Which expression represents the distance between 4.7 and −11.2 on the number line? Drag and drop the correct expression into the box.
Answer:
15.9Step-by-step explanation:
[tex]\text{The formula of a distance between two points on a number line:}\\\\d=|a-b|\\\\\text{for}\ a\geq b:\ d=a-b\\=========================\\\\\text{We have}\ 4.7\ \text{and}\ -11.2.\ \text{Substitute:}\\\\d=4.7-(-11.2)=4.7+11.2=15.9[/tex]
The distance between 4.7 and -11.2 on the number line is 15.9.
Explanation:The distance between two points on a number line can be found by taking the positive difference between their coordinates. In this case, the distance between 4.7 and -11.2 is found by subtracting the smaller number from the larger number and taking the absolute value.
Distance = |-11.2 - 4.7| = |-15.9| = 15.9
Therefore, the correct expression is Distance = 15.9.

William Right broke his leg in an accidental fall. He has a deductible of $150 and a coinsurance payment equal to 20% percent of the cost less the deductible. The entire bill for medical services was $750.00.
How much did William pay? $
How much did the insurance company pay? $
We know that William
paid his deductible that amount is the $150.
Then William paid 20 percent of everything else. That's 20 percent of (750
minus 150), it is equal to 150.
Then the insurance company paid 80 percent of (750 minus 250), it is equal to
480.
Answer:
its is he payed 270 and insurance payed 480
Step-by-step explanation:
just simply add up the numbers to 750 and the only ones that go together are 270 + 480 = 750 hope it helps :)

If I spoke with 800 customers in 40 hours how many customers did I speak to every 30 minutes
Answer:
10 customers were spoken to in every 30 minutes
Step-by-step explanation:
First, we convert 40 hours into minutes by multiplying it with 60 [as 1 hour = 60 minutes]
So, 40 hours = 40*60 minutes
= 2400 minutes
In 2400 minutes, number of customers served = 800
In 1 minute, number of customers served = [tex]\frac{800}{2400}[/tex]
In 30 minutes, number of customers served = [tex]\frac{800}{2400}*30[/tex]
= [tex]\frac{800}{2400} * \frac{30}{1}[/tex]
= [tex]\frac{800*30}{2400*1}[/tex]
= [tex]\frac{24000}{2400}[/tex]
= 10
So,
10 customers were spoken to in every 30 minutes
Final answer:
You spoke with 10 customers every 30 minutes.
Explanation:
To find out how many customers you spoke to every 30 minutes, we can set up a proportion. We know that you spoke with 800 customers in 40 hours, which is equivalent to 2400 minutes. So, the proportion is:
800 customers / 2400 minutes = x customers / 30 minutes
Now, we can cross-multiply and solve for x:
800 * 30 = 2400 * x
x = 800 * 30 / 2400
x = 10
Therefore, you spoke with 10 customers every 30 minutes.

How do you take the limit of this
The limit of the function lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6) is DNE
To take the limit of the function lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6), we proceed as follows
Since we have the function lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6) and we want to take the limit, we proceed thus,.
First, we divide both the numerator and denominator by x⁴. So,
lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6) = lim x → ∞(x⁴ - 9x² + x)/x⁴ ÷ (x³ - x + 6)/x⁴
= lim x → ∞(x⁴/x⁴ - 9x²/x⁴ + x/x⁴ ÷ (x³/x⁴ - x/x⁴ + 6/x⁴)
= lim x → ∞(1 - 9/x² + 1/x³ ÷ (1/x - 1/x³ + 6/x⁴)
Now, taking the limit as x tends to infinity, we have that
= lim x → ∞1 - lim x → ∞9/x² + lim x → ∞1/x³ ÷ lim x → ∞1/x - lim x → ∞1/x³ + lim x → ∞6/x⁴
= (0 - 9/∞² + 1/∞³)/(1/∞ - 1/∞³ + 6/∞⁴)
= (0 - 9/∞ + 1/∞)/(1/∞ - 1/∞ + 6/∞)
= (∞ - 0 + 0)/(0 - 0 + 0)
= (∞)/(0)
= DNE
Write the equation of the line containing the point (3, –2) and having a slope of 2 in slope-intercept form.
The equation of a line containing the point (3, –2) and having a slope of 2, is y = 2x-8
What is an equation of a line?The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers. When we represent the equation geometrically, we always get a straight line.
Given that a line containing the point (3, –2) and having a slope of 2, we need to find the equation of the line,
So, the general equation of a line is y = mx+c
Where, m is the slope and c is the y-intercept.
Therefore,
y = 2x+c
Now, put x = 3 and y = -2 in the equation to find the value of c,
-2 = 3(2)+c
-2 = 6+c
c = -8
Put the value of c in the equation,
y = 2x-8
Hence, the equation of a line containing the point (3, –2) and having a slope of 2, is y = 2x-8

The rules of the order of operations tells you to multiply and divide in order from left to right.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. There are no parentheses in this problem, so start with exponents. Then, multiply and divide from left to right.
Hence, the rules of the order of operations tells you to multiply and divide in order from left to right.

what is the circumference of a circle p PB=29m
Answer:
The circumference of the given circle = 182.12 meters
Step-by-step explanation:
The circle P is given to us in which length of PB = 29 meter
Now, Since P is the center of the circle so PB will be the radius of the circle
So, Radius of the circle = 29 meter
We need to find the circumference of this circle with radius 29 meter
So, Circumference of the circle = 2π × radius of the circle
⇒ Circumference of the circle = 2 × 3.14 × 29
= 182.12 meter
Hence, The circumference of the given circle = 182.12 meters

A web server hosting company advertises 99.999 percent guaranteed network uptime. (a) how many independent network servers would be needed if each has 98 percent reliability? (round your answer up to the nearest whole number.) network servers (b) how many independent network servers would be needed if each has 89 percent reliability? (round your answer up to the nearest whole number.) network servers
a. The 50 independent network servers would be needed if each has 98% reliability.
b. Approximately 9 independent network servers would be needed if each has 89% reliability.
To calculate the number of independent network servers needed for a given level of reliability, we can use the following formula:
[tex][ \text{Number of servers} = \frac{1}{1 - \text{Reliability}} ][/tex]
a) For servers with 98% reliability:
[tex][ \text{Number of servers} = \frac{1}{1 - 0.98} = \frac{1}{0.02} = 50 ][/tex]
Therefore, 50 independent network servers would be needed if each has 98% reliability.
b) For servers with 89% reliability:
[tex][ \text{Number of servers} = \frac{1}{1 - 0.89} = \frac{1}{0.11} \approx 9 ][/tex]
Therefore, approximately 9 independent network servers would be needed if each has 89% reliability.
