A personal identification number (PIN) consists of 3 numbers 0 – 9. What's the probability someone's PIN number consists of only 1 number. For example 000, 111, 222, etc.
Answer: [tex]0.34[/tex]
Step-by-step explanation:
given data:
numbers contained in pin = 3
numbers pin can be gotten from = 0-9
solution:
0,1,2,3,4,5,6,7,8,9 = 10
probability the pin consist of only 1 number
[tex]= \frac{1}{10} + \frac{1}{9} + \frac{1}{8} \\\\[/tex]
[tex]= \frac{121}{360} \\[/tex]
[tex]= 0.34[/tex]

In a direct variation equation F(x)=6 when x=4
Answer: C. f(x)=1.5x
Step-by-step explanation:
Here's the complete question:
In a direct variation equation f(x) = 6 when x = 4. what is the direct variation equation
A-f(x)=6x
B-f(x)=4x
C-f(x)=1.5x
D-f(x)=0.67x
The direct variation equation will be:
6 = kx
When x = 4, this will be:
6 = 4k
k = 6/4
k = 1.5
Therefore, the direct variation equation is: f(x)=1.5x
Solve for y:
32x + 14y = 23
A large aquarium should contain 10,000 liters of water when it is filled correctly. Fish will get sick if the aquarium gets down to 4,000 liters or less. One day over the weekend, there is an accident, and the tank cracks in 4 places, causing water to empty out of the aquarium at a rate of 20.5 liters per hour. The aquarium workers did not catch the leaks until 2 days later. How much water was left in the tank when the aquarium workers finally caught the leak? Based on the level of water, were fish sick?
Answer:
9016 litres left
Step-by-step explanation:
The fish were not sick.
You would multiply 20.5 by 48 which is the amount of hours in 2 days then subtract that amount from 10000 to see how much is left

What is 6 - 2 over 3 (x + 5) = 4x algebraically
Answer: x = 4/7
Explanation and steps is in the image below.
The solution to the given equation 6 - 2(x + 5)/3 = 4x is x = 4 /7.
What is the equation?The equation is defined as an algebraic statement that has a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question
6 - 2(x + 5)/3 = 4x
Apply the distributive property of multiplication,
6 - (2x + 10)/3 = 4x
(2x + 10)/3 + 4x = 6
2x/3 + 10/3 + 4x = 6
2x/3 + 4x = 6 - 10/3
Take the LCM in the above equation,
14x/3 = 8/3
14x = 8
x = 8 / 14
x = 4 /7
Thus, the solution to the given equation 6 - 2(x + 5)/3 = 4x is x = 4 /7.

1 2/3 yards of chain cost 9.00.
How much money for 1 yard
Alright nevermind, imma delete this answer.
Answer: $5.40
Step-by-step explanation:
1 and 2/3 yards costs $9
5/3 yards costs $9 <--- changes 1 and 2/3 to improper
5 * 1/3 yards costs $9 <---- 5/3 = 5 * 1/3
1/3 yard costs $9/5 = $1.80 <--- divides the ratio by 5
1 yard costs $1.80 * 3 = $5.40

Answer:
x = 4
Step-by-step explanation:
(7x - 2) + (3x + 9) = 10x + 7
(10x + 7) + (8x - 6) = 18x + 1
18x + 1 = 73
18x = 72
72/18 = x
x = 4

Answer:
Last Choice / D
Step-by-step explanation:
you want to isolate v!
E = 1/2 m v^2
multiply both sides by 2
2E = mv^2
divide both sides by m
2E/m = v^2
square root both sides
v = ±[tex]\sqrt{2E/m}[/tex]
please click heart to give thanks :)
Answer:
[tex]D.v= \± \sqrt{\frac{2E}{m}}[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\Kinetic\ Energy\ possessed\ by\ an\ object=\frac{1}{2}mv^2\\Hence,\\E_k=\frac{1}{2}mv^2\\2E=2*\frac{1}{2}mv^2 [Multiplying\ both\ the\ sides\ with\ 2]\\2E=mv^2\\\frac{2E}{m}=\frac{mv^2}{m}[Dividing\ both\ the\ sides\ by\ m]\\\frac{2E}{m}=v^2\\Now,\\As\ v\ could\ be\ positive\ or\ negative\ but\ its\ square(v^2)\ would\ always\ be\ positive.\\[/tex]
[tex](\± v)^2= v^2\\Hence,\\\frac{2E}{m}= (\±v)^2 \\\sqrt{\frac{2E}{m}} = \±v\\Or,\\ v= \± \sqrt{\frac{2E}{m}}[/tex]

Write an express for the perimeter of the figure shown by combing like terms.
9514 1404 393
Answer:
28k
Step-by-step explanation:
The perimeter is the sum of the four equal-length sides:
P = 7k +7k +7k +7k
P = k(7 +7 +7 +7)
P = 28k . . . . perimeter of the rhombus
__
Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.
Scientists are preparing two satellites to be launched. The equation y=8200xy=8200x represents the number of miles, yy, that the satellite, Space Explorer B, flies in xx hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours. How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?
Answer:
It flies 380 miles fewer
Step-by-step explanation:
The correct question is as follows;
Scientists are preparing two satellites to be launched. The equation y=820x represents the number of miles, y, that the satellite, Space Explorer B, flies in x hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours. How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?
Solution;
For explorer B
The equation is;
y = 8200x
This mean that in 1 hour, it flies 820 miles
For explorer A
28,800 miles in 24 hours
In one hour, we have 28,800/24 = 1,200 miles
The number of fewer miles that explorer A travels will be ;
1200 miles - 820 miles = 380 miles fewer

7(5a − 4) − 1 = 14 − 8a
Answer:
A=1
Step-by-step explanation:
7(5a-4)-1=14-8a
35a-28-1=14-8a
35a-29=14-8a
43a-29=14
43a=43
a=1
Answer:
41/43
Step-by-step explanation:
7(5a - 4) - 1 = 14 - 8a
35a - 28 - 1 = 14 - 8a
35a - 27 = 14 - 8a
35a + 8a = 14 + 27
43a = 41
a = 41/43
