An eight ft board is cut into two pieces. One piece is 2 ft longer thant he other. How long are the pieces?
Answers
Answer: 6 ft and 2 ft
Step-by-step explanation:
Answer:
6ft and 2ft
Step-by-step explanation:
8ft board ÷ 2 pieces = 4ft each
4ft and 4ft boards. But one of them is longer by 2ft so:
4ft - 2ft = 2ft
4ft + 2 ft = 6ft
So, one piece is 2ft and the other piece is 6ft
In a given year, the population of Metro City is 7420, and the population is decreasing by 152 people per year. The population of Smallville is consistently 1200 less than half of Metro City. Determine how long it will take for Smallville's population to reach 2282.
Which answer provides the correct equation and solution for the situation, where x represents the number of years?
A. The equation is 2282=2(7420−152x)+1200. It will take 45.26 years for the population of Smallville to be 2282 people.
B. The equation is 2282=2(7420−152x)+1200. It will take 45.26 months for the population of Smallville to be 2282 people.
C.The equation is 2282=12(7420−152x)−1200. It will take 3 months for the population of Smallville to be 2282 people.
D. The equation is 2282=12(7420−152x)−1200. It will take 3 years for the population of Smallville to be 2282 people.
Answers
Answer:
The correct option is D.
Step-by-step explanation:
Let x denote the years.
The information provided is:
The population of Metro City is 7420.The population is decreasing by 152 people per year.The population of Smallville is consistently 1200 less than half of Metro City.From the provided data derive the equation for the population of Smallville x years after as follows:
[tex]Y = [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]
The population of Smallville is 2282 after x years.
Compute the value of x as follows:
[tex]2282= [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]
[tex]\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3[/tex]
Thus, the time it will take for Smallville's population to reach 2282 is 3 years.
The correct option is D.

How long is 75% of a 24-hour day?
Answers
Answer:
18 hrs
Step-by-step explanation:
6hrs is 25%, so 6 times 3 is 18, Hope This Helps!
75% of a 24-hour day is 18 hour.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
75% of a 24-hour day
let 75% of 24 hour day be x.
So, 75% of 24 = x
x= 75/100 x 24
x= 3/ 4 x 24
x= 18 hours
Hence, 75% of a 24-hour day is 18 hour.

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 77 feet per second. The elevator for the miners descends 1313 feet per second. One day, the equipment elevator begins to descend. After 2929 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 1616 seconds? At that time, which elevator is deeper?
Answers
Answer:
The position of the equipment elevator is 315 feet deep.
The position of the elevator of the miners is 208 feet deep.
At that time, the equipment elevator is deeper.
Step-by-step explanation:
Observation: Seems the numbers are doubled. 77 instead of 7; 1313 instead of 13; 2929 instead of 29; and 1616 instead of 16.
Hence, the question is:
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second. The elevator for the miners descends 13 feet per second. One day, the equipment elevator begins to descend. After 29 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 16 seconds? At that time, which elevator is deeper?
Step-by-step explanation:
From the question,
For the equipment elevator
Speed= 7 feet/second
For the elevator of the miners,
Speed= 13 feet/second
To determine the positions of each elevator relative to the surface, we will determine the distance each of the elevator descends.
From the formula
Speed= Distance / Time
Then,
Distance = Speed × Time
From the question,
The equipment elevator begins to descend and after 29 seconds, the elevator for the miners begins to descend. To determine the position of each elevator after another 16 seconds. That is, the equipment elevator descends for a total of (29+16) seconds and the elevator of the miners descends for 16 seconds.
For the equipment elevator
Speed= 7 feet/second
Time = 29 + 16 seconds = 45 seconds
From, Distance = Speed × Time
∴ Distance = 7 feet/second × 45 seconds
Distance = 315 feet
Hence, the position of the equipment elevator is 315 feet deep.
For the elevator of the miners
Speed = 13 feet/second
Time = 16 seconds
Distance = Speed × Time
∴ Distance = 13 feet/second × 16 seconds
Distance = 208 feet
Hence, the position of the elevator of the miners is 208 feet deep.
At that time the equipment elevator is deeper.

10•f(7)+9•g(-1)=
Answers
Answer:
-1
Step-by-step explanation:
By the rule of the functions, 10.[f(7)] + 9[g(-1)] = -1
From the graph attached,
Blue curve represents the function 'f' and the purple curve represents function 'g'.
We have to find the value of the expression with the help of the graph attached,
For a function y = f(x), (x, y) is a point on the curve representing the values on x-axis and y-axis respectively.
Given expression → 10[f(7)] + 9[g(-1)]
Since, y = f(x)
Therefore, for x = 7 y-value will be,
y = f(7) = -1
Similarly, y-value of the function 'g' at x = (-1) will be,
y = g(-1) = 1
By substituting these values in the expression,
10.[f(7)] + 9.[g(-1)] = 10(-1) + 9(1)
= 10(-1) + 9
= -10 + 9
= -1
Therefore, 10.[f(7)] + 9[g(-1)] = -1 will be the answer.

39 divided by the amount of candy bars (13) is 3. Which means each candy bar weighs 3 ounces. So 3 times 25 is 75.
A square corner of 16 square centimeters is removed from a square paper with an area of 9x2 square centimeters. A square. Most of the square is shaded blue. In the bottom right of the square is a smaller square, outlined in a dashed line, and not shaded. Which expression represents the area of the remaining paper shape in square centimeters? (x – 7)(x – 9) (3x – 2)(3x – 8) (3x – 4)(3x + 4) (9x – 1)(x + 16)
Answers
Answer:
(3x - 4) (3x + 4)
Step-by-step explanation:
Area of the square paper = 9x^2 square centimeters
Area of the square corner = 16 square centimeters
The area of the square corner is removed from area of the square paper.
That is,
9x^2 - 16
Factorise by finding the square root of each term
9x^2
Square root of 9x^2 = 3x
Check:
3x * 3x = 9x^2
Square root of 16 = + or - 4
9x^2 - 16 = (3x - 4) (3x + 4)
Check:
(3x - 4) (3x + 4)
9x^2 + 12x - 12x - 16
= 9x^2 - 16

5^3 / 5^-3 oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
Answers
Answer: 5^3 / 5^-3 = 5^6 = 15,625
Step-by-step explanation:
Ok, you may find useful for problems like this the next two relations:
[tex]x^a*x^b = x^{a + b}[/tex]
[tex]x^a/x^b = x^{a - b}[/tex]
Now we have the equation:
5^3/5^-3
We have a quotient, then we need to use the second relationship, where:
x = 5
a = 3
b = -3
5^3/5^-3 = 5^(3 - (-3)) = 5^(3 + 3) = 5^6 = 15,625

Another term to represent Unit Rate is?
Constant of Proportionality
Slope
Rate of Change All of the Above
None of the Above
Answers
Answer:
All of the above.
Step-by-step explanation:
In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.
Therefore, the unit rate is the same as the rate of change.
And the rate of change is synonymous with the slope.
The constant of proportionality is simply the slope/rate of change for proportional equations.
Therefore, the constant of proportionality is also another word for the unit rate.
Our answer is hence all of the above.
