3 times sum of a number and nine is 12
Answer:
-5 is the missing number.
Step-by-step explanation:
Let's write the equation.
Represent the number with x.
3( x + 9 ) = 12
Now, we solve for x.
Divide by 3 on both sides.
x + 9 = 4
Now, subtract by 9 on both sides.
x = -5
The number is -5.

1. If the diameter of a circular object is 10 feet. Find the radius and the circumference. Use 3.14 for π.
2. Find the perimeter of the window. R = 4ft
Answer:
1.
[tex]Radius = 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
2.
[tex]Perimeter = 25.12\ ft[/tex]
Step-by-step explanation:
Solving (1):
Given
[tex]Diameter = 10ft[/tex]
Required
Determine the radius and circumference
Radius is calculated as follows:
[tex]Radius = \frac{1}{2} * Diameter[/tex]
[tex]Radius = \frac{1}{2} * 10ft[/tex]
[tex]Radius = 5ft[/tex]
The circumference is calculated using:
[tex]Circumference = 2 * \pi * Radius[/tex]
[tex]Circumference = 2 * 3.14 * 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
Solving (2):
Given
[tex]R = 4ft[/tex]
Assume that the window is circular, the perimeter is calculated as follows:
[tex]Perimeter = 2 * \pi * R[/tex]
[tex]Perimeter = 2 * 3.14 * 4ft[/tex]
[tex]Perimeter = 25.12\ ft[/tex]

find the exact length of the third side
Step-by-step explanation:
if the length of the third side = a
a² + 13² = 85²
a² + 169 = 7,225
a² = 7,225 - 169
a² = 7,056
a = square root 7,056
a = 84
So, the length of the third side is equal 84 unit.
Answer:
84
Step-by-step explanation:
According to Pythagoras theorem
x²+y²=z²
x=√z²-y²
x=√85²-13²
x=√7225-169
x=√7056
x=84
in right triangle RST altitude TV is drawn to hypotenuse RS If RV = 12 and RT = 18, what is the length of SV
Answer:
12
Step-by-step explanation:
Given that:
RV = 12 and RT = 18
Kindly refer to attachment for triangle diagram:
Using the altitude on hypotenus theorem :
Length of RS = 12 + a
RT² = RV * RS
18² = 12 * (12 + a)
324 = 12(12 + a)
324 = 144 + 12a
324 - 144 = 12a
180 = 12a
Divide both sides by 12
180/12 = a
15 = a
Hence, SV = 12
0.5(x+2,000)=3,000

STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet
A) -10°F B) 20°F C) 10°F D) -20°F
Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
Given that, the altitude, [tex]A[/tex] = 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
And value of altitude, [tex]A[/tex] = 5,000 feet
Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].
Temperature in [tex]^\circ F[/tex] =
[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]
Therefore, the answer is:
A) -10°F

For many waiting line situations, the arrivals occur randomly and independently of other arrivals and it has been found that a good description of the arrival pattern is provided by a
Answer:
Poisson Probability distribution.
Step-by-step explanation:
We are told that arrivals occur randomly and independently of other arrivals. This can be analyzed with Poisson Probability distribution because In statistics Poisson distribution is simply a statistical distribution that shows the number of times an event will likely occur within a specified amount of time.
This distribution is normally used for independent events which occur at a constant rate within a given time interval.
