A circular flower bed is 22 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi
Answer:
326.6 m^2
to nearest tenth.
Step-by-step explanation:
The radius of the flower bed = 1/2 * 22 = 11m
The radius of the whole area included the sidewalk = 11 + 4 = 15 m
So the area of the sidewalk = area of the whole - area of flower bed
= 3.14 * 15^2 - 3.14* 11^2
= 326.6 m^2.

How many unique ways are there to arrange the letters in a word OPAL.
Answer:
24.
Step-by-step explanation:
We can use the factorial function to find the number of unique arrangements in a word.
There are 4 unique characters in 'OPAL'. As such, 4! = 24.
In the case that there were repeating characters, such as 'OPALA', then we would divide by the factorial of the number of repeating letters. That looks something like this:
[tex]\frac{5!}{2!} = 60[/tex]
Hope this helped.
Answer:
i think 24 beacuse opal has 4 letters and then u mutiply it by 6 and get 24

Write a division problem such that the quotient is the same as 3/8÷3/5
Answer:
[tex]\frac{5}{2}[/tex] ÷ [tex]\frac{20}{5}[/tex]
Step-by-step explanation:
[tex]\frac{3}{8}[/tex] ÷ [tex]\frac{3}{5} =\\[/tex]
[tex]\frac{3}{8} *\frac{5}{3} =[/tex]
[tex]\frac{15}{24} = \frac{5}{8}[/tex]
So we need a division problem that equals [tex]\frac{5}{8}[/tex]
[tex]\frac{5}{8} =\frac{25}{40}[/tex]
[tex]\frac{5}{2} *\frac{5}{20}[/tex]=
[tex]\frac{5}{2}[/tex] ÷ [tex]\frac{20}{5}[/tex]
Answer:
Step-by-step explanation:When we divide this we got . First we need to check if we can divide numerator by numerator, denominator by denominator. We can not. Then we multiply first fraction by other but in other we use reciprocal value.
Write an equation for the nth term of the geometric sequence below: (Equation NEEDS to be written as gn=7(5)^(n-1) or as gn=2/3(1/4)^(n-1) NOTICE NO SPACES & using ^ to represent an exponent)
Answer:
You didn't give the geometric sequence in question.
But to find the nth term of a geometric sequence, use the formula
Sn = ar^(n - 1)
Where a is the first term of the sequence
r is the common ratio of the sequence.
Example: To find the nth term of the geometric sequence
1/2, 1/4, 1/8, 1/16, ...
Here, a = 1/2
r = 1/4 ÷ 1/2 = 1/8 ÷ 1/4 = 1/16 ÷ 1/8 = 1/2.
Sn = (1/2)(1/2)^( n - 1)
Apply this method to the sequence you were given, it will be helpful.
what are all the key features of parabola
Answer:
A parabola has a vertex. The vertex is the point of a parabola where it changes direction. It also has an axis of symmetry which is an imaginary line that cuts it in two equal parts. A parabola may have x-intercepts ("zeros") which are points where the graph cross the x-axis. It may have x-intercepts which are points where the graph cross the x-axis.
75% of the temperatures are below what value? How do you know? 75% of the temperatures are above what value? How do you know? What conclusions can you draw about the temperature in Maryland?
Answer:
Complete Question:
Pick a city in Maryland and determine the average high temperatures for each month. Record this in a table.
a. Create a box-and-whisker plot for the data.
b. What is the median temperature?
c. 75%of the temperatures are below what value?How do you know? d. 75% of the temperatures are above what value? How do you know? e. What conclusions can you draw about the temperature in Maryland?
Step-by-step explanation:
TASK 3
The city picked is Baltimore, the year 2017.
The table is attached in picture #1.
a) The box-and-whisker plot is attached in picture #2.
b) The median is the central value of the distribution i.e:
42.4, 45.3, 46.8 | 54.7, 57.6, 66.0 | 69.1, 76.5, 80.6 | 85.8, 87.8, 90.0
where we marked with a tally the quartiles.
As we have 12 values, the average between the two central values will be the median :
M = (66.0 + 69.1) / 2 = 67.1 °F
c) 75% of the temperatures are below 83.2 °F.
Indeed, this value represents the third quartile. The position of the third quartile can be found by the formula:
3/4 · (n + 1) = 3/4 · (12 + 1) = 3/4 · 13 = 9.75
Therefore, since we did not get in integer position, the third quartile will be the average between the numbers in position 9 and 10:
q₀.₇₅ = (80.6 + 85.8) / 2 = 83.2 °F
d) 75% of the temperatures are above 50.8 °F.
Indeed, this value represents the first quartile. Similarly to point c), the position can be found by the formula:
1/4 · (n + 1) = 1/4 · 13 = 3.25
And therefore:
q₀.₂₅ = (46.8 + 54.7) / 2 = 50.8 °F.
e) Baltimore in 2017 had a median high temperature of 67.1 °F.
25% of the year the high temperatures were warmer than 83.2 °F, with no outlier above 90.0 °F which was the hottest temperature.
25% of the high temperatures were colder than 50.8 °F, with no outlier below 42.4 °F, which was the coldest high temperature.

A normal distribution has mean and standard deviation . Find the indicated probability for a randomly selected x-value from the distribution P (x > +3)
Answer:
0.0228
Step-by-step explanation:
Let us assume that the mean (μ) = 2 and the standard deviation (σ) = 0.5
Z score is a standard score used to measure the number of standard deviations by which the raw score (x) is above or below the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
For x > 3
[tex]z=\frac{x-\mu}{\sigma} =\frac{3-2}{0.5}=2[/tex]
From the normal distribution table, P(x > 3) = P(z > 2) = 1 - P(z < 2) = 1 - 0.9772 = 0.0228

percent of increase from 43 to 78
I need help plz
Answer: about 81.395%
Step-by-step explanation:
1) Subtract 78 - 43 to find the difference. ==> 35
2) Divide the increase by the original number, 43. ==> 35/43 = 0.8139534884
3) Multiply the answer by 100. ==> ~81.395%
BASICALLY: % increase = Increase ÷ Original Number × 100.
A basket contains five apples and seven peaches. You randomly select one piece of fruit and eat it. Then you randomly select another piece of fruit. The first piece of fruit is an apple and the second piece is a peach.
show work plz thanks!
Theoretical Probability Compound Events
Answer:
5/33
Step-by-step explanation:
five apples and seven peaches = 12 total
P( apple) = number of apples / total
= 5/12
No replacement since you ate it
four apples and seven peaches = 11 total
P( peach) = number of peach / total
= 4/11
P(apple, no replacement, peach) = 5/12 * 4/11 = 5/33

Solve for g.
8g + 3 = –6g + 13g + 13
Answer: g = 10
Step-by-step explanation: 8g + 3 = –6g + 13g + 13
8g + 3 = (–6g + 13g) + (13)
8g + 3 = 7g + 13
8g + 3 - 7g = 7g + 13 - 7g
g + 3 = 13
g + 3 - 3 = 13 - 3
g = 10
Answer:
[tex]8g + 3 = -6g + 13g + 13 : g = 10[/tex]
Step-by-step explanation:
[tex]8g+3=-6g+13g+13[/tex]
Add similar elements: [tex]-6g+13g=7g[/tex]
[tex]8g+3=7g+13[/tex]
Subtract [tex]3[/tex] from both sides:
[tex]8g+3-3=7g+13-3[/tex]
Simplify:
[tex]8g=7g+10[/tex]
Subtract [tex]7g[/tex] from both sides:
[tex]8g-7g=7g+10-7g[/tex]
Simplify:
[tex]g=10[/tex]

The units pf the digits of a two digits numeral is 8 if the digits are reversed the new number is 18 greater than the oringal number fund the oringal numeral
complete question:
The sum of the digits of a two-digit numeral is 8. If the digits are reversed, the new number is 18 greater than the original number. How do you find the original numeral?
Answer:
The original number is 10a + b = 10 × 3 + 5 = 35
Step-by-step explanation:
Let
the number = ab
a occupies the tens place while b occupies the unit place. Therefore,
10a + b
The sum of the digits of two-digits numeral
a + b = 8..........(i)
If the digits are reversed. The reverse digit will be 10b + a. The new number is 18 greater than the original number.
Therefore,
10b + a = 18 + 10a + b
10b - b + a - 10a = 18
9b - 9a = 18
divide both sides by 9
b - a = 2...............(ii)
a + b = 8..........(i)
b - a = 2...............(ii)
b = 2 + a from equation (ii)
Insert the value of b in equation (i)
a + (2 + a) = 8
2a + 2 = 8
2a = 6
a = 6/2
a = 3
Insert the value of a in equation(ii)
b - 3 = 2
b = 2 + 3
b = 5
The original number is 10a + b = 10 × 3 + 5 = 35

4. Nguyen is decorating the room for her sister's baby shower party. She is wrapping
Vietnamese conical hats in baby prints tissue paper to decorate the tables and some
shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If
she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
A 4,176 in2
B 8,975 in2
C 10,580 in2
D 36,267 in 2
Answer:
Step-by-step explanation:
Given the information of the conical hat
diameter of 16 inches => Radius = 8 inches height of 9 inches=> the slant height of the hat is (use Pythagorean Theorem)
[tex]s^{2}[/tex] = [tex]r^{2} + h^{2}[/tex]
<=> [tex]s^{2}[/tex] = [tex]8^{2} + 9^{2}[/tex]
<=> s = [tex]\sqrt{145}[/tex]
The area (without the base area) of tissue paper will she need to make one hat is:
SA = πrs in2
<=> SA = π*8*[tex]\sqrt{145}[/tex] in2
<=> SA =8 [tex]\sqrt{145}[/tex] π
=> the total tissue paper will she need for 21 hats is:
SA*21
= 8 [tex]\sqrt{145}[/tex] π*21
= 6352,18 in 2
