Answer:
6 + √27 / 3
6+ (3√3/3)
6+√3
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
So, the first step if simplifying the square root. Since 27/3 is equal to 9, you now have to take the square root of 9.
6+[tex]\sqrt{27/3}[/tex]=?
Since 27/3 is equal to 9, you now have to take the square root of 9.
6+[tex]\sqrt{9}[/tex]=?
The square root of 9 is 3.
So, you end up with this:
6+3=12

Is the square root of 3,600 rational or irrational? Explain.
Answer:
Rational. the square root of 3600 is a real, rational number, 60.
Step-by-step explanation:
Answer: Rational
Step-by-step explanation:
THREE WAYS TO DETERMINE:
If the number given is an integer, it is rational.
If the number given is fraction, it is rational.
If the number given is decimal, as long as it is terminating or repetitive decimal, it is rational. (Because then you can write it as a fraction which leads to the second point)
----------------------------------------------------------
Square root of 3600=60
60
It is an integer, which fits the first point
So, it is rationalHope this helps!! :)

Surface Area of a Cone:
In the three dimensional geometry, a cone is a shape that has a circular base and a lateral surface is associated with a vertex and the base.
The height of the cone is the length of a line segment that joins the base to the vertex of the cone.
The radius of the cone is the same as the radius of the base.
Surface area of a cone
(a) Lateral Surface Area
If
l
and
r
are the slant height and radius of a cone then its lateral surface area is given by the formula-
L
=
π
r
l
where
L
is the lateral surface area of the cone
(b) Total surface area
It is the sum of the area of the circular base and the lateral surface area of the cone.
S
=
L
+
π
r
2
S
=
π

l
+
π

Where
S
is the total surface area of the cone
Answer and Explanation:

7
c
m
and
15
c
m
respectively
r
=
7
c

Supervisor: "Representatives can credit a customer's account up to 20% of the full
amount due on the bill."
Representative: "My customer is threatening to leave our company. The customer's
bill is $333.00. I could offer the customer a credit of
$40.00
$48.00
$55.00
$60.00
$66.60
Answer:
$66.6
Step-by-step explanation:
Given that,
The customer's bill is $333.00. Representatives can credit a customer's account up to 20% of the full amount due on the bill.
We need to find 20% of $333 as follows :
[tex]=20\%\ \text{of}\ 333\\\\=\dfrac{20}{100}\times 333\\\\=\$66.6[/tex]
Hence, I could offer the customer a credit of $66.6. Hence, the correct option is (E).

(You will need a calculator.) Suppose you deposit $4800 into an account paying 3.2% simple annual interest and leave it there for six years.
Assuming that you make no other deposits or withdrawals, how much will the account hold at the end of that time?
Answer: $
(Round your answer to the nearest cent. Enter only the number without commas, not the dollar sign.)
Answer:
Step-by-step explanation:
principal (P) = $4800
Interest (I) = 3.2%
Time (T) = 6 years
Now
I = (P*T*R)/ 100 = (4800*3.2*6) / 100 = 921.6
Amount (A) = P + I = 4800 + 921.6 = $5721.6 = $5272

A university has 1,000 computers available for students to use. Each computer has a 250-gigabyte hard drive. The university wants to estimate the space occupied on the hard drives. A random sample of 100 computers showed a mean of 115 gigabytes used with a standard deviation of 20 gigabytes. What is the probability that a sample mean is between 111 and 119 gigabytes
Answer:
0.9545
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/standard error,
where x is the raw score
μ is the population mean
Standard error = σ/√n
n = random number of samples
σ is the population standard deviation.
For x = 111
z = (x-μ)/standard error
= 111 - 115/20/√100
= -4 /20/10
= -4/2
= -2
Probalility value from Z-Table:
P(x≤ 111) = P(x = 111) = 0.02275
For x = 119
z = (x-μ)/standard error
= 119 - 115/20/√100
= 4 /20/10
= 4/2
= 2
Probability value from Z-Table:
P(x≤ 119) = P(x = 119) = 0.97725
The probability that a sample mean is between 111 and 119 gigabytes
P(-Z<x<Z)
= P(-2< x < 2)
= P(x = 119) - P(x = 111)
= 0.97725 - 0.02275
= 0.9545
