The combined debt of the three most populous states is -2 × 10⁹ bigger than that of the three least populous states.
What is the arithmetic operator?Summarization, subtraction, division, and multiplication are the four fundamental mathematical operations covered under the term "arithmetic operators."
Given the combined debt of ;
Most populous = -1.02 × 10¹⁰
Least populous = -1 × 10¹⁰
Most populous - Least populous ⇒
( -1.02 × 10¹⁰) - (-1 × 10¹⁰)
⇒ -0.2 × 10¹⁰
Multiply and divide by 10
⇒ -0.2 × 10/10 × 10¹⁰
⇒ -2 × 10¹⁰/10
⇒ -2 × 10⁹
Hence "The combined debt of the three most populous states is -2 × 10⁹ bigger than that of the three least populous states".

Shane wrote: \large \frac{2\cdot3^4}{5^{^2}}
Who is correct and why?
a
Adam is correct because the negative exponent moves the base to the other side of the fraction bar and makes the exponent positive.
b
None of these are correct because the students did not add the exponents in the numerator and then subtract exponents since there is division.
c
Nick is correct because the negative exponent in the numerator moves the whole numerator into the denominator and makes the exponent positive.
d
Shane is correct because all that needs to be done is to make the negative exponents positive.
Answer:the answer is A:nick is correct
Step-by-step explanation:
Based on the fraction given of [tex]\large \frac{2\cdot3^{-4}}{5^{-2}}[/tex], the correct person is c. Nick is correct because the negative exponent in the numerator moves the whole numerator into the denominator and makes the exponent positive.
Why is Nick correct?When a number is being taken to the negative power, then it can be rewritten as a fraction where the number becomes the denominator and the numerator becomes 1.
The number, 2.3⁻⁴ can be written as:

Step-by-step explanation:
once we know what the domain and the range of a function is, this is very simple.
the domain is the interval or set of all valid x (input) values.
the game is the interval or set of all valid y (function result) values.
so, what are all the valid x values ? that means for how many months of collection can we use this function to see how many figurines he has ?
well, we can stay with 0 (what he currently has) and go up to 5 (because after 5 months he does not want to continue this behavior).
so, the domain is
0 <= x <= 5 if we allow also fractions of months as input (if this makes sense)
or
x € {0, 1, 2, 3, 4, 5} if we allow only whole numbers.
and the range ? what are the possible result values of the function ?
for x = 0 it starts with y (or f(x)) = 100.
x = 1 gives us 100 + 3×1 = 103
x = 2 gives us 100 + 3×2 = 106
x = 3, 100 + 3×3 = 109
x = 4, 100 + 3×4 = 112
x = 5, 100 + 3×5 = 115
so, the range is
100 <= y <= 115 if we allow fractions of months
or
y = f(x) € {100, 103, 106, 109, 112, 115} if we allow only whole months as values of x.
share £60 in the ratio 3:1
If we share $60 in the ratio 3:1, then each person will get is $45 and $15 respectively
Given,
The total amount = $60
The ratio = 3:1
Then the amount given to first person = 3x
The amount given to the second person = x
Given that the total amount is 60
Then the equation will become
x+3x=60
4x=60
x=[tex]\frac{60}{4}[/tex]
x=15
The amount given to the first person = 3x
Substitute the value of x in the equation
The amount given to the first person =3x

on monday ramon bought 5 zip disks. two days later the price of the discs were decreased by 1.50 per disk. leticia bought ten disks at the sale price and paid 22 more than ramon paid for 5 disks. what was the original price of a disk
The original price of a zip disk is; $1.4
How to Solve Algebra Word Problems?Let cost of zip sticks bought by Ramon be x. Thus;
Cost that Ramon paid = 5x
Now, we are told that 2 days later the price increased by $1.5 per disc. Thus, new cost = x + 1.5
Leticia bought ten disks at the sale price and paid 22 more than ramon paid for 5 disks. Thus, equation here is;
10(x + 1.5) = 5x + 22
Expand the bracket to get;
10x + 15 = 5x + 22
10x - 5x = 22 - 15
5x = 7
x = 7/5

In a survey the ratio of students who prefer muffins to bagels is 4 to 5 if the number of students surveyed who prefer muffins is 420 how many prefer bagels
In a survey where the ratio of students who prefer muffins to bagels is 4 to 5 and 420 prefer muffins, 525 students prefer bagels.
Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.
It can be expressed in different ways:
1) Use the ":" to separate the values : a : b
2) Use the word "to" : a to b
3) Write it in fraction: a / b
On the other hand, proportion is the equality of two ratios, such that
a : b = c : d
Given a proportion, the product of its means must be equal to the product of its extremes. That is:
ad = bc
If the ratio of students who prefer muffins to bagels is 4 to 5, and 420 students prefer muffins, the proportion can be written as:
4 : 5 = 420 : n
where n = number of students who prefer bagels
Solving for n,
4n = 5(420)
4n = 2100
n = 525
number of students who prefer bagels = 525

The distance between points A and B is 8 units.
We have been given two points A and B.
The coordinates of the points are A = (3,-7) B = (3,1)
We need to find the distance between points A and B.
Let d be the distance between points A and B.
Using distance formula,
d = √[(3 - 3)² + (1 - (-7))²]
d = √[0² + 8²]
d = √8²
