Answer:
(-4 1/8)
Step-by-step explanation:
-6 1/4 - (-2 1/8) The subtraction cancels out the subtraction.
-6 1/4 + 2 1/8
-6 + 2 = -4 The whole numbers are independent in this case.
1/4 + 1/8 Find the least common multiple
Multiples:
4| 4_8_12
8| 8_16
8 is the least common multiple
4 goes into 8 twice so multiply the top and bottom by 2
4 * 2 = 8 1 * 2 = 2
-2/8 + 1/8 = -1/8
add that to -4

Answer:
[tex]a_{87} = -1020[/tex]
Step-by-step explanation:
Given:
The given AP is.
12,0,-12,......
[tex]n=87[/tex]
The first term of an AP [tex]a=12[/tex]
Common difference [tex]d=0-12=-12[/tex]
We use the the formula for nth term of an AP.
[tex]a_{n} = a+(n-1)d[/tex]
for 87th term
[tex]a_{87} = 12+(87-1)(-12)[/tex]
[tex]a_{87} = 12+(86)(-12)[/tex]
[tex]a_{87} = 12+(-1032)[/tex]
[tex]a_{87} = 12-1032[/tex]
[tex]a_{87} = -1020[/tex]
Therefore, The 87th term of given series is -1020.

Zoey is 362 meters below sea level while visiting a part of Israel. She descends 71 meters to visit the Dead Sea. Which integer represents the elevation, in meters, of the Dead Sea?
In the beginning, 362 meters below sea level, or -362 meters (if we consider sea level as 0).
Because the Dead Sea is 71 meters below where she was, the equation to solve this would be
-362 - 71 = -433
The answer is -433.
Hope this helps!
Since Zoey is 362 meters below sea level while visiting a part of Israel and she descends 71 meters to visit the Dead Sea, the integer that represents the elevation, in meters, of the Dead Sea is a) -433.
How the elevation is computed:We can use the mathematical operation of subtraction to determine the elevation of the Dead Sea as follows:
The present elevation of Zoey = -362 meters

What is the domain of the function f(x)=2/5 sqrt x
The domain of the function f(x) = (2/5) * sqrt(x) is all real numbers x ≥ 0, or in interval notation, [0, ∞). This is because square roots are only defined for non-negative real numbers.
Explanation:The domain of a function refers to all possible values that can be input into the function, usually represented by 'x'. For the given function f(x) = \frac{2}{5} \sqrt{x}, we need to determine the set of x-values for which the function is defined. Since we cannot take the square root of a negative number in the set of real numbers, the smallest value for 'x' must be 0. Thus, the domain of the function f(x) = \frac{2}{5} \sqrt{x} includes all real numbers greater than or equal to 0.
This is written mathematically as “x ≥ 0” or in interval notation as [0, ∞). It's important to note that, for real numbers, square roots are only defined for non-negative values, which is why the domain starts at 0 and continues to positive infinity.

Four soccer teams compete in a tournament. Each team faced each other exactly once with no ties allowed. A team received 1 point for each win.
The results
Team 1 had 1 point
Team 2 had 3 points
Team 3 had 1 point
How many points did team 4 have?
Answer:
1 point
Step-by-step explanation:
The number of games in the tournament is:
₄C₂ = 6
Another way to look at it: Team 1 plays 3 games against Team 2, 3, and 4. Then, Team 2 plays 2 games against Team 3 and 4 (Team 2 already played Team 1). Finally, Team 3 plays a game against Team 4. So the total is 3 + 2 + 1 = 6.
If there's a total of 6 games, then there's a total of 6 points. So if x is the number of points Team 4 has:
x + 1 + 3 + 1 = 6
x + 5 = 6
x = 1
Team 4 has 1 point.

Answer:
5,46 inches per months
Step-by-step explanation:
1 year = 12 months
The average precipitation per month is :
65,52 inches ÷ 12 = 5,46 inches per months
HOPE THIS HELPED ;3
The predicted amount of precipitation received between the end of March and the end of June is 0 inches.
Explanation:To predict the amount of precipitation received between the end of March and the end of June, we need to find the difference in total precipitation between those two months. According to the given information, the total precipitation in inches for each month is as follows:
March: 4 inches
April: 2 inches
May: 0 inches
June: 4 inches
To find the amount of precipitation received between the end of March and the end of June, we can subtract the total precipitation at the end of March from the total precipitation at the end of June:
Total precipitation at the end of June - Total precipitation at the end of March = 4 inches - 4 inches = 0 inches
Therefore, the predicted amount of precipitation received between the end of March and the end of June is 0 inches.
Cassidy has saved $8,000 this year in an account that earns 9% interest annually. Based on the rule of 72, it will take about years for her savings to double.
Answer:
The number of years in which saving gets double is 8 years .
Step-by-step explanation:
Given as :
The principal amount saved into the account = p = $8,000
The rate of interest applied = r = 9%
The Amount gets double in n years = $A
Or, $A = 2 × p = $8,000 × 2 = $16,000
Let the number of years in which saving gets double = n years
Now, From Compound Interest method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]
Or, 2 × p = p × [tex](1+\dfrac{\textrm r}{100})^{\textrm n}[/tex]
Or, $16,000 = $8,000 × [tex](1+\dfrac{\textrm 9}{100})^{\textrm n}[/tex]
Or, [tex]\dfrac{16,000}{8,000}[/tex] = [tex](1.09)^{n}[/tex]
Or, 2 = [tex](1.09)^{n}[/tex]
Now, Taking Log both side
[tex]Log_{10}[/tex]2 = [tex]Log_{10}[/tex] [tex](1.09)^{n}[/tex]
Or, 0.3010 = n × [tex]Log_{10}[/tex]1.09
Or, 0.3010 = n × 0.0374
∴ n = [tex]\dfrac{0.3010}{0.0374}[/tex]
I.e n = 8.04 ≈ 8
So, The number of years = n = 8
Hence, The number of years in which saving gets double is 8 years . Answer
when the function p(x) is divided by x - 1 the quotient is x^2 + 7 + 5/x - 1. State P(x) in standard form.
Answer:
We know that
P(X) = Dividor × Quotient
So dividor = x-1
Quotient = x2 + 7 + 5/x-1
So,
P(x) = x3 - x2 + 7x -2
Step-by-step explanation:
Taking LCM of quotient we will get
(x3 - x2 + 7x - 2)/(x-1)
Now by multiplying the above equation with x-1,
Only thing remaining will be
x3 - x2 + 7x - 2
This is P(x).
The polynomial p(x) in standard form, when given the quotient formed from dividing p(x) by (x - 1), is x^3 - x^2 + 7x - 2.
Explanation:The function p(x) can be expressed in standard form by multiplying divisor (x - 1) by the quotient, (x^2 + 7 + 5/(x - 1)) according to polynomial division rules. To get p(x), you multiply the quotient by the divisor and add the remainder. However, since there is no remainder mentioned, we assume it's zero and ignore it.
Therefore, p(x) is (x - 1)(x^2 + 7 + 5/(x - 1)). To simplify further, distribute (x - 1) across each term in the parenthesis:
Multiplying (x - 1) by x^2 yields x^3 - x^2. Multiplying (x - 1) by 7 results in 7x - 7. Multiplying (x - 1) by 5/(x - 1), the (x - 1) factors cancel, leaving 5.So, the polynomial p(x) is x^3 - x^2 + 7x - 7 + 5 or, simplified further, x^3 - x^2 + 7x - 2.

The perimeter of a square depends on the length of its sides. Answer the questions below regarding the relationship between the perimeter of the square and the length of one side of the square.
The perimeter of a square is calculated by multiplying the length of one side by 4.
The perimeter of a square is the sum of all four sides. Since a square has equal sides, you can find the perimeter by multiplying the length of one side by 4. The formula for the perimeter of a square is P=4s, where P is the perimeter and s is the length of one side.
For example, if the length of one side is 5 units, the perimeter would be 4 * 5 = 20 units. If the length of one side is 8 centimeters, the perimeter would be 4 * 8 = 32 centimeters.
