Answer:
184.9 ft³
Step-by-step explanation:
In order to find the volume, we need to know the radius. We can find that from the circumference.
C = 2πr
r = C/(2π) = 29.516/(6.28319) ≈ 4.6976 . . . . feet
The volume of the cone is found using the formula ...
V = 1/3πr²h
V = 1/3π(4.6976 ft)²(8 ft) ≈ 58.847π ft³
V ≈ 184.9 ft³ . . . . volume of the cone

Find the area of the circle to the nearest whole number, if necessary.
Answer:
Area of a Circle = πr²
R=Diameter/2
=21mm
=π(21)²
=1385.44mm²
To the nearest whole number
= 1385mm²
The answer is in mm². It may differ if the given answer is in m². You can get this by converting your radius to meters. This is done by dividing 21mm by 1000.

Assume that the salaries of elementary school teachers in the United States are normally distributed with a mean of $37,000 and a standard deviation of $5000. What is the cutoff salary for teachers in the bottom 10%
Answer:
New cut off salary = 30,592
Step-by-step explanation:
Given:
Normal distributed mean = $37,000
Standard deviation = $5000
Cut off salary = 10%
Find:
New cut off salary
Computation:
Z - left tale value of 10% is -1.2816
Corresponding x-value using x = zs + u
New cut off salary = (-1.2816)(5,000) + 37,000
New cut off salary = -6,408 + 37,000
New cut off salary = 30,592

Advertising A bank manager wants to encourage new customers to open accounts with principals of
at least $2,500. He decides to make a poster advertising a simple interest rate of 3%. What must the
principal be if the bank manager also wants to advertise that one can eam $10 the first month? Can
the poster correctly say, "Open an account of $2,500 and earn at least $10 interest in 1 month!"?
Explain your answer (be careful he said 1 MONTH).
Answer:
The poster say, "Open an account of $3,500 and earn at least $10 interest in 1 month!" is correct
Step-by-step explanation:
Given, A bank manager wants to encourage new customers to open accounts with principals of at least $3,500.
He decides to make a poster advertising a simple interest rate of 4.8%.
We have to find what must the principal be if the bank manager also wants to advertise that one can earn $10 the first month
We know that, banks offer simple interest
In our problem, simple interest = $10, rate = 4.8%, time = 1 month
Let us see Can the poster correctly say, "Open an account of $3,500 and earn at least $10 interest in 1 month!"?
So now, in our problem, amount = $3500, rate = 4.8% and time = 1 month =
So, the statement is correct.
Hence, amount to be invested is $2500 and poster says correctly.
how to find x in 11x+63=360
Answer:
you get 27
Step-by-step explanation:
subtract 63 from both sides
then divide by 11
Answer:
answer: 27
Step-by-step explanation:
To find this you just have to do 11 multiplied by x + 63 so 11 × 27 = 297 and 297 + 63 = 360 so x = 27 Hope that helps!

Identify the lateral area and surface area of a regular triangular pyramid with base edge length 10 ft and slant
height 14 ft
Answer:
L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
Lateral surface area of the regula triangular pyramid is 210 ft²
Surface area of the regular triangular pyramid is 253.30 ft²
Lateral area and Surface area of a triangular pyramid: Expression for the lateral area of a regular triangular pyramid is given by,
Lateral surface area = 3(Area of one lateral triangular side)
Expression for the total surface area is given by,Surface area = Area of the triangular base + Lateral surface area
Given in the question,
Base with the edge length = 10 feet Slant height = 14 ftLateral surface area = [tex]3(\frac{1}{2})(\text{Base})(\text{Slant height})[/tex]
= [tex]\frac{3}{2}(10)(14)[/tex]
= 210 ft²
Area of the regular triangular base = [tex]\frac{\sqrt{3} }{4}(a)^2[/tex]
= [tex]\frac{\sqrt{3} }{4}(10)^2[/tex]
= 25√3 ft²
= 43.30 ft²
Therefore, total surface area = 210 + 43.30
= 253.30 ft²
Hence, lateral surface area of the regula triangular pyramid is 210 ft²
Surface area of the regular triangular pyramid is 253.30 ft²

SOMEONE PLZ HELP ME T_T
Answer:
7x - 1
Step-by-step explanation:
Whole rectangle:
Length = x + 5
Width = x - 1
Area of the whole triangle = length × width
= (x + 5) (x - 1)
= x² - x + 5x - 5
= x² + 4x - 5
Unshaded rectangle:
Length = x + 1
Width = x - 4
Area of the unshaded rectangle = length × width
= (x + 1) (x - 4)
= x² - 4x + x - 4
= x² - 3x - 4
Area of the shaded region = Area of the whole rectangle - Area of the unshaded rectangle
= (x² + 4x - 5) - (x² - 3x - 4)
= x² + 4x - 5 - x² + 3x + 4
= 7x - 1
Area of the shaded region = 7x - 1
