question
(60-5.8) ÷ 5 - 3^2
can you please explain it in an essay type like words and not just show me the answer I need it to show me how you got the answer don't give me just the answer
Answer:
1.84
Step-by-step explanation:
First you solve what is in the parenthesis.
60 - 5.8 = 54.2
The equation is now 54.2 ÷ 5 - 3^2
Now, you do the exponents. 3^2 = 9 since 3 to the second power is just another way to write 3 x 3.
Your equation is now 54.2 ÷ 5 - 9
You then divide 54.2 ÷ 5
54.2 ÷ 5 = 10.84
The last equation is 10.84 - 9
10.84 - 9 = 1.84
Answer:
Answer 1.84.

25π in²
10π in²
100π in²
400π in²
Answer:
100π in²
Step-by-step explanation:
i just took the test :)
The surface area of the ball is 100π square inches. The correct option is C.
How to calculate the surface area of a sphere?The formula for the surface area of a sphere is:
Surface Area = 4πr²
Where r is the radius of the sphere.
Since the basketball has a diameter of 10 in, the radius is half of that, which is 5 in.
Substituting the radius into the formula, we get:
Surface Area = 4π(5²)
Surface Area = 4π(25)
Surface Area = 100π
Therefore, the surface area of the basketball is 100π in².
So the surface area is 100π in².

Mrs.Davis deposits $8,000 into each of 2 savings accounts account 1 earns 6.5% simple interest account 2 earns earns 3% simple interest what’s the difference between the amounts of interest in account 1 and account 2 after 6 years?
Answer:
$1680
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
Account 1:
I = (8000)(0.065)(6)
I = $3,120
Account 2:
I = (8000)(0.03)(6)
I = $1,440
$3120 - $1440 = $1680

Answer:
x = 18.45
Step-by-step explanation:
Given that,
Chipper Jones get paid = [tex]1.23\times 10^6[/tex]
Alex get paid = [tex]2.27\times 10^7[/tex]
Let Alex get x times paid than chipper i.e.
[tex]{x}=\dfrac{A}{C}\\\\x=\dfrac{2.27\times 10^7}{1.23\times 10^6}\\\\x=18.45[/tex]
Hence, Alex gets paid 18.45 times than the Chipper.
Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2 what is the maximum
Answer:
Maximum = 61.1
Step-by-step explanation:
Given - Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2
To find - What is the maximum ?
Proof -
We have to find which candidate got highest votes in the election .
For this, we first arrange all 15 in ascending order i.e. lowest to highest.
Now,
The arrangement is like this -
43.2,
43.4,
47.9,
49.2,
49.6,
49.7
50.1,
50.7,
51.2,
53.9,
55.1,
57.4,
58.8,
60.7,
61.1
From this , we get
Lowest votes = 43.2
Highest votes = 61.1
⇒Maximum = 61.1

There is a 0.9987 probability that a randomly selected 31-year-old male lives through the year. A life insurance company charges $186 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit. Complete parts (a) through (c) below.
Parts a through c is missing and it is;
a) From the perspective of the 33-year-old male, what are the monetary values corresponding to the two events of surving the year and not surviving?
The value corresponding to surviving the year is $_____.
The value corresponding to not surviving the year is $_____.
b) If the 33-year-old male purchases the policy, what is his expected value?
The expected value is $_____.
c) Can the insurance company expect to make a profit from many such policies? Why?
_____ because the insurance company expects to make an average profit of $_____ on every 33-year-old male it insures for 1 year.
Answer:
A) the value that corresponds to surviving the year = - $186
The value corresponding to not surviving the year = $99814
B) μ = -$56
C) Yes, the company can make a profit from many such policies because it makes an average profit of $56 on every 31 year old male it insures for 1 year.
Step-by-step explanation:
A) The company charges $186 for insuring. Thus;
Amount paid out = - $186
Therefore, the value that corresponds to surviving the year = - $186
Therefore, the value corresponding to not surviving the year = $100000 - $186
The value corresponding to not surviving the year = $99814
B) since probability that a 31 year old male survives is 0.9987, then;
Probability that a male doesn't survive is;
P(doesn't survive) = 1 - 0.9987
P(doesn't survive) = 0.0013
The expected value is calculated from;
μ = Σx•P(x) = (0.0013 × 99814) + (-186 × 0.9987)
μ = -$56
C) Yes, the company can make a profit from many such policies because it makes an average profit of $56 on every 31 year old male it insures for 1 year.

How much larger is the circumference of circle A than the circumference of circle B?
Give your answer to one decimal place.
diameter of circle A is 13 and B is 8
Answer:
Circumference of Circle A is about 16 units larger than the Circumference of Circle B
Step-by-step explanation:
Formula for Circumference of a circle = πd
Where, d = diameter of circle
Thus:
Circle A diameter = 13
Circle B diameter = 8
Therefore:
Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)
Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)
✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16
Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B

A rectangle has a length of (x + 3) centimeters and a width of image x centimeters. If the perimeter is 24 centimeters, what is the length of the rectangle? A. 9 cm B. 3 cm C. 14 cm D. 7 cm PLEASE HELP WILL MARK BRAINLIEST.
Answer:
The length of the rectangle is 9 cm.
Step-by-step explanation:
Given: The length of rectangle(l) = (x+3) cm and a width of rectangle (w) = cm a
Also, perimeter of rectangle is 24 cm.
Perimeter of rectangle is to add the lengths of all the four sides.
Perimeter of rectangle (P) is given by;
P=2(l+w)
Substituting the value of P = 24 cm , l = (x+3) cm and w =
then,
Divide by 2 both sides of an equation;
Combine like terms;
Subtract 3 from both the sides we get;
Simplify:
Multiply both sides by we get
Therefore, length of rectangle(l) = (x+3) = 6+3 = 9 cm
