Answer: I’m pretty sure its A on e2020
Step-by-step explanation:
It is an obligation to pay, but the spender has some control over the amount.
Option A is the correct answer.
We have,
The reason that a data usage bill for a smartphone is an essential (variable) expense is that it is an obligation to pay.
In other words, the phone service is necessary for the phone to function properly, and therefore, the bill must be paid.
However, the spender has some control over its amount by managing their data usage, such as turning off data for certain apps or using Wi-Fi instead of cellular data.
This means that while the bill cannot be eliminated entirely, the spender can take steps to reduce the amount owed.
Statement b is incorrect because while the bill cannot be eliminated entirely, it can be reduced by managing data usage.
Statement c is incorrect because the amount of the bill is not expected to be the same every month, as it will depend on how much data is used. Statement d is incorrect because while bills for services rendered may be a priority, they do not necessarily have a higher priority than other types of essential expenses, such as food or housing.
Thus,
It is an obligation to pay, but the spender has some control over the amount.

John wants to send a letter to peter who lives on tesla street john does not remember the house number however he knows that it has 4 digits it is a multiple of 5 and 7 and that that the last digit is 0 what is the minimum number of letters that john has to send to be sure that peter receives his letter
Answer: 137 letters.
Step-by-step explanation:
The data is:
The number has 4 digits.
The number is a multiple of 5
The number is a multiple of 7
The last digit is a 0.
Then, let's find all the possible numbers that met these conditions.
Our number can be formed with 4 digits, A, B, C and D.
D is the last one, so we have D = 0.
So the number is: ABC0
We know that all the numbers that end with 0 are multiples of 5, so that condition does not matter.
Now, a number is divisible by 7 if:
Take the last digit of the number, double it and subtract it to the remaining number, if the result is multiple of 7, then the initial number is a multiple of 7.
In this case the last digit is 0, so when we double it and subtract it, we actually are not changing the other 3 digits.
Then we have that:
ABC must be a multiple of 7.
So now our problem reduces to find the number of 3-digit numbers that are multiples of 7.
The first multiple of 7 that has 3 digits is:
7*15 = 105.
And the largest possible 3 digit number is 999, now let's try to divide it by 7 to see if this is also a multiple of 7.
999/7 = 142.7
the quotient is not integer, so 999 is not a multiple of 7.
The next option is 998, we can do the same here:
998/7 = 142.6
And so on, we will find that the largest 3 digit multiple of 7 is:
994, such that:
7*152=994.
Then we have:
Smallest: 7*15 = 105
Largest: 7*152 = 994.
Then the number of multiples of 7 between 999 and 100 will be equal to the difference between the quotients between the multples and 7.
105/7 = 15
994/7 = 152
152 - 15 = 137
So we have 137 multiples of 7 with 3 digits.
Then we have 137 4-digit numbers, that end with a zero and also are divisible by 5 and 7.
So John must send 137 letters if he wants to be shure that Peter will get the card.

How do you write 89,000 in scientific notation
Answer:
8.9 × 10^{4}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 89,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 89,000
New Number: 8.9000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 8 . 9 0 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.9 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
8.9 x 10^{4}
Step 4
Check your work:
10^{4} = 10,000 x 8.9 = 89,000

Answer:
-1
Step-by-step explanation:
Find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= (-3-5)/(6 - -2)

= -8/8
= -1
Answer:
The answer is option CStep-by-step explanation:
The slope of a line given two points can be found by using the formula

an object is moving at a speed of 6 miles per month. express this speed in feet per hour. Don’t have to round anything up
Answer: 44 feet.
Step-by-step explanation: If the object is moving at a speed of 6 miles per month, that's 6 miles for every 720 hours at the very least. That's 1 mile for every 120 hours. That's 5280 feet for every 120 hours. The object is moving 44 feet every hour.
The speed of the object is 43.39 feet per hour.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
We have,
6 miles = 1 month
1 miles = 5280 feet
1 month = 730 hours
Now,
6 miles = 6 x 5280 feet
6 miles = 31680 feet
So,
31680 feet = 730 hours
Divide both sides by 730.
31680/730 feet = 1 hour
43.39 feet = 1 hour
Thus,
Speed is 43.39 feet per hour.

The perimeter of a square courtyard is 144 m. Find the cost of cementing it at the rate of £5 per m². *
Answer:
the cost is £ 6,480
Step-by-step explanation:
given:
The perimeter of a square courtyard is 144 m
find:
the cost of cementing it at the rate of £5 per m².
Perimeter = 4 Sides
144 = 4 S
S = 144/4
S = 36
Area = S²
A = 36²
A = 1296 m²
cost of cementing the area = 1296 m² x £5 per m² = £ 6,480
therefore,
the cost is £ 6,480

Find the equation of the line. Use exact numbers.
Answer:
y=-3/2x+3
Step-by-step explanation:
The slope is -3/2x because it's going down 3 and to the right 2.
And it intercepts the y-axis at 3. Thus, 3 is the y-intercept.
Answer:
y = -3/2 x +3
Step-by-step explanation:
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
The y intercept is 3
Now to find the slope
Pick two points on the line
( 0,3) and ( 2,0)
m = ( y2-y1)/(x2-x1)
= ( 0-3)/(2-0)
= -3/2
The equation of the line is
y = -3/2 x +3
