You have a hemisphere with a volume of 6. What is the surface area with a sphere with the same diameter. Round to the nearest thousandth.
Answer:
(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)
For a sphere of radius R, the volume is:
V = (4/3)*pi*R^3
Where pi = 3.14
And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:
V = (1/2)*(4/3)*pi*R^3
We know that the volume of the hemisphere is 6 m^3, then we have the equation:
6 m^3 = (1/2)*(4/3)*3.14*R^3
Now we can solve this for R.
6 m^3 = 2.1*R^3
∛(6 m^3/2.1) = R = 1.41 m
The radius of the hemisphere is 1.41m
Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)
For a sphere of radius R, the surface is:
S = 4*pi*R^2
Then the surface of this sphere is:
S = 4*3.14*(1.41 m)^2 = 24.971 m^2
I don't know what this is.
Y=52(0.42)^x identify if it's growth or decay and determine the percentage rate of increase or decrease
Answer:
58%
Step-by-step explanation:
Given the exponential relation :
Y=52(0.42)^x
Since 0.42 is less than 1, then we can infer that the expression is a Decay function ;
. General form of a exponential function :
y = A(1 - r)^x ; r = Decay rate
Comparing the general equation with the equation given ;
The percentage rate of decrease is obtained thus :
1 - r = 0.42
1 - 0.42 = r
r = 0.58
Rate = 0.58 * 100%
Rate = 58%

Answer:
-79.78 (really stinking cold)
Step-by-step explanation:
Solving the equation will go like this:
5/9(F - 32) = -62.1
multiply both sides by 9 to get rid of the fraction
5 (F - 32) = -558.9
divide both sides by 5
F - 32 = -111.78
add 32 to both sides
F = -79.78

The segment shown below could form a triangle
No this will not form a triangle.option B is correct.
what is the power times a power
where does the power go in a equation
how do you put a power in a equation
Answer:
The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.

Answer:
360m²
Step-by-step explanation:
Surface area of Pyramid=4*Area of Triangle+Area of Square
Area of Triangle=(1/2)*Base*Height
Area of Square=Side²
Area of 4 Triangles=4*(1/2)*10*13=260m²
Area of square=10²=10*10=100m²
Total Area=260m²+100m²=360m²

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 363 square feet. The width of the basement is 1 3 its length. What is the length of Louis's basement? The length is feet.
Answer:
the length is 33 feet
Step-by-step explanation:
The computation of the length is shown below:
Let us assume the length be x
So the width be 1 by 3 x
And the area is 363 square feet
So
As we know that
Area = length × width
363 = x × 1 ÷ 3 x
363 = 1 ÷ 3x^2
Now
363 × 3 = x^2
1089 = x^2
x = 33 feet
hence, the length is 33 feet
The average distance from the Earth to the moon is 238,855 miles. What is the distance rounded to the nearest thousand?
Answer:
239,000
Step-by-step explanation:
Look at the digit to the right of the place you're rounding to. In this case, we are rounding to the thousands, so we look at the digit in the hundreds place. It's 8, which is above 5 (5 and above you round up. 4 and below, you round down). Because the 8 is above 5, we go back to the thousands place and bump the number (8) up one (to 9).

1. If X+Y=7 and xy = 10 , then x3+ y3
Answer:
final answer is 21
Step-by-step explanation:
since x+y=7 and xy=10
2+5=7 and 2(5)=10
so,
(5)3=15
(2)3=6
15+6= 21
A chocolate company selects 1200 random packages to check their weight it finds that 30 packages have an incorrect weight. how many packages out of 6000 should the company predict have an incorrect weight.
Given the definitions of f(x) and g(x) below, find the value of g(f(5)).
f(x) = 2x – 10
g(x) = x^2 + 6x – 8
I don’t need work I am just looking for the answer !
gf(x) = g(x^-1) = x^2 + 6x - 8
f(x) = 2x - 10
gf(x) = 6 ( 2x - 10) - 8
gf(x) = 12x- 60 - 8
gf(x) = 12x -68
gf(5) = gf(x) = 12x - 68
gf(5) = 12(5) - 68
gf(5) = 60 - 68
gf(5) = -8

A car was purchased for $24,000. Its value is predicted to decay exponentially, decreasing by 13% each year. Write an equation to determine the value of the car.
Answer:
y= P(0.87)^t
Step-by-step explanation:
Given data
Price P= $24,000
Rate of decay in price= 13%
The expression in terms of y, p and t is
y=P(1-r)^t
y= P(1-0.13)t
y= P(0.87)^t
