2)/10
θ = 144°
Now, ∠1 forms a straight line with one of the interior angles of the polygon.
Thus, θ + ∠1 will be equal to 180° because sum of angle on a straight line is 180°
Thus;
144° + ∠1 = 180°
∠1 = 180° - 144°
∠1 = 36°
Paragraph Finding the part, percent, and the whole Styles 1) Sixteen students in the school band play clarinet. Clarinet players make up 20 %v of the band. How many students are in the school band?
Answer:
80
Step-by-step explanation:
You know that 20% of the school band are 16 clarinet players, or 16 is 20% of the band.
You can set up the equation 0.2x = 16 and divide both sides by 0.2. You then get that x = 80, so there are 80 kids in the school band.
